Just wondering about correct procedure when making good chased in bathroom hot and cold copper pipes and plastic waste pipes. Is a coat of bonding, skrim joints and a two coat skim sufficient? Ty liam.

hi Liam,sorry for the stupid answers so far,use denzo tape over the pipes ,fill the chase with whatever material is on the wall and skim it or easi fill it then
And what's den so tape for ? It's been done for decades under floors and in walls, theories all you like but your answer is stupid like mine tooCopper pipe has a linear expansion coefficient of 0.017 mm per metre/per degree. So a short run of say two metres with water at forty degrees temp rise will give you 1.5mm. So every time the hot water pipe has flow through it, and every time it stops and cools it will expand and contract. That doesn't allow for the radius of any covered bends opening and closing, nor does it take account of the pipe being clipped before or after the run through the wall, both of which will increase the movement.
I'm not a plasterer though, so I don't know what skims like for it's ability to flex and stretch. I'll take a guess though and say it doesn't.
So there are stupid answers, but not the ones recommending allowing the pipes to move without being embedded in plaster. :RpS_lol:
