i have painted a wall with vinyl matt that has previously been painted with slik and it now has a cracked finish to it ( sort of like crackle glaze). I have skimmed the complete wall with a fine filler, sanded and re-painted but the same thing has happened again. Can any body please help?
are you sure it was vynil silk and not oil based egg shell if its oil the matt will not stick to it you could try using an acrylic primer crown paints do a good one .the only to be sure of no problem again is to put at least 1000 grade lining paper on make sure you sand the wall well to provide agood surface.its just like hanging good quality wallpaper.
Hi the crazing can happen if you don't thin the emulsion down. Dulux emulsion in particular is terrible for this.
I don't like dulux paints anyway, they are overpriced and made too thick, I use Crown, Brolac or Macphersons. None of these emulsions require thinning down and they cover very well with two coats.
Its better to put on 3 thinner coats than one thick. for strong colours a flash coat is a good idea, this is a slightly thinned layer of emulsion, this acts like a primer, then you can put two coats on top for a solid cover.
