Polycell Stain Stop, 250 ml

Best stain stopper on the market 100% performance

I have used this product a few times over the years a yellow water stains on ceilings and it works a treat. It's so easy to use, you just spray on and the stain is gone. No need for paint brushes or cleaning. Be careful of the paint dust it generates though, you can see this floating through the room and it can't be healthy to inhale this so make sure all the windows are open and don't stand near it for long. By the time the dust lands it's dry and can be wiped up - much to my relief when thousands of paint speckles landed all over my black glass hob in the kitchen! However I have recently used it on a badly stained wall which had had quite serious damp problems. Once the damp was gone it left brown stains on the wall which I tried to cover with this product. Firstly the amount of paint in the can wasn't enough and secondly it hardly covered the problem. However a few coats of the liquid Stain Stop paint from a tin seems to have done the trick. I'd definitely recommend this but make sure you pick the right product for the problem - small pale areas = this, larger dark areas = tin of Stain Stop paint.

This product really does completely cover stains. It is so easy to apply especially to ceilings and saves having to repaint the whole ceiling. You simply can't see where the ceiling (or wall) was stained and blends in absolutely perfectly with surrounding white paint.

Excellent product. Easy ti use and covered stain very well

Bought this spray to cover up a water stain due to a leak in our roof. It was easy to use and did the job of covering the stain well. It is fairly strong in smell so make sure to keep the room well ventilated. It is a very fine spray and goes far so be mindful of that when using & prep accordingly. But overall did a good job at repairing our wall.

So my upstairs neighbours had a leak from their boiler. This left a large outline of a water stain across my ceiling. Having chosen to paint the ceiling, I bought this to pre-cover the stain before painting. I applied 3 coats of this to the area, when it first goes on it looked like it has covered it, but as it dries it comes through again. Having applied 2 more coats it was still there. I hoped that after to coats of emulsion it would completely be gone, but alas it is still visible, not as bad as it was but is still visible. The application is quite easy, just point and spray. As other users have said it does leave a mist which dries as it falls to the floor so easy to hoover up. The smell is strong so windows open after application. Overall, it didn’t do for me what I needed to or should have done, for the price I expected it to do as it said and block the stain but it didn’t. The 250ml also doesn’t cover very much so bear this in mind for any project you’re considering.

Works to cover stains , it leaves a powdery residue, would buy again but use in warmer months so I could air the house out after .

I love this product, it goes on well and has saved me from lots of water stains coming through paintwork over the years. Of course it would be nice if it were cheaper, but it does work and you can paint over it easily.

bloque très bien les tâches et fait une bonne sous couche avant la peinture définitive.
