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

It went on very well with a brush.Just got to wait and see if it works successfully when I fill the pond with water to see if there are still any leaks. Hope not.

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..

Easy to apply brushing in the cracks not high in fumes great product. Does the job

Awesome sealed roof after a couple of coats 👍

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

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

I was thrilled at first. I used 5 coats, they were brand new terracotta pots that I was turning into selfwatering ones, so they needed to be waterproof. I waited a week after applying the rubber to put my pot inserts into the planters. When I lifted my inserts a couple days later, the rubber stuck to them and ripped. It says on tin that it cures in 48 hours, so I wasn't impressed, I let it cure a week before I put water in the pots. It'sa no for me.
