The term ‘chalking’ refers to the formation of a white, chalky powder on the surface of the paint film. This condition often occurs as the paint weathers and the binder is slowly degraded by sunshine and moisture, releasing the binder’s hold on the pigment.

Possible Cause
The term ‘chalking’ refers to the formation of a white, chalky powder on the surface of the paint film. Chalky surfaces will cause the paint not to adhere correctly to the surface and will cause premature peeling.
Solution
Remove all loose and flaking paint. Wash down surface with pressure wash to remove all chalky powder, and dirt.
Use Stevensons Bonding Liquid or Stevensons Plaster Primer to prime surface before repainting.
Apply two coats of good quality paint e.g Stevensons Linen Silk or Stevensons Wallkote.
