Formation of chalk-like dust on the surface of the paint.

Reasons:

• Use of low quality paint
• Use of paint unsuitable for external surfaces

Solution:

• With a brush, remove as much of the dust as you can.
• Scrub the surface and clean it.
• After drying check if there is still dust and if so then use ER-LAC’s high quality primer that is suitable for your surface.
• Then repaint the surface with one of ER-LAC’s paints, which are of high quality and will not present chalking problems.
