Surface Prep: Priming

Cracked or Peeling Paint

Priming is always recommended to enhance coverage, adhesion and durability of the topcoat. Surfaces that should be primed include:

  • All unpainted surfaces (such as bare wood, plaster or new drywall)
  • Wallpaper
  • Patched or repaired areas
  • Paneling
  • Stained surfaces
  • Surfaces painted with oil-based paint
  • Surfaces that will have an extreme color change (light to dark or dark to light)

After priming interior walls or other surfaces, all painting should be done within twelve hours for best adhesion.

Choosing Paint Primer

Latex (water-based) primer should be used on the following surfaces:

  • New drywall
  • Previously painted, patched and repaired or stained surfaces
  • Galvanized metal

Alkyd (oil-based) primer should be used on the following surfaces:

  • Paneling
  • Bare wood
  • Wrought iron and other metals that will rust
  • Wallpaper
  • Water stains or severe stains
  • Cracked or Peeling Paint
  • Patching holes and cracks
  • Removing Wallpaper
  • Sanding
