Preparation

by: William C. Darling


Painting is not merely about opening the paint can and firing away with the paintbrush, one has to prepare first the surface for painting. Here's how different surfaces are prepared for painting:

Unpainted Wood

Sand the surface to a smooth perfection. Using a tack cloth, wipe off the grit. Apply a latex enamel undercoat.

Previously Painted Wood

Clean the surface to remove any dirt. Get into cracks using an old toothbrush. Rinse with water. Dry. Remove any loose paint chips. Sand the surface enough to remove the gloss of the old paint. Using a tack cloth, wipe off the grit. Apply a latex enamel undercoat, but only to areas of bare wood.

Previously Varnished Wood

Clean the surface to remove any residual grease or dirt. Rinse with water. Dry. Sand the surface to remove any gloss. Wipe off the grit using a tack cloth. Apply a latex enamel undercoat.

Unpainted Plaster

Remove any dirt or grease on the surface. Sand if necessary. Using a tack cloth, wipe off the dust or grit. Apply a polyvinyl acrylic primer.

Previously Painted Plaster

Make sure the surface is free of dirt. Rinse with water. Allow to dry completely. Using Spackle paste, fill any cracks. Sand the surface to remove any gloss. Apply a polyvinyl acrylic primer if old paint was of dark or bold color.

Unfinished Wallboard

Using a dry piece of cloth, remove all dust. Apply a flat latex primer.

Previously Painted Wallboard

Clean the surface to remove any dirt. Rinse with water. Dry. Apply flat latex primer if old paint was of dark or bold color.

Fabric

Wash fabric. Don't use fabric softener. Dry. Iron. The fabric is ready. There's no need for any primer.

Metal

Using vinegar or lacquer thinner, clean the surface to remove any dirt. Dry. Sand the surface to remove any gloss or rust. Using a tack cloth, wipe off the grit. Apply rust-inhibiting latex metal primer.

Unglazed Pottery

Remove all dust with brush or vacuum with a soft brush attachment. Apply polyvinyl acrylic primer.

Glazed Pottery, Ceramic, and Glass

Remove all dirt from the surface. This is important as the paint will not cling to any surface which has dirt. Rinse with water. Dry. Apply stain-killing primer.

Now your canvas is ready. With your paint, paint mediums, finishes, tapes, paint rollers, paintbrushes, and applicators, you are ready to transform ordinary wood, clay, metal, or fabric into a masterpiece.
