EPDM Liquid Roof Applications: What You Should Know

If you search for RV roofing materials, you will likely come across a lot of information and resources for EPDM liquid roofing. This is one of the most popular options for RV owners who want a cost-effective, durable roofing solution that requires little maintenance and upkeep. Other roofing materials, such as fiberglass, are going to need much more routine care, and often cost more to install and maintain over time.

What is EPDM, though?

EPDM stands for Ethylene Propylene Diene Monomer, which is just a technical term for a synthetic rubber compound. This material is highly stable and flexible, and creates a binder during the curing process to create vulcanized EPDM rubber membranes and sheeting. For liquid roofing, the binding and curing process is not completed in the manufacturing process. The compound is left in a liquid state and combined with other ingredients to allow it to air-dry and cure to a flexible, watertight seal across the entire surface of the roof.

EPDM includes added oils to assist with curing and flexibility. This is part of what makes EPDM liquid roof applications so easy and effective. However, this material is also not resistant to oils or most solvents, which means that repair and maintenance products need to be compatible with EPDM or they will cause damage and premature deterioration and aging. The leading brands of RV maintenance, cleaning, and repair products all have EPDM-compatible products, however, so that shouldn’t be difficult to find if you know what you are looking for.

DIY EPDM Liquid Roof Applications

One of the biggest selling points, for many RV owners, is that liquid roofing can be done by just about anyone. Using a brush and roller or a squeegee, you can simply pour and spread the product across your RV roof and allow it to air dry to cure after you finish. RVs aren’t the only place you will find this roofing material, although they are among the most popular for liquid roofing. EPDM is also used for:

  • Mobile homes
  • Commercial buildings
  • Any building with a low slope or flat roof

Unlike sheet roofing and seamed products, liquid roofing creates a strong, seam-free membrane across the roof, which offers more protection and requires fewer repairs over time. This, combined with its affordability and versatile application, is what makes EPDM liquid roofing such a popular choice.

Frequently Asked Questions about EPDM Liquid Roof Applications

How long does EPDM take to cure?

Drying time depends on a number of factors, including humidity, temperature, and coating thickness. Typically, EPDM will be dry to the touch within a few hours of application. Full curing usually takes about 24 hours. Plus, the formula is designed to continue curing and bonding, so it will get stronger over time.

How much is EPDM liquid roofing?

Costs vary depending on the brand and type of liquid roofing that you choose, but a single gallon ranges from about $50 to $100. You can pick up 4-gallon or 5-gallon buckets for a few hundred bucks, in most cases. Keep in mind that a single gallon provides 40-45 square feet of coverage, so you may need less than you think.

Can I use leftover liquid roofing for maintenance and repairs?

If you have more materials than you need to replace or recoat your RV roof, you can save them for future needs. However, keep in mind that an EPDM liquid product is only going to be good for about a year. After that, the formula begins to separate and cannot be remixed. It’s best to buy only what you need and pick up repair kits or small containers of liquid EPDM for any repair or maintenance needs.

The Pros and Cons of Liquid Roof Coatings

Liquid roof coatings, also known as EPDM roofing or EPDM coatings, are a synthetic rubber roofing compound designed specifically for flat or low-slope roofs like those found in RVs and mobile homes. Although rubber roofing is also used on residential and commercial buildings, the available materials for RVs are usually quite different than the materials sold for building use. By getting to know this material, you can better understand whether or not it is the best choice for your RV roof.

The Advantages of EPDM Liquid Roofing

One of the biggest benefits of liquid roof coatings is the cost. Like rubber sheeting, liquid roof products are a fraction of the cost when compared to other non-porous or rigid roofing materials. It is also a really simple product to install or apply, so you can do the work yourself if you want. Even if you hire someone, you can trust that you will pay much less for labor because the job will go much quicker than other types of roof installation.

