Brunosol Concentrate 6X – Professional Dry Rot Treatment for Masonry and Brickwork

Trusted in the UK and Northern Ireland for structural preservation, remedial damp control, and long-term dry rot protection

Effective Protection Against Dry Rot in Brick and Masonry Structures

Dry rot, caused by the aggressive fungus Serpula lacrymans, is one of the most destructive threats to the structural integrity of buildings across the UK and Northern Ireland. While this timber-destroying organism does not derive nutrients directly from brick or masonry, its ability to spread through damp walls, voids, and plasterwork makes containment especially challenging. Spores and dormant hyphae can lie in wait within porous substrates, reactivating under the right environmental conditions. For this reason, thorough sterilisation of all surrounding masonry and brickwork is critical during any dry rot eradication work and Brunosol Concentrate 6X is the professional solution of choice.

Specially formulated to penetrate deep into walls, oversites, and surrounding building materials, Brunosol delivers immediate and lasting results. Its concentrated biocidal action targets residual spores and fungal growth, preventing reinfestation even in challenging or concealed areas. This is not a superficial treatment, Brunosol provides deep molecular-level absorption, creating a protective barrier that actively resists fungal resurgence.

Professional-Grade Biocide with Proven Efficacy

Brunosol Concentrate 6X is a high-strength, water-soluble fungicidal concentrate containing sodium 2-phenyl phenoxide as its active ingredient. This product has been scientifically proven to deliver powerful action against dry rot fungal activity, disrupting biological growth cycles and sterilising infected masonry at depth. Unlike weaker surface sprays or amateur treatments, Brunosol is intended for professional use only. It is approved under the Control of Pesticides Regulations 1986, meaning it has been rigorously tested for efficacy, safety, and environmental responsibility.

When diluted at the correct ratio (one litre of Brunosol producing 25 litres of working solution) the product offers outstanding coverage and value. This dilution strength has been carefully calculated to balance effective biocidal action with safe handling for approved technicians. Once applied to exposed or treated masonry, Brunosol quickly begins penetrating the capillary structure of the substrate, targeting any biological contaminants within.

Designed for Use by Trained Remedial Specialists

Due to its strength and biocidal properties, Brunosol Concentrate 6X is supplied with a professional-use-only restriction. Customers purchasing the product may be required to verify their qualifications or training in accordance with pesticide regulations. This ensures the safety of both the user and occupants of the building while maintaining high industry standards for remedial treatments.

While DIY users or property owners may be involved in aspects of the renovation process, the application of Brunosol should always be performed by, or under the supervision of, trained specialists. This is especially important when dealing with dry rot outbreaks in structural timbers or heritage buildings, where improper application could result in ineffective sterilisation or damage to the structure.

Application Scenarios in Domestic and Commercial Buildings

The need for a deep-penetrating masonry biocide like Brunosol arises most commonly during dry rot eradication projects in damp-prone areas of a building. These areas often include cellar walls, oversite slabs, behind skirting boards, or the plaster lines surrounding previously infected timber elements.

During dry rot treatment, all visibly affected timber is removed, and adjacent masonry is treated thoroughly. Brunosol is applied either by spray or brush to the wall surface and can also be injected into boreholes for deeper penetration. In many cases, a series of horizontal and vertical boreholes are drilled into masonry walls, and Brunosol solution is injected to ensure full sterilisation of otherwise inaccessible cavities. This process creates a chemical zone of inhibition that prevents fungal strands from re-establishing within or through the structure.

Whether it’s an old granite foundation in Antrim, a sandstone wall in Glasgow, or a brick basement in Birmingham, Brunosol is suitable for all mineral-based substrates, offering long-term assurance that fungal activity has been neutralised at the root level.

Ideal for Heritage Restoration and Conservation Projects

Preserving historical and period buildings presents unique challenges. Dry rot can devastate old timber floors, joists, lintels, and decorative woodwork, and if left untreated, its mycelium can extend into adjacent plaster and masonry. In heritage sites or conservation areas where structural elements cannot be easily replaced, containment and sterilisation become the primary means of preservation.

Brunosol Concentrate 6X supports these efforts by offering a non-destructive, non-flammable, and deeply effective treatment that does not compromise the surrounding masonry or wall finishes. Its colourless finish and low odour formulation make it ideal for internal applications where minimal disruption to historic surfaces is essential.

By integrating Brunosol into a wider remedial strategy (which may include physical barriers, timber replacement, damp-proof membranes, or passive ventilation) contractors can treat dry rot outbreaks without compromising the aesthetic or historical value of a building.

Safety, Environmental Considerations, and Storage

As a regulated biocide, Brunosol Concentrate 6X must be handled with care. Technicians should wear appropriate PPE, including gloves and eye protection, and avoid contact with skin, eyes, and untreated areas. The product must not be applied in areas where it may contaminate drinking water supplies or waterways, and precautions must be taken to avoid runoff during use.

Once diluted, the solution should be used within a reasonable time period to maintain efficacy. Containers must be clearly labelled and stored out of reach of unauthorised persons. Unused concentrate should be kept in a cool, dry location away from direct sunlight, ensuring its long shelf life and chemical stability.

Brunosol’s non-flammable formulation also reduces risks during transportation and on-site storage.

Comparing Brunosol with Standard Dry Rot Products

While many damp proofing or timber treatment brands offer dry rot control solutions, few can match the deep absorption and long-term performance of Brunosol Concentrate 6X. Where competing products often rely on surface treatments or basic biocide blends, Brunosol’s high-performance active compound ensures sterilisation beyond the visible layers of plaster or render. Its deep molecular penetration allows it to reach and neutralise spores embedded within porous building materials, including sand-lime bricks, concrete blocks, and traditional clay-fired bricks.

This deeper action is what makes Brunosol the preferred choice among remedial specialists who cannot afford repeat infestation or secondary damage. The product has developed a reputation within the industry as a reliable first-line defence for dealing with established dry rot outbreaks in large-scale or legacy properties.
