Description

DETAILED DESCRIPTION OF THE INVENTION

(1) As mentioned above, a new composition for restoring the appearance of finished wood surfaces has been invented. The present compassion, in a most preferred embodiment, is a liquid including seven (7) different components. It is used on wood surfaces that are finished with solvent based topcoats (Oil Based Lacquers, Oil Based Polyurethanes, Oil Based Varnishes) to alleviate scratches, other demarcations and general breakdown of topcoat finish on these surfaces. The solution works on either stained or unstained finished wood with a solvent based topcoat and is also effective on water based and waterborne clear coat finishes.

(2) One or more embodiments of the present invention will now be described with the understanding that the following description is not intended to be limiting. Generally, the present composition comprises between 20 and 40%, by volume, of at least two oils; between 60 and 80%, by volume, of an organic, nonpolar solvent; and, at least two colorants. As used herein, the “by volume” refers to the relationship relative amounts of the oils to solvent and is based on the volume of the composition based on the amounts of the oils and solvent and not including any colorants or additional additives.

(3) Oils

(4) As noted above, the composition includes between 20 and 40%, by volume, of at least two oils, preferably between 25 and 35%, by volume, of the at least two oils and, most preferably approximately 30%, by volume, of the at least two oils. The oils are selected from the group consisting of: tung oil; boiled linseed oil; and olive oil.

(5) In a preferred embodiment, the tung oil, the boiled linseed oil, and the olive oil are all present in the composition, preferably, in nonequal amounts in the composition. According to one aspect, the composition includes between 15 and 20%, by volume, of the tung oil, between 5 and 10%, by volume, of the boiled linseed oil, and between 1 and 4%, by volume, of the olive oil. In a most preferred composition, the composition includes approximately 17%, by volume, of tung oil, approximately 8.7%, by volume, of boiled linseed oil, and approximately 2.3%, by volume, of olive oil. Based on qualitative testing, it is believed that this ratio of these oils is important for protecting the finish on the wood.

(6) Solvent

(7) As noted above, the composition also includes between 60 and 80%, by volume, of an organic, nonpolar solvent. The solvent, in addition to acting as a carrier for the oils, will dissolve the existing coatings on the wood that the composition is applied to, allowing the oils to soak into the wood and dry to form a protective barrier. Preferably, the composition has approximately 70%, by volume, of the organic, nonpolar solvent. It has been found through qualitative testing that this ratio is important for the overall applicable of the present composition. If the amount of solvent is too low, the composition will not the not penetrate the wood. Additionally, if the amount of solvent is too high, the composition will not work.

(8) With respect to the specific organic, nonpolar solvents that may be used, preferably, the organic, nonpolar solvent is a mineral spirit, and most preferably, the mineral spirits are high grade mineral spirits. It has been determined that a higher-grade mineral spirits dissolved the existing coatings on the wood better, making the composition more effective.

(9) Colorant

(10) The composition of the present invention includes at least two colorants to allow the composition to work on a variety of differently colored and stained woods varieties. Preferably, the colorants are raw umber and yellow oxide and are universal, and do not include a glycol, propylene, or formaldehyde carrier. The yellow oxide colorant provides the composition with tints that blend with natural woods and lighter stains. The raw umber provides the composition with tints that blend with darker stains. Therefore, too much of the raw umber results in the composition not blending well with lighter and natural stained materials.

(11) Preferably the composing includes 6/32 (per 2.3 L) of the raw umber and 12/32 of the yellow oxide (per 2.3 L). It is believed that the twice the amount of the yellow oxide as raw umber provides the most flexible results, and the amount of raw umber may be between 4/32 and 10/32. Excess raw umber will not provide as good of a tint, therefore, it is preferred, but necessarily required, that the raw umber not exceed the 10/32 of the yellow oxide (per 2.3 L) noted above.

(12) Additional Components

(13) Additionally, components may be included, for example, in one embodiment, 1 teaspoon (per 2.3 L) of turpentine was added to improve the compositions ability to dissolve the existing sealant on the wood. Other similar compounds may be added without overly impacting the effectiveness of the present composition.

(14) In Use

(15) A liberal amount of the composition is applied, using a rag, over the affected areas until the damaged wood is saturated. The re-colorization of the wood is almost immediately apparent. After 5-10 minutes, allowing the composition to fully dissolve the existing coating and penetrate the wood, the surface of the wood may be wiped with a clean, dry cotton rag. Once dried the surface of the wood will not appears as damaged and will not show a discernable different coloring from the treatment with the composition.

(16) The present composition is able to be applied to differently tinted wood surfaces and provides a tint that matches the surrounding tint already on the wood and does not suffer from the drawbacks of the currently employed solutions—it is fast and easy to apply, relatively environmentally friendly, and is not as costly.

(17) While at least one exemplary embodiment has been presented in the foregoing detailed description of the invention, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment of the invention, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims and their legal equivalents.
