Liquid Rubber Waterproof Sealant – DIY Leak Repair Coating for Flat, Metal & Low Slope Roofs, Foundations, Gutters & More – Flexible Protective Membrane - Black - 1 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.

If you want a sealant that can handle high water temperature and last the test of time, you found it. I used this to seal my homemade solar water heater tank back in early 2022. Today it still hasn't leaked although the tank has reached 130 degrees in summer. Four years of abuse and still reliable is a solid proof of its quality.

The odor is low, it applies easily with a brush, and builds up well making a nice waterproofing on wood, synthetic decking, and metal roof. Dries quickly. It's expensive but it works.

My project that I used this on is over three years old. There is slight cracking under full sun but otherwise it has held up well. It deals with constant watering and has adhered well to my project. It wasnt hard to apply with a big brush but it does start to harden quickly. I still have some leftover because it spread so easily as is.

I have an older 12 x 18 foot gambrel roof storage shed used for lawn mowers, tools, etc. There is no telling how old the shed is since it was here when we bought our place 15 years ago. A friend of mine said he'd never even seen roof tiles like were on my shed. Over the years I've lost a couple of tiles, the tiles were getting very worn and you could close the doors and see light coming through the roof. Needless to say, rain water was not my shed's friend. Thought about replacing the roof but the cost was way out of reason for a shed. Found this product and after reading the many reviews I though I'd give it a try. I replaced 2 roofing tiles and started coating the roof. I put 3 coats on the rood, a little less than 3 gallons. This stuff is amazing. I would have never believed it, but my roof is completely sealed. I can't even lift or separate the tiles now. There is no light penetration and we've just had 4 days of constant rain and there is no leaking. It does go on brown in color but soon changes to black. The first coat took a little longer but after that the second and third coats just went right on. I managed to get a lot on my hands but it washed off with soap and water. I had about 1/3 gallon left and since there is no way you can reseal the container I decided to coat the wood on my trailer. Can't say if that was a good idea or not but figured it couldn't hurt. For less than $200 I got a completely sealed roof that I expect will last many years. If not, I'll just get another gallon in a few years and re-coat it. I highly recommend this product. Read all the reviews to insure it will serve your purpose, but I am very thankful I found 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..

great product.

Used this around my garage around the bottom edge where the cement fillets are as I was getting water come through when it rained heavy. Brilliant stuff, just paint it on use an brush but it does come off with white spirit.

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!
