Re-fixing into knackered holes.

If it is brick/block/concrete try using a chemical anchor with a threaded stud in it - it will be stronger than the wall it is fixed to.

Screwfix sell it as do most builders merchants (not usually found in DIY stores)

Fill the holes with car body filler, then skim and re-drill for plugs.

You should gouge out any loose stuff and if clever, where the new fixings are going, and if extremely clever, insert new plugs into body filler as it sets.

Fill the holes with Gripfill and push a rawlplug in before it sets.

My strategy, which has never failed up to now, is to fill the hole with hot melt glue and push in a rawlplug, then, at least the first time I did it, run around yelling with hot melt glue stuck to the end of my finger :-)

I think it works particularly well because the hot glue flows into cavities in the masonary and forms a plug better than other solutions.

Or use the biggest plug that'll fit tightly and fill that with a smaller plug(s)

This is a great idea. Never thought of it, but I'll try it next time. Is it worth saying that he should make sure all the loose dust and bits are cleared out?

Peter Scott

Indeed it would. I completely forgot to mention that :-) I just stick the vacuum cleaner up to it for a second or two.
