I've repaired a couple of 'blown' patches on my wall and have done the base coat with sand/cement mix which is now drying out. How/Where do I get the white cement for the top coat to tie in with existing 'dash? Does it come as a complete mix or do I need to mix with sand and do I add PVA to the top coat mix as well?
This is my first attempt at anything like this so...be gentle with me!!
