Abstract:
Herein are disclosed wall repair compounds comprising at least one or more polymeric binder latex emulsions, one or more inorganic fillers, and comprising an amount of organic polymeric thickener that is less than about 0.1 percent by weight based on the total weight of the wall repair compound. In certain embodiments, the wall repair compound comprises an inorganic filler system selected such that such that synthetic inorganic fillers comprise essentially 100 percent of the inorganic filler used. In certain embodiments, the wall repair compound comprises one or more glycol ether smoothing agents.
