- 4. The composition of claim 1 further comprising resin microspheres having a density of from about 0.56 lb/ft3 (0.009 g/cc) to about 8.1 lb/ft3 (0.13 g/cc).
- 5. The composition of claim 1 wherein said binder comprises a latex binder.
- 6. The composition of claim 1 wherein said wax is present in a concentration of about 0.1 wt % to about 8.0 wt % on a dry basis.
- 7. The composition of claim 1 wherein said synthetic polymeric wax comprises at least one water soluble polymer formed by the addition reaction of water with at least one of propylene oxide, ethylene oxide or alkoxy-substituted ethylene oxide.
- 8. The composition of claim 7 wherein said filler comprises at least one of calcium carbonate, calcium sulfate dihydrate or calcium sulfate hemihydrate.
- 9. The composition of claim 7 wherein said synthetic wax comprises polyethylene glycol.
- 10. The composition of claim 9 wherein said polyethylene glycol has a melting point of from about 110° F. (43° C.) to about 150° F. (66° C.).
- 11. The composition of claim 9 wherein said polyethylene glycol is present in a concentration of about 4.0 wt % to about 8.0 wt % on a dry basis.
- 12. The composition of claim 7 wherein said synthetic wax comprises methoxy polyethylene glycol.
- 13. The composition of claim 12 wherein said methoxy polyethylene glycol has a melting point of from about 80° F. (27° C.) to about 129° F. (55° C.).
- 14. The composition of claim 12 wherein said methoxy polyethylene glycol is present in a concentration of about 2.0 wt % to about 4.0 wt % on a dry basis.
- 15. The composition of claim 12 wherein said synthetic polymeric wax comprises a methoxy polyethylene glycol blend having an average melting point from about 95° F. (35° C.) to about 115° F. (46° C.).
- 16. The composition of claim 12 wherein said synthetic polymeric wax comprises a blend of polyethylene glycol and methoxy polyethylene glycol.
- 17. The composition of claim 15 wherein said blend comprises at least two methoxy polyethylene glycol compounds.
- 18. The composition of claim 1 wherein said polymeric wax is present in a concentration of about 0.5 wt % to about 6.0 wt % on a dry basis.
- 19. A method of finishing a joint between adjacent gypsum board panels comprising applying a composition to said joint, said composition comprising water, a filler, a binder, a thickener and at least one synthetic polymeric wax that is at least slightly soluble in water and forms a solid at room temperature.
- 20. The method of claim 19 further comprising taping said joint.
- 21. The method of claim 19 further comprising allowing said composition to dry and sanding said joint.
- 22. The method of claim 19 wherein said synthetic polymeric wax comprises a methoxy polyethylene glycol having a melting point of from about 80° F. (27° C.) to about 129° F. (55° C.).
