Liquid Rubber RV Roof Sealant- Professional-Grade Solar Reflective Flexible Waterproof Membrane Coating for EPDM, TPO, Fiberglass & Aluminum Camper & Travel Trailers- Brilliant White, 1 Gallon

After reading the recommended coverage, it was clear that I needed approx. 5 gallons to cover my 20’ enclosed trailer. Although it was a bit more expensive, am so glad that I purchased five - one gallon pails instead or a single 5 gallon bucket for the following reasons: 1) Managing a few single gallon pails at a time - up a ladder and on top of the trailer is a lot easier than one 5 gallon bucket. 2) I quickly realized that this product is very “runny” and liquid. This is a GOOD attribute as it will flow into smaller gaps and similar leak- prone areas. A single gallon covered my 20’ X 8’ trailer nicely by using a 3/8 nap roller. 3) This allowed me to apply four other successive coats on top of the first one, each time going in a different direction ( east/west - north/south ). This does require more time than a single “heavy” application, however by applying in this fashion, I am very comfortable that I have left no opportunity for any missed areas that would result in a leak. I am glad that I took the time to use generous amounts of blue painters tape to mask the edges of my trailer roof, as this product is very fluid and can easily find its way outside of the area that you are focusing on. However, after several applications and a good “build up”, I realized the need to cut the entire edge of my tape before pulling off my tape due to the extreme elasticity of this coating, this ensured a good seal to my roof and that I would not tear it away when I removed my tape. THIS FINAL STEP IS VITAL AND SHOULD NOT BE OVERLOOKED. I am very confident that five individual applicants of single gallons in opposite ways will result in a superior coating and is by far much easier to manage than a single five gallon bucket. Simply purchase five paint rollers and toss each one at a time. Cleanup is easy each time with water.

Had a small leak on a flat aluminum travel trailer roof which required removing the ceiling and insulation inside to find it. Could not find it from the roof but after removing the ceiling and insulation, where it leaked, could see five small pin holes from the sun shining in from them. After reading reviews for these type of products to be used as a water sealant, decided on this brand for price, ease of application and discovered it spreads so smoothly was able to do three applications for an area that the container said would do only one application. There is a huge benefit to multiple thin applications versus one and some draw backs but multiple has the advantage of being more durable. Which I inadvertently had to test since the drainage pattern from the condensation from the air conditioner had changed, needed to lower a dam so used a hammer to lower it. Fully expected the material to pull away from the surface after the pounding but it remained adhered to the roof surface, which could have something to do with the primer too but nice to know it can take a beating and not flack. But the real surprise, and still find unbelievable, is the aluminum temperature on the underside (have not put insulation or ceiling material back) measures, using my Etekcity Infrared Thermometer, as the same temperature as the thermometer in the shade, when the roof is in full sun This aluminum roof without the product and only an inside reading at the ceiling, BEFORE, with insulation in between it measured 10 degrees hotter. Also took a couple measurements before while the ceiling was open with just bare underside of the aluminum in full sun on a cool spring day showed the underside of the aluminum was 100 degrees, while outside temperatures were 65 degrees. The bare aluminum is gathering heat and conducting it Here is the part which is unbelievable, and could be a good thing or a bad thing, depending on winter or summer, measured the temperature of the roof in the evening after the sun has gone down, air temperature was 64 degrees, the roof temperature with this product, no sun light on it, showed all surface area measured 6 to 8 degrees COOLER than the surrounding air. It does not absorb the heat and radiates it back. I do not know all the science involved only know what I measured, and expecting a substantial savings in air conditioning cost This is the only product of this type have any knowledge but if they all work like this one everyone needs to put it on their roof, just know this one seems to be a miracle product, so highly recommend it.

Very thick white. Applies easy with roller. Keep in mind do not use if the humidity is close to 80% apply late morning through mid afternoon so it has at least 2 hours to dry. Applied to my 30' 5th wheel RV roof 5 gallon think I will get 6 plus coats. Cleans with water hose and sprayer. The primer applied and was ready to apply the sealer within 2 hours. The cleaner was ok but the room was old and had to use a 2nd bottle of cleaner.

