Soluble Borate Powder

Armor-Guard is concentrated borate powder that is dissolved in water and then applied by brush or spray to bare wood. When other factors prevent the use of Shell-Guard or Shell-Guard RTU, Armor-Guard is the next best preservative to use.


For remedial control of organisms attacking wood, apply 10% aqueous solution of Armor-Guard by brush or spay until the surface is thoroughly wet (approximately a liter of solution per 15 m2). Application may also be made by drilling and then injecting the solution under pressure into sound wood or until run-off is observed from entry/exit holes of infested wood. Alternatively, apply Armor-Guard powder to infested members by drill and injection into galleries or dust generously on wood surfaces and in wall voids at a rate of approximately 50 g per square meter.


Spray or powder/dust applications of Armor-Guard may also be made to wood during construction. Apply solution to all accessible surfaces of bare wood at a rate of approximately one liter per 15 m2 Application should be performed after framing and roofing are in place and before insulation and dry wall are installed. Avoid spaying electrical components. Protect treated wood from excessive rain. End-cuts of wood may also be treated by spray or brush methods listed above, or by 5 minute dipping in Armor-Guard treatment solution
