- A critical step before adding primer to your new drywall is to remove all dust from the surface. Use a microfiber cloth, as well as a shop vacuum with a fine dust bag attached. According to Painting and Decorating Concourse, the vacuum should also have a fine filter cartridge attached. If the drywall dust is not removed before applying the primer, the primer will not stick to the wall. Poor adhesion causes texture to peel and bubble from the wall and create an unprofessional-looking texture and plaster finish.
- Roll on the primer the same way you paint a wall. Use even pressure, and do not force the primer onto the surface. Apply in vertical or horizontal strokes. If you notice the primer being absorbed quickly into the drywall, add a second coat. For the edges of the surface, use a paint brush or trimmer tool for the application. If you are painting a dark paint texture over your primer, use a gray primer instead. An additional option is to tint your primer at the paint store using about 75 percent of the color you are using to texture the wall. At most paint stores, a paint specialist will add the tint to the primer and mix the product. Tinting your primer decreases the number of coats you will need to cover the surface. Some texture paints are somewhat transparent, and the additional color underneath the surface allows the wall to appear professionally finished.
- Sometimes you only need to prime a small portion of your drywall, especially if the drywall has been slightly damaged. After repairing any holes or nicks in the surface, use a spray-on primer. It often comes in aerosol cans. Tape off the surface surrounding the areas and cover with plastic. This protects other areas of the wall from overspray. Hold the nozzle about 6 inches from the surface, and press down. The surface should dry for about two hours. Texture the wall with your desired plaster so it matches the other wall areas, and then paint.
- Some primers have a strong odor. Attempt to use a low-odor primer that is water-based to decrease paint fumes. When painting, open all windows, and turn on fans to increase air circulation. Don't forget to cover the flooring with drop clothes when priming and adding texture. Both applications can cause primer or texture paint to ruin carpet or other surfaces. Practice the texturing technique on posterboard if you have not worked with texture before.
