Waterproof Sealant - Roof & Gutter Coating, Black, 1 Quart

I had a fountain that leaked through some cracks. I tried the brand or sealant advertised on TV, you know, the bias with sealed screen door in the bottom. Seven coats, it never really sealed and lasted about 6 months.3 coats of this stuff and a year and a half later, it’s sealed up tight. I really like this stuff. I wonder how it works as underbody protection on a car…..

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.

Worked great for a rainwater leak between the neghibors cement wall and the new aluminum flashing I installed over the new framing of our basement Bilco doors. Taking advantage of a recent heat wave, in addition to heating up the liquid rubber container in some warm water prior to pouring really helped get the product thin enough to run down into some very tight spots. Wife and I used a large plastic medical syringe along with some 5/16" OD polyurethane tube that screwed perfectly into the Luer-Lock end of the syringe to inject the rubber into the problem areas. It was well worth the price, for our application, IMO.

I never bought or used Liquid Rubber before. I bought a quart to make a Civil War era ground cloth. The can I got was more like tar or PlayDough than a liquid. I was able to work the tar-like rubber into the canvas. The picture shows what it looked like after being stirred. The blanket turned out will, even though it did take some effort to work the rubber in. It has dried and appears as though it will be water resistant and it is also flexible and not tacky.

I used a foam brush to apply this to a water fountain container. Applied a second coat the next day. It’s been on for a couple months now and shows no sign of releasing from its base. I also used it to coat an overflow drip pan on my central ac unit. Here too adhesion was great and now my galvanized drip pan is protected from corrosion. I was impressed with the coverage from the container. Still have about 1/3 container for my next waterproofing project.

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..

Worked great to repair a rain barrel an put in gutter joints

Buyers beware ! This product is not a fix all it’s mainly is meant on roof leaks or flashings. Not good on foundation walls with stress cracks that leak or cracks between foundation walls and concrete floors that have hydrostatic pressure. Customer service rep was very rude and hung up on me. Only offered 50% refund on the product that failed.

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 dryI would highly recommend using this Canadian made product

Excellent item. Bought it to waterproof the base of rabbits hutch. Done the trick nicely. Incredibly sticky though so had to throw away paintbrush afterwards unfortunately

Awesome sealed roof after a couple of coats 👍

Brilliant stuff stopped my leak.after 1 coat.Ihave used 2 coats and highly delighted
