Exterior Paints - Primers & Undercoats

Good Exterior Primers & Undercoats are critical to achieving a professional, even paint job. Primers are designed to properly adhere to and seal surfaces, preventing paint from peeling. Unlike paint, a primer is specifically designed for application on bare substrates, such as to render, wood, metal, and MDF.

A Primer is usually a white colour; however, you can often ask the supplier for the tint to be added so that its colour is a near match to the topcoat you're be applying. This will result in a better overall colour application. Multiple coats of a primer may be necessary when applying a drastic colour change, such as a dark to light, or light to dark, solid covering stripes, and so on. Shiny (i.e., gloss paint) paint that is in good condition will still need to be primed, after a light sanding.
