Before you head to the paint store, you’ll want to make some measurements of the area you intend to paint. In general, a gallon of paint covers about 400 square feet, according to Lowes. However, professional painters know how wall conditions can affect the amount of paint needed. Very porous surfaces absorb paint. In fact a heavy-bodied primer for that condition is often required.
Of course when you hire us to paint your house, we do all of the calculations and include the material costs in the bid. No guess work, no trips or return trips to the paint store.
