Can anyone clear up some queries I have about sand and cement rendering as I hear contrasting opinions. I would like to Render a large block wall, hopefully whilst the weather is nice ;
1 Should I use sharp sand or building sand and to what mix per cement?
2 Do I apply PVA direct to the wall or add it to the mix?
3 To what thickness is the scratch coat applied?
4 To what thickness is the render in total?
5 What does it mean to float off using a wooden float?
6 Do I use mortar plasticiser or Lime to make the mix more pliable?
I have a good idea of the general principles but would like to clear up these points before I start slapping stuff on the walls.
