We had bought a house where the previously owner had painted knotted pine wood and all the knots had shown through, so using aerosol stain stop was a quick, easy and effective way to produce a great finished job. Fully recommend it.
Frustrating and disappointing

Bought to block in small grease stains left from blue tack on walls and ceiling. Took all appropriate measures to prep the surfaces and the stain, then used this stain block exactly as directed on the can. As a stain blocker it appeared to work very well, the grease spots were no longer visible on all the surfaces prepped for painting. The ceiling needed two coats of Polycell Crack free White Silk Emulsion to cover the stain blocker as it shined through the first layer. The walls however were a world of woe. After 3 coats of B&Q Silk, the stain blocker was still VERY visible as white marks through the layers of yellow paint. Admitting defeat I went back into store for some advice. They colour matched the B&Q paint to the Velspar Premium Blend V700 which was recommended to be the best coverage paint and sure to cover the blocker marks. It took a further two coats of this paint to cover the Polycell Stain Blocker. Not everyone has £ upon £ to throw as redecorating, and I was prepared to prep properly to ensure the best job was done on the budget available to me. Had I known it was going to cost me the best part of £50 on paint alone to cover the walls of this little 4.14 square metre room on account of this Polycell product, I’d have taken my chances with the original stains. A very disappointing and frustrating experience.
Depends on where or what you use it on

Used it near a window in the kitchen and I’d say yes it blocks the stain BUT the spray flashes through the emulsion. I’ve done 4 coats of emulsion after spraying and all you can see where I have sprayed. It looks like wet, shiny and greesey

I had a water stain on my living wall and had tried so many products with no success. A family member who is a painter and decorator recommended this and my issue has now completely disappeared! Fantastic stuff!
Very effective stain block
Vintage Kate - 3 years ago
After repairing a ceiling leak from the upstairs bathroom, the downstairs kitchen had to be replastered and painted.
The kitchen walls were still showing patches of damp after one coat of paint but, after spraying the Polycell Stain Block on the wall, the second coat of paint went on like a dream with no bleed through of damp at all.
I was very impressed that it was so easy to apply and so effective.
Definitely saved a lot of time and extra work.
