Hi, alright guys. I'm fairly new to Plastering, I'm doin an adult City & Guilds course. I'm picking up the skills really well, but the problem I have is that the tutors dont explain the theory behind whats happening, they just tell us what to do next.
My main brain puzzler is the whole suction thing as they mentioned these words without properly explaining it. I rendered up a wall, they told me to PVA it(and showed me how) and then to skim it, but never actually explained WHY I had to PVA it, what it is trying to achieve and when to use PVA and when not to use it.( i know its to help the plaster stick to the wall but thats it)
Thanks for any help guys
