What is Primer?

Primer must be applied before painting either in outside building’s components or inside partitions and walls. It is really important to prepare the surface by sanding it before applying any coat of primer paint. The primer chemical components will assure that the surface being painted will last longer and the final product should be more eye-appealing. Furthermore, applying primer before the paint coat will provide extended paint coverage and will provide a smoother finish appearance. Primer should be applied over drywall, wood, metals and painted surfaces.

Primer Importance

Applying primer over new surfaces might reduce the amount of paint being absorbed by the surface. When it is applied over drywall, the primer will hide seams and joints effectively. However, there are several kinds of primer, and choosing the right one, will make the difference with the final look and the finish surface will look even better. The main function of priming is to ensure that any successive layers of paint adhere to the surface properly.

Sometimes primer could be mixed with a small amount of the paint into the primer. This mix will be very helpful when the final color of the surface is lighter than the original color of the surface. The list below contains some of the basic primer types.

Primer: Oil Based

An oil-based primer is one of the bestfor areas that get a lot of touching and use, such as doors, windows and cabinets. Oil-based primers require mineral spirits for thinning and cleanup. They are great providing barriers to keep wood from bleeding through. These types of primers are good to use on unfinished wood, cedar. Weathered wood and over existing paint that is cracking.

Primer: Latex Primer

Latex primers are great for blocking stains and even better when the surface has areas that were filled with paste. They provide a great flexible finish with excellent cracking resistance. Latex primer are great over bare wood, but be sure to try it first to see if they raise the grain. Use on interior and exterior surfaces including woodwork, drywall, plaster, masonry, brick and painted metal.

Primer: All Purpose

An all-purpose primer is ideal on interior and exterior applications. All-purpose primers are versatile and usually provide strong adhesive properties, making it a superior favorite primer. All-purpose primers works without the solvent odors and high VOCs common with most stain-blocking primers.

Primer: Enamel

An enamel primer is usually applied over metal and wooden surfaces. This type of primer will serve as a protective and decorative coating. It’s great when used under flat or enamel paint and can be gently sanded prior to painting. This type of primer comes in satin, gloss and semi-gloss finishes

Primer: Paint and Primer in One

A paint and primer product will cover and seal in one coat. These primer products will work for painted surfaces, providing excellent coverage in one coat. Primer cost could be estimated as half the cost of paint, so you must evaluate whether to use this product or not. Sometimes you might want to have one coat of this all in one product and then apply the final paint coat. However, as with any all in one product, be very careful that the product you are using can serve as both and that the quality offered is the one you are expecting.
