This is a stupid question but I have to ask ! I’ve seen mention a couple of times of over mixing plaster, can you ? And what does it do ?
A good pal of mine still starts off his mix with a length of 2x2 mate. I personally think he’s nuts. LolOver mixing speeds up the setting of the plaster and can breakdown the particles of plaster which can lead to a multiple of issues. Soon as the plaster is lump free stop the mixer.
