Symptoms
The coating adheres insufficiently to the
substrate or previous coats.
Cause
- Unsuitable primer applied
- Wrong product
- Damp substrate during painting
- Contaminated substrate (not
cleaned or degreased)
- Weathered timber not removed
before coating
- Previous Coating Unstable
Solution
Coating layers that are not sound should be removed.
Substrate problem should be addressed (cleaning, degreasing, sanding etc.). Apply a new, suitable coating system.
