Polar Specialist Coatings Clear Leak Fix Paint - 85 oz - One Coat Waterproof Sealant with Reinforced Fibers, Instantly Seals Leaks & Cracks for Roofs, Drainpipes and Gutter Repairs for Exterior Use

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 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.

Worked great for sealing my bathroom sink. I hope it also will be work on our metal roofing as it also leaks bad.

Takes awhile to get, but works as described and stopped the leak as advertised.

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.

Seems to work well

Takes forever to dry. Strong smell. But the worst part is that even though it goes on clear, after only 2 weeks it has turned a caulky white color, like a super hard water deposit. Now I am going to have to try and paint over it with black.

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.

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 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.

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
