Application of Boracol 400RH will assist in preventing decay by wood destroying fungi, including those causing brown rot, soft rot and will assist in arresting decay already present but not yet far enough advanced to substantially weaken the structure of the wood.
It may be used as a remedial treatment where the timber is being attacked by wood destroying borers such as lyctids and anobiids and termites.
Boracol 400RH is viscous in consistency and can therefore be applied by brush to the surface of the timber to be treated or injected into holes drilled into the wood.
If the surface to be treated is very dry, the penetration of Boracol 400RH will be enhanced by wetting (but not soaking) the surface with water prior to treatment. Boracol 400RH can be applied immediately after the water has absorbed by the surface. This is always necessary when using the high rates of application on timbers with very dry surfaces.
At high rates of application (remedial / insecticide) it may be necessary to apply two coatings with 2 to 3 hours interval between coats. For ease of application via spray method it is recommended that Boracol 200RH be used in place of Boracol 400RH. Consult the Boracol 200RH label for correct application rates.
For the preventative or curative treatment of timber structures the preferred method of application is injection of Boracol 400RH into holes drilled into the wood.
The size, number and location of holes are determined by a survey of the structure to be treated to ensure the correct amount of active ingredient is distributed into the timber to be protected. In order to achieve this optimum loading it is frequently necessary to re-fill the holes. After the holes are filled, they are sealed with a tamper-proof plastic plug, which can be removed at any future time for inspection a replenishment of the reservoir.
Boracol 400RH will absorb into the wood within 24 to 48 hours.
Surfaces exposed to weather / rain are recommended to be sealed after application of Boracol 400RH with a water repellent, paint or other suitable surface sealant. Ensure the surface is dry before application of any sealants. Boracol 400 RH may also be used for the sterilisation of masonry / brickwork / concrete which has been in contact with decayed timber.
The masonry / brickwork / concrete should be dampened down with water prior to application to ensure diffusion of Boracol 400RH into sub surface reservoirs.