Liquid EPDM dries lightweight, which is another reason it works well on RVs. No additional reinforcement is needed, and you don’t have to worry about how much weight the roof is adding to your ride. The finished, cured rubber doesn’t scratch easily and can stand up to extreme temperatures and plenty of climates. Plus, when repairs are necessary, they are easy with caulking sealant and sealant tapes that are designed to work with your EPDM roof.

One of the first questions or concerns raised about rubber roofing is fairly obvious when it comes to RVs: rubber is black, so won’t it absorb heat? Yes, if you choose a product that dries black, your roof will absorb heat and cost more to cool in the summer months. However, many liquid EPDM products are being made with an added oxidizer that turns the rubber white with air exposure. This creates an even stronger layer of protection and a reflective surface that will repel heat rather than absorbing it.

The Disadvantages of EPDM Roofing

Liquid roof coatings don’t really have a lot of drawbacks. Some people don’t like the way that these roofs look when finished, but today’s products actually create a lot better look than you might think. Also, as mentioned above, black rubber roofing will absorb heat. The solution to this, however, is easy. White liquid roofing is available, as are products that will dry white.

How to Choose Your Roofing Material

Now that you know more about EPDM liquid roof coatings, you can make a more informed decision for your RV’s new roof. Use the advantages and disadvantages discussed here to help in your decision. Other factors that should be a part of your choice of new RV roofing include:

  • Personal taste or preference (if you have one)
  • Longevity
  • Maintenance and upkeep
  • Manufacturer’s recommendations for your specific RV (if any)

Ultimately, the decision is yours to make. However, by taking the time to compare your options and see all the benefits of liquid roof coatings, you might realize it is exactly what you need.

The Bottom Line

EPDM liquid roofing has been around for years, and for good reason. It is a cost-effective, easy-to-use material that anyone can apply. It provides full protection and requires much less maintenance and upkeep than other roofing materials. There are so many different styles of liquid roofing that there should be a product for just about every need. As an added bonus, many products are made of recycled materials, so you can feel good about your impact on the environment, too.

Most RV owners want to know one thing when choosing a roof: which are the best RV roof coatings, and why? There are a number of different products on the market today, which can seem intimidating to even the most seasoned RV owner. However, each has its place and purpose. You can learn a lot about the best products by looking at the leading brands and what they offer for coatings, sealants, and other roofing products and supplies.

Although no two brands are the same, the best RV roof coatings do have similar features that make them stand out among the rest. Here are a few things to keep in mind when you are looking for the best coating for your RV roof:

  • Multi-use Option: Although there are material-specific products on the market, coatings that are designed for use with multiple materials will typically give you the most universal uses. The best products don’t become the best by only serving one market, after all. Whether or not you choose a product that can be used on various materials, this is one factor that helps products rank higher.
  • Roofing-safe Ingredients: Despite the fact that substances like citric acids and petroleum oils can be damaging to rubber roofs, some products that contain them claim to be “safe and effective” as an RV protectant, sealant, or roof coating. Make sure that you know what products are safe for your roofing surface and stick to those coatings.
  • Protective Features: The best RV roof coatings have the most protection features to offer. They should offer protection from standard things like water damage and leaks, as well as UV rays, extreme temperatures, and other elements. The more protection a roof coating offers, the better investment it will be.
  • Affordable Pricing: Although people are willing to pay for quality, the best RV roof coatings won’t make you spend a fortune. They will provide a versatile, effective coating solution that is reasonably priced. Plus, DIY products are growing in popularity so the increasing demand for competitive pricing is only going to continue to save you money.
  • Convenience and Ease of Application: For the DIYer, convenience is a must in all projects and products. The top 10 brands of RV roof coatings on the market today all offer exactly that: a simple, convenient application that doesn’t take a lot of time and effort.
  • Self-Leveling: Although application with a mop or cloth is usually effective at relatively even distribution, it doesn’t always work. Choosing a sealant or coating that self-levels as it dries allows you to avoid pooling, which can lead to worsening damage or leaks down the road. It isn’t necessarily a must-have, but when you are coating an entire roof, or even a large part of it, the self-leveling feature is convenient and provides peace of mind.

