Liquid Rubber Waterproof Sealant – DIY Leak Repair Coating for Flat, Metal & Low Slope Roofs, Foundations, Gutters & More – Flexible Protective Membrane - Black - 5 Gallon

I waited to post this review until it rained to give honest feed back. I had a horrible leak in my garage. I bought this in hopes it would save me the cost of a roof repair. It did. Works well, easy to apply with a roller brush. My S.I.L. applied a thin coat as directed on a warm day. I had no problems with it curing at all. I would recommend this product to everyone and if the problem comes up again on another area of my roof I will not hesitate to buy this product again for that fix as well.

Purchased this Liquid rubber waterproof sealant for the roof on the greenhouse. Applied with ease and dried in a reasonable amount of time. Seems to be a good quality product and anyone needing such a product should consider this company.

I did give it a 5 despite one issue- The positive first - Had a leaky flat roof (slightly racked) over my garage - Was going to have it done professionally for over $5000 ish. To replace the existing membrane. Well Liquid Rubber has a help line email so I asked them if this product would work well - and gave them details of my roof etc. - I got an immediate response and then ordered 10 gallons, based on the surface area etc. This was my bad - but to do I believe the recommended 5 coats it took about 6 gallons - since this stuff is bit pricey I could have ordered 5 gallons and 1 gallon and saved $. Good news is the roof did not leak anymore, and looked good. Here was the complaint- I had left a black rubber garden hose on top of the garage months after applying the sealant- maybe it was up there in the middle of August for 3 weeks- Well when I went to remove the hose it was stuck to the roof - It was not that hard to pry it away but it actually left kind of a stain on the roof. So my bad for leaving the hose there but I did not expect that. I have to check but I will have to do this again at some point-

Good product

We have tried nearly every type of roof caulking out there. The Texas summers on a metal roof are brutal. This and the paint are the only thing that have held up. They flex and still seal where 2 pieces of metal contact where we have had a roof leak for years... no more leak. It set solid in 48 hours. Application was really easy and forgiving. We put on 3 layers of the paint on the tape just to be safe which surprisingly didn't take very much to do. No running or bubbling found. Even after 120 degree Texas days making the roof well over 150... and it still held. No cracking, running.. nothing. It is our go to now. Well worth the money and the only roof sealant that still seems to work. Mineral oil to clean the brush, easy to apply - just like a thick paint. Dries in 24-48 hours. 3 layers with the tape was enough to handle 7 inches of rain in 3 hours no leaks this spring. Thank you for making this and please keep selling it!

We used this “off label” on wood fence posts around our ranch. We thought we’d just cap the posts and top rails to seal the end grain. We completely covered a couple of gate posts and liked the look, so off we went one post at a time. Expensive but effective. $200 per bucket hurts and takes planning to swallow slowly. Try a little and go from there. Love it for what we used it for.

A little nervous about this product I haven't got a heavy rain yet since I've used it but it doesn't seem to dry being sticky it's very stretchy which maybe that's a good thing I don't know 😕 I've put four coats of it down hope it works.. Also I've used Aims block and wall about 4 years ago and it when it dries it's pretty hard I did four coats of that and it's been holding the water back so I know that works. I got a picture of both on stir sticks in my review here..

It did what it was supposed to do I was impressed.

Good quality

This product is made in Canada so it was a no brainer for me to purchase it. I used it in my shed the ceiling was leaking after a rainfall. The application was so easy. No difficultly applying the coat on the ceiling .. No dripping. The product dried in a very short time. I checked just how good this product is after the last rain full. My shed was bone dry I would highly recommend using this Canadian made product

It kept out the rain

Very good, but overpriced with shipping etc!

Perfect for my Needs!
