What happens if you don't pva before plastering
Why do you need to use pva first?
Expert Trade Answers
"The plaster will not bond to the surface properly if it is not primed (pva/sbr/blue grit etc)
In some cases it will dry as soon as you apply the plaster as the surface will take all the moisture from the plaster"
