Loss of original timber colour on clear-finished timber weatherboards
Loss of original (new) timber colour on clear-finished timber weatherboards
Causes
Cause
Weathering, UV light exposure
Repair
-
film-forming clear or lightly pigmented coatings are vulnerable to ageing of the underlying timber and loss of coating adhesion under UV light from the sun
-
some timber producers do not recommend clear finishes for timber elements fully exposed to sun and weather
-
recoating of clear or pigmented film-forming coatings is likely to be required every 6 months–2 years
-
scrape or sand off the existing coating to give a clean, as-new timber surface. Recoating with the same type of product will restore appearance but frequent recoating will be required.
