Opaque Finish
Paint
Paint provides the most surface protection against
weathering and wetting by water while providing
color and concealing some of the wood's characteristics.
Although paint can reduce wood's absorption of
water, paint itself is not a preservative.
Alkyd oil-based primers usually offer the best
shield against discoloration by water-soluble
extractives. Latex paint, particularly 100% acrylic
formulations, remain more flexible with age and
are better able to accommodate dimensional changes
by stretching and shrinking with the wood.
