The paint applied to a section of timber cladding (outdoor) has failed to adhere to the to the timber as evidenced in the photos below:
The paint was applied in the same year as the timber was installed, which is approximately 2 years ago. The peeling/flaking stated appearing within a year and exhibits worst conditions on south/south-westerly elevations (where the sun shines most in this side of the world).
The timber is reportedly Douglas Fir (unclear if it was treated or untreated), and the paint is Bedec Barn Paint (Acrylic based), which appears to have good reviews.
I do not have the history of how the paint was applied (how many layers, whether any primer was applied, whether it was brush painted or other,...).
The photos above show:
- different degrees of peeling/flaking (not uniform across all planks. There appears to be a correlation with the wood grain and the level of peeling
- Peeling follows grain pattern
- Same as above (no peeling between grains)
- Same as above
Any suggestions on:
- what the cause(s) of the peeling/flaking may be?
- how to remedy?
- what further questions to ask from the contractors who conducted the work that would help establish the above?
- any tests you would suggest would help with the above?
