Drywall compound is typically used in most textured wall and ceiling finishes. Typically used for embedding drywall tape, the plaster is now commonly used as a light wall texture. It comes in both dry and wet versions available at your local hardware store. Additional plasters are available with sand or other compounds added for a more texturized, stucco appearance.
Nearly all hand applied textures are executed with a trowel. A drywall trowel has a smooth flat edge and smooths on the plaster to the wall. Use the edge of the trowel to create ridges in the wet plaster. When using the trowel, the joint compound will build up and begin to dry on the surface. Keep a five-gallon bucket of water handy and wash off your trowel often.
Once your textured walls have dried, they require a light sanding. Sanding the walls removes any loose texture, sharp edges and gives the finish an even thickness. Use a medium sanding block, electric hand sander or drywall sanding pole. When sanding, protect your eyes and wear safety goggles. A dust mask is recommended to avoid breathing in small dust particles. After sanding, wipe down the textured walls with a damp sponge.
Add color to your textured walls with latex paint. A roller for textured, rough walls evenly spreads the paint and saves time. The first coat of paint is generally immediately absorbed into the drywall compound. Often, two or more coats are needed. When painting the texture a dark color, such as red, prepare the wall with a gray primer first. After your last coat of paint, inspect walls. Use a chip brush, and dab paint into textured areas the roller is unable to cover.