I looked for quite some time and read reviews trying to find the best sealer. This was a little bit more expensive than the other one that I was looking at but I am extremely happy with this sealer I did my RV with it and I also had leftover so I did my dad's pole building roof where the screws attached because it was leaking and I also did ours only where the screws attached and we have not had one week in either pole building nor one week in the RV the RV was just maintenance we never had a leak in the RV but it was time to redo it and it came out beautiful I highly recommend this product and I highly recommend the primer to put on before this product I used both and I am very satisfied.

We have an old houseboat that has a classic houseboat, open roof (white like a standard rental houseboat). It has been coated with so many sealants over the years that it is hard to determine what the surface actually consists of. Unfortunately, years of the roof exposed to rain and sun, combined with misc. damage and/or small cracks have created a problem and the roof leaks during rain. We have tried a variety of methods to seal the roof including rubberized tape, caulking-like paste, etc. Found this product and wanted to try it because it has a "two part" application process (primer then sealant). Applied the primer as instructed and followed recommended drying/coating times. Product was very sticky as it cures. So sticky that if you step on it with your shoe it will stick so much that you can pull your foot out of your shoe. Applied the sealant on top of the primer after waiting the recommended drying time (two coats of primer and two coats of sealant). Of course we scrubbed the surface clean before did the application and the application was completed during the heat of the day (+90F). No rain came for several weeks and oddly the surface stayed sticky/tacky. It seemed like maybe it would never completely cure. Fast forward two months and the surface finally cured (no longer tacky). We are now seeing record setting rain fall in Northern California (and snow) and we do not have one leak (we have never had a winter season where the roof didn't leak). Very impressive. Besides being a little concerned that the roof might be sticky/tacky forever, this product seems great. It even coated over flex tape and/or previous patch material. Application material cured white (primer appears a little eggshell in color but seems to cure white and/or covered white by the sealant). The product leaves a surface that feels (after it cures) similar to the original "blended surface" (not thick, spongy, stiff, etc.). If this product holds strong through our wet season, I will be sure to coat/recoat the entire roof (I only coated approximately 14 x 16 foot square patch where our trouble/leak spots were). And/or use on my RV roof?

Followed the instructions and the reviews and had no issues. 5 Gal goes a long ways FYI. 30' camper with 3 slide outs = a lot of coats. I think I did about 5 thin coats and one heavy coat due to the weather conditions in October / November and I still have about 3-4" in the bucket. will spread the rest when weather is right in the spring.

First cleaned the original roof membrane with pressure washer, dawn dish soap, and scrubbed with a sponge. Dried completely then applied the liquid rubber brand EPDM primer and let that dry. Applied one coat of this white rubber every 45 minutes or so, for about 3 to 5 coats per day over three days. I applied using a ladder and medium nap paint roller with a six foot extension arm. Also cut edges using an old paintbrush that I didn't care about keeping afterwards. Cleanup with soap and water was easy, for anything that didn't fully dry out. Used nitrile gloves to avoid getting on hands, which was good because I got a bit on my arm skin and it sticks to hair very strongly. I would not want to have a lot on me to clean off. The roof looks great and has a bit of texture which seems to reduce slipperiness when walking on it. It's a bit "sticky" for heavy things set on it, but nothing has peeled up so far. I'm amazed at how cool the roof has felt in the blazing Colorado sun, and I definitely should have worn sunscreen while applying it. I used almost the entire 5 Gal bucket on our 25ft travel trailer, stopping when the remainder had too much dried "paint boogers" to go on cleanly. It was probably more than absolutely needed but figured the roof would last longer and otherwise the rest would have just been wasted. I primed and painted over existing lap sealant and TPO edge/repair tape that was in fair condition, and it seems like it will protect both for a long time. It adheres very well and seems quite flexible even in the cold. Newly applied dicor lap sealant seems to adhere well to this coating.

This roof coating went on simply and made our camper roof look like brand new! Just hope it lasts!
