Lignum Pro M50 is a concentrated biocide designed for the effective treatment of dry rot in masonry and brickwork. This HSE approved product carries the Approval No 10177 and dilutes with water to yield 25 litres of ready-to-use solution. Its advanced micro-emulsion technology creates a formulation with a particle size in the nanometer range, enabling deep penetration into masonry and brickwork to deliver the active ingredient effectively. This allows for rapid absorption and high active loading, making it especially well-suited for eradicating dry rot, particularly the Serpula Lacrymans species, in various masonry and brickwork applications.
The formulation's exceptional penetration ensures thorough protection, making it effective for sub-floor oversite sterilization in areas affected by dry rot outbreaks. Additionally, Lignum Pro M50 can be used in gauging water for the re-rendering of treated masonry, further contributing to its versatility and applicability.
Lignum Pro M50's water-based composition makes it virtually odourless, non-flammable, and quick-drying. Furthermore, it contains no VOCs, aligning with environmentally conscious practices and ensuring minimal impact on indoor air quality. These attributes make Lignum Pro M50 a reliable and user-friendly solution for combating dry rot in masonry and brickwork.

IPBC (3-Iodo-2-Propynyl Butyl Carbamate) is a key ingredient in Lignum Pro M50 Biocide, helping to fight dry rot in walls made of bricks and stone. When this chemical is used, it prevents the fungus from building its cell walls correctly, which stops it from growing and spreading.
The Lignum Pro M50 Biocide formula is designed to soak deep into the affected material, reaching the root-like parts of the fungus that can cause damage. This deep reach means the treatment works effectively and provides lasting protection, as it can keep fighting any leftover fungus spores. Since IPBC works especially well against the dry rot fungus, it makes the biocide a focused treatment for this common problem in buildings. The product, with IPBC, is a powerful and targeted way to protect structures from the damage caused by dry rot..
The active ingredients in the formulation are sourced and supplied by manufacturers who have supported their compounds through the Biocidal Products Directive [98/8 EC] or more recently the Biocidal Products Regulations [528/2012] and in compliance with Article 95 of the Biocidal Products regulations.
Take the usual labour hygiene into account.
PPE should be worn during application. See our Safety & PPE Products.
Consult label and material safety data sheet for more information.
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.
Apply by spray, brush or injection. This product requires dilution with water.
Read statutory conditions relating to use prior to application.
For surface sterilisation, saturate surface of wall using a course spray. Where fungal growth is extensive i.e. penetrated the wall structure, then irrigate the wall through holes drilled two thirds of the wall depth at staggered 230mm centres and at a downward angle into the mortar beds so as to ensure full penetration.
Surface Spray: (1 - 2 coats) 1 litre of diluted product per 5m² of surface.
Irrigation: 10 litres of diluted product per 1m³
Coverage may vary with the properties of the substrate.
Unprotected persons and animals should be kept away from treated surfaces until dry.
Product is stable in original packaging for 2 years when stored under ambient conditions. After 2 years product should be re-tested every 6 months to ensure active ingredient levels are within specification.