According to many RV websites and communities online, the brands that have the best RV roof coatings include:

  1. Heng’s
  2. Dicor
  3. Proguard
  4. Rubberseal
  5. Flex Seal
  6. Kool Seal

However, each brand has its own features and pros and cons to consider. Use the tips provided here to help you find the best roof coatings for your RV, no matter what you have in mind. When chosen carefully, your RV roof coating can provide years of protection from water, weather, heat, UV rays, and other extreme elements. This product essentially works as an all-season protector, keeping your roof looking and working like new despite the elements. For those who travel often and lack covered storage in extreme weather, a roof coating might be the only way to protect their RV roof for the long haul.

Are You Suddenly Finding Yourself in Need of a Camper Top Coating?

It’s not how you planned on spending your tax return, but when your brother-in-law told you that his friend’s, wife’s, cousin had a used camper for sale; you just couldn’t turn it down. When you got it home, you took a closer look at your new baby, and that’s when you noticed that the roof was looking a little rough. Alright, don’t panic, you can handle this.

Assess the Condition

The first step is to carefully assess the condition of the camper roof. If you decide to go up on the roof, please be very careful! Are you are able to see any cracks or leaks? Be sure to check around the roof vents and along the roof edges. You’re probably going to see a lot of dirt and mildew stains, but that’s pretty normal. Alright, you decide that it would be a really good idea to start the camping season with a new look and a little peace-of-mind. It’s time to think about a camper top coating.

Choosing the Right Camper Top Coating

Chances are the roof of your camper is either metal, fiberglass or EDPM, which is a synthetic rubber surface. There are cheap ways to coat camper roofs, like water-proof paints for metal or fiberglass surfaces, but ordinary paints will chip and crack. Camper top coating isn’t something that you want to do often, so it just makes good sense to use products that are specifically designed for the job. One of the better choices is a liquid rubber coating, because it can be used effectively on most camper and RV roof surfaces.

Preparing the Roof’s Surface

No matter what type of camper top coating you choose, properly preparing the roof’s surface needs to be your first step. The roofs of campers and RVs are constantly exposed to absolutely everything that Mother Nature can throw at them; wind, dust, dirt, rain, snow and harsh sun. All dirt and mildew needs to be removed to ensure that the new coating will adhere properly. Start by sweeping or blowing any loose debris off of the roof. Next, you’ll need to thoroughly clean the surface. Be sure to check the caulking around the roof vents and replace as necessary.

Deciding on a Liquid Camper Top Coating

You’ve decided to use a liquid rubber roof coating because they are the most flexible and long-lasting. Which one do you choose? Time becomes a big factor in making the decision. You’ll need time for cleaning the roof, repairing any caulking, sealing the edges with butyl rubber tape and applying the coating. Some brands of liquid camper top coating require two coats, so choosing one that only needs a single coat will save you hours of time. If you’re doing the work yourself on a weekend, and perhaps are concerned about rain, every hour counts.

Sizing Up the Situation

Resurfacing your camper or RV roof is a good idea if it’s older and showing signs of wear. If you choose a liquid rubber camper top coating, you’ll get a surface that looks new and will last for many years. You can do the work yourself, but if you don’t feel comfortable with that, you should hire a professional. It shouldn’t be too expensive because the surface area is relatively small. If you buy the camper top coating yourself, you can shop around for the best price and further reduce the cost of hiring a roofer. Most of all, resurfacing the camper roof will give you years of worry-free camping.

Why Buy a Roof Coating for RVs?

