Have you discovered a water leak in your RV’s roof? If so, Liquid Roof repair coatings can help you repair the issue and protect your investment. RV roofs are subject to a lot of stress, as well as sheering forces, and wear and tear. All RV roofs will eventually develop leaks, so even if you have not experienced one yet, there is still the potential. This makes knowing how to use repair coatings effectively important. Below, we’ll discuss some of the most important tips.
Check the Weather
You should apply Liquid Roof repair coatings when the weather is warm and sunny. Ideally, no rain will be in the forecast for a couple of days. However, if it does sprinkle on you, don’t worry. The material is waterproof immediately.
Use the Right Cleaning Tools
You need to make sure to completely clean the roof of your RV before applying Liquid Roof. You’ll need a few 3M Scotch Brite pads to remove dirt, dust, debris, mildew and other things that might prevent proper adhesion.
Apply Just One Coat
Liquid Roof repair coatings should be applied in just one layer. This can be up to 35 mil thick. There is usually no need for more than one coat.
Let It Cure
Like all other liquid rubber repair products, Liquid Roof will need time to cure. It is dry to the touch in just a few of hours. However, it may take up to 30 hours to dry to the point that it can be walked on. Full curing can take up to seven days.
Check the Condition of the Existing Roof First
Liquid Roof is strong, durable, waterproof and flexible. However, understand that many of its characteristics will vary depending on the condition of the roof onto which it is applied. So, if the existing roof of your RV is in bad condition, then Liquid Roof may not last as long or create as good a seal as would otherwise be the case.
Surface Condition Matters
Note that smooth surfaces are not ideal for adhesion with Liquid Roof repair coatings. The best surface is rough, and/or porous. For instance, wood and cement offer excellent adhesion. However, smooth plastic may need to be primed to ensure that the surface will offer good adhesion.
Check the Amount Needed
A single gallon of Liquid Roof can cover up to 200 square feet. So, you will need relatively little in order to cover the entire roof of your RV. With that being said, buying too much is often unwise, as there is a definite lifespan to material left in the original bucket. Always make sure to carefully calculate the amount needed to cover the entire roof, and then buy as close to that amount as possible.
No Need to Prime
While TPO and other very smooth surfaces will need primer in order for Liquid Roof repair coatings to adhere properly, this is not the case with most surfaces. There is no need to prime rubber roofs, or any other surface with enough surface roughness for adhesion. However, note that if you have used a different type of coating over your original EPDM roof, a coating of primer may be necessary. The same thing applies to surfaces that have degraded significantly due to weathering and aging.
Liquid Roof repair coatings offer a fast, effective way to recoat your RV’s roof, repair leaks, and revitalize older EPDM roofs. By following the tips above, you will have an easier time with application and avoid some potential pitfalls.
