## Description

Polar Leak Seal Paint - 1L, Grey - Waterproof Roof Sealant for Leaks & Cracks - Seals and Protects Roofs, Gutters, & Drainpipes from UV Damage - Easy One Coat Application : desertcart.co.uk: DIY & Tools

Review: Does exactly what it says on the tin - I used this on an old tiled roof which had been leaking because some of the tiles were cracked and the leadwork needed replacing. This is a far cheaper solution than replacing the roof, and worked perfectly: it even 'glued' the lead back to where it should be. No more leaks! Even in the winter storms, with driving rain and wind. Easy to paint on any surface using a masonry paint brush. Be prepared to bin the brush afterwards; it'll be ruined. Superb product, heartily recommended.
Review: A transparent, though pungent, solution for roof leaks - 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 impressed. Performed exactly as stated and sorted my leaky roof.
*by T***F on 8 November 2025*

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.
