Plastering

PLASTERING

DIY plastering any large area is far better done in two stages, removing all the old plaster before starting new plastering work. Although time consuming, this makes a much better job because you are not trying to remove old plaster while working within the time limits imposed by waiting for plaster to set or completing any refinishing, which quickly becomes haphazard, hasty and ultimately a poorer job.

Plasterboard can be repaired using hardboard. A clever way to do this is to cut a shape of hardboard just larger than the hole to be repaired in such a way that a corner can be used to lead through the hole and the hardboard slid through, using string tied through a central hole in the hardboard and the edges of the hardboard coated in glue. The string can then be used to pull the hardboard up tight to the hole, held until it sticks and then the recess re-plastered.

Plaster sets much more quickly by mixing it with warm water.

The most effective way to repair a damaged corner is to reinforce it with metal angle beading which can be cut using a hacksaw and snips. The beading lends itself to replastering over it and is strong. Ensure it is vertical using a spirit level before plastering over it.

Emergency repairs for small holes can be made by filling them quickly using toothpaste. Let it dry before proceeding to coat it with anything else.
