Things You'll Need:
- Paint Brush
- Primer
-
Step 1
For fresh dry wall: Using a latex primer or a PVA specified for dry wall is the best option, since primers that have an oil base may damage that surface.
-
Step 2
To change wall color: Use an acrylic-latex primer that is compatible with the color of the top coat. If you’re painting a light color over a darker one, for example, make sure to prime the walls well with a light-colored primer, or your sunny yellow could end up looking more like a deep mustard. If the top-coat tint is a deep color, think about a primer that may enhance the look.
-
Step 3
For a smooth or glossy finish: When working with dry wall or plaster, use an undercoat that is latex enamel, and once it’s dry, lightly sand it down. For trim, using an oil-based undercoat results in a glossier finish, as it seals the surface area.
-
Step 4
To cover up stains: For water stains, try an oil-based stain blocker, but as far as other permanent blots, consider an acrylic-latex stain blocking sealer.
-
Step 5
To do away with odors: Using a pigmented shellac-based primer is most strongly suggested, however you may also want to try an oil or latex stain blocker.
-
Step 6
Natural Wood: An oil-based primer or any general purpose acrylic latex will get the job done, however, when working on redwood or cedar, apply a coat of stain blocker.
-
Step 7
Metal: Apply a double coat of rust or corrosion-inhibiting metal primer.
-
Step 8
Various surfaces, such as laminate, glass and plastic: Before beginning to apply any primer, you should sand the surface lightly. Then the surface is ready for a shellac-based or specially formulated latex bonding primer.
