How to use

Prep Be sure surface is free of all dirt, mildew stains, loose wood fibers and other foreign matter. In order to be effective, a stain must be able to penetrate. Surfaces must be sound and may be dry or damp. If damp, the wood should be free of puddles and not feel wet. Prepare previously stained or weathered surfaces with Valspar® Wood Cleaner or Valspar® All-In-One Wood Prep. On untreated weathered surfaces, it is best to pressure wash, but at minimum, scrubbing with a stiff bristle brush and rinsing with a garden hose should be done to completely remove all loose wood fibers. Sanding is best to remove any loose wood fibers.
Application Apply with nylon or polyester brushes, stain pads or professional spray equipment. When spraying, always back-brush immediately. To ensure desired appearance and proper drying time, always finish a small test area before proceeding. Do not over apply. Shake and stir thoroughly before and during use. If project requires more than 1 container, blend all containers together to ensure uniformity. Apply to small sections at a time (1–3 boards); start at one edge of the board and work end-to-end, following through to the end of the boards to avoid lap marks. A one-coat application is recommended. DO NOT APPLY 2 COATS.
