Is there an approved method for attaching sinks, skirting, etc to dot
and dab walls. We have just had an extension added where the breeze
block is made of a bubbled gray breeze block material, wonderfully
light and easy to carve. I consider myself an expert at attaching to
plasterboard on timber frames as I have lived in houses of that
constrction for a number of years, however this new system is baffling
me. I ended up attaching the wooden, i.e. slightly warped, skirting to
the walls using 3" nails and two rawplugs per hole. It works but seems
totally over the top using No 10 screws for this. Similarly I am now
trying to attach a sink to a wall. The screw bolts provided are long
enough fo normal applications but at the moment the chunky rawplug is
just spinning in plaster board, air and soft breeze block. Any
suggestions please, but not including butterfly clamps, expanding
rawplugs etc because they won't work when the air gap is about 15mm.

Cheers

Neil
