Stain Blocker & Multi-Surface Primer 250ml- Versatile All-Surface Primer for Blocking Stains and Sealing Porous Materials; Optimal for Walls, Ceilings, and Wood

Bought to cover a water stain on ceiling following a leak. Followed instructions and after 2 coats can't see the stain anymore. Also used it on a stain on the ceiling from a child's slime ball that had been stuck to ceiling and left a pink mark and it covered it also. Didn't need a large tin so this size was great.

Works well. Must be left to dry completely before covering with final coat of ceiling paint

Very good but I did go over the top and put 4 coats on the ceiling for a water stain. 2 months in and the stain has not returned. I was expecting a thick paint but this water based paint is just like normal wall paint.

Amazing quality paint. So easy to apply and dries very quickly. Fantastic coverage. No odour. Brilliant

Used this product to cover water stains on an interior ceiling. It took three coats to cover the stain but I was happy in the end.

Water leak in the bathroom ended up on the lounge ceiling leaving a brown water mark. Just one coat of this stain blocker covered the stain then just one coat of Matt Vinyl and you can’t see the stain.

Pleased with the coverage but more than one coat required The stain was not too bad.

Giving my walls a touch up this spring with regular white paint, my patches went all orange and yellow! This Primer paint saved my wall from what looked like a disaster! Would recommend 100%

But almost twice the price of Kilz 3 Premium Interior Exterior. Rustins is made in the United Kingdom. It's extremely thick and dries quickly, so any of it applied has to be smoothed out immediately--if it isn't a hard glob or ridge will develop in seconds. Kilz dries quickly, too, but it's thinner and easier to work with. I bought the Rustins for a bedroom painted an extremely dark blue-green that had the paint slopped on so that the stains weren't originally visible. First I sanded with a Makita 18v jitterbug, then two thin skim coats of plaster to even up the plowed field surface--that's when numerous black stains appeared thru the white plaster. The Rustins was first applied with a roller on the large area that had numerous black stains 1/2 inch diameter and smaller, and on scattered small stains. Some still showed black and had to be coated a second, third and fourth time with a small brush. That's when I knew it was no better than Kilz. The can had a rough life with numerous brutal dents by the time I got it. The lid wasn't fully tapped close and dried flakes were on the lid when opened. A small amount of hard dried paint was in the box.

This product covered water stains perfectly. I would definitely recommend purchasing!
