Which Factors Affect Number of Paint Coats?

‘How many paint coats do I need?’ is probably the most common question among homeowners undertaking new painting project. Most homeowners have this common misconception that application of a paint coat serves one single purpose of coloring the wall. So they believe that only single coat is enough as it is thick. Though a paint coat is meant to color the walls, it also serves other purposes as well. Yes, the paint is thick and strong and it protects your walls nicely. Sometimes one coat of paint is enough but more than one paint coat according to the requirement is ideal.

There are several factors that decide the number of coats of paint that your wall surface needs. The amount of paint depends upon the surface area and number of paint coats that will be applied. That is why understanding these factors are of primary importance.

Previous Paint Job

Previous painting job plays an important role in calculating the required number of coats. If the new color is the same as that of an underlying layer it will take less amount of paint to achieve the impartial composition.  And if the new color is not similar to the color of underlying layer, then the wall might need more than one paint coats. If the color underlying layer is lighter than the new color then one or two coats will be enough. If the underlying layer is darker than the new color then more than two paint coats become essential to achieve a fine look.


Primer is made to save paint! The easiest way to save application of many paint coats is by applying the primer. It is the best side-product in the painting project as it saves a lot of effort. It is very economical and easiest way to cover the existing color or just make your surface uniform before the application of paint.

Drywall Painting

If you are painting a new wall without priming it, at least first 2 paint coats will be utilized for smoothening the surface. And It will take several more coats to paint the wall. This process is time-consuming and expensive as the amount of paint will be a lot. In order to reduce the expenses and save time, priming the drywall beforehand painting is a great idea. It will reduce the number of paint coats significantly and your painting project will become a matter of one or two coats.

Quality of Paint

The quality of a paint makes a significant difference. The ingredients in low-quality paint don’t perform as well as that of a high-quality paint.
