How do you treat mould on exterior walls before painting?

It’s crucial that mould is removed from exterior walls prior to painting. To remove mould, apply a watered-down soapy solution and gently wash the surface in a circular motion using a soft brush. Make sure to be constantly rinsing off the brush to prohibit any secondary spread an remove all residual traces of mould before paint. For more information go to our Exterior painting page.
