Dulux Flexicover on new plaster

I have just painted a newly plastered ceiling with some Dulux Flexicover that I had knocking about. The plaster had been drying for about a month and I diluted it first in lieu of using plaster sealer. However was about to put a second coat on (undiluted) and noticed a small nip which I took of with my fingernail and some of the paint peeled off. It appears then that the flexicover has not adhered well to the plaster. Any advice before I try putting another coat on. I guess I should have splashed out on the plaster sealer?

Cheers Mark

You going to have problems with the cieling forever. As Dulux Flexicover MUST have an Dulux Plaster Sealer applied prior to applying
Dulux Flexicover. If you can, then peel off all the Dulux Flexicover.

OK I will see how easy it comes off.

Thanks

Good luck.........................................
