BORON RODS - the rods dissolve inside damp wood to kill and prevent Insect, Wet Rot and Dry Rot attack

'Boron Rods' are part of a range of Boron based preservatives and are often used inside wood together with Boron Paste, because these two products dissolve at different rates according to moisture content.

BORON RODS - solid rods for embedding dissolving Boron inside holes in wood

These high strength solid Boron rods are used to protect timbers which are constantly or occasionally damp: external joinery, wall plates, embedded beam ends, posts etc. They can also be used in conjunction with BORON ULTRA 78 paste, to act as a long term reservoir (Standard Boron Rod Sizes - 8mm x 24mm and 8mm x 65mm).

BORON ULTRA 78 PASTE - companion product to be injected inside holes in wood

A unique 5% and 40% paste using a special blend of technical grade glycols as carriers. It can be injected into timber, with the advantage of supplying a highly concentrated mobile preservative which will spread even at low moisture content levels. Simple to apply with a standard skeleton gun; more effective to use because of the higher available level of active content, which allows the use of smaller (8mm, rather than 10mm) and/or fewer drill holes.

Benefits of Boron Rods and Boron Pastes as part of a wood preservation job

  • No hazard warnings for normal use
  • Have ultra low toxicity - about the same as Table Salt
  • Kill only wood boring insects and rots - not spiders, birds or bats
  • Have no odour - they leave no smell behind
  • Do not evaporate - the rods dissolve slowly in the wood
  • Are non-flammable - the Boron oxide that they produce as they dissolve is actually a Flame Retardant

Optional Boron Rod Products:

Angled Plugs for Posts and Poles

Augers for drilling 10mm or 13mm holes

Puffer Pump for blowing wood dust out of holes
