Plastering in Bloemhof

A skim coat is touch-dry in a day but needs roughly a week to fully dry before painting; full re-plaster can take several weeks depending on thickness, ventilation and season. Paint too early and you trap moisture, causing peeling. Use a mist coat (diluted emulsion) first.

Skimming is a thin 2-3 mm finish coat applied over existing plaster or plasterboard to give a smooth paintable surface. Full plastering means building up base (browning/bonding) coats plus a finish coat, needed when old plaster is blown, damp-damaged or removed back to brick.

No — plaster over damp fails within months. The moisture source (rising damp, leaking gutter, condensation) must be fixed first, then damaged plaster cut back and replaced, sometimes with a salt-resistant renovation plaster. Any plasterer who skips the cause is selling you a repeat job.

It is one of the messiest trades — expect splatter, dust and high humidity. Empty the room if possible, or centre furniture under sheeting. Floors should be fully covered. Ask whether the quote includes protecting surfaces and cleaning up.

Yes, if the substrate is sound — plasterers key the surface and use bonding agents. But blown (hollow-sounding), crumbling, or damp-stained plaster must come off first. A good plasterer taps the walls during the quote to check; be wary of anyone who doesn't.

Classic rising damp — older homes with failed or missing damp-proof courses wick ground moisture up the brickwork, and salts push the plaster off. Re-plastering alone fails; you need a DPC repair or injection first, then salt-resistant plaster.
