How to do it
Rinse and Let Dry
Apply Primer and Paint
If you choose to stain cedar rather than paint it, there's a few things you should know. Staining cedar siding differs from application of paint and other finishes. Stains dry rapidly, and fresh stain applied over dried stain will show lap marks.
First remove any mill glaze (a hard shiny surface on one side of the siding) by sanding. If possible, stain all sides of the siding before installation. Working in tandem with a helper or working alone, stain one length of siding from end to end before moving down to the next board.
If you choose to spray either primer or paint on your shingles, apply the coating evenly and from different angles. Work in sections of about 20 square feet and backbrush the coating immediately so it gets worked into the shingle fibers and the recesses between them.
