Boxes into lath and plaster

[Jon Bridges]

Interested to know if anyone has any special techniques for putting back boxes into lath and plaster. Cutting the lath's can be tricky, but also how to attach the box. I generally use a plasterboard box, but if the plaster is thick you cant get the clips behind the lath's, and if they are only supported by the plaster the box will soon fall out, as I found out the other day.

You could try Sikaflex, it sticks like s**t to a blanket but it does take a good while to set. Plywood packing blocks behind to make the correct depth.
