Polar Leak Seal Paint - 500ml, Black - Waterproof Roof Sealant for Leaks & Cracks - Seals and Protects Roofs, Gutters, & Drainpipes from UV Damage - Easy One Coat Application

Used it on a balcony and the rain just runs off now.

I like this product, but it sometimes requires two coats amd needs to be applied quite thickly.

Great easy to use

Wonderful stuff. I’ve used it on patios, shed roofs, gutters, great coverage.

Quick delivery, package well wrapped and arrived undamaged, good communication throughout, great value for your money

Good for a quick fix

This was applied to a felt roof which had had a small leak - being transparent, it doesn't seem too obvious but it does add a more reflective coat so does show under close inspection. Paint consistency is very thick, making it easy to slather on as per the instructions, while giving your brush hand a good workout! The surface remains sticky after drying so will tend to collect debris more. However (touch wood) it does seem to have worked so far in fixing the leak. The product safety warnings should be carefully observed. Even while wearing a facemask and outside, the fumes were noticeable. This is very much an outdoors product.

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.

The product works great. I had two water leaks and I brushed the leak fix in the area on the shingles and we had a rain the next day and not a drop leaked in. Thanks

this product took care of every leak i had on my metal roof. highly recommend this product. when i applied it i put it on with a paint brush using strokes across ways and then up and down strokes. it works great

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.

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. :)

Wish they had bigger buckets
