Polar Specialist CoatingsPremium Grey Felt Seal - 2 x 500ml - Instant Waterproof Roof Sealant - Ideal for Flat or Pitched Felt, Shed & Garage Roofs - Easy to Apply

My shed roof was starting to let in water in various places, the shed is difficult to get to to try & re-felt it as it’s wedged between the garage & fence (not our choice of location)We purchased this hoping it would do the trick. Armed with a step ladder & an extendable roller, my husband covered the whole roof with the sealant. It is a sticky, gooey product & does smell like a strong glue, but that fades pretty quick. Coverage was good & there was no change to the overall appearance of the roof (not coloured)Anyway, with the endless amount of rain plus storms we have had over the last several weeks I am delighted to report the shed is water tight again. We think this is a good quality product & we will definitely re-purchase if needed.

( The selling is dry )it s really good 👍

Excellent product. The felt had come away from my shed, and I thought I'd give this a try before messing about stripping the old felt etc.I didnt expect the paint to be so thick, but actually that made for a better seal because I painted over the area that was missing the felt (around 20cm square) and then I applied it thicker where the felt had ended/torn... and then along the entire seem where the felt overlaps just in case, and to be sure no rain could enter there either. The instructions say you can use a roller... which I did to save me having to climb onto the shed (small ladder) but it was actually quite difficult to apply the paint to the roller due to the thickness (yes I gave it a decent stir) so I'd suggest using a good paint brush. I painted the roof around a week ago, just before the storms, so I checked the inside today and the floor has dried up. Top product, and I'd say 1 litre would cover a 6×4ft roof easily with some to spare.

Delivery was ok ,I have had three deliveries of this feltseal ,first delivery of 1ltr was light coulour grey and had a paw symbol on the tin the second and third deliveries had no paw symbol and was a darker gray and thinner to apply won’t order again in case this happens again, if I used the last tins they delivered my shed roof would be a different colour grey and would look terrible.

This is an alternative to re felting yours shed roof. Basically paint it over the nail heads on the felt and Bobs- your -Uncle job done recommended this product.
