Polycell One Coat Damp Seal 2.5L

This item is brilliant! We had two damp spots that just kept appearing. Just one coat of paint worked so well! After the one coat we then painted the wall with our chosen paint. No issues and no more damp marks appearing, . Highly recommend!

Excellent product. Covered brown damp marks on ceiling from recent leak in one easy coat. The smell is VERY strong and definitely need to air the room for a few hours after using

Value for my money good quality the paint it was easy to use no problem with the smell. The coverage on the wall was ok and I like it. Just hope I the mould do t return in the wi ter will give another up date when the winter kicks in.

I’ve applied this to several damp looking areas on a wall in my conservatory prior to re-painting the whole room. Covered the area well. Left it to dry then painted over it without issue. Time will tell t9 see if it has been effective. It has certainly made an immediate impact as the wall is still looking good after four days. Fingers crossed.

Absolutely great. Used in a bedroom that was really run down and needed completely redoing. The room had a lot of damp and since I’ve used this I’ve not had any problems at all. Says it’s once coat and it most likely is but I used 2 to be sure as it was really damp. One coat with a brush and one with a roller to really pack it onto the wall.

As described thanks

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 one seal paint is absolutely fantastic! We kept getting patches of mould on the ceiling and wanted a better solution than just spraying mould spray. I put a coat on of this, then went over it with a second coat a few hours after the first had dried. It’s been about 5 weeks now easily and it’s not come back at all! It’s like paint mixed with glue so a smooth roller is needed (like for gloss). Also be super careful when using it, it marks whatever it touches so make sure to keep everything covered and have some thinners to hand. Also eye covering is an absolute must - I got a dried fleck of it stuck in my eye, luckily my eye went crackers and it self resolved - be careful with this stuff. Otherwise it dries quick and decent value for the size. It also does smell abit so good ventilation is needed I think or you’ll get abit of a headache. Would recommend to solve mould issues in the home everytime though.
