Brunosol Concentrate 6X is a High Strength water soluble surface biocide based on Sodium 2-phenyl phenoxide used for the treatment of Dry Rot (Serpula Lacrymans) on masonry and brickwork.
Whilst Serpula Lacrymans does not derive nutrient from brickwork or masonry, viable spores or dormant vegetative growth within the structure can act as a source of re-infestation unless contained or eradicated. Brunosol Concentrate 6X fulfills this purpose by providing a biocidal barrier within the wall.
Approved under the Control of Pesticides Regulations 1986.
Dilutes to make 25 litres of working strength solution.
High Strength Formulation
Instantaneous action against Dry Rot
Deep penetration in Masonry
Sodium Phenylphenoxide 27.53% (w/w).
Rectify the defects contributing to the damp conditions which caused the outbreak (e.g. repair rain water drainage systems, roof leaks, etc; improve sub-floor ventilation, install DPC).
Expose the full extent of the outbreak, including a margin of clearance beyond the last visible signs of growth in all directions, remove all mycelium, built-in timber lintels, wall plates, bonding timbers and plugs from the affected walls and clearance areas and dispose of by burning.
N.B. If it is considered impractical to remove all timbers from infected walls etc, it may be possible to protect them in situ depending on the precise conditions prevailing etc.
1 part Brunosol Concentrate 6X should be diluted with 5 parts water.
A 4.2 litre bottle should be diluted to produce 25 litres of working strength solution, rinse container prior to disposal.
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS) AND SYNTHETIC RUBBER/PVC GLOVES PLUS EYE PROTECTION WHEN DILUTING OR SPRAYING OVERHEAD. SEE OUR SAFETY & PPE PRODUCTS
AVOID EXCESSIVE CONTAMINATION OF COVERALLS AND LAUNDER REGULARLY. COVER WATER STORAGE TANKS BEFORE APPLICATION. DO NOT BREATHE SPRAY MIST.
WHEN USING DO NOT EAT, DRINK OR SMOKE, DO NOT CONTAMINATED WATERCOURSES OR GROUND, PREVENT ANY SURFACE RUN-OFF FROM ENTERING DRAINS DISPOSE OF WASTE MATERIAL OR CONTAINER SAFELY.
Walls should be treated in depth with diluted Brunosol Concentrate 6X at the rate of 10 litres per m³ of brickwork or masonry.
4½” (115mm) brick walls can normally be treated by generous low pressure Spray Application (at 1 litre/2m²) to both sides of the wall.
Thicker walls will need to be drilled at approximately 230mm staggered intervals over the area to be treated (12- 16 mm drill bit).
Holes should be angled downwards between 30° and 45° to facilitate filling them with the treatment solution.
When the walls are drilled from both sides, the depth of the hole should reach the centre of the wall. If the walls are drilled from one side only, the depth of the holes should extend to within approximately 50mm of the reverse face of the wall.
Such treatments should be completed by surface application to both faces of the walls, although external walls need not be sprayed from the outside.
11” (280mm) cavity walls can be treated as two separate 4½” (115mm) walls providing sufficient access at suitable intervals to the cavity has been made to ensure proper application of the Brunosol Concentrate 6X to the faces of the brickwork exposed within the cavity. It should be ensured that the cavity is clear and where possible ventilated.
Local conditions, wall materials and type of construction would determine any variations which may be necessary to the suggested method of treatment to ensure the correct quantity of fluid (10 litres per m³) is evenly distributed within the mass of brickwork or masonry being treated.
Where the fungal growth has extended into the sub-floor area below a timber ground floor structure, the base of the structural walls, sleeper walls and oversite of the affected area must also be treated with Brunosol Concentrate 6X.
Where the growth has penetrated a concrete oversite or subsoil it should be excavated and the exposed surface treated with Brunosol Concentrate 6X solution.
Note: Areas below ground level (where sources of moisture cannot be isolated) may not be suitable for treatment using the above procedures.
1 litre of diluted product treats 2m² - 5m², 10 litres/m³.
N.B. UNPROTECTED PERSONS AND ANIMALS SHOULD BE KEPT AWAY FROM TREATED AREAS FOR 48 HOURS OR UNTIL SURFACES ARE DRY.
Ideally, any area affected by dry rot should be left exposed as long as possible after treatment to facilitate rapid drying out of the masonry / oversite. Nevertheless, re-instatement including re-plastering can proceed without delay after the application of Brunosol Concentrate 6X if required.
All replacement timbers should be treated with a suitable Wood Preservative and isolated from direct contact with masonry (e.g. use DPC material behind studwork for dry lining plasterboard or galvanised steel hangers to support joist ends). In cases where damp conditions are likely to persist, timbers should be treated by industrial pre-treatment as detail in BS 5589 : 1989.
If an inadequate sub-floor ventilation system was a contributory factor to the Dry Rot outbreak, steps must be taken to improve the system. This can normally be achieved by inserting additional or larger air bricks, strategically placed and free from obstruction (see BRE DAS 73, 1986).
Any obstructions within the sub-floor areas which would impede the cross flow movement of air must be dealt with. A satisfactory sub-floor ventilation system is one which will maintain the moisture content of the under side of the floor structure below 20%.
