When RV owners don’t take roof coating seriously and keep the roof in a bare condition for years, the roof starts to leak. It stays unnoticed until the owner feels uncomfortable inside the RV.

The sealant can cover about 100 sq. ft. per coat. If you want to achieve a 40 to 60 mil membrane, you need to apply 2 to 3 heavy coats — most 30 ft. RV would require 1.5 pails or sealant to be able to cover the roof appropriately.

Liquid rubber sealant is easy to apply, very similar to painting. You can use brush, roller, or paint sprayer to apply it to the root. If you choose to use a paint sprayer, make sure it’s of high quality. It would require heavy coats to build up the waterproof membrane successfully.

If you want to apply more than one coat, you need to allow the first coat to dry. It would take roughly about 24 hours, depending on how rough the surface is. When you apply the sealant, make sure there is no intense sunlight in the area.

Also, if there is any leftover material in the container, you can close the pail and use it later if necessary.

Other than sealing, if waterproofing and UV ray resistant is your concern, it will not let you down. The sealant can outstand heavy rain as well as snowfall.

The coating should have water-resistant properties to repel water off the roof. If there is rainfall or snowfall during the camping, the water-resistant coating will make sure it does no damage the roof by repelling the water off it.

Importance of Taking Care of Your RV’s Roof

The very first thing before you apply the coating is to check the condition of the roof and clean it if necessary. You need to be very careful while doing this as not all RV roofs are suitable for walking.

Roofs that are made of different materials require different cleaning agents. It’s always recommended to check the user’s manual to know which cleaning soap or agent works best for the roof material.

Don’t use citric-based acids, petroleum solvents, and harsh abrasives-based cleaning agents on a rubber roof.

The normal cleaning procedure is to spray on the roof using clean water to clean dirt and dust from the surface. Then, apply cleaning soap or agent and gently scrub around the surface with a circular motion. You can use cloth, bristle brush, sponge, or non-abrasive material.

Afterward, rinse the roof with clean water to prevent residue build-up on the roof and sidewalls.

You can gently rinse the sides as well. But, be careful about the decals or paint, and be sure not to leave soapy streaks on it as well.
