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.
