Why Coats Matter
Each coat adds coverage over the paintable area. If one coat requires a certain amount of paint, two coats will usually require about twice as much before waste allowance.
Paint Needed = Paintable Area / Coverage per Coat x Number of Coats
What Affects the Number of Coats?
The right number of coats can depend on:
- The paint product and manufacturer guidance
- The condition, texture and porosity of the surface
- The difference between the old color and the new color
- Whether primer is used
- The desired finish and application method
Follow Product Guidance
Paint manufacturers usually provide instructions for coverage, surface preparation and recommended coats. Use those instructions when planning the project.
Estimate Paint With Coats Included
The Interior Tailor paint quantity calculator lets you enter the number of coats so your estimate reflects your project plan. After estimating paint quantity, you can preview your wall color before you start painting.
