Definitions

  • This application relates to a method for preserving wood and other substrates, and to kits for use in such methods.
  • a wood preservative to wood
  • the choice of application method depends primarily on the type of preservative (eg solid, liquid or gaseous state, waterbased or solvent based) and the subsequent hazard to which the treated wood will be exposed.
  • a preservative applied by a penetrating process pressure impregnation
  • a partially penetrating process is preferred, so that as much of the susceptible timber as possible is treated with preservative and hence protected against attack by microorganisms.
  • treatment using a partially penetrating process is preferred.
  • the resulting preservative envelope, surrounding an untreated core provides a protective barrier against wood destroying fungi.
  • Water diffusible biocides are widely used to treat external joinery components. This technology is based on inserting solid implants of the diffusible biocide into the timber and is usually carried out as part of a remedial treatment process as opposed to pre-treatment during manufacture. This technology relies on the fact that when the timber becomes wet and the risk of decay increases, the biocide will be mobilised and prevent any subsequent attack by decay organisms. As long as the timber remains dry, (below about 20% moisture content) there is no significant risk of decay and the biocide will remain in its immobilised state.
  • the primary disadvantage of such systems is that being water diffusible, the biocides will be susceptible to leaching from the wood, and will therefore be gradually depleted until the amount of biocide in the wood is insufficient - 3 -
  • a method of preserving a substrate as herein defined which comprises applying to the surface of the substrate a biocide and a polymeric compound and implanting into the substrate a preservative composition comprising a water diffusible biocide.
  • biocide and polymeric compound may be applied to the surface in the form of separate compositions, one comprising the biocide, and the other comprising the polymeric compound, but preferably they are applied in the form of a single, surface-applied preservative composition comprising both the biocide and the polymeric compound.
  • the invention will be discussed below with reference to methods wherein the surface treatment is applied in the form of a single surface-applied preservative composition comprising the biocide and the polymeric compound, but it will be understood that preferred features of this surface-applied composition discussed below are also applicable, where relevant to methods wherein the surface treatment is applied in the form of two separate compositions.
  • the preservative compositions used in the method of the invention may be used to treat substrates such as wood or other solid cellulosic materials (such as medium density fibre board and other composite products).
  • substrates such as wood or other solid cellulosic materials (such as medium density fibre board and other composite products).
  • solid cellulosic materials such as medium density fibre board and other composite products.
  • the surface-applied preservative composition affords protection until the diffusible biocide is solubilised and has diffused into the susceptible areas of the wood.
  • the moisture content of the timber eventually increases, the water diffusible biocide is solubilised and provides protection against fungal attack.
  • the combination of treatments used in the method of the invention results in far better overall protection of the wood than would be expected from the results obtained when wood is treated with either form of preservative composition alone.
  • the method of the invention is particularly suitable for the treatment of external joinery (such as window and door frames) and overcomes all of the disadvantages of the known treatments of such products.
  • the method is applied to treat joinery components before they are used in construction, rather than as a remedial treatment after decay has already occurred.
  • This enables the application of the surface-applied composition to all surfaces of the component so that a substantially complete protective envelope around the component is formed.
  • the method may also be used for the protection of timber to be exposed externally in, or out of ground contact or used in the construction of buildings.
  • the various treatments may be applied in any order, for example, the surface- applied preservative composition may be applied before the composition comprising the water-diffusible biocide is implanted into the wood, or these two treatment steps may be reversed.
  • the implanted preservative composition is preferably in the form of a solid implant or paste.
  • the water diffusible biocide must be of sufficient solubility in water to enable diffusion of the biocide through the wood when the wood becomes moist and vulnerable to decay.
