Types of Primer (Paint) that You Need to Know

Not every painting project needs primers. But, using primer before painting will make the result looks stunning and make the paint sticks better and longer. If you haven’t been familiar with primer, the first thing you should do is to get to know it. Below is some information about primer that you need to know before applying it with your airless spray paint brush and etc.

Drywall Primer
It is a good idea if you want to achieve a consistent appearance with your final coat. Besides, you can save your tight budget with a quality drywall primer. It is typically much less expensive per gallon than using multiple coats of a quality interior latex paint.

Wood Primer
It can be said that bare wood is one of the most difficult substrates for a paint topcoat to stick to. In fact, it takes a long time for an oil based primer on bare wood to dry. Yet, it will stick longer than any other type of primer to wood.

Even though it sticks better, but some people do not want to wait too long. Fortunately, paint manufacturers have developed new, faster-drying technology in both oil and latex-based products that dry quickly yet still aid in the proper adhesion of your paint topcoat.

Masonry Primer
There are several factors why you need to apply a masonry primer before paint. First, if you apply paint directly to the surface, some masonry surfaces can have a high pH level cause adhesion problems. However, using a quality masonry primer will enable you to safely paint over a wider range of pH levels.

Next, Efflorescence is another problem. Efflorescence is a crystalline deposit that can form on any masonry surface. It looks unsightly white in your wall. Fortunately, many masonry primers are efflorescent-resistant and do a great job of keeping it from becoming a problem.

Stain-Blocking Primer
You can find much kind of stain-blocking primers which are aimed for specific uses. In general, stain-blocking primer is usually used to keeping water and smoke stains/damage from bleeding through the finish coat; painting over top of crayon, marker, or grease. Besides, it can also be used to make a dramatic color change, especially, if you are planning to paint a lighter color over a darker color.

Bonding Primer
Each surface has their characteristics. Some surface are especially “slick” and make a good challenge for even the best primers to stick. For instance, ceramic tile, glazed block, some plastics and vinyls, and surfaces with a high gloss finish. But, don’t worry as the correct bonding primer will produce a great adhesion of your finish coat to the surface.
