Lightweight wall repair compounds

摘要

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.

主权项

1. A wall repair compound, comprising,
from about 20 percent to about 80 percent by weight aqueous latex binder emulsion that comprises an acrylic binder, and from about 20 percent to about 70 percent by weight of an inorganic filler system comprising substantially spherical synthetic particles comprising glass bubbles;
wherein the wall repair compound is configured so that when a cavity in a wall is filled with the wall repair compound and the wall repair compound is allowed to dry and at least the dried wall repair compound is painted with the proviso that a primer is not applied to the dried wall repair compound before the dried wall repair compound is painted, the painted dried wall repair compound does not exhibit flashing.
