Hi all,
Just wondering if anyone knows the answer to this.
I have silicon sealed round the windows and expansion joints of 3 houses I have built and rendered in monorex.
Round windows is stop beaded where ingoe/reveal meets window (which is alu clad windows) with pvc beads. Anyway a while later and silicon has kind of come away and on expansions it has come away from stop bead and or window too.
Reason I ask is I have mainly used sand/cement with metal beads in the past and this has never been a problem. Also render has been left a while before silconing so it wasnt as if it was dusty from scapings etc as rain has given a good wash.
It was just general purpose white silicon same stuff I have always used. Has anyone else found this problem or am I not using correct silicon because beads are plastic and alu clad windows?
All the best,
Ben
