## Description

Polar Leak Seal Clear Paint - 500ml - Instantly Waterproof Roof Sealant - Ideal for Leaks, Cracks & Roof Repair - Concrete, Brick, Metal, Drainpipes & Gutters - Easy to Apply : desertcart.co.uk: DIY & Tools

Review: Very impressed. Performed exactly as stated and sorted my leaky roof. - 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.
Review: Pretty good - 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.
