Afternoon all.

Anyone here ever PVA'd plaserboard before skimming it?

The reason I ask is I've always just scrimmed and then skimmed straight onto the board. However, I've a pretty large job later this week (a wall 8.5 metres wide, 3 metres high) and want to do the entire wall in one go without having to break it up into two sections and worrying about getting a good join. I'm therefore wondering if a 5/1 PVA prime followed by a 3/1 PVA coat would slow down the skim going off.

Would it be of any benefit? Woul it be detrimental in any way?

Cheers

Fred
