Quick answers
Our balcony parapet and walls keep peeling. What preparation is needed before repainting them?
Simply painting over a peeling balcony parapet will not hold. All loose paint and crumbly render must be scraped off, the surface repaired and primed, and finished with exterior acrylic paint.
Balcony parapet walls and exterior walls are constantly exposed to rain, balcony washing and strong sun. Once moisture gets behind the paint film, the render softens and the paint lifts in flakes.
On this balcony, the inside face of the parapet had peeled along its length. All blistered paint and crumbly render were scraped back, the surface was repaired and primed, and the parapet was painted crisp white.
The same applies to balcony walls darkened by city grime: once the balcony is cleared and cleaned, the walls are repaired and coated with exterior paint, brightening the view from inside the flat as well.
