A primer 3 is essentially a protective layer that you apply before the first coat of paint. If you are painting over an already-painted surface, you may be able to avoid a primer 3 altogether by using a 2-in-1 paint and primer 1 3 product. However, if you are painting a surface that has never been painted before or changing the paint or finish type, it would be a good idea to prepare the surface using a traditional primer 3. Primers 3 should also be used when painting over hard, smooth surfaces like glass or tile. All three types of primers 3, oil-based, latex-based and shellac-based can be used under latex paint.

Interior and exterior paints need to stand up to entirely different menaces. Paint on the interior of your home will need to be cleaned or even scrubbed, while exterior paints need to be weather and sun-damage resistant. Both exterior and interior paints are a combination of pigment, solvent, resins, and additives. The solvent in paint keeps it liquid and spreadable until it dries on your wall or trim. Latex paint dries more quickly because its solvent is water, while the solvent in oil-based paints is mineral spirits, which takes more time to evaporate. Once the paint is applied, the solvent evaporates, and the resin allows the paint to adhere to the surface. Various additives in paint give it desirable characteristics, like moisture and scrub resistance. Louisville House Painting
Priming - $30–$40/hour for labor. Many of the materials above need to be primed, but not all do. If you’re changing paint colors from dark to light or light to dark, use a color similar to the top coat. That way you’re less likely to need extra coats over the standard two. Prime with a flat or eggshell paint. You can ask your paint store to add tint to the primer to match it with the top coat color. Hammer in exposed nails and spray them with a metal primer to prevent rust. House Painters Louisville
