Liquid Rubber Waterproof Sealant - Multi-Surface Leak Repair Indoor and Outdoor Coating, Water-Based, Easy to Apply, Original Black, 1 Quart

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.

Really good stuff for cheap roof repair. I’d probably only use it as a temporary solution however as it does seem to degrade after a few years

Applied 4 coats to my osb timber shed roof within a 2 day period of no rain about a month ago.. We've had some heavy rain since and also some really hot days and so far so good.. have enough left for one more coat. My roof is 3m x 5m.. goes on brown then turns black quickly... Time will tell..

Bought with the geo-textile membrane and both really worked! The conservatory adjoining my bungalow had always leaked at both ends of the guttering and repair by a professional hadn't solved the problem. I thought I'd have a go when I came across this product at the end of August. I applied two coats, 24 hrs apart, and would have applied a third, but the weather changed and we had a deluge. Result: absolutely no leaking and a wonderfully dry conservatory - I couldn't believe it! Now November and still dry. NB: This stuff is easy to apply by a complete amateur (me!), but you need to be really thorough and seal absolutely every possible angle where the water might get through, laying the geo-textile membrane right up to the edge of the guttering, as huge amounts of water come off the roof. Can't rate this stuff highly enough!!

Very good used on my motorhome

Used this to seal my van roof , after ford couldn't find a leak on a 19 plate independence , so far it has sealed the roof and stopped the leak which was mid roof and near electrics , used two coats and did it vertical then horizontal , saved me thousands ! *****

Product is exceptional. However they used to sell it in the large 20L drum and they have stopped. So it is very inconvenient ordering in the 3.98 gallon buckets. So I hope the supplier is taking note of this as they should be offering it in the larger drum/bucket size

....really really good stuff that's literally may have saved me hundreds for my next holiday. It's a bit too early yet to fan fares and streamers as the real winter test is yet to come. But so far so good to give this product a cautious 3*** stars. The coating spreads easily enough to cover the desired area with a brush and comes off hands easily enough if hands washed with washing up liquid and alcohol solution. It been on my rubber membraned roof for a approx a month and have had a few down pours without any water inlet issues so far. Will update review and star rating when this has been more thoroughly weather tested.

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!

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-
