Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality exterior primer and tint it to the color of your choice. Primer is the first coat applied to a surface. Primers have three purposes: Seal the surface, block stains, and be able to accept the protective paint coating. Each coat of paint from the first to last, must adhere to the surface on which it is painted. Each coat must provide “tooth” or surface to which each succeeding coat can bond. The first coat must have enough binder to get absorbed into, or stick to the material being painted with enough binder to accept the paint. Always follow the manufacturer’s instructions.

Primers are useful even for a simple color change. When covering an existing color with another color, painting without priming can produce a color that presents as a slightly different shade than the color selected. Primers should be tinted to the approximate finish color. When using a deep tone, a tinted primer won’t reduce the number of finish coats required, but will help the aesthetics through proper paint coverage. There are many brands and types of primers. Choose the one that is right for your job.

Priming

Primers are important. Knowing and understanding what each different primer does gets you the best painting results. Choosing the correct primer depends on the surface material, the surface condition, what you are trying to achieve, and the final look. Primer prepares and seals painted or unpainted surfaces. It helps paint adhere much better than if paint alone were used. In many instances, primer must be used before painting. Primer affects the longevity, durability and success of a paint job. Because the surface has been properly prepared, paint goes on smoother, spreads better, and protects the item being painted.
