Ames 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)

This roof coating goes on smoothly and provides a strong, flexible seal. The white finish looks clean and helps reflect heat, keeping things cooler. It’s thick, durable, and really does stretch as advertised, making it great for sealing cracks and protecting the roof. A solid product that gives peace of mind knowing the roof is well protected. Highly recommend!

This is an amazing product. Stopped all the leaks.

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.)

Used this on an older pop-up camper that has had a life. Most of the paint on the roof was down to the aluminum, and someone had done a home seal job with about 15 tubes of calk. Needing to do something a bit more legitimate, and give the camper some longevity, I decided to purchase this along with the removal of all prior sealing attempts. After cleaning off the old gook, and resealing seams we applied this over the course of a weekend in several coats. Here is what we found. A year later, its held up wonderfully- better than the paint that covered it, for sure. The coating goes on very thin. It will take several iterations before it becomes solid white and thick We used more than we thought. The lid to our small pop-up took about half a gallon to provide a reasonable coating. Dry times for us were much shorter than the 24h it recommends. This may have been due to low Colorado humidity, and that we did it in a controlled environment inside The coating takes pants and other things very well. After a full day of dry time, we were able to coat this with paint (Rustolium water based) and it adhered well and looks good. Time will tell on durability, but for now we are happy with the results. I would recommend this if you are looking for a paint like substance to seal imperfections on a roof.

Excellent product! It makes my old flat roof shine again!! I feel like it will give my roof at least another 5~10 more years. Really worth the money. I even use it to cover my wood window frames. It seals the cracks very well.

Perhaps you could find equal among similar costing products, but for me this product is tried and true. Sure you could buy paint for one third the cost, but what do you get: a lot of water added. Or at half the cost: less good adhesion, less good stretch, less good mildew control. This is a labor intensive project, so do yourself a favor and buy the good stuff you will be so much happier later on. Its the same old logic: good paint pays for itself. To apply, get a bucket, a short and long pole, a good ladder, a paint roller holder, several 1.5" nap roller, old clothes, a weather forecast, no trees dropping leaves or blossoms nearby; dump about a gal on the cleaned up roof surface and spread with the roller. Sure it says water clean up, but throw the roller away, think about throwing away the bucket too. Under perfect conditions, I accidently got a little of this on the aluminum siding and tried to scrub it off with a wet paper towel five minutes later unsuccessfully, this stuff really dries quick and sticks good. It requires sunshine to activate, so make sure its a sunny day, you might even have to swap rollers if it dries on the roller during a long hot day. This is plastic paint, so expect to do at least two coats and repaint your roof every eight years to continue protection. Applied properly and enough, this will stop leaks, significantly cool your roof temperatures (the difference between applying the first and second coat is extremely big~you will be able to sit comfortably on your roof after applying this.), reduce wind damage (my neighbors have had two new roofs, while I am just recoating mine), delay getting a new roof indefinitely (until you get to the point of the material underneath the roof decays if it was already exposed to water damage).

Bought this for my aging RV camper. It was rated well, went on easy and did the job. Great price.

This is the 3rd gallon, I have purchased, excellent multiuse product. Does not seem to become yellow with time! Excellent service and quick delivery. Alexd
