Polar Leak Seal Clear Paint - 2.5 Litres - Instantly Waterproof Roof Sealant - Ideal for Leaks, Cracks & Roof Repair - Concrete, Brick, Metal, Drainpipes & Gutters - Easy to Apply

Used this to repair/seal a lead lined bay window roof and I am very impressed. The tin arrived in perfect condition, the lid was securely sealed with metal clips and the contents were complete. Tips: mix/stir very well before use to make sure the fibreglass strands are mixed back into the paint (only the black and grey paints I think). Wear a good quality face mask as the paint gives off very strong vapours. The instructions warn you of this. Apply a couple of coats depending on the nature of and damage to the surface being painted. I applied 3 coats to be sure, but the 3rd was overkill to be honest. Very pleased and impressed with the product. It's sorted the problem for me.

Used this a few weeks ago to repair a small cement crack above my bay window. I have not seen the annoying damp patch inside the bay window since.

Definitely very good, stoped the mould in my bathroom.

I used on a leaking shower tried everything but couldn’t find or fix the leak. Applied paint and so far leak has stopped 🤞.

Very good stuff last for ages

Does what it says on the tin

it's very good ,sorted my garage roof out.

works very well

This stuff is exactly what I have been looking for. Other products were very thick and after only a year on my roof have started to split. In fact this stuff is so good it has kept the rain away from our home, except for a couple of showers, for about 3 months now! Regrettably, our water bill has gone up keeping the yard alive. :)

Small gaps seal ok but wider openings require several coats. Be sure to let it dry between coats.

EASY TO APPLY

I bought this to seal up six leaking seams in rain gutters. My problem was gutters were 24 feet high and I had a 16 foot ladder, so you can do the math. The paint brush I used on a 8 foot pole could not apply this sealant with enough pressure to be effective. You really need to put his on with heavy brush strokes loaded with the sealant and unfortunately I was not in the position on the ladder to do that heavy enough. After sealing up six seams with one coat, it rained 48 hrs later and all seams still leaked. Im not giving up on the product. I'll try to heavy brush it on once I rent a 28 ft ladder. But, to be effective, I believe you have to brush it on from a foot away with heavy pressure strokes and lots of the sealant on the paint brush. Also, its real sticky so wear disposable gloves to make clean up much easier.

Applied to chimney flashing leak. this stuff finds holes and seals. Thin and flows enough to get into cracks yet thick enough to control where you want it. Used many different roof patches and sealers, this one beats everything. One application, no more leaks.