You deal with a lot of stress every day. It may come from the job, bills, children, parents, health issues or a hundred other things. That’s one of the main reasons that you bought your RV, to get away from it all. Packing up the RV and taking it on the road is one of the greatest joys in your life. You get a chance to visit new places, meet new people and most importantly, rest and relax. Your coach is your home away from home, so you want it to be clean, comfortable and trouble-free. You won’t be able to relax, if everywhere you look, there are constant reminders of all of the things that need to be repaired. Keeping your trailer well-maintained and in good condition goes a long way toward giving you that peace-of-mind that you’re looking for. The single biggest factor that decides if your RV will stay in good shape is the condition of its roof. Damage to the integrity of the RV roof will translate into damage throughout the whole structure. That’s why it’s so important to regularly inspect and maintain your roof, and if it does need to be resealed, to use a roof coating for RVs.

A Roof Coating for RVs is Different.

Every roof needs to be repaired at some point. Consider for a moment all of the stress that every roof must endure: rain, hail, sleet, snow, wind and harsh sun. RV roofs are subjected to all of those things plus one more that is unique to them, movement. You may not have considered it before, but while you’re driving down the road, the structure of your RV is always moving, pitching and swaying. That’s why it’s important to use a roof coating for RVs. These days, most people use a liquid roof coating that’s made from EPDM, a synthetic rubber, because it remains flexible when dry and can withstand movement without sustaining damage.

Other Benefits of a Roof Coating for RVs

A roof coating for RVs that is made from liquid EPDM protects your coach from more than just the stress of movement. Your RV roof is much lighter than the roof of a house for obvious reasons, so it has a tougher time insulating the interior of the coach from heat and cold. A high quality EPDM liquid roof sealant resists the sun’s harsh ultraviolet rays as well as extremes in temperature, helping you stay cooler in the summer and warmer in the winter.

Choosing a Roof Coating for RVs

After performing a thorough inspection of your RV, you’ve found some defects that need to be addressed. You’ll want to choose a roof coating for RVs that is of a high quality and is both easy to apply and cost effective. If you have had to resurface your coach roof before, you know that there’s more than a monetary cost involved. To do the job right requires hours of prep work; the amount of time depending of course upon what work needs to be done. Most sealant brands also require that the work be completed when the weather is fair. Taking all of that into consideration, the last thing that you want is to have to apply a coat of sealer, wait hours for it to dry then have to apply a second coat. You’ll save a lot of time and money if you buy a roof coating for RVs that’s made from genuine EPDM and that covers well in only one coat. Now you can relax and enjoy your leisure time.

Why You Want to Use Liquid Roof Repair Coatings

If you own your RV long enough, it’s almost certain that you are eventually going to have to make repairs to the roof. Regular inspections can help lessen the frequency and severity of repairs, but there is no accounting for accidental damage. The sooner defects and damage are addressed, the easier and less expensive they are to fix. The final step in repairing RV roof damage is to coat the area with one of the many available liquid roof repair coatings.

The Advantages of Liquid Roof Repair Coatings

Liquid Roof Coatings

EPDM rubber has always been a favorite RV roofing material for a number of reasons. A rubber roofing material is better able to withstand the stress of constant movement that RVs are subjected to. Also, EPDM rubber roofs are less susceptible to extremes in temperature thus helping to insulate your coach and keeping you warmer in winter and cooler in summer. In the days before the development of liquid EPDM rubber, this type of coating could only be applied in sheets, which worked well until it became necessary to repair or replace part of the surface. Covering a repair area with a sheet of rubber was difficult at best because one was always left with the problem of what to do with the seam. Products like caulks and putties came out that attempted to address the problem, but nothing really seemed to do the trick. That all changed when liquid roof repair coatings made from EPDM rubber came on the scene. Now, because a liquid could quickly and easily conform to any shape, even a raised surface, it was finally possible to get a long-lasting seal on any repair.

