Polar Premium Clear Instant Waterproof Felt Roof Sealant Paint 500ml, Emergency Felt Roof Repair Sealer for All Felt Roofs

Brilliant product and really easy to use, only recommendation is keep it in the house where it’s warm prior to use so it’s not as thick when applying. Did a brilliant job though, would recommend

Installed easy & work well, also dries quickly

Bought to seal a bituminous roof panel that was degrading and leaking. Easy to brush on, strong smell but no problem outdoors. Did job brilliant. Had bit left to go on coal bunker too. Small tin, did one partial roof sheet and half coal bunker lid.

I had developed a leak along the join in my shed roof where the clout nails hold the edge at the overlap. Rather than redoing the whole roof again as it had only been done six months prior I decided to try a sealer. It has been applied now for about six months and we have had some pretty horrendous wind and rain during this time but there is absolutely no sign of any leakage in the area of the joint anymore. Simple to apply with just a brush straight into the felt and job done. Definitely does what it says on the tin. First class product imo.

Easy to use

I was getting a couple of leaks into my summer house from the roof, probably the through the tacks, thought I would try this instead of shelling out for new felt etc…This worked a treat for me, we have had plenty of rain in the few days since I applied this, and it has not leaked, really happy, it does leave a mark on the roof where it is has been applied but couldn’t care less as long as it prevents the leaks, would recommend this 👍🏻.Also, would wear gloves and old clothes when applying this to your roof.

Sealed cans look professional, expect material is good.Have not used - for next year.

Worked very well for sealing felt on my cellar roof
