Boron is a naturally occurring mineral with a long history of use for the prevention of dry rot and wet rot as well as woodworm treatment. Our ProBor 20.1 Gel is ideal for the treatment of larger dimension timbers. It is also effective against wood-boring insects and is particularly useful when treating infestations of Deathwatch Beetle.

The high level of active ingredient in ProBor 20.1 Gel, combined with its gel formulation, provide excellent penetration into timber – particularly damp timbers which are vulnerable to fungal attack (dry rot and wet rot). This also makes it ideal as a woodworm killer.

ProBor 20.1 Gel is designed to be applied by brush directly to the surface of the timber. The application should resemble a thick coating of gloss paint. Depending on the density of the timber, it can take several days for the ProBor 20.1 Gel to soak into the timber.

For effective results, wood should be bare and clean. ProBor 20.1 Gel will not penetrate through paint, varnish, or other treatments which seal the surface of the timber. Such coatings must therefore be removed prior to treatment. Please note that even though this product is described as a gel the consistency isย more liquid and can be poured.

  • Dual purpose active ingredient is effective against insect attack and fungal decay.
  • Excellent penetration.
  • High level of active ingredient, gel formulation, and boron active ingredient combine to provide excellent penetration into timber.
  • Low odour formulation.
  • High strength: Up to 20-times more active ingredient than some conventional paste formulations 5L container.
