Abstract
A textured finish composition is disclosed wherein the composition comprises an acrylic latex/binder and an aggregate to form a textured composition. The aggregate is preferably a lightweight expanded mineral that has a density and weight that is less than sand. The expanded mineral is preferably silicone encapsulated in order to avoid the absorption of water. Most preferably, silicone encapsulated perlite is used as an aggregate for the textured finish composition. In one preferred embodiment, the textured finish composition comprises an acrylic binder and silicone encapsulated expanded perlite.
