BORON ULTRA 12 POWDER IN WATER - surface treatment for Woodworm and Timber Treatment - 01626 331351

 

Death Watch Beetle - special note

Death Watch Beetle requires more than surface treatment to eradicate an attack, because the insects have a long life cycle (up to 10 years) and rarely visit the surface of the timber. Treatment of 'normal' woodworm (Anobium punctatum) consists of surface treatment, by brush or spray, which breaks the egg laying cycle. Because their life cycle is short (up to 5 years) and their holes are smaller than Death Watch Beetle it is considered sufficient to treat the surfaces of the timber only - for Death Watch Beetle this will not be effective.

So, a Death Watch Beetle treatment must incorporate two additional features - internal, injection treatment and annual inspection.

Firstly, remove all loose material by brush and vacuum and ensure that the timber will absorb moisture. No surface treatment will penetrate varnish or paint. Next, drill injection holes in the 'active' damaged areas - test for these using a hammer first, listening for hollowness and then drill test holes. If in doubt call us - we can recommend a local professional company, if necessary.

The holes need to be blown or vacuumed out and then injected with Boron Ultra Paste. The holes can be capped with dowels, wood filler or plastic plugs.

Then finish with a surface treatment of either Boron Ultra Gel, or Boron Ultra 12 liquid at the 10% or higher concentration.

BORON ULTRA 12 - Surface Treatment

A unique powder concentrate, ready to dissolve in water, designed to treat timber by brush, roller or spray.. It avoids the hazard problems of many liquid preservatives by using only water as a carrier. It can also be used in most situations to replace other less ‘friendly’ contact type insecticides, including Permethrin. The powder can be dissolved in water in two main concentrations, depending on the intended use;

Concentration 1 - 0.5kg of powder dissolves in 12.5 litres of water, for normal common furniture beetle attack (woodworm, mild)

Concentration 2 - 1 kg of powder dissolves in 10 litres of water, for severe common furniture beetle attack and Dry Rot. Treats Dry Rot in timber and masonry, walls, floors and foundations. Also used as part of a Death Watch Beetle treatment.

or, you can purchase a ready mixed product;

Ready to Use - 5 litres or 25 litres of Boron Ultra 12 - already dissolved in water, for severe common furniture beetle attack and Dry Rot, both timber treatment and irrigation of masonry & sub-site soil

Powder is also available in 2.5kg packs - makes 62.5 litres for Woodworm Treatment or 25 litres for Dry Rot and Death Watch Beetle Treatments

Typical consumption rates - 2 timber floors, terraced house - 25 litres, or a roof, terraced house - 50 litres

How many litres will you need - click for more info.

Always follow the instructions on the product label, wear a dust mask when mixing and check with us before purchasing to ensure that you are buying the correct product.

Hole size - 1mm to 2mm in diameter.

Common furniture beetle, Anobium Punctatum, has a 5 year life cycle, but the adult only lives for a few weeks and cuts the hole you see in order to exit and find a mate. Eggs are laid onto the timber surface or in old holes. The baby grubs bore back in and the cycle repeats.

BORON GEL, PASTE, RODS - treatment to kill Woodworm and Dry Rot attack deep inside timber

1. ECOBOR ULTRA GEL 20 - Surface Applied Gel

A 20% active clear Gel ideal for end grain and bearing area treatment of beams and joists. Also useful for medium to heavy active infestations of insect attack and treatment of new timbers for use in vulnerable areas (e.g. skirting boards).

2. BORON ULTRA 78 - Deep Injected Treatment

A unique SUPER STRENGTH 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.

3. BORON RODS - Solid Rods for placing in holes to act as a reservoir

These solid rods of fused HIGH STRENGTH Boron 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 Sizes - 8mm x 24mm and 8mm x 65mm).

4. DRY ROT BARRIER PAINT - Coating

A special preservative biocidal emulsion paint designed to prevent the surface spread of Dry rot. Ideal for timber and masonry in the treatment of adjacent areas, to provide visual lasting evidence of treatment. It prevents surface spread of strands and mycelium.

Boron Kills Dry Rot
Example

Hampton Court - after the fire in the Cartoon Gallery - Boron in glycol was 'blown' into the ceiling voids below the gallery to eradicate mould and fungal growths, which were active because of the water pumped into the building above during the fire.

How to treat Dry Rot

1. Remove the source of moisture, ventilate, control humidity

2. Cut out the decay to sound timber/plaster, if structurally beyond repair

3. Apply Boron Ultra 12 powder in water by spray to timber and masonry, brush on Boron Ultra Gel to end grain and vulnerable surfaces, inject Boron Ultra Paste and insert Boron Ultra Rods to 8-10mm holes drilled to prescribed hole pattern, to surrounding areas at least 300mm in all directions from the limits of the attack and to all timbers at or above 18% moisture content.

Boron Ultra Paste injected into a lintol, awaiting plugs

Injecting Boron Paste
Example

Telegraph and Electricity Poles - these are susceptible to rot after the creosote treatment has diminished, especially in the ground zone, where splits and shakes allow moisture and air into the core. Boron Ultra Paste and Boron Ultra Rods are used in combination to prevent further decay and extend the working life of the poles.

How to treat Wet Rot

1. Remove the source of moisture, ventilate, control humidity

2. Cut out the decay to sound timber, where structurally weakened beyond repair

3. Apply Boron Ultra Gel to end grain and vulnerable surfaces, Boron Ultra Paste and Boron Ultra Rods to 8-10mm holes drilled to prescribed hole pattern in timbers at or above 18% moisture content.

Log House - treated with Borons
Example

The Log House, near Lymington - wet rot decay had destroyed a large number of logs on the weather side of this £1.5 million + home, facing Southampton Water. Boron Ultra Paste and Boron Rods were installed in the remaining sound logs to provide long term protection.

How to treat Woodworm

1. Remove the source of moisture, ventilate, control humidity

2. Cut out the decay to sound timber/plaster and/or de-frass

Wet Rot and Death Watch Beetle
Example

Bindon House Hotel - the roof tie beams were badly affected by Death Watch Beetle, Wet Rot and Dry Rot. These were replaced with TYPE E Timber-Resin Splice Units and the timbers were treated with Boron Ultra 12 by spray, Boron Ultra Gel to end grain and vulnerable surfaces and Boron Ultra Paste by injection.

How to treat posts and frames

Posts in the ground - use our special 'Save a Post' kit - drill holes in all four sides at ground level downwards at a 45 degree angle to overlap within the post beneath the ground. Blow out the holes. Inject Boron Ultra Paste to the base of the hole and insert a Boron Ultra Rod through the paste.

Frames and door legs - drill 8-10mm diameter holes above and below each joint to within 15mm of the opposing face. Blow out the holes. Inject Boron Ultra Paste to the base of the hole and insert a Boron Ultra Rod through the paste.

 

 

Railway Engineer detecting rot in sleepers

Testing Railway Sleepers for Rot
Example

Railway Sleepers - yes, these enormous, creosote treated timbers do rot and Railtrack have used 1000s of Boron Ultra Rods, but in a much larger size, to extend the life of these expensive components. Special carriage mounted Ultra Sound machines detect the rotting sleepers and these are then drilled, injected and capped as part of regular maintenance.
