Liquid Rubber Waterproof Sealant - Leak Repair Indoor and Outdoor Coating, Water-Based, Easy to Apply, Black, 3.78 Litres

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!!

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 ! *****

Very good used on my motorhome

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

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

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!

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.

Perfect for my Needs!
