Product Description:


Microtech Biocide is a unique formulation containing ‘Polyphase’ (a carbonate fungicide) for the control of dry rot (Serpula Lacrymans) in walls and the removal and prevention of moulds, algae, mosses and lichens from interior/exterior surfaces.

The special properties of this unique micro emulsion system give fast action and excellent absorption rates in walls when sprayed or injected.


Advantages:


  • Dilutes to make 25 litres of Ready-to-use Product
  • Unique micro emulsion system.
  • Instantaneous action against dry rot.
  • Deep penetration in masonry.
  • Non-flammable.


Application (For Dry Rot Treatment):


On Walls: Walls should be treated in depth with diluted Microtech Biocide at the rate of 10 litres per m³ of brickwork masonry. 4.5” (115mm) brick walls can normally be treated by generous low pressure spray application (at 1 litre per 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 (12-16mm drill bit). Holes should be angles downward 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 4.5” (115mm) walls providing sufficient access at suitable intervals to the cavity has been made to ensure proper application of the Biocide 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.

On Floors: Where the fungal growth has extended into the subfloor 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 Microtech Biocide. Where the growth has penetrated a concrete oversite or subsoil it should be excavated and the exposed surface treated with Microtech Biocide solution.


Application (For External Treatments (Algae, Moss, Lichens)):


Following dilution, application can be either with a low pressure pneumatic sprayer (course spray) or by a watering can with a fine rose attachment. For small items such as headstones, etc.,

Microtech Biocide solution may be applied by brush provided the solution is flooded generously into inscriptions and other cavities. Always direct the spray away from the body; do not spray directly overhead.

For maximum effectiveness Microtech Biocide should be applied when surfaces are reasonably dry and when rain is not imminent. Treatment should take place in win free conditions to minimise spray drift.

Once existing organic growth has been killed by initial application (1-7 days) this should be removed by brushing or power hosing followed by a second application of Microtech Biocide. In the case of roof treatments temporary wire netting guards should be provided over down pipes and the gutters cleared of dead moss, etc. once all the debris has been removed.

Retreatment will be necessary at intervals to prevent growth becoming re-established. The life of treatments may be considerably shortened on:

A) Surfaces subject to excessive mechanical wear
B) Very dense substrates which do not absorb much fluid
C) Surfaces where dirt etc. is allowed to accumulate
D) Persistently damp surfaces.

Note: We do not recommend the use of this product on asbestos cement surface due to the risk of fibre release and dispersal during cleaning.
