Roof Coating/Sealing using NovaTuff RC-100 Flexible Epoxy Roof Coating

[sgschwend]

As part of our trailer dent repair of the rear 5 skins we decided to apply a roof finish that is also a sealer.

In researching the three chemical types (acrylic, silicone and epoxy) I decide on the catalyzed epoxy type which has a harder surface finish to support walking on it. Product: NovaTuff RC-100 Flexible Epoxy Roof Coating, made in Texas.

Here is two images of the first coat. I purchased 3 gallons for this 25 footer. I think 2 gallons would have been OK.





The next step will be to clear coat from the beltway up. The rear four panels have been stripped, you can see how the upper sections the clear has failed, near the beltway however, the finish looks good.

Here is a closeup after the second coat, orange peel likely a common result. I was able to re-install the AC too, second picture.

Clear coat on the rear section. The sides and front next year after it warms up. You can see that the top curve part the clear coat is shot.

Update:
Results after two rains, show no leaks. Previously there were: curb side rear leak, across the rear leak, leak just in front of the door, and across the front leak.

Previous attempts to stop the leaks included resealing windows,skin seams, and awning/hardware. I did find the a leak at the front vent but knowing that there had to be more leaking locations lead me to follow the idea of sealing the top completely.

Looks good! The sealing first may have had a lot to do with the leaks being stopped but the epoxy sealer being white will also help with temperature buildup on the roof, controlling heat absorbed on the bare aluminum from the sun to keep the trailer cooler. Keep us updated on your progress. Ed
