Polar Bitumenseal Grey Paint - 5KG - Instant Waterproof Bitumen Roof Sealant - Ideal for Leaks, Cracks & Pitched Roof Repair - Concrete, Brick, Asphalt, Drainpipes & Gutters - Easy to Apply

Easy to apply and helps prevent leaks.

Fantastic product - will stick with this brand now, because everything they make is top notch.

This was the second tin I’ve ordered. No problems with first tin but second was dented and deformed although neither of the boxes it came in were damaged. Liquid easy to apply, initially thought it would have been thicker consistency. I used a roller and an extension pole to do my garage, it was a quick and easy process. Just need to wait and see how it holds up.

HAVE NT HAD ANY RAIN YET TO CHECK IT OUT ...BUT WENT ON GOOD.

I had a few builders quote me and the recommendation was change roof at a cost of £10,000. I almost fell of my chair and started researching 'how to repair a leaky roof'. I took a leap of faith due to not having the money for the repair and purchased 3 tins, 2 paint rollers with long handles, 2 paint trays for a total of under £200 and with a little help from my son, spent a day applying it to the roof. To my surprise it worked like a charm. Two months of crappy English weather and no more leaks with the added bonus that I can't tell the builders where to stick it ;-)

Absolutely brilliant stuff, easy to apply and does the job, excellent product

Excellent coverage on the outside of a shed, covered some damp patches extremely well

Good, but had to give 3 coats on red felting when on the tin it says one coat.A bit expensive but needed it in white so had to pay it. Not sure if it works yet but it does look good
