Repainting Older Plastered Homes in Wolseley

A good portion of Wolseley's housing stock is solid-wall construction with older plaster rather than modern cavity brickwork. Those walls move seasonally and they need to let moisture pass through them. Treat one like a modern wall and seal it under a film-forming coating, and the moisture that used to evaporate away now has nowhere to go, so it collects behind the paint and pushes the plaster face off the wall.

If you have inherited a house where someone applied a plastic-type paint or a thick waterproofing coat to solid walls, you will see it as blistering, bubbling, and hollow-sounding patches when you tap. Fixing that properly means stripping back to a sound substrate, not applying another coat over the top. Budget the plaster repair as its own line item, because it is the single most commonly underquoted part of a job like this.

On an older home the repair figure is genuinely unknown until the loose material comes off, so expect a provisional quantity rather than a fixed number. The fair way to handle it is an agreed rate per metre or per square metre, measured on completion. Be wary of anyone giving a firm plaster repair price without having tapped the walls.

Sequencing Repairs and Painting Through the Year

On an older house the calendar has two stages, and running them together is what causes problems.

  • Plaster repairs need curing time before paint. Allow about seven days for patches and considerably longer for larger areas, so plan repairs for late winter and the painting for spring.
  • September to November and March to April are the two good exterior painting windows.
  • Wolseley runs colder overnight than Worcester, so from June to August drying stalls between coats and exterior work becomes unproductive.
  • New plaster should not be painted until it has cured and its surface alkalinity has settled, and it then needs an alkali-resistant primer regardless of how long you waited.
  • Do not start exterior work with rain forecast within 48 hours. Fresh acrylic that gets rained on before it sets will show washing streaks that cannot be polished out.
  • Interior work is comfortable year-round, and winter is a sensible time to do it if the exterior is waiting on repairs.

Choosing Between Breathable and Standard Paint

The decision hinges on how the wall is built, and getting it wrong is expensive to reverse.

  • Older solid or lime-plastered walls: a breathable masonry paint or a mineral silicate coating. These bond into the substrate and let vapour move through, which is exactly what a solid wall needs.
  • Modern plaster on cavity brickwork: a standard 100% acrylic exterior is entirely appropriate and costs less, so there is no reason to specify a mineral system on a newer section.
  • Many Wolseley houses are a mix of both, with an older core and a newer addition. Those sections should be specified separately rather than blanket-coated with one product.
  • Never use an interior PVA outdoors, and never use a waterproofing membrane as a general wall paint on a solid wall. Both are common shortcuts and both end in stripping work later.
  • Timber casement and sash windows: strip the loose material, prime bare timber with a proper wood primer, then two coats of water-based enamel. Check for rot in the bottom rails before painting, since paint over soft timber simply hides the problem.
  • Interiors: acrylic PVA on ceilings, a low-sheen on walls, and water-based enamel on skirtings and door frames.

Wolseley Painting Questions

How do I know if my walls need a breathable paint?
Age and construction are the main clues. If the walls are solid rather than cavity, if the plaster is soft and sandy rather than hard and cement-rich, or if previous coatings have blistered off in sheets, the wall needs to breathe. A quick check is to tap along the wall: hollow patches mean the plaster face has separated, which is usually moisture trapped behind a sealing coat.
Why is my paint bubbling and lifting off in patches?
Nearly always moisture behind the film. Either the wall is damp and the coating is not breathable, or the previous coat was applied over a dusty or damp surface and never bonded. Painting over it again will produce the same result within a season.
What does plaster repair cost?
Around R190 to R360 per linear metre for cracks, and R280 to R520 per square metre where the face has blown and needs replastering. The honest answer is that the quantity cannot be known until the loose material comes off, so agree the rate rather than a lump sum.
Can you paint over old limewash?
Not with a standard acrylic. It will not bond and it seals a wall that was designed to breathe. Either recoat with limewash or a mineral paint, or strip back, which is labour-intensive. The cheaper and more durable route on these walls is usually to stay with a compatible mineral system.
How long must new plaster cure before painting?
Around seven days for small patches and closer to a month for a full skim, and then an alkali-resistant primer before any finish coat. Rushing this is the most common reason new work shows patchy sheen and early flaking.
