DESCRIPTION: This is a transparent preservative prepared from Borax which can be used for interior or exterior applications. It seeps quickly into the wood, protecting against fungi and insects. It may be used to prime all types of wood surfaces, even timber with moisture content above 20% or wood in contact with the ground. After treatment, wood becomes brown in colour.


Note: This product does not currently comply with the Australian Standard 2057 “Soil Treatment for Buildings under
construction for protection against Subterranean Termites ". The following test reports have been published:
• CSIRO Australia 1958 - Susceptibility of Termites to boric acid.
• New Zealand Forest Service - Toxicities of some waterborne wood preservatives to wood-destroying fungi.
• It has been approved by the Institute of Building Technology in Berlin as effective against fungi and insects.


USE: Building frameworks, ceilings, log cabins, bee hives, stalls, barns, windows, fence posts, garden furniture, railings, sand boxes etc.


PREPARATION: Wood surfaces must be dry and cleaned of oily and greasy contaminants using BIO Thinner. Previous coatings must be removed.


APPLICATION: Mix 150 grams Borax with one litre warm water (40C). Brush, dip or spray evenly, working it well into the grain. Large or pest infested pieces should be dipped or sprayed. Visible surfaces should be painted with a brush. The second coat can be applied after 24 hours drying time. Exposed timber which is in contact with the ground must be sealed off with a paint or varnish, to prevent rain leaching out the salt. For posts, beams and poles prepare a solution in a drum or trench and soak the timber for 24 hours.
For proper protection use the following quantities:
• Timber thickness less than 40 mm = 300 ml solution p.sqm.
• Timber thickness more than 40 mm = 350 ml solution p.sqm.
• For small holes from borers a 5% solution may be injected into the holes using a syringe

CLEANING: Use water


COVERAGE: 1 Litre covers 7-10 sqm., depending on the absorbency of the timber

INGREDIENTS: Borax concentrate - dissolves in up to 15% in water


PACKAGING: 1 kg, 10 kgs and 25 kgs

PAINTING: Treated timber may be painted when completely dry. Before painting wash off the surplus of Borax on the surface, otherwise surface residue may inhibit paint adhesion or discolour the paint.


PRECAUTION: Keep away from children. All types of exposure are considered to be practically non-harmful. The main effect of exposure is irritation due to the mildly corrosive nature of borate dusts and solutions.

FIRST AID: Skin: Contact with skin may result in mild irritation. Wash contaminated skin with plenty of soap and water.
Eyes: Contamination may result in mild irritation. Irrigate with copious quantities of water for 15 minutes.
Inhalation: Remove victim from exposure.
Ingestion: Thoroughly rinse mouth with water. Give plenty of water to drink and induce vomiting. Seek medical advice if effects persist.


STORAGE AND TRANSPORT: Keep tightly sealed in a cool and dry place. At all times should be stored away from foodstuffs. Not defined as a dangerous good by the Australian Code for the Transport of Dangerous Goods by Road and Rail. The product is a scheduled poison (S5) and must therefore be stored, maintained and used in accordance with the relevant State Poisons Act.
