Problem Solving - Chalking / Erosion

Cause:

The cause of this problem is due to applying water borne paints in temperatures below 5 degrees centigrade.  But don't forget that some exterior paints are designed to chalk as a self cleaning mechanism, so always check the product data sheet before diagnosing this issue.

 

Solution:

Apply Stabilising Solution or Alkali Resting Sealer before recoating.
