Can someone here please finalise this topic once and for all. On my course I was told never use PVA with rendering, just dampen with water... on the other hand I hear experienced plasteres saying they have been using PVA for rendering for years and no problems. i thought that PVA creates a skin therefore the render would crack and eventually fall off the wall. On a tub of PVA it states not to be used externally? Also There is a training company called Gold trowel and they have a load of DVD's on plastering, rendering etc and it shows the guy on there PVAing outside houses and then rendering them and before pebble dashing also .... so
What is the story here...
Can PVA be used on external rendering?
can PVA be used in internal (ext wall) rendering?
