Common questions
How many gallons to paint a house exterior?
A typical 1,500 square foot single-story house takes about 8 to 12 gallons for two coats.
Do I need primer on the outside?
On bare wood, patched areas, and big color changes, yes. Many paint-and-primer products cover sound, previously painted siding.
Is spraying faster than rolling?
Much faster, but it uses more paint and needs careful masking.
