Good product

It takes two or three coats to cover a deep stain, but very easy to use, don’t forget mask and cover items in room as the fine spray floats through the air. It is easy to clean as I found out after forgetting to do the above

Do not use!

I bought a can to cover over a drawing on a white wall. It was virtually useless and I still ended up having to apply lots of coats of white. Just tried to spray on a damp stain, and agin the stain has come through despite applying three coats of stain block. I’ll have to get some more stain block from another company. Would not recommend at all!

Brilliant works well

Covers up water marks really well. Use every time I get a job of a water stained wall or ceiling. Needs good ventilation while spraying I find. A tip shake can really well before use.

Waste of time and money

Absolutely dreadful stuff. Bought to cover some stains on the ceiling that were leftover from a leak we had. Used almost a whole can on a couple of spots and still it didn't cover. Entered up paying out a lot more for some brilliant stuff. Don't waste your money

BRILLIANT STUFF

All it needs is a quick spary and it blocks the stain and BLENDS with existing paintwork. That's all - and you can't even tell where the stain has been! Why is this product difficult to get hold off - even at B&Q?
