Maximum Stretch - Waterproof Sealant Membrane - Perfect For Roofing, Repairs, Concrete, EPDM & Wood - Liquid Rubber Sealer - Up To 650% Elastic - Made in USA, White, 4.6 Gallon (Pack of 1)

Works as it has great durability worth the price no issues water resistant, easy application, looks great when applied correctly, stopped my leak no more issues.

Used to seal a flat roof on an older home. Worked beautifully and was easy to apply.

I used this product to cover a fairly large nearly flat roof with a second coat a couple of years after the initial base coat of 100% silicone. The application process went well enough with a roller brush & extension pole. The 5-gallon bucket had to be stirred for a while to get thoroughly re-mixed, but it's a necessity. Otherwise, it's been a good outcome so far (of course time will tell how well it holds up in the sun at 4,000 feet).

I used this on my camper roof. It's a smooth metal roof in good condition so I didn't want to cover the good roof surface if not needed. However, all the vents & railings, etc., were getting a little... tired? looking, around the screws & stanchions. So I cleaned and prepped the entire roof and all the items. Then taped off to only paint around the perimeter where the railings and vents and A/C are. (Basically, everywhere anywhere near screws.) Cutting in everything was done with a brush. The paint is much thinner and slipperier than I expected. Thought it would be more sticky & heavy. So it didn't cover easily. (had to use a soft brush to not pull to much off when applying. Rolled the rest and it had a tendency to not lay down very thickly. Also, a big problem, was that it bubbles a lot when rolled on. If you let it sit a few seconds (to tack up) as you move on, then go back and lightly roll over it to pop the bubbles and even it out, it gives a really nice even finish. Sadly, I had to do that 3 times to get enough thickness. In the end, it came out very nice. This stuff reeeeally sticks well (on almost anything including your hands). I saw quite a few people say it didn't cover as much as stated. But I found it covered quite a bit of surface and all 3 coats equaled about the amount they stated for coverage. (In my case, about 50 sq. ft. & 1/2 can.)

This is a great product. It’s easily applied and hardens sufficient to repel a rainstorm within an hour. I was worried about the coverage. The camper trailer I used it on for the roof with 7 feet wide and 22 feet long. I couldn’t see coverage statistics and lots of people had indicated to coats with necessary. I agree with the Two coats needed to sufficiently reseal a camper roof. This is easily accomplished with 1 gallon.
