What is a sponge paint brush used for?
Moreover, what do you use sponge brushes for?
Sponge Brushes Many times people prefer to use a sponge brush for crafts, to either apply paint, stain or glue. They are also useful for painting around the house, especially for small areas or when it's more convenient to use an inexpensive applicator that can simply be thrown away after painting.
Herein, can you paint walls with a foam brush?
Foam brushes are well suited to intricate work such as painting molding or window casings. These brushes are normally good only for one use, as they're hard to clean and easy to tear. Latex and water-based paints will dry out the bristles.
Foam brushes are fine for applying Minwax® Pre-Stain Wood Conditioner and any Minwax® stains, but they don't lay down a smooth final topcoat finish like quality bristle brushes do. Also, be sure to use a damp cloth as a final cleanup on the wood before staining or topcoating.
