All bats are protected under The Wildlife and Countryside Act 1981. Before treating any structure used by bats, consult Natural England, Scottish National Heritage, The Countryside Council for Wales or The Department of the Environment for Northern Ireland.
Before deciding on appropriate preservative treatment, carefully evaluate the structural integrity of timbers and repair and / or replace those considered unsound (isolated from masonry where possible). Locate and rectify any sources of dampness.
ProBor 50 can be used to treat sound (new or existing) timbers. For timbers already suffering from fungal decay / insect attack, treatments can be applied effectively as long as measures are also taken to remove sources of moisture and / or improve ventilation in the adjoining areas.
Timbers left in direct contact with masonry below ground level, or in other situations where there is a known continuing source of moisture, can be treated in-situ but should be re-inspected periodically to access their condition.
Cover water storage tanks and remove or cover fish tanks and bowls and any food stuffs etc. before application. Do not use on food preparation or storage surfaces.
ProBor 50 is a deeply penetrating product which causes staining to both the treated timber and any porous materials it is contact with (e.g. plaster, masonry).
Further, when timbers are dry, the boron salts may appear as surface crystals in places.
THESE FACTORS MAKE THIS PRODUCT SUITABLE ONLY FOR THE TREATMENT OF STRUCTURAL TIMBERS WHICH WILL NOT BE EXPOSED AS A DECORATIVE FEATURE.
If sensitive linings or overlay materials are to be used in direct contact with treated timbers they should be isolated by the use of an impervious barrier.
If treatments are being carried out as part of a dry rot eradication program carefully establish the full extent of the infestation and use ProBor 10 to sterilise affected masonry as necessary.
Holes of 10-12mm diameter should be drilled at intervals of 100mm along the grain and to within 15mm of the full depth of the timber (and otherwise as per the table below).
Inject the ProBor 50 to within c. 10mm of the face of the timber and seal with timber dowling or Plastic Plugs.
Holes of 10-12mm diameter should be drilled at intervals of 150mm along the grain and to within 30-75mm of the full depth of the timber (see the table below).
Inject the ProBor 50 Paste to within 30mm of the near face and seal with timber dowling or Plastic Plugs.
Approx. 5 kg/m³ (Refer to Drilling Patterns in tables above)
Provide a physical barrier to prevent unprotected persons and / or animals coming into contact with treated surfaces until dry (inaccessible timbers are considered to be outside this requirement).
Dispose of empty cartridges carefully; transfer old nozzles to new cartridges wherever possible.
