Wash the walls thoroughly, in areas planned for the application. Use a mild and nonabrasive cleaner, such as dishwashing detergent or liquid soap,. Rinse and allow the area to dry completely.
Mix the drywall compound with a paddle bit, attached to a drill. A basic texture mixture consists of lightweight drywall compound and water. Measure six cups of drywall compound, inside a small bucket. Add water slowly, as additional drywall compound cannot be added to the mixture, without producing unsightly clumps. Use more water for a thinner texture or less water for a thicker texture.
Apply the texture material. Use a roller for thinner applications and textured paints. Apply thicker textures with a drywall texture gun, to achieve a splatter-type pattern. Use brushes to produce swirls and specific design patterns.
Step back and look at the wall from a distance. Correct any bare or uneven areas. Allow the textured finish to dry thoroughly. Do not touch the wall texture, until it has dried completely, as it is fragile. Carefully apply a finish coat of latex paint to seal and protect the wall from damage. Apply a second coat, if desired.
