Polycell One Coat Damp Seal 1L

Amazing stuff, even used it as a undercoat/ primerI will pre warn you, wear a mask and get pets/ kids/ pregnant women out the house or away.The smell is pure poison, I had headaches and was dizzy. Even in a well ventilated room.Besides that, amazing and would buy again to tomorrow!

Used on son’s bedroom which has black mould spots. Washed wall and once dried painted on and months later no mould. Very good product

Great product, used in a few patches over the home where there had been water staining (works very well on this) and some ongoing damp issues, this particular patch was the worst. I removed some of the damaged plaster and used a poly filla product and sanded down then applied the paint. So far the damp has not returned. There are other patches which have returned, however there is an issue with the external wall so will reapply once this issue has been resolved! Paint is very thick and hard to work with but it definitely does the job, and dries like an eggshell matte!

Easy to use works great

Bought originally for my daughter as had a damp patch showing on her kitchen wall. The source of damp corrected and panted with normal paint but still showed. Using this paint it covered perfectly and now no patch. Bought second can for a bathroom ceiling at my sons and same result . It is truly impressive .

Having almost sliced my hand trying to open the tin, I got into the paint. The lid is incredibly stuck on, using a coin they normally pop up this kept sharp raised edges around the lid.Ive read reviews that said its really runny.......mine was the opposite, the thickest stuff ive ever used in 30 years of having my own house to maintain and decorate. It was thick as heck, like thick PVA glue and it was really quite difficult to apply. No chance with a roller and hard going due to the thickness with a brush. Once on the wall, it didnt spread like normal paint at all. The smell wasnt too bad after a short while, left the room well ventilated. It looks like Im going to have to get another tin of something as its not covered very well in one coat at all. The brown marks left from where I removed some areas of mould has shown through again.Make sure you wear gloves, and sleeves and nothing that you wouldnt be sad to throw away - as the paint sticks like glue, to clothes, any material and skin.Disappointed that it doesnt "do what it says on the tin"...one coat hasnt covered the marks at all.

This is really tacky but does the job hiding the damp. Worked really well on coving and walls

Pleased with this - VFM for sure, good thick coat and months later still looks the business. Dries quite quickly. Smell is strong but again disappears quickly after drying.
