How do you know when to replace plaster?

You can tell if a section of wall needs replastering by pressing the heel of your hand on the wall. If the plaster feels solid, a patch job will usually work. If it feels spongy, it`s best to replaster.

Similarly, you may ask, how long does Plaster last?

Plasterboard takes on average 2-3 days to dry when plastered, whereas backing plaster takes 4-6 days. No matter what material you have used, it is advisable to wait at least a week before painting new plaster. Sometimes it may even take up to a month for the fresh plaster to be completely dry.

Likewise, should I replace plaster with drywall? A: Yes, it's expensive and messy, but your first thought is your best. To do the job properly you should strip all the plaster from the walls, leave the lath in place and cover it with 3/8 -inch drywall. This is also a great time to add insulation to exterior walls.

One may also ask, should I keep old plaster walls?

As long as they're in decent condition (not falling away from the lath in chunks), you may opt to leave them as they are. For many, plaster walls are a big part of an older home's historical charm, and they're well worth keeping intact.

Can I plaster straight onto brick?

Plastering Directly to Brickwork Although uncommon these days, it is sometimes still necessary to plaster directly to old brickwork or blocks. This is more commonly done on small areas of wall where sections of old plaster have come away and is done as a 'patching in' job, rather than over an entire wall.
