Liquid Rubber Waterproof Sealant - Rubber Paint - All Surface Leak Repair Indoor and Outdoor Flexible Roof Sealant, Water-Based, Easy to Apply, Original Black, 4.75 Gallon

I used this for all my deck joists. I don’t k ow why ppl use joist tape. It costs SO MUCH money. This is the same thing and it is faster and cheaper. I used a paint brush to apply it. Threw it away when I finished. I painted 420 sq feet of deck joists. I did 3 coats. It dries fast. If you need to put it on thickly it will take a little longer to dry, but it will dry. There are no tacky areas at all. It isn’t messy-as in-it did not drip everywhere. It stays where you put it. It goes on super fast. What is everyone doing using joist tape?!!! That takes so long to do. Hahaha. If I would have used joist tape for my deck it would have cost over 300$. This cost me 50 bucks. I am a woman. A single mom. I am building my own deck by myself….and saving money is important bc I am a single income family. Even if I had the money for joist tape, I would not have used it. It takes too long to mess with. I painted all my joists in under 40 minutes for each coat. The first layer I put down was about 2 hours before a rain storm. It dried and the rain did not hurt it at all. It beaded right up. The next day I put the second coat on without any problems from the rain. I looked on so many sites to see if anyone else used this stuff for joists. On the big box store websites, if you look up similar products like this one, people ask questions and they get answers. I saw at least 6 people ask if they could use this for joists…and the answers were always vague. Like, they don’t want to say yes bc then you won’t buy their expensive tape. It’s the same stuff! Use this instead of tape. No…..it doesn’t drip everywhere and make a mess! That is user error: stop being messy!

Very good

Used it and it didn't a good job on the roof of my shed

Make sure it warms up by letting it sit in the sun for a few hours. It then spreads easily with good coverage. Flows into any cracks. So far no leaks after several heavy rainstorms

Did everything the container says 75 degree days 60 degree nights everything looked good now it's starting to flake after 5 days not sealing much of anything got several leaks

Received the product, it had separated, the large black lump would not mix completely with the liquid to make one mixture. Did not try to use it. A waste of money. UPDATE: seller contacted me with a full refund, great customer service. Would be willing to buy other products from seller

Easy to work with. You can feel the quality. Easily able to seal the container back up with a hammer and use the rest later. Works great on old shingles. Easy to clean up.

I used this for the flashing around roof heat pump, very easy to apply. I would buy again.
