kitchen bathroom paint on new plaster

i used this paint watered down as the instructions said (although it didnt really mix well with the water), looked like it went on ok, but after having to chase some cables, ive noticed the paint peels off like masking tape. its just like a film and coming off in huge bits.

can anyone advise as to what went wrong? i am happy to remove it all and start again (comes off so easily with a scraper).

i did wait several weeks before i painted so the plaster had dried.

Was it dilute enough - it's supposed to soak in rather than lie on the surface as yours seems to have done - the whole point of using a dilute coat is to prevent this from happening.

Also, how long ago was the painting done? It does take quite a long time for the paint to harden properly, after it's apparently dried. You might be asking too much of it too soon.

I've also heard that if the plaster has been too well trowelled/polished by the plasterer, it may provide a somewhat shiny non-stick surface, which can benefit from a quick once-over with fine glasspaper to provide a better key for the paint.

It's not the best paint to use for this either. Watered down matt emulsion is excellent for this, and gives a very nice surface to take any type of paint. It's also cheap.

It takes many weeks for paint to reach final strength.
