Dilute Borotreat 10P Powder 1:9 with clean tap water to give a 10% active working solution. In some cases as a superficial treatment against Dry Rot (Anobium Punctatum) apply a 4% solution at 4m²/litre.

Borotreat 10P is supplied in convenient pack sizes of 0.5kg and 2.5kg bags to make 5 Litres or 25 Litres of diluted product respectively.

Use an oversized bucket or container with the appropriate volume of clean tap water and add the corresponding amount of powder concentrate.

Mix the powder into the water with a suitable paddle during addition and continue until it has completely dissolved. Use warm water if possible to help the powder to dissolve.

The working solution of Borotreat 10P can be applied by brush, spray or injection.

  1. Clean all wooden surfaces using a brush or vacuum cleaner.

  2. Cover electrical installations, water tanks, stored goods and isolate adjacent areas not requiring treatment.

  3. Lift floorboards as required and clean out debris.

  4. Treat all accessible areas with the working solution of Borotreat 10P using brush or spray.

  5. Under normal circumstances one coat will be sufficient but ensure that all accessible wood surfaces are thoroughly wetted out. Any surfaces that absorb solution rapidly should be sprayed again at the time.

  6. Apply a second coat after one to eight hours where there is a severe fungal attack or woodworm infestation.

Note: Borotreat 10P needs to be applied to absorbent timber. Any paint, varnish or stain must be removed prior to application. Polished surfaces must be cleaned back to bare timber.
