Hi I'm still new to plastering and I was wondering how many bags per set should you be putting on ? I knock up a bag and a bit in one bucket which fills the bucket . Put that on and knock up another to top . Is this slow ? I have seen other plasters knock up a bucket to lay on first coat and knock up another but wet, so when they finished first coat theres a bucket ready not stiff but just right for there second coat , anyone else do this ? Whats the best way to knock your stuff up on 2-3 bags a set or even more ? Also when you do put big sets on is it best to put it on as fast as you can , or take a bit more time but keeping it flat as you can ? Thanks any advice will a great help thanks .
