ProBor 50 Wood Preservative Paste

ProBor 50 is a ready-for-use wood preservative paste based on boron, a naturally occurring mineral with a long history of use. It is supplied in a 310 ml cartridge for use with a standard mastic gun. ProBor 50 is designed to be injected into timber. It can also be applied to the surface of timber, although it should be noted that a white deposit will be left.

ProBor 50 is commonly used as a wood preservative when treating large dimension timbers. It is injected into timber via pre-drilled holes, thus ensuring complete distribution of the active ingredient deep within the wood. In general 10 mm holes spaced no more than 150 mm apart are recommended. The number of holes should be adjusted to give a product loading of 5.9 litres per cubic metre.

Other common areas of application include the treatment of joist ends and wooden window frames.
