Liquid roof painting is becoming a popular choice for RV roofing, thanks to its durability, economical pricing, and versatile application. Plus, most liquid roofing products can be installed even by a novice, making them preferable to roofing materials like fiberglass or vinyl that may require a professional touch. If you have opted for a liquid roof for your RV, you will be happy to know that the application process is fairly simple.
Step One: Measure and Inspect Your Roof
The first thing that you need to do, once you’ve decided that you are going to use liquid roofing products, is to measure the roof space to see how much product you will need. Typically, a gallon of liquid roof paint roofing will cover 40-45 square feet. If you already know the dimensions of your roof, you can calculate the area rather than going topside to measure it by hand.
For example, if your RV roof measures 9.5 feet wide and 26 feet long, your total coverage area would be 247 square feet. This would require about six or seven gallons of liquid roofing.
Step Two: Choose Your Materials
Now that you know how much liquid roofing you need to buy, you can begin shopping for the product that you will use. EPDM liquid roof is a common product and it is available from all of the major brands in the RV maintenance and repair industry. Liquid roofing is generally sold in single gallon containers or 4-5 gallon buckets. Prices can range from as little as $50 for a gallon of liquid roofing material to more than $400 for a five-gallon bucket of high-end liquid roofing.
The variety of products can get confusing for some people, but you can buy this liquid roofing paint like you would anything else: find the products that fit your needs and your budget. The good news is that EPDM liquid roofing is generally compatible with all types of existing roofing surfaces and material, including vinyl, fiberglass, fabric, metal, wood, and existing rubber roofing.
Step Three: Clean and Prep the Roof Surface
One of the most important steps in the process of applying a liquid roof to your RV is cleaning and preparing the existing surface. The last thing that you want is to invest money in a new roof, only to have the application ruined or less effective because it didn’t adhere to the surface correctly. Remove all of the obvious debris and use a broom to sweep the roof thoroughly.
Important tip: Never use citric cleaners or petroleum-based products on an existing rubber roof because those can be damaging to the roofing materials.
Once you have removed all of the dirt and debris, use a cleaner and primer that is specifically designed for your existing RV roof. While you’re washing and rinsing the roof, you can inspect for damages, cracks, or other areas that may need to be addressed before applying the new liquid roofing paint material.
Step Four: Apply Liquid Roof Paint Roofing
Application is one of the easiest parts of the process of replacing your RV roof when you choose a liquid roof paint roofing product. You can simply pour the liquid onto your RV’s roof and then use a squeegee or brush to spread it around. A small brush is useful for ensuring a proper coating around the fixtures on top of your RV. For best results, start at one end of the RV and work your way back, so that you don’t have to walk on the newly applied rubber paint. Liquid roofing will be dry to the touch in about three or four hours and will cure completely within 24 hours of application.
