Performance Data and Treatment Analysis
PERMA-WOOD® How This Product Works:
PERMA-WOOD’s solution penetrates the cellular structure of green or kiln dried timber and wood media derivatives such as OSB and particle board. PERMA-WOOD 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.
PERMA-WOOD 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. PERMA-WOOD treated wood fibers resist efforts of all cellulose moisture borne fungal and decay organisms. PERMA-WOOD 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 PERMA-WOOD. 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:
Always, WET ALL TREATMENT AREAS WITH WATER prior to treatment and brush off. Then APPLY 3 applications in succession, wet on wet on maximum work areas of 100sf at a time.
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. PERMA-WOOD® will 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 PERMA-WOOD® wood preservatives. Minimal exposure is required as there is no cellular rejection of foreign objects as with aqueous penetrates. Resistance is minimal 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 PERMA-WOOD solution. Stack time of 1 hour is suggested, however not required as Petri-Wood 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.
CLEAN UP and STORAGE: Simply rinse with water. Replace cover tightly and store in an area free from any open flame. The product has a perpetual shelf life and will always be ready for use on the next project.
