Wykamol Microtech Biocide - Masonry Dry Rot Treatment

Health & Safety Recommendations

Before handling Wykamol Microtech Masonry Biocide, ensure you are wearing appropriate personal protective equipment, including gloves, goggles, and protective clothing. A face mask should be used in poorly ventilated areas or when spraying to avoid inhaling mist or vapours.

Avoid contact with skin and eyes, and do not ingest the product. If skin contact occurs, wash immediately with soap and water; in case of eye contact, rinse thoroughly and seek medical advice. Always keep the product out of reach of children and pets. Store the biocide in a sealed container in a cool, frost-free location between 5°C and 25°C.

Once diluted, use the solution within seven days. Dispose of unused product, diluted solutions, and packaging responsibly in accordance with local regulations.

Substrate Suitability

Wykamol Microtech Masonry Biocide is suitable for application on masonry surfaces affected by dry rot, dampness, or fungal infestations. The product can be used on brick, stone, and other porous substrates as part of a dry rot eradication and treatment programme. It is also effective on oversites that require sterilisation. This product is designed for professional use and is most effective when applied to thoroughly prepared surfaces.

Surface Preparation

Effective treatment begins with thorough surface preparation. Identify and eliminate the source of moisture that triggered the dry rot outbreak, ensuring that the area remains as dry as possible. Promote rapid drying of timber and masonry by improving ventilation.

Using a stiff brush, remove all visible fungal growth and strands from the surface. Mortar joints should be raked out to a minimum depth of 10mm, and plaster should be stripped back to at least one metre beyond any visible signs of damp or fungal growth.

Decayed or built-in timbers should be removed. Alternatively, wood preservatives such as Wykabor 20.1 or Wykabor 10.1 can be used to limit disturbance. Remove all debris, spores, and fungal growth from the area, bagging the waste carefully to prevent re-infestation.

Application Method

Dilute Wykamol Microtech Masonry Biocide at the recommended ratio of 160g of concentrate to produce up to 25 litres of solution.

The biocide can be applied using a coarse low-pressure spray, ensuring thorough saturation of the affected areas. Focus initially on flooding the mortar joints but apply at least one full coat across the entire surface. Small areas can be treated using a brush to ensure full coverage. Oversites should be sprayed until saturated with the solution.

For severe outbreaks, traditional irrigation or injection techniques may be necessary to isolate the infestation. Drill the wall to two-thirds depth at staggered 23cm intervals, angled downwards to help retain the solution. Fill the holes repeatedly to achieve an application rate of 2.5 litres per square metre for standard 230mm (9-inch) brickwork.

Coverage

The coverage of Wykamol Microtech Masonry Biocide varies depending on the application method. For coarse spray applications, one litre of diluted solution covers 1-3m², depending on surface porosity.

For injection or irrigation methods, the application rate is 2.5 litres per square metre for standard 230mm brickwork. Ensure sufficient solution is applied to achieve complete sterilisation.

Drying

After application, allow the treated surface to dry naturally. Drying times will vary based on environmental conditions, ventilation, and substrate porosity. Ensure the area remains well-ventilated to facilitate drying and prevent additional moisture ingress during the curing process.

Finishing

Once the treated area is dry and sterile, you may proceed with restoration or finishing processes. Apply suitable wall finishes or coatings only after confirming the area is free from active fungal growth and completely dry.

If timber restoration is required, ensure new timbers are protected with appropriate preservatives, such as Wykabor products, to prevent re-infestation.

Cleaning

Clean all tools and equipment immediately after use with clean water to prevent product residues from hardening. Dispose of cleaning water and any remaining diluted solution responsibly. Contaminated materials and waste should be bagged securely and disposed of in compliance with local environmental guidelines.

Q) What is Wykamol Microtech Masonry Biocide used for?

A) Wykamol Microtech Masonry Biocide is specifically designed to sterilise masonry surfaces affected by dry rot fungus (Serpula lacrymans). It effectively eliminates fungal spores and prevents their regrowth, ensuring the structural integrity of the treated masonry. Additionally, it provides reliable control over mosses, lichens, and algae on external surfaces, making it a comprehensive solution for both remedial treatment and preventative maintenance of masonry structures.

Q) How does Wykamol Microtech Masonry Biocide work?

A) The active ingredient in Wykamol Microtech Masonry Biocide, 3-iodo-2-propynyl-N-butyl carbamate (IPBC), disrupts the metabolic processes of fungi and other biological contaminants, preventing their growth and colonisation on masonry surfaces. The biocide penetrates deep into porous masonry, effectively targeting fungal spores and providing long-term protection. The microemulsion technology ensures uniform distribution and consistent efficacy.

Q) Is Wykamol Microtech Masonry Biocide suitable for all masonry types?

A) Yes, Wykamol Microtech Masonry Biocide is formulated for use on a variety of masonry substrates, including brick, stone, and concrete. It can be used in both modern and historic buildings without causing damage to the materials, provided it is applied according to the manufacturer’s guidelines. However, it should not be used on timber surfaces; for timber treatment, Wykamol recommends Microtech Dual Purpose or Lignum Pro Gel.

Q) What are the benefits of using Wykamol Microtech Masonry Biocide?

A) The benefits of using Wykamol Microtech Masonry Biocide include its highly effective control of dry rot fungus, mosses, lichens, and algae.

Additionally, its concentrated formula provides cost-effective coverage, with one pack diluting to make 25 litres of ready-to-use solution.

Q) How should Wykamol Microtech Masonry Biocide be applied?

A) The biocide should be diluted at the recommended ratio of 160g to 25 litres of water and applied using a coarse low-pressure spray to achieve thorough surface saturation. For smaller areas, it can be applied using a brush. In cases of severe dry rot infestations, injection or irrigation methods may be required to ensure the solution penetrates deeply into the masonry structure.

Q) What is the recommended coverage of Wykamol Microtech Masonry Biocide?

A) Coverage depends on the application method and surface porosity. When applied by spraying, the diluted solution typically covers 1-3 square metres per litre. For injection or irrigation applications in standard 230mm brickwork, a rate of 2.5 litres per square metre is recommended to ensure full penetration and sterilisation of the affected area.

Q) Can Wykamol Microtech Masonry Biocide be used indoors and outdoors?

A) Yes, the product is suitable for both indoor and outdoor applications.
