Njl Roof Coating Brushacryl Fibre Reinforced Roof Protection Black 20KG

Did a really good job,don't skimp when applying do what it says on the tin👍

Good product done the job

Seems to be working

This seals as it states on the tin not cheap but well worth the money and covers area really well Have no complaints only compliments. Try it yourself this supplier is true and good on delivery.

I first tested the product on a satrarted porous concrete blcok with a damp surface. I left it overnight at 5-7 degrees C in a damp environment. By morning it had set fairly hard and was very firmly adhered to the block. I then applied it a single coat in dry conditions to a cracked chimney capping which was damp after several days of rain. The temp. was 7 degrees. By the end of using the 1 kg tin the product was becoming more viscous but still went on OK albeit a little thicker. The fibres help prevent drainage on vertical surfaces. It provided a waterproof seal. It's acrylic so should be UV resistant. Time will tell but a very good product if applied in cool conditions and in accordanece with the manufactureres instructions.

It did at the time a great job but after 4 weeks did slightly show some damp,

Excellent cover easy to apply, would definitely recommend.

It stopped my shed rotting
