Check the instructions on the tile adhesive..chances are your PVA will do more damage than good..though you may need a sealant..

NOOO...to pva...if your tiles are under 250x250mm then you can use a tubbed adhesive(this has the acrylic primer already in it....well a good mfr..bal/weber/ardex/mapei..)

if tiles are over the above size.. then YOU WILL NEED TO PRIME the finish plaster with an acrylic primer from one off the above mfr...bal primer/mapei primer G etc..follow mfr inst for mix ratio...


if its just been a skim coat plaster..give it time to dry/cure before tile fixing...
