Stucco – chalking paint

Cause

Weathering, UV light exposure – chalking will be more visible with darker colours

Repair

  • wash the surface with soapy water or a proprietary cleaner and a soft brush to remove all dirt and grease. Allow to dry thoroughly, then paint with a minimum two coats of acrylic paint. Choose a product designed for masonry or stucco – these can usually be brushed into small (less than 1 mm wide) cracks to help weathertightness

  • select paint of a lighter colour where possible – darker colours can make chalking more visible.
