Waterproof Sealant Black Waterproof Coating 1 Gallon Leak Repair Coating for Flat, Metal, Roofs, Foundations, Gutters, Indoor & Outdoor Walls, Bathroom, Kitchen, Garden Leak Liquid Sealant

I used on an epdm rv roof. Worked well and coated nicely but took a bit more than expected. I would use again in the future. I do recommend following guidelines of cleaning and using a decent primer. I read reviews before buying and didn't see any bad results and I felt cleanup was simple if done quickly.

Good

This was great! I made a knight in armor out of cardboard to put in a castle club house. It will last forever nowlol

Two coats of RV roof sealant applied and after it dried it did not adhere to the roof.It peeled off and the wind blew it off.The sealant was very thin and watery in texture.

Seems to work well at sealing out moisture. Be aware this formulation is very thin/consistency of water.

This produt is worthless. Spent alot of time and effort prepping for nothing. Product flaked and chipped off . Whitewash would have lasted longer. This is just sad.

The first gallon I bought was good so I order a second one and it was bad. I sent it back and received another bad one

This sealant exceeded my expectations. I used it to repair leaks on the roof and some cracks in the bathroom, and the results were excellent. It’s easy to apply with a brush, has a great texture, and dries quickly. I love that it’s both waterproof and UV-resistant, making it perfect for indoor and outdoor use. The black color gives a clean, professional finish. Great value for the price—I’d definitely buy it again.
