COMMON QUESTIONS
Before you trust your walls to a can.
Why is real coverage lower than the sheet says?
Data sheets measure smooth, primed, professionally applied surfaces. On porous drywall or over dark colors, real-world consumption can be 20-30% higher — that is the gap between declared and practical.
What does 350 sq ft/gal per coat mean?
That one gallon paints that many square feet with a single layer. For two coats, divide the area by two — a gallon at 350 sq ft/gal covers about 175 sq ft at two coats.
Can I use these numbers for a budget?
Yes, as a starting point. Always confirm the label of the container you are buying and add margin for touch-ups and surface absorption.
Which containers do you include?
Quart (0.946 L), gallon (3.785 L) and 5-gallon pail (18.925 L) — the standard US sizes. Other containers are listed on each product sheet.
