crumbling wall

[adryley]

I'm trying to put rawlplug in a wall where the plaster crumbles. Each time I try I get a hole that's too big to hold the rawlplug. Any suggestions?

I don't know if it's an approved method, but what worked for me is to apply a silicone damp-proofing treatment (one of those paint-on-yourself wallshield things) first. The silicone held the plaster together very well. Or you can drill a large hole, fill it, then put the rawlplug in that...

There is a new product I found in Homebase called Wet'n'fix - it's impregnated pads you wet and put around the rawlplug before putting in the wall. They set in a few minutes and hold the rawlplug in.
