Applying base coats

 

Base coats are used to hide formerly applied colours, smooth surfaces and increase adhesion of paint. For best results, do not tint base coats.

Base coats are used to hide formerly applied colours, smooth surfaces and increase adhesion of paint. For best results, do not tint base coats.

Base coats include primers, sealers, stain-killers and undercoats. Primers are applied directly to bare surfaces like metal and wood. Sealers are used with porous surfaces like new gypsum (drywall) to keep it from soaking up multiple coats of paint. Stain-killers hide stains and remove the smell of smoke. Undercoats are applied over previously painted surfaces.

Checklist

Applying a base coat:

  1. To ensure excellent adhesion, make sure paint and base coat come from the same manufacturer.
  2. Place masking tape on any surfaces you do not want painted, like switches, windows, door handles, and so forth.
  3. Apply base coat generously, leaving no “holidays” or excesses (see “Handling brushes and rollers” section).
  4. Let dry.
  5. Lightly sand between coats if necessary using grades 180 to 220 of sandpaper and vacuum up dust.
  6. Let surfaces dry completely before painting.
  7. Clean tools.
