Stain block paint (Read 7069 times)

jimcam GDPR opt-out	Stain block paint Jan 22^nd, 2008, 6:48pm I've used some stain block paint from Wickes to cover some marks on some walls (e.g. black plastic scrape marks). I've put three coats of emulsion over these stain block paint patches now but they are still shining though. Any ideas please?!

I did sand the stain block lightly before applying the first coat of emulsion but I was thinking if I did it now I'd just sand off the emulsion on top and get down to the b!$&dy stain block again. I wish I'd never used the stuff.

In the end I gave the whole ceiling a thin coat of stain block and then emulsioned and it was fine.
