What Is Undercoat Paint?

Undercoat paint can be defined as a layer of paint applied to a surface just before the application of the topcoat. It can also be considered as a primer coat since it creates a smooth and flawless base for the topcoat. This layer of paint enhances the effect, charm, and shade of the topcoat.

Undercoat paint also provides the walls with an additional layer of protection from moisture, rotting, and rusting of the walls, etc.


Significance Of Undercoat Paints

Even though some people believe that undercoat paint is unimportant, professional painters seem to disagree. Undercoat paint not only serves as a sealant or an adhesive for the painted wall but also prevents it from absorbing more paint than is necessary. The absence of undercoat paint could make the painting process twice as hard and time-consuming than it generally would be.


Undercoat Paint On Surfaces For The First Time

No matter what type of surface you are painting, if undercoat paint has never been applied to it in the past, then you must apply it now. Even if people say that it is not necessary, you must not take any chances and do it anyway. It will benefit you in the long-run.


Surfaces That Have Already Had Undercoat Paint Applied In The Past

Additionally, if you are working on a surface that has received undercoat paint in the past, applying another layer of undercoat paint to your wall will not hurt but you have the option to choose not to unless the paint you are planning on applying is water-based. Even though undercoat paints are usually color neutral, but a slightly tinted undercoat, based on the color of the topcoat might not be such a bad idea.


Especially when you have chosen either a darker or a brighter color, applying grayish undercoat paint could not only enhance the color and quality of the topcoat but also save you the trouble of applying multiple layers of the paint. You can ask for advice in this regard from any professional painter. You need to apply undercoat paint especially if the wall has fillings or stains.

Undercoat Paint vs Primer

Undercoat paint and primers are quite similar in their functions, i.e., both are used for evening out the surface before the topcoat is applied. It gets people confused and makes them unable to differentiate between the two.  


However, industry experts have found one key phrase to differentiate between the two. That key phrase states that “a primer may not always be undercoat paint but undercoat paint is always a primer.” Or you could say that primers cover a wider range of features while undercoat paints simply represent a small part of said wider range of features covered by primers.


Undercoat paint is crucial to the wellbeing of surfaces since it protects them from any potential damage from environmental and other factors as well as making them as smooth as possible for a better and more enhanced appearance of the topcoat. Choosing between a primer and undercoat paint solely depends on the purpose and nature of the surface you will be applying it to
