Cracking of painted coving

[Fubsy]

Can any body help we have recentyly re done the kitchen which includes a new AGA which produces heat all the time However when i paint the preexisting coving with white emulsion the surface cracks like crackle effect.

I have hand sanded the coving and applied PVA glue however i still get the crackle effect.

Perhaps the glue wasn't watered down enough would this make any difference

Does anybody know how i can get rid of this effect as i want to paint this weekend

many Thanks

Neil

heeelllooo neil

the crazing is an indication that the paint is not sticking
are you shure the surface is free from grease dust

now ive never painted emulsion over pva
but i would have thought pva giving a plastic finnish
wouldnt take emilsion to well
as i say i dont know
