About Chemicals For Dry Rot

Dry rot is a kind of fungus that only affects wooden matter that contains moisture more than 20%. They make the wood sponge like thus leaving behind a red powder. This fungus affects all the wood available in its surrounding. This fungus is considered very dangerous as it destroys everything that comes in its path, including brick and other materials. These dry rots can be controlled with the various kinds of chemicals available in the market.

Description of the chemicals:

The chemicals should be HSE approved, white spirit based solutions of the anti-fungal. Propiconazole and IPBC Polyphase are available in clear or colors such as red cedar, dark brown, golden brown, pale green and dark green. The white spirit carrier solvent enables the active to achieve deep penetration into most common sizes of structural timber, allowing the active ingredients to remain stable, effective and give long-term anti-fungal protection. The chemicals prevent the damage caused to timbers by "Serpula Lacrymanns", the dry rot fungus or "Coniophora Puteana", the wet rot version. Both of which can be found in timbers where there has been prolonged exposure to excessive moisture levels in a poorly ventilated environment. These active ingredients in the chemical also protect against the blue stain fungus which affects the surface appearance of external timbers. Clear and pale green preservers are suitable for over-painting and do not contain water-repellent properties, whereas Red cedar, dark and light Brown and dark green are more used on external applications and therefore do contain a water repellent additive.

Application of the chemicals:

The chemical can be applied with the help of a brush, spray or dip methods using up to 3 consecutive coats to achieve deeper penetration and a darker colour shade where necessary. It is better to use a broad bristled brush and apply the chemical evenly, soaking the timbers to refusal to achieve best results. Spray applications should be made with a coarse droplet spray nozzle held within 300mm surface of the treated timber at all times to limit wastage and reduce the risk of contaminating surrounding plants and structures.
