Stain Blocker & Multi-Surface Primer 250ml

Used this product to keep damp patch inside away, under the window sill, which is the usual culprit, the reading went down from high to low after 3 coats, so pleased with this product! Emulsion covered over very well!

Good value for money. Coats well, may need a couple of coats, reasonable finish

Just the right size. not used yet but will in the future.

Used it on kitchen doors that I had taken the plastic off of. It covered all the black writing that was on the mdf doors.

Initial coverage was good but not long before discolouring was showing through, even after three coats.

Works as it should. Two boats stopped my water stain on the ceiling coming back through

Works very well, 2 coats recommended and easy to apply.

Brilliant product. I had a leak through my ceiling leaving horrid brown water marks. It wasn't a large area so I didn't need a massive tin of paint to cover it. This 250 ml was just the job. And what's more, there was absolutely no odour to it. I can't stand the smell of paint usually but this had no smell. Went on easily. Put on two coats and it's all ready to paint. (I've since painted over it and it looks great)

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!
