Abstract

A wood preserving composition comprising a drying oil, a non-drying oil and a wax, preferably lanolin, to provide a semi-drying, semi-solidifying weatherproof coating for wood.

Description

SEMI DRYING SEMI SOLIDIFYING TIMBER PROTECTION AND PRESERVING WAX OIL

With LANOLIN (SHEEP WOOL GREASE)

This invention is intended for the long term preservation and protection, primarily for outdoor timber by repelling moisture absorption as well as preserving the natural elements within the timber and simultaneously providing an effective protection against the ultra violet rays from sunlight

Most conventional products currently available react with air when applied and oxidize. This results in the coating drying and solidifying. Most products penetrate the near surface layers of the timber and solidify when dry. With the expansion and contraction of the timber, the solid coatings crack, resulting in moisture penetrating into the timber, as well as causing the timber to dry out.

This invention is a blend of drying oils, such as Linseed, Tung, Walnut and non drying oils such as mineral oils — the result being a "semi dry" finish. When applied the mixture will penetrate the near surface layers of the timber and leave the surface dry to the touch as well as non-slippery. The uniqueness of this invention is the addition of lanolin (sheep wool grease) to the blend. The final mixture is unique in that the coatings when applied to timber will semi dry as well as semi solidify. The lanolin will not dry out and crack nor will the blend of drying and non drying oils. This is a unique combination. The Semi Drying Semi solidifying Oil blend may substitute lanolin with other suitable waxes, for example paraffin wax, bee's wax or any other similar wax. The lanolin further shields the timber from moisture ingression as well as providing a natural protection against ultraviolet rays. As in nature the lanolin protects the sheep from the cold and wet as well as protecting the wool fibres from sun damage. This invention when applied to timber will semi dry and semi solidify therefore, it will not crack and will stay in a pliable state. The unique oil blend may include components to improve protection against ultra violet rays, such as a Hindered Amine Light Stabilizer and Ultra Violet Light Absorbers. Other coatings that remain in a pliable state such as synthetic materials may be used in combination with lanolin or other suitable waxes.

A further unique feature of this invention is, when timber that has been previously treated, will not require any surface preparation when a subsequent coating is required. The fresh oil when reapplied with a mop, brush or scourer will clean the surface and because of the semi dry semi solid state of the old coat, the fresh oil will dissolve the old oil and wax and mix in with the new oil. However, if the surface has been neglected and a build up of dirt has accumulated over a long period of time, the surface will need to be cleaned before applying a subsequent fresh coating. This will allow new oil to penetrate the timber and deposit a fresh protective weatherproof coating to the surface. With conventional timber finishes, when re application is needed, varying degrees of surface preparations are required including mechanical stripping (sanding) to chemical stripping. These processes can be time consuming, costly and some are a danger to health and can be harmful to the timber.

Further uses for this invention can be for the protection and preservation of materials such as cork, Hessian, Bamboo, Cane, Sisal, leather, canvas, and other natural and man made fibre products. It is also an effective concrete sealer as well as providing protection for steel reinforcing embedded in the concrete. It is also suited for sealing other types of paving such as sand stone, terracotta, and other similar materials.

Claims

The claims defining the invention are as follows:

1. The protective Semi Drying Semi Solidifying Coating when applied to timber will remain in a semi dry semi solid state, enabling it to match any movement of the timber exactly.

2. The unique blend of oils and lanolin wax (sheep wool grease) effectively prevents moisture absorption as well as preventing the timber drying out.

3. The protective Semi Drying Semi Solidifying Coating will help to preserve the timber by retaining the natural tannin within the timber and thereby the timber will retain its own natural colour.

4. Because of the unique combination of oils and wax regular on going care and maintenance is very easy as no surface preparation is required.

5. With regular periodic subsequence applications when required the timber will be protected and preserved for a very long period of time.

6. The protective Semi drying Semi Solidifying Coating remains in a pliable state and effectively' seals the timber from inside as well as the outside.

7. The protective coating will absorb deep into the timber and remain in a pliable semi solid state.

8. The Semi Drying Semi Solidifying Coating is particularly effective in sealing extremely dense timbers. It will absorb in to the timber and remain in a pliable state.

9. It will not form a solid dry membrane on the surface, therefore, it will never crack and peel.

10. The addition of lanolin to the Semi drying Semi Solidifying Coating provides a natural ultra violet light protection. This is improved with the inclusion of a hindered amine light stabilizer and ultra violet absorbers.
