When deciding whether or not to prime, the surface condition, product being applied and colour must all be taken into consideration. Primer is usually recommended for new or previously unpainted surfaces. Unpainted surfaces, such as new drywall or wood, will always benefit from a coat of primer to seal and even out the surface porosity, as well as assisting with the adhesion of the finish paint. Surfaces with patch repairs or coated with a dark or strong colour will yield more satisfactory results if a primer is applied first. Some deep or rich colours require a colour foundation or tinted primer to achieve the colour desired. Glossy surfaces require a super-adherent bonding primer before painting. We carry a number of top quality self-priming paints that in some instances can eliminate the need of a primer.
