Rated 3.9 out of 5 by 17 reviewers.
Rated 2 out of 5 by not as expected I bought this item in readiness for my decorator to use on a newly plastered bathroom ceiling. He applied the product as instructed ~ the final colour of the ceiling was to be white so it was concerning that the sealer dried out to a dark mustard shade. So, when the decorator applied the white paint a few days later, the result was patchy and ultimately it required 4 coats! I have, however, spoken to other trades people who think that diluting paint is just as good for a freshly plastered ceiling. 29 October 2016
Rated 1 out of 5 by Awful Very sticky - I used a brush to apply this as directed and you can still see the brush marks on the wall. Would not recommend think the best way to seal plaster is to use watered down paint and lots of it! 04 July 2012
Rated 4 out of 5 by Scary Stuff! I purchased this to use on my freshly-plastered bathroom ceiling - I didn't want to risk any problems given the cost of the plasterer! I applied as directed to a beautifully pink, smooth ceiling. And ended up with what looked like a patchy, streaky disaster with brush and roller marks all over! Fortunately, application of the white emulsion after the recommended drying time has resulted in a great finish. Phew! But things were scary for a while and the males in my family really did wind me up, telling me I should have used a variety of other things that would have cost less and not resulted in the scary phase. However, I'm hopeful that it does do 'what it says on the tin' and that I've done the best thing for my bathroom! 05 April 2012

Rated 4 out of 5 by blue to clear easy to apply and with it being blue you can see what you are doing it then dries clear so when you paint it ,it doesn't show through 24 February 2011
