Follow the finish manufacturer's recommendations regarding weather conditions during application. Finishes should not be applied early in the morning if condensation is present or in the evening within two hours of sunset. Always apply finishes according to the manufacturer's recommended spread rate. Finishes applied at the proper spread rate assure optimum film thickness to protect the wood surface from weathering. All new wood should be primed for best performance.
Primers help to provide proper adhesion to the surface.
All edges and ends of the siding should be sealed prior to installation. Check with the coatings manufacturer for recommendations regarding suitable edge sealers for siding that is to be stained. For painted siding, use the same primer that is applied to the face of the siding. Lumber sidings should also be back-primed. Brushing helps work the finish into the surface texture to provide wetting and coating of all surfaces and is especially important on saw- textured sidings.
