Painting brick and render in the Inner West: prep, primer and lifespan
Brick and render hold moisture differently from timber. The wrong system peels. Here is how it is done right.
Why masonry is different
Brick and render are porous and can hold moisture. A paint that traps that moisture blisters and peels. That is why masonry painting uses breathable primers and masonry paint, not a standard wall system.
The preparation and system
- High-pressure clean: remove dirt, algae and loose material.
- Acid wash where needed: to remove efflorescence and stains from brick.
- Breathable masonry primer: to seal the surface without trapping moisture.
- Two coats of masonry acrylic: for a durable, weather-resistant finish.
How long painted brick lasts
Painters in the Inner West say painted brick needs repainting every 10 to 15 years, depending on exposure and preparation. Once brick is painted it is hard to return to bare brick, so decide carefully.
Heritage caution
In heritage conservation areas, painting original face brick is treated as harmful and needs consent from Inner West Council. Always check first. See heritage home painting in the Inner West.
Choosing a painter
Ask which primer and which masonry paint they use, and whether they acid wash. Painters who repaint brick and render in the Inner West follow this sequence.
