Primer - paint Home improvement.



Let’s try to make it simple, its basically the coat that preps any surface before paint to insure extended durability, adhesion and protection, these are basically the 3 main reason why primer should and must be used before paint.

Any unfinished surface, such as drywall, metal, wood, and concrete should be primed before applying the first coat of paint. Sometimes it can be really tempting to skip this important step however the results could be disappointing.


100% of the time the respond its yes, any unfinished surface or new surface should and must be primed, At first glance applying primer may seem like an unnecessary expense, but it actually saves money as well as time. A good coat of primer improves paint’s hide, or ability to cover, reducing the number of coats that are necessary to achieve a smooth finish.

Primer will not affect the color of the finish paint. You can also have the primer tinted to the chosen finish color, and this will generally eliminate one coat of paint. Two layers of application should be enough.


If you have a situation in which you’d be dealing with the following scenario :

-Grease surface

-Hole patches and wall repairs

-Glossy wall and wished to switching to flat paint

-Dirty surface

-Unfinished drywall

-Unfinished wood

-Unfinished metal

It is really important to prep the surface by sanding it before applying any coat of primer .The most important function of the primer is that it will assure that the surface being painted will last longer and the final product can be more appealing. Furthermore, applying primer before the paint coat will provide extended durability and will provide a smoother finish appearance.


Primers are available in oil, shellac, or latex-based formulas. Each type has differing properties and uses a different solvent for thinning and cleanup. Choosing which type to use is largely a matter of matching the primer’s characteristics to the project at hand.

-Latex Primer.

Latex primers are the best choice for unfinished drywall, since they act to even out the texture and sheen between the wallboard and joint compound. They also allow water vapor to pass through, which can make them less likely to peel.

-Oil Primer.

An oil primer acts as a stain blocker. If there are stubborn stains on the surface that you cannot remove, a single layer of latex primer should cover the stain. A maximum of one more layer should be used if one layer doesn't cover it.

-Shellac Primer.

shellac primer has a specific purpose, masking severely damaged walls. These may be walls damaged by dampness or smoke. For smoke damage from a fire or heater blow back, shellac or alcohol primer is the first choice. A single layer is enough to hide minor problems. However, further layers should be added until smoke or water damage has disappeared.

-Clear Coat Primer.

Clear coat primer is perfect for using on newer walls. This primer is much thinner than other alternatives. The purpose of clear coat primer is to create a surface over a wall that will help the paint to stick. If you're planning to paint a brand new wall, a single layer is all that will be needed.
