Questions
About the gallon calculator
How accurate is it?
It uses the common rule of about 350 square feet per gallon and subtracts doors and windows. Real jobs vary, so we measure on site.
Why add a cushion?
Touch-ups and uneven surfaces use more paint, so a little extra helps.
Do I need primer too?
Often yes, especially for repairs and big color changes. We tell you when it is needed.
