TWP WS STAIN SURFACE PREPARATION:

NEW WOOD: It is best to allow new wood 4 to 12 months of natural weathering before finish coat application. After aging, wood should be cleaned with a solution of 1 part household bleach to 1 part water. The bleached surface should be thoroughly rinsed with water; power washed and then allowed to dry a minimum of 48 hours in good drying conditions before finish coat application.

OLD WOOD: Unprotected old wood is typically various shades of gray to black due to mildew and ultraviolet light attack on the wood surface. Old wood should be cleaned with a solution of 1 part household bleach to 1 part water. The bleached surface should be thoroughly rinsed with water; power washed and then allowed to dry a minimum of 48 hours in good drying conditions before finish coat application.

SEALED WOOD: Any previously applied finish must be removed before TWP WS can be applied. Clean the surface with a solution of 1 part household bleach to 1 part water.  Thoroughly rinse the bleached surface with water. Once the surface is bleached and rinsed, remove finish with an appropriate stripper following label instructions and safety precautions, by sanding with 60-80 grit sand paper or by power washing. If sanded, the surface should be thoroughly rinsed with water 2 different days after sanding. Allow wood to dry a minimum of 48 hours in good drying conditions before finish coat application.

CAUTION: Wear rubber gloves, splash goggles, and any other equipment deemed necessary for personal protection when handling bleach. To minimize damage to vegetation, spray with water before, during and after bleaching. Do not allow bleach to come in contact with aluminum windows, doors and mechanical equipment.
