Having got the new window in and ripped out a 10 tonne skip full of showers,
loos, sinks etc I'm back to a bare shell and ready to start the studwork on
my shower room project (sigh)...
A bit of digging has turned up timbers on 16" centres on 2 of the walls but
the other two are rough stone which has been plastered directly onto. The
plaster is the "old type" (still don't know its name), ie. turns to loose
sand as soons as the surface is broken.
Normally I'd put a two inch hole (deep!) in it stick in a No.10 plug and
screw through the timber (smothered with gripfill) and fix with a 3.5"
screw. Repeating every 400mm. Its a bit of a pain though and you invariably
"lose" a few fixing points. I usually end up emptying half a tube of
gripfill into the holes are screwing straight into it the next morning.
I need a quick, simple and effective way of fixing lengths of CLS to these
walls. Has anyone else got any bright ideas other than above?