Things to Consider When Using Liquid Roof Repair Coatings

All liquid roof repair coatings are not created equal, so what do they have in common? Liquid EPDM roof coatings will only adhere to surfaces that are clean, dry and free of any film or dust. Getting an area repaired and in that kind of condition takes time. The good news is liquid roof repair coatings are easy to apply. It’s pretty much the same as any other type of painting. That’s where the similarities between brands end. Because properly repairing an RV roof is labor and time intensive, you don’t want to spend any more time than is necessary getting the job done. Some liquid roof repair coatings require you to apply two coats in order to get a lasting finish. That doesn’t make any sense. First of all, if they can’t do the job in one coat, what assurance do you have that it will be done properly in two coats? Second, by requiring a second coat, they’ve added hours of drying time to the job. There is a product out there that provides a long-lasting finish in just one coat, saving you a lot of money and hours of time. If you went to the hardware store to buy interior paint for your house, which one would you buy; the one that takes two coats to cover, or the one that covers well in just one coat?

Tips for Using Liquid Roof Repair Coatings

If you are doing the repairs on the roof yourself, take some time while you’re up there to thoroughly inspect the whole roof, not just the obvious areas. Check around the base of the vents, antennae, air conditioning unit and around the roof’s edges. If you’ve taken the time to go up on the roof, it just makes good sense to be certain that you’ve accounted for everything.

Keeping your RV in great shape is important if you want it to last for a long time. RVs are not cheap vehicles, so you need to provide the proper care and maintenance to ensure it stays in perfect order. This means more than just taking care of the oil and the engine maintenance, and it means more than buying new tires. You also have to think about what is over your head. Namely, the roof. The RV helps to keep you out of the rain and weather, which is something that many people end up taking for granted. It is only when they start to notice problems with leaking that they ever even consider their roof.

Before You Notice a Leak

Even if you do not have any leaks in your roof right now, that does not mean that your roof is safe. You should still take preventative measures to make sure that a leak doesn’t happen. This is true even if you have an RV that is relatively new. Using a permanent RV roof coating, such as RV Liquid Roof, will help to provide your vehicle with the added protection it needs. This type of coating helps to add protection that is needed for a vehicle like an RV, whereas typical roof coatings won’t. When it is applied correctly, it has the potential to last for decades.

By adding this coating before there is a problem with your roof, it means you will not have to worry about a leak. This is the type of peace of mind that anyone can get behind.

When You Already Have a Leak

Of course, not everyone is fortunate enough to have added the RV roof waterproofing coat before they noticed an issue. If you have already found a leak in your roof, it might not be too late. There are still options for you. The first thing you need to do is check to see where the leak might be coming from. There could be just one location, but you should examine the entire roof to see if there are multiple breaches that could allow water to get into the vehicle. Always be sure to check around the venting and other areas, as well, since these can be prone to problems, particularly with older RVs.

Once you have located the areas of the leaks, you can then clean the roof and apply the patches to help cover them up. However, you don’t want to stop there. You still want to use the RV Liquid Roof so that you can add that layer of coating to the top. Once you do this, it should stop any future leaks from occurring.

If you caught the problem before it caused serious damage, you should be fine. However, if the problem has been happening for a while, there may be deeper damage in the RV, or even mold growth, which you will need to address.

It Is Easy to Apply

One of the biggest benefits of this type of RV roof waterproofing is that it is easy for you to do, and you do not need to hire a professional. All you need to do is make sure you have the right tools and the right permanent RV roof coating. Follow the manufacturer’s instructions to be sure that you apply it properly. Essentially, all you will need to do is make sure the roof is clean, patched if needed, and then you can apply. It will go on easily, just like paint, and it only takes a short time to coat your entire RV roof. It is one of the best investments you can make.

With just a little work, you can keep your RV in great shape from top to bottom so you and your family can enjoy it for many more years to come. Make sure it gets oil changes as needed and that you have it checked out by a mechanic at least once per year. Be sure to add new tires as your old ones start to wear out, as well. Additionally, you must make sure that you are giving your roof the attention it deserves. Many people never think about the roof until it is too late and they have a leak.

