When You Need Primer
Prime new drywall (it absorbs up to 40% more paint than primed surfaces), any surface with water stains or smoke damage, and when switching from a dark to a light color. One primer coat typically replaces one topcoat in your total count.
On previously painted walls in good condition with no dramatic color change, you can skip primer and go straight to two coats of finish paint.
FAQ
How much does one gallon cover?
350-400 sq ft on smooth walls. Textured surfaces or color changes reduce this 15-25%.
Do I need two coats?
Almost always. Two coats give even coverage and match the color swatch.
Should I subtract doors and windows?
Yes. A door is about 21 sq ft and a window about 15 sq ft. Subtracting them avoids over-buying.
