Explaining the difference between a finish and an undercoat is somewhat simple. Primer is formulated to glue it self to a surface. Paints are formulated with an ingredient that bonds to the primer. Always buy the best undercoat that you can afford. Never let primers sit to long before applying your top coat of exterior or interior design paints. Also prep and repair any PROBLEMS your indoor or outdoor surface may have before undercoating.


Quality primers are easy to sand, and create good binding or grip for the top coat. They have mildew resistance and, end with the completed project having a smother, thicker, surface. Undercoats also give the final finish better sheen and color retention properties, especially on a rougher areas. Sealers keep paint from being absorbed into a surface and will block stains such as ink on walls or tannins in wood. Primers and sealers can be purchased as an ALKYD or a LATEX. Oil or latex undercoats are usually finished with products derived from the same base. This is not a hard fast rule some surfaces require an alkyd primer, top coated with a latex finish and visa versa. Alkyd undercoats work best for chalked areas or wood like cedar that has a tendency to bleed. Due to there ability to breath latexes performs best when water or humidity is a concern. If you’d like to save a little money have the dealer tint the primer to the color of your exterior or interior design paints. By doing so you may be able to get away with an undercoat and one finish. If you end up having to apply another top coat it will look that much better in the end.

Older Wood:
Wood that's seen a few seasons should be scraped if pealing and then sanded. Once the area is properly prepped apply either an oil or latex undercoat.
