The Shade Problem in Lynnwood
Lynnwood has the tree cover that newer parts of Pretoria East do not, and that is exactly why the paint behaves differently here. A wall under a mature jacaranda or oak canopy never gets the direct sun that dries it out. In summer, when the rain arrives almost daily for months, those walls stay damp for long stretches, and damp shaded plaster grows things.
The result is the black and green staining that appears on south and south-east elevations across the suburb, usually worst at the bottom of the wall, behind downpipes, and anywhere a gutter overflows. Homeowners often assume the paint has failed. Usually it has not — it is biological growth sitting on top of a coating that is otherwise still sound.
Timber is the other Lynnwood signature. Pergolas, exposed beams, timber window frames and front doors are common on the older homes here, and under a wet canopy they need more attention than the walls do.

Killing Mould Properly Before Any Paint Goes On
This is where most Lynnwood repaints go wrong. A fungicidal additive in the topcoat does not remove existing growth — it slows new growth. If you paint over live mould, the spores sit under the film and the staining comes back through, often within a single wet season.
The sequence that actually works: wash the wall down, apply a proper fungicidal wash or a dilute hypochlorite solution, leave it on the surface for the full dwell time the label specifies rather than rinsing it straight off, then rinse and let the wall dry completely. On a shaded Lynnwood wall in autumn, drying properly can take two or three days — longer than most people expect, and longer than a rushed contractor will allow for.
Then deal with the cause, or you are booking the same job again. Trim branches back off the wall so air can move. Clear and repair the gutters. Redirect downpipes that are discharging against the plaster. Growth is a symptom of a wall that never dries, and paint cannot fix that.
Product Choices for Shaded and Timber-Heavy Homes
- Shaded walls: a premium exterior acrylic with a fungicidal additive, applied after the wall has been treated and dried. The additive is worth paying for here even though it is largely wasted on a sunny elevation
- Sheen level: go one step up from matt on shaded exteriors. A low-sheen or satin film sheds water and dirt better and can actually be washed down, where a dead matt surface holds moisture and grime
- Timber window frames and doors: a penetrating exterior sealer system, built up in three or more thin coats, rather than a thick surface varnish. Varnish forms a skin that cracks and lets water in behind it, and then the whole thing has to come off
- Pergolas and exposed beams: the top faces take all the weather and fail first. Expect to re-coat top surfaces on a shorter cycle than the sides — roughly every two to three years against four or five
- Roof: mossy tiles under a canopy need the same fungicidal treatment as the walls. High-pressure washing an old concrete tile roof strips the surface and shortens its life — low pressure and chemistry, not brute force
- Gutters and fascia: on a treed property these are a genuine part of the paint job, not an afterthought. A blocked gutter is responsible for more wall staining in Lynnwood than any other single cause
Timing Around Wet Walls
The general Pretoria East windows apply — late March to May, and mid-August to mid-October — but in Lynnwood the constraint is not the calendar, it is how long a shaded wall takes to dry after rain.
A sunny wall in this city is touch-dry a few hours after a storm. A south-facing Lynnwood wall under a full canopy can hold moisture for two to three days. That means autumn scheduling here should sit at the later end of the window — late April into May — once the rain has genuinely stopped rather than merely become less frequent.
Practical test before the first coat: press a strip of plastic sheet onto the wall, tape all four edges and leave it a few hours. Condensation under the plastic means the wall is still releasing moisture and is not ready. It costs nothing and it saves an entire elevation.
