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

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-

Great stuff very impressed . I sealed my steal trailer . Spread easy , went a long way , dried fast and saved me a lot of money taking it somewhere to be done .

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.

Goes on and looks brown but dries black. Easy to apply - like a thick paint. Seems like it will work great - dried well. Will give a better update on how well it works after it has been on for a period of time. Only had it on for 1 day.

The best product I have ever used for concrete sealing. Also excellent for repair on my EDPM rubber on roof. Works on about everything. Will buy again

I used this to seal around my chimney flashing when I installed a new metal roof and it worked well. It is easy to apply with a paint brush and adheres really well. I have not had any issues with this product and no leaks. I would recommend this product.

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..

Used this to seal cracks in our deck before we redid the floor. It has filled those cracks and held up great in the rain storms we have gotten. Coverage is good. It is thick but perfect.

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!
