Best Way to Apply TWP 100 and 1500 Series Wood Decking Stains
It is best to first measure the wood surface of your staining project. Do not forget to include steps, railings and spindles if you are staining a deck and double the footage of a fence if staining both sides. On average TWP covers approximately 150-300 sq. ft. per gallon. The newer the wood the less stain it will take. Older wood is more porous and will absorb more stain.
Prior to applying any TWP stain be sure the surface is free of dirt, grime, mildew or any old coatings. Use a wood cleaner when no old failed coatings are present. If an old coating is to be removed use a wood stain stripper instead. Allow the wood to dry for 48 hours after cleaning.
The best way to apply TWP is with a brush, roller, stain pad, pump or airless sprayer. Be sure to mix the stain well prior to opening. Use protective gloves and safety glasses and cover any plants, landscaping, concrete or windows you do not want to get stain on. Apply a light coat on one or two boards at a time or in a small section. It is best to work from one end of a board to the other then move on to the next board. This will help reduce overlap marks.
If one coat soaks in fairly quickly a second coat may be applied. A second “wet on wet” coat should be applied within 30 minutes of the first coat. Be cautions of over applying TWP Stain. If excess puddles of wet stain remain after a reasonable amount of time and or not being absorbed do not allow the stain to dry. Wipe away the excess with a clean stain rag or back brush the stain to blend it in. Leaving excess stain on the surface to dry will result in an unappealing shiny finish.
