Proper Application Procedures for Liquid RV Roof®

Liquid Roof is ONLY for Recreational Vehicles, Mobilehomes and Trailers

Proper Preparation Prior to Application

liquid roof

We always suggest starting out with an inspection of your roof. Look at the existing seams of your roof and if you notice any separation of the seams you will want to get our two sided butyl tape and lay that down in the middle of any of the seams before applying the Liquid Roof. Next go around the perimeter of the roof and around your vents and see if there is any loose caulk. Any loose caulk needs to be removed and replaced with either a butyl or an acrylic caulk. Any silicone caulking that is currently on the roof needs to be removed. When cleaning or washing your roof the important thing you are looking for is that your roof is free from any dirt that could be picked up during the application with the roller. Finally be sure that all fasteners, screws etc. are tightened. Remove any loose rust with a wire brush. You will not need to apply a rust inhibitor on mild to medium rust; in fact once the Liquid Roof is applied it stops the oxodization process on contact. If you know the entire history of your roof great; however, if you are a 2nd or even a 3rd owner you may not know what other products were put on the roof over its lifetime. In these instances we highly suggest priming those roofs with the ProFlex primer. This insures an acceptable substrate for the Liquid Roof. A note regarding Fleetwoods; majority of Fleetwood units are made with Alpha rubber roofs and will also need the ProFlex bonding primer.

For those that have a roof that requires the primer you also have the option to use our Rvroofmagic which does not need a primer regardless of the type of roof so you save $170.00 dollars. You can visit our other product we manufacturer at: https://www.rvroofmagic.com

A word about chalking. If you get up on your roof and wipe your hands and get a chalk residue that is simply a normal wear of an EPDM roof. Once your roof begins to chalk you will not be able to remove all the chalking layers so don't even try. The good news is that the Liquid EPDM is manfactured differently and will not chalk after 8 or 9 years like the sheet EPDM does.

It is important that the surface be perfectly dry prior to the application. Many of our customers ask us if a power wash is necessary. If you have access to a powerwash, that would be the easiest method. You want to be careful of course not to use a tip that will cut through your existing epdm roof. If you do not have access to a powerwash then a mild detergent and a soft bristle brush will do the trick. Regarding detergents our customers like Simple Green andFabuloso. We can't stress this enough; the surface you are coating needs to be perfectly dry. That means if you get up in the morning and there is a light dew on your roof you need to wait until that is burns off to begin your application. You should also have a couple 3/8 inch rollers your squeegee on a broom handle, rags, you drill mixer and some mineral spirits or Xylene just in case you get some on an area of the RV you did not want to coat. The coverage on a gallon is appriximately 42 square feet. This will result in a a thickness of approximately 20 mil; about the depth of 5 pieces of paper. You do not want to spread it out any further as it would void the warranty. If you have any doubts about the mil coverage we suggest simply visiting a paint store and purchasing a mil guage. It is a metal circle that has notches cut out that allows you to dip it into any wet material and read the mil. They are under $2.50

Mixing the Material

liquid roof application directionYou will notice when you get your product the can is somewhat under filled, this extra room will allow for you to mix the catalyst without having to pour the material out in another container. You can watch a mixing video here We suggest mixing the material first without putting in the catalyst for approximately 1 minute then pour in the catalyst and mix for an additional 4 minutes. Once the catalyst is added you have four hours to use the material before it begins its initial set up.
