CHARACTERISTICS OF SUBSTRATE

Treated pine is usually Pinus Radiata that has been pressure treated or dipped in treatment solutions to increase its resistance to insect attack and decay resistance. It most important to correctly identify which treatment has been used on the timber. Treated pine may be CCA (Copper/Chrome/Arsenate) Seasoned-Kiln Dried or Wet, Unseasoned: or LOSP (Light Organic Solvent Preservative).

LOSP Treatment contains wax and other additives. The residual wax on the timber surface can create problems with water based paints adhering properly and may impede drying of solvent based paints. Water based systems should be used over CCA treated pine after it has air dried for at least seven days for Seasoned-Kiln Dried timber and twenty eight days for Wet Unseasoned timber. LOSP Treated timber should be primed with a solvent based primer. Pre-primed LOSP Treated timber should be washed with a detergent solution, rinsed and allowed to dry prior to painting to avoid potential inter-coat adhesion difficulties.

SURFACE PREPARATION

Ensure surfaces are clean, dry and free from contamination. If sanding is required appropriate personal safety equipment should be worn to avoid inhalation of the treated timber dust.

ADDITIONAL INFORMATION

Drying times are approximate at 25° C and 50% relative humidity. Allow longer drying times under cool, moist or low air movement conditions. Spreading rates will vary from the quoted theoretical rates depending on application methods and surrounding conditions.
Do not paint if temperatures are below 10°C or likely to fall below 10°C during drying period
