TWP WS Series Water-based Stains

TWP Water Series Total Wood Protectant

TWP Stain is best known for offering superior oil-based wood stain and preservative products. Now they have taken matters one step further – the first ever TWP non-film forming water-based wood stain. TWP WS Series utilizes a unique combination of chemicals that enhance the natural beauty and warmth of the wood. TWP Series then penetrates deeply into the wood fibers without leaving surface film build. This helps the stain to highlight its existing grain patterns with amazing clarity and a warm feeling.

Sealed Wood Any previously applied finish must be removed before TWP WS can be applied. Remove any existing finish with Exterior Wood Stain Stripper.  Afterwards clean the surface of the wood with a solution of Oxygenated Bleach Wood Cleaner with a minimum dry time of 48 hours.  It is important to remove all remnants of the existing finish as this product will be unable to penetrate otherwise.

Wood Stain, Many Benefits

TWP Series contains water repellents engineered specifically to inhibit the damage caused to wood by water absorption. It further offers a band of carefully selected mildewcides to help inhibit the growth of mildew on the surface of the stain. Loaded with special UV absorbing pigments any color (except clear) work to inhibit unsightly graying caused by the radiative effect of the sun. The semi-transparent properties of TWP Series allow the wood grain and color to show right through.

Wood Staining Considerations

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 Oxygenated Bleach Wood Cleaner with a minimum dry time of 48 hours.

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 Oxygenated Bleach Wood Cleaner with a minimum dry time of 48 hours.

Application Notes

TWP WS Series is a penetrating system and is not designed to build a film. Only apply to a properly prepared, clean, dry and absorbent wood substrate. Optimum application is when temperature is in the 50-85°F range. Do not apply if rain is expected within 48 hours.  For best results we recommend brush application although you can use an applicator pad, roller or low pressure sprayer at your discretion.

Make sure to only apply as much material as the wood can readily absorb. On horizontal surfaces apply an initial coat at 300 – 400 sq ft per gallon.  Coat boards lengthwise maintaining a wet edge to avoid lap marks. Allow material to penetrate 10 – 15 minutes and then apply a second coat at 400 – 500 sq ft per gallon. 

Typically, a two-coat application is adequate, but wood porosity may dictate the use of more or less TWP WS Series.  Do not allow material to pool or puddle and remove any liquid material that remains on the wood surface 10-15 minutes after application.  TWP WS should dry uniformly flat with no glossy areas, so excessive TWP WS that does not penetrate and is not removed from the surface will often leave a shiny film behind.
