Triton Systems | Masonry Biocide
Trisol 23 is a High Strength, Third Generation, Bicontinuous Microemulsion Concentrate formulated for the sterilization of masonry infected with Dry Rot Fungus (Serpula Lacrymans).
Other uses include the control of Mosses, Lichens and Algae on external surfaces.
Trisol 23 does NOT contain:
Trisol 23 contains 3-iodo-2-Propynyl-N-Butyl Carbamate as the active ingredient, which is commonly referred to as IPBC.
This ingredient is used for the following reasons:
Trisol 23 carries the HSE Approval No 6274.
Supplied in 1 Litre containers, concentrated solution.
High Strength Solution (IPBC at 5.0% w/w)
Trisol 23 is supplied as a concentrate for dilution with water in the ratio of 1 to 24.
One litre of Trisol 23 makes 25 litres of Ready to Use Solution.
Once diluted, the dilution contains IPBC at 0.2% w/w.
When mixed with water, a stable Microemulsion is formed which is low in odour.
No petroleum solvents used.
IPBC (3-Iodo-2-Propynyl Butyl Carbamate) 5.0% w/w: A biocide that provides the maximum spectrum of biological activity against the dry rot fungus (Serpula Lacrymans).
Determine the full extent of the dry rot outbreak by opening up the affected area, identify and remove infected timbers (cut back in-situ timbers 500mm beyond last signs of fungal growth or strands).
Remove plaster/render in all directions 500mm past the last signs of fungal growth or strands.
Identify and rectify the cause of dampness associated with the dry rot outbreak, i.e leaking gutters, poor ventilation, rising damp etc.
Clean all wall areas and oversites to remove surface growth and strands, use a stiff brush on walls if necessary.
Thoroughly prepare all surfaces, which are to receive treatment.
Remove surface fungal growth and strands using a stiff brush.
Rake out mortar joints to a minimum depth of 10mm.
Strip off plaster to one metre beyond any visible sign of infection or dampness.
Remove all built-in and decayed timber or to limit disturbance. Consider using the Boron Based Wood Preservatives Wykabor 20 and Wykabor 40.
Sterilise all exposed wall areas with two to three coats of Trisol 23 solution using a coarse low-pressure spray. Initially concentrate on flooding the mortar joints but ensure that at least one full coat is applied to the entire surface. Brush application is suitable for small areas.
Oversites should be sprayed until saturated with fluid, debris containing spores or growth should be removed where possible from these areas.
Where severe Dry Rot outbreaks have occurred and adjacent timbers embedded in, or abutting to, masonry surfaces are not yet infected or where isolation is required because timbers are not readily removed, then traditional irrigation and injection to form a ‘cordon sanitaire’ or toxic box may be carried out.
The wall should be drilled to two thirds depth at 23cm (9”) staggered centres angled downwards to help retain fluid.
The holes should be filled repeatedly to obtain an application rate of 2.5 litres per square metre (9” brickwork).
Coarse Spray: 1 litre per 1-3m² of surface.
Irrigation / Injection: 2.5 litres per m² of 230mm (9") Brickwork.
Unprotected persons and animals should be kept away from treated surfaces until dry.
