Color-changing wood filling composition

1. A composition for use as a wood-filler, comprising:

(a) at least two styrene butadiene rubbers;

(b) at least one pH color indicator, wherein the pH color indicator is operative to provide a visual indication that the wood filling composition is dry; and

(c) microspheres, wherein the microspheres further include glass or ceramic, and wherein the microspheres are operative to provide durability and stainability to the wood-filling composition.

2. The composition of claim 1 , wherein the at least one pH color indicator is o-cresolphthalein.

3. The composition of claim 1 , further comprising at least one pigment.

4. The composition of claim 1 , further comprising water; at least one pH controller; at least one wetting agent; at least one dispersant; at least one freeze-thaw stabilizer; at least one bactericide; at least one mildewcide; at least one defoamer; at least one thickener; at least one calcium carbonate filler; at least one film former; and at least one lightweight extender.

5. The composition of claim 4 , wherein the at least one freeze-thaw stabilizer further includes propylene glycol; wherein the bactericide further includes an aqueous blend of chlorinated and non-chlorinated isothiazolinones and 2-bromo-2-nitro-1,3-propanediol; wherein mildewcide further includes liquid octylisothiazolinone; wherein the thickener further includes hydroxypropyl methylcellulose; wherein the calcium carbonate filler further includes dry ground marble or dry ground calcium carbonate; wherein the film former further includes 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; and wherein the lightweight extender further includes expanded polymer microspheres.

6. The composition of claim 1 , wherein upon drying, the color of the composition changes from purple to white.

7. The composition of claim 1 , wherein upon drying, the color of the composition changes from magenta to beige.

8. A composition for use as a wood-filler, comprising:

(a)at least two styrene butadiene rubbers;

(b) at least one pH color indicator, wherein the pH color indicator is operative to provide a visual indication that the wood filling composition is dry;

(c) microspheres, wherein the microspheres further include glass or ceramic, and wherein the microspheres are operative to provide durability and stainability to the wood-filling composition; and

(d) at least one pigment.

9. The composition of claim 8 , wherein the at least one pH color indicator is o-cresolphthalein.

10. The composition of claim 8 , further comprising water; at least one pH controller; at least one wetting agent; at least one dispersant; at least one freeze-thaw stabilizer; at least one bactericide; at least one mildewcide; at least one defoamer; at least one thickener; at least one calcium carbonate filler; at least one film former; and at least one lightweight extender.

11. The composition of claim 10 , wherein the at least one freeze-thaw stabilizer further includes propylene glycol; wherein the bactericide further includes an aqueous blend of chlorinated and non-chlorinated isothiazolinones and 2-bromo-2-nitro-1,3-propanediol; wherein mildewcide further includes liquid octylisothiazolinone; wherein the thickener further includes hydroxypropyl methylcellulose; wherein the calcium carbonate filler further includes dry ground marble or dry ground calcium carbonate; wherein the film former further includes 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; and wherein the lightweight extender further includes expanded polymer microspheres.

12. The composition of claim 8 , wherein upon drying, the color of the composition changes from purple to white.

13. The composition of claim 8 , wherein upon drying, the color of the composition changes from magenta to beige.
