Fungicide and hardener repairs and timber treatments

Fungal decay and wood rot should be treated immediately. If you believe your wood may be affected by either wood rot or fungal decay, then you should have a survey completed by a professional and have the wood treated or replaced as soon as you can. Wood rot and fungal decay is the result of moisture around the timber. When treating these conditions, it’s imperative to eliminate the moisture and allow the area to thoroughly dry out, prior to treatment. The recurrence of dry rot, wet rot, or fungal decay can be treated with a wood preservative such as a fungicide and hardener.

Typically the wood that has been affected by the wood rot or fungal decay must be removed along with the corresponding growths (such as fruiting bodies, strands and mycelium). As mentioned, the moisture source must be eliminated, and the timber must be dried out in order to be treated. Additionally, the nearby walls may be affected by damp so the plaster and masonry should be checked. If there is damp found in the walls, the fungal decay and wood rot can continue to spread evenly through the masonry. Moist wood creates the perfect environment for growing strands. These strands typically grow at the back of the plaster in search of more wood. To treat the surrounding walls, a masonry biocide can be applied. Subflooring can also be treated along with the remaining wood with a fungicide spray that is water-based.

Using a fungicide to treat timber rot and damage

Southern Damp Proofing Damp Proofing Services in London and the South East England uses a wood preservative with insecticide and fungicide technology. The particle size in this emulsion is in the nanometer range. By being in the nanometer range, the timber can be penetrated by the active ingredients so that they can be protected from dry rot, wet rot, and rotting wood fungi. This is because wood preservatives can only begin working if the fungi it is meant to protect against comes into contact with it. This treatment also protects from the infestation of wood, annoying insects.

Southern Damp Proofing Damp Proofing uses fungicides that are specific to the wood in the treatment of dry rot because it can treat and protect the wood better than traditional preservatives.

Using hardener to treat timber rot and damage

Some minor damage to the effective wood and joinery such as the frames of windows can be repaired by using a resin, or wood hardener. Before being treated with the hardener, the areas of decayed wood should be removed, and the adjacent surfaces must dry, then new wood can be spliced in, and filler can be used to seal any remaining gaps.

Hardener provides a strong base to bind and hardened the decaying wood. The filling cures wet rot and dry rot on the surface and goes down beyond the surface of the wood which will return the wood to optimal strength. This type of repair is ideal for frames, doors, and windows. It is important to note that this treatment can be used both outside and inside.
