The Cleaning Process
Your wood is then carefully power washed with between 2,000 and 3,000 P.S.I. of water pressure. Power washing essentially removes the top layer of dead wood fibers much the same way sandblasters remove rust from metal. Our technicians are trained to carefully maintain an approximate 45 degree spray angle and stay with the wood grain to avoid excess fraying of the wood surface. If your wood has serious tannin stains, a light solution of oxalic acid and detergent will be applied to brighten wood and help in the cleaning process. If severe fungi, mold and mildew exist, We apply a light anti-fungal chlorine solution to kill organisms which can inhabit deep into the wood fabric. All openings around windows, doors, and eaves are caulked with a silicon sealer if a risk of leakage from power washing exists.
The wood is allowed to dry for 48 hours, at which time the wood must be prepped for staining. The wood is then brushed and sanded to remove any fraying or splintering of the wood.
During this time necessary repairs will be done.
After evaluating the condition of the wood and discussing the individual desires of the client, we formulate the appropriate blend of TWP series 200 and series 500, If the wood is older and porous, we recommend a higher
concentrate TWP series 200 adding more solids to the blend, thus increasing the protection factor. Several sapmles will be put up for your review
The Application Process
The application goal with TWP is to saturate the wood fibers without having the product "puddle" on the surface. After an initial application is made with roller and brush, a second coat is applied approximately an hour later if the wood will accept more product. This process is referred to as, two wet on wet coats.
The plastic is then removed and the post application cleaning process begins. The windows and any metal or painted trim are cleaned; and all debris and materials are removed from sight.
A final walk through is done with the foreman and the client, to assure that all work has been completed to the client's satisfaction.
