Polar Leak Seal Clear Paint - 500ml - 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.

Did quite a good job on a shed roof. I used it outside and inside on the joints. Some leakage later, but only in one place, so I'll just use silicone sealant to fix it.

A good quality product that helps to waterproof my roof

Polar clear fix spray

Does exactly what it says on the tin, very easy to use and very effective. Great product

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.

Very good to seal leak in glass windows. Clear seal does not show

Like you reading my review, I read those of others. So, I ordered 2 cans. I hoped that this 'fix' the porch roof that keeps getting random leaks when it rains. The roof is that poly plastic & is made of 2 sheets. This means the join runs the length of said porch. I decided to spray on the inside. I couldn't be bothered getting the steps out to sprap outside, I'm lazy like that!! So, what's my verdict....it is working! Since applying it we have had some good downpours, & all is dry! I'm glad I decided to purchase & there's plenty left.