By using RV Liquid Roof coating now, you can alleviate these problems before they start. Let’s look at some of the best reasons to start using this type of coating on your RV roof today.

RV Liquid Roof Coating

Adds Longevity to the Roof

Just as with any type of roof, the RV roof is exposed to the elements, which means eventually, it will start to break down. Fortunately, with RV Liquid Roof coating, it is possible to lengthen the life of your roof substantially. When it is properly applied, it can provide protection for your roof for up to 20 years, ensuring that you will have less to worry about when you are heading out and trying to enjoy your vacations.

Works With Environmental Changes

Think about all of the things that can damage a roof. It deals with the wind and the rain, along with the sun and possibly snow depending on where you live. Even changes in the temperature can cause issues with the RV roof. Eventually, it will become brittle, and that is when leaks and similar issues start to occur. Using Liquid Roof for RVs will help to provide a protective layer between the roof and those elements. It stands up well to all manner of weather, as well as to UV rays. It is flexible, too, which means even if the roof expands and contracts during temperature changes, you do not have to worry about the coating cracking.

Easy to Apply

These coatings are simple to apply, even if you have little to no experience. Once you clean the roof and add any patches, if needed, you can apply it to the roof just like you would paint. It goes on easily, but you do need to make sure that you have a smooth and even coat. Fortunately, the formulation tends to make this easy. Even with a relatively large RV roof, this should not take you more than a couple of hours. It only needs to have a single coat, so you will be finished even sooner than you imagine.

Once it is on, it will begin providing protection immediately. It should cure in about a day or two. Ideally, you will have sunny and dry weather when it cures, as this will help the process move along faster.

The RV Liquid roof coating will provide protection for years to come, and you will find that it makes maintaining the roof easy. Just keep it clean of debris and check it occasionally for signs of damage from falling debris and the like, and it should be good to go.

It Is an Affordable Option

Finally, when you use RV Liquid Roof coating on your RV, it can help you to save a lot of money. Consider just how much money it would cost to make repairs to the roof, or repairs to water damage that occur because of a leak.

If you want to take care of your RV as best you can, adding one of these coatings is an ideal choice.

6 Benefits of Using Cool Roof Coatings on Your RV

If you own an RV, then you are among the privileged few who are lucky enough to have the means to travel across this great nation without having to stay in a hotel or motel every night. You can visit national parks, local campgrounds, beaches and more, and do it all in the comfort of your own home on wheels. Of course, you need to care for your RV, and that means using the right material to reseal your roof periodically. Cool roof coatings offer some important benefits that make these the go-to solution for many RV owners. What benefits might you see?

1. Keeping Your Cool

Perhaps the most significant benefit of cool roof coatings can be found in the name. They help keep your RV cooler. For anyone who has ever traveled during the summer in an area of the country where temperatures climb pretty high, that benefit cannot be overstated. You’ll find that the interior of your RV maintains a more consistent, lower temperature without the A/C cycling constantly.

2. Reducing Energy Consumption

Another important benefit with cool roof coatings is that they can help you reduce your energy consumption. Sure, you’ll still need to run the air conditioner while you’re on the road, but once you park and connect to the host location’s power, you start relying on the local power grid to keep you cool. Yes, you pay for that with your lot rent or overnight fees, but responsible RV owners understand the importance of being able to reduce their overall energy consumption regardless.

3. A Longer Lasting Roof

It might seem odd to think that cool roof coatings can lead to a longer-lasting roof, but it’s true. Compare a roof coating formulated to reflect as much heat and sunlight with one that does not, and you’ll see that darker, more absorbent roof coatings oxidize more quickly, and are subject to a lot more wear and tear. You’ll replace the coating much more frequently with a product that is not formulated to reflect sunlight.

