SWCO WOOD PRESERVATIVE, a "Chemical Free Wood Preservative Solution"
Contains Cedarwood Oil Extracts and Silicone

Patio Deck

This dynamic product is the advancement of a Prior Art, solvent based wood treatment, used in the early years of the Twentieth Century and discontinued with the onset of the USA- FIFRA registration issues of the Mid Fifties. Combining Cedar Oil, specialty silicone binder, and with the use of a hydrocarbon carrier, created a next generation solvent based wood preservative utilizing politically correct Green components, the basis of this dynamic product.

The process theory of SWCO Wood Preservative is simple. The introduction of a highly penetrating natural solvent cross-linked with Cedar Oil and Silicone to the wood cellular structure succeeds in the closing and drying of the Hydrogen tails of the Hydroxyl Molecular group found in wood media. The closure of the molecule chain eliminates the opportunity of the media to harbor moisture content either in airborne (humidity) or liquid form. This results in dimensional stability, water resistance and pest control. Penetration with the proprietary hydrocarbon solvent displaces existing moisture content in the wood which results in Kiln-less Drying, an instant evacuation and exodus of H2o compounds from the media. Unlike aqueous treatments that are subject to entry and exit by moisture and the continuous leaching of toxins, water can never displace a solvent carrier from its impregnation to wood cellular. After entry to the wood through the vascular feeding system, (summer sap ring) and migration to the adjoining sap wood, (winter sapwood ring) the annular growth rings are sealed using the trees own resins as a catalyst that forms a waxy like substance in the media cellular structure. This enhancement mirrors that of internal gluing or the addition of steel plates to the wood, strengthening the composition and limiting the flexibility of the wood.

The scientific data relating to SWCO Wood Preservative claims are published in six patents filed Nationally and Internationally on the 17th day of December, 2004. SWCO Wood Preservative can be used as a wood preservative on closed cell woods including but not limited to Black Spruce. SWCO Wood Preservative is effective in treating all types of Hardwoods and Softwoods.

Performance Data and Treatment Analysis

How This Product Works:

SWCO Wood Preservative solution penetrates the cellular structure of green or kiln dried timber and wood media derivatives such as OSB and particle board. SWCO Wood Preservative proprietary non VOC solvents cross linked to specially refined red cedar wood oil turpenes and siloxene synergist, displace moisture while entering all wood structure through their vascular system.

SWCO Wood Preservative carriers deliver the antimicrobial and termiticidal agents to the wood cell structure where it is encapsulated and solidified by permeable silicone molecules. Natural wood oils are transformed to a wax-like consistency similar to glue which mirrors the effect of an internal adhesive increasing the solidity of the treated product. SWCO Wood Preservative treated wood fibers resist efforts of all cellulose consuming insects and moisture borne fungal and decay organisms. SWCO Wood Preservative treatments result in water resistant and dimensionally controlled building material for above ground and subterranean construction. Paint or stain ready in 72 hours. There is no offensive odor or transferable residue associated with SWCO Wood Preservative. All components are FDA, GRAS and EPA 25b list approved as minimum risk pesticides authorized by the Food Quality Protection Act of 1996.

How To Use This Product on Dry and Green Wood:

Brush – Apply liberally from both sides and ends. Keep the surface soaked or wet until absorption reaches the level of penetration desired.

Roller – Apply with heavy knap roller keeping all surface area wet until absorption reaches the degree of penetration desired.

Spray or Airless – Apply repeatedly with heavy coats to point of run off. Stacked lumber should be separated with slats between layers. Spray ends and all surfaces until absorption reaches the degree of penetration desired.

Submersion – The most desired method to treat green and wet material for drying or preserving structural lumber, plywood sheet products, oriented strand board, particle board, rail road ties, fencing material and wood flooring products. The use of masonry mud boxes, stock tanks and open barrels where total submersion from one or both ends is desirable. Treated material can be reversed for full coverage. Horizontal treatments require weight to offset buoyancy issues. Submersion times from 15 minutes to 1 hour are recommended as seen on the chart below. Excess submersion may or may not enhance performance however, is never detrimental to the objective. Does not compromise pre-treated surfaces such as hardwood floor or laminates.

Pressure Treatment – Standard pressure over vacuum or isolated pressure treatment protocol can be used with SWCO Wood Preservative wood preservatives. Minimal exposure is required as there is no cellular rejection of foreign objects as with aqueous penetrates. Resistance is minimum to the highly acute cedar oil turpene extracts and silicone compound. Elapsed vessel time is suggested at 15 minutes. Normal pressure treatment protocol should be calculated subject to equipment manufacturers’ instructions.

Evacuation – Drip dry time of 3 to 5 minutes is recommended for salvage of unused SWCO Wood Preservative solution. Stack time of 1 hour is suggested, however not required as SWCO Wood Preservative cures are triggered by catalytic reactions from oxygen.

Desired Penetration – Total dimensional control is obtained with complete penetration. Insect, fungal and decay control can be achieved with partial penetration. Construction window treatments of minimum penetration will provide water and surface mold resistance for up to 90 days. Southwestern Cedar Oil suggests a minimum of 10 minutes for satisfactory results of all treatment objectives.
