Polystyrene Tiles - HELP!!!!!!!!!!!!!!!

Postby cambrian481 » Thu Apr 17, 2008 11:23 am

I have removed the poly tiles from the ceiling in my hallway and the stairs. I got the glue off with a steamer and then sanded the ceilings. My husband then put a layer of of pVA/paint mix on the ceilings to seal. Once this was dry we painted the ceilings in question with emulsion......however in places the paint has just congealed, bubbled and dripping. Where have we gone wrong??? and how can we rectify??? Please help.

Simply Build It

Its the PVA - total waste of space in this sort of application. Shouldn't have used it I'm afraid. Clean it all off and start again.

Once you are back to a good plaster surface (provided you haven't sanded the surface layer off that is) gie a mist coat of matt emulsion diluted with about 20% water. Allow to dry then another mist coat but only 10% dilution this time. Finally you can do your top coat.