4. Less Wear on Internal Structures

While you need to be concerned about the lifespan of your roof coating itself, you cannot forget about the underlying structures. More heat absorbed by the roof material means more heat absorbed by internal structures. That equates to more thermal expansion, which leads to more wear and tear. With cool roof coatings, you do not need to worry as much about that wear and tear.

5. You’re More Comfortable

With a roof coating designed to reduce sunlight absorption and heat retention, you also get to stay more comfortable in your RV for longer periods. In fact, if you’re traveling in the mid to northern latitudes, you may be quite comfortable overnight without running the air conditioner at all. There’s a lot to be said for keeping your cool for longer periods, including the fact that you’ll get longer, more comfortable periods of sleep, which is something that we could all use.

6. Reduce Maintenance Costs

Finally, you will find that cool roof coatings can help you reduce your overall maintenance costs. Yes, you will still need to reapply your rubber roofing from time to time, but that need will be less frequent. Substructure deterioration is slowed, and because you’re running your air conditioner less, you experience less wear and tear on A/C system components, too. The overall result is a reduction in the costs of maintaining your RV.

As you can see, there are some very important benefits to be found with the right RV roof option. RV Liquid Roof offers a long-lived solution that helps you keep your cool.

How to Apply Liquid EPDM Coatings to Your RV Roof

Even a modest RV is an expensive asset, and one that can bring you and your family years of joy and excitement. Whether you use it for summer vacations, or you spend a lot more time in it, you know the importance of regular care and maintenance. Roof sealing is vital part of that, and rubber roofs are the most common on the market, which makes it important that you know how to liquid EPDM to revitalize and seal your roof. Thankfully, there’s not really that many steps. We’ll discuss what you need to know below.

Get Your Tools

First and foremost, you’ll need to get your tools together. You’ll need a squeegee, paint roller and roller refills, as well as a long handle so that you can apply liquid EPDM to more areas without having to bend too much. You will also need something in which to mix the sealant, as well as a putty knife, a box cotter, a paintbrush or two, and some spare rags for cleanup.

Liquid EPDM Coatings

Prep the Roof First

Once you’ve gotten your tools and supplies together, you’ll need to prepare your RV’s roof. Really, this just means giving it a good cleaning. However, make sure that you do this thoroughly. Any dirt or debris left will compromise the seal of the liquid EPDM, and may lead to premature failure and leaks. Scour the roof and then rinse it thoroughly. Let it dry completely before you apply any liquid rubber.

Mix It Up

Once you’ve cleaned the roof and allowed it to dry, you need to mix the liquid EPDM with the catalyst. In most cases, you can do this in the bucket the product came in, but you may need to use another container. A power drill will be your best friend here – a 3/8” drill is ideal for small quantities, but you’ll need a 1/2” drill for larger volumes. Mix the material very well.

Application

Now it’s time to start applying the liquid EPDM to the roof of your RV. Tape off areas that will not need to be resealed first. Use the roller and a long handle and pour an amount of EPDM directly onto the roof itself. Spread that out with the squeegee in a thin layer. Once you have thinned it out, use the roller to spread it around the roof evenly. If you notice that roller marks are left behind, don’t worry. This material is self-leveling, and those marks will disappear eventually. The most important thing is to make sure that you are applying enough liquid EPDM for the space.

Start at the front of the RV, and work toward the rear, where your ladder should be located. Take your time, and make sure that you apply the material evenly in all areas. Work in small patches is necessary, and use your paintbrush to apply EPDM in areas where the roller cannot reach, such as around vents and flashing.

Allow Time for Curing

Once you have applied a coat of EPDM to the entire roof, you’ll need to let it cure. Note that it is waterproof immediately, so even if it rains as soon as you finish applying the material, it will not harm it. However, it does require time to fully cure. This will vary depending on the ambient temperature and humidity level. Colder temperatures and higher humidity will lead to longer curing times. However, you do not need to worry about uncontrolled curing rates or the development of porousness.

There you have it – applying liquid EPDM is simple and fast, and provides effective protection for your RV’s roof.
