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.

Have used on several rooms around the outside edge of the wall and so far good results, no moisture stain so far

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.

Well it's the one stain paint I have used that's actually covered the stain and kept it away for now
