Using primer before painting helps to seal the surface for improved color and sheen uniformity and also helps to achieve one coat coverage.
- New plaster should age 30 days before painting. Ace Alkyd Enamel Undercoater is the perfect choice for plaster. It seals the plaster so that when the paint is applied it provides a uniform finish. It also improves adhesion of the finish coat.
- Drywall should be primed with PVA Latex Wall Primer-Sealer. It smooths the paper nap of the drywall and helps the paint to provide a uniform finish.
- Bare wood should be sanded lightly before applying Ace Alkyd Enamel Undercoater. Wood trim that has been primed with an oil-based primer can be topcoated with either water-based (latex) or oil-based paint, depending on your preference.
- If the topcoat to be used is a custom mixed color, improved coverage can be achieved by tinting the primer with the colorant (up to a maximum of 2 oz. of colorant) used for tinting the finish coat.
- Surfaces stained by smoke, crayons, ink, or subject to tannin bleed through (common in some woods like redwood and pine) can be sealed using Ace Stain Block Primer. Be sure to wash the surface thoroughly, rinse well and allow to dry. The primer will seal the stains to keep them from bleeding through the finish coat of paint.
- Wallpaper should never be hung directly onto unsealed plaster or drywall. Prime first so that when you tire of the wallpaper it can be removed without peeling away the outer layer (paper coating) of drywall or gauging holes into the plaster.
