In certain aspects, the latex resin may have an average latex particle size of less than about 0.18 microns, a minimum film formation temperature of less than about 15 degrees Celsius, and/or a glass transition temperature (Tg) of less than about 25 degrees Celsius. To further enhance the self-priming performance of the spackling compound, the formulation may further comprise a colorant such as titanium dioxide. ## Claims ### Claim 1 A spackling compound, comprising: (a) between about 35% by weight and about 65% by weight acrylic latex resin; (b) between about 20% by weight and about 50% by weight filler material; and (c) between about 1% by weight and about 20% by weight water; wherein the acrylic latex resin has a minimum film formation temperature of less than about 15 degrees Celsius. ### Claim 2 (depends on 1) A spackling compound as defined in claim 1, wherein the acrylic latex resin has a glass transition temperature (Tg) of less than about 25 degrees Celsius. ### Claim 3 (depends on 1) A spackling compound as defined in claim 1, further comprising at least one colorant. ### Claim 4 (depends on 3) A spackling compound as defined in claim 3, wherein the dried spackling compound passes the 6 mil hide test set forth in the specification. ### Claim 5 (depends on 4) A spackling compound as defined in claim 4, wherein the spackling compound comprises between about 2% by weight and about 20% by weight colorant. ### Claim 6 (depends on 5) A spackling compound as defined in claim 5, wherein the colorant comprises titanium dioxide. ### Claim 7 (depends on 6) A spackling compound as defined in claim 6, wherein the colorant further comprises carbon black. ### Claim 8 (depends on 7) A spackling compound as defined in claim 7, wherein the carbon black comprises less than about 0.02 percent by weight of the spackling compound. ### Claim 9 (depends on 1) A spackling compound as defined in claim 1, wherein the spackling compound further comprises a coalescing aid. ### Claim 10 (depends on 1) A spackling compound as defined in claim 1, wherein the coalescing aid comprises trimethylpentanediol monoisobutyrate. ### Claim 11 (depends on 1) A spackling compound as defined in claim 1, wherein the coalescing aid comprises less than about 1% by weight propylene glycol. ### Claim 12 (depends on 1) A spackling compound as defined in claim 1, wherein the spackling compound further comprises a dispersing agent. ### Claim 13 (depends on 12) A spackling compound as defined in claim 12, wherein the dispersing agent comprises less than about 1 percent by weight of a sodium salt of polymeric carboxylic acid. ### Claim 14 (depends on 1) A spackling compound as defined in claim 1, wherein the spackling compound further comprises a lubricant. ### Claim 15 (depends on 14) A spackling compound as defined in claim 14, wherein the lubricant comprises less than about 1% by weight hydroxy ethyl cellulose. ### Claim 16 (depends on 1) A spackling compound as defined in claim 1, wherein the filler comprises a bimodal distribution of particles. ### Claim 17 (depends on 1) A spackling compound as defined in claim 1, wherein the bimodal distribution of particles comprises at least one of glass bubbles and ceramic microspheres. ### Claim 18 (depends on 1) A spackling compound as defined in claim 1, wherein the filler is substantially free of mined organic filler materials. ### Claim 19 (depends on 1) A spackling compound as defined in claim 1, wherein the dried spackling compound has an average 85 degree gloss retention index of at least about 0.3 when testing according to the method set forth in the specification.
