Your questions answered

How do I calculate how much paint I need?

Use our PaintBuddy calculator by entering your room dimensions, paint type, and number of coats. The tool will instantly calculate the paint quantity and cost for your project.

What’s the difference between matte, satin, and gloss paint?

Matte paint has a flat finish and hides imperfections, satin has a slight sheen and is easy to clean, and gloss paint is highly reflective and durable. Choose based on your project needs.

How much paint do I need for a 12x12 room?

For a 12x12 room with 8-foot ceilings, you’ll need approximately 1.5–2 gallons of paint for two coats. Use our calculator for precise estimates.

Can I use the same paint for walls and ceilings?

While you can use the same paint, ceilings often require a specific ceiling paint that is flatter and less reflective. Check the paint label for recommendations.

How do I estimate paint cost?

Enter your room dimensions and paint type into our calculator. It will estimate the total cost based on the paint quantity and price per gallon.

What tools do I need for a painting project?

You’ll need paint brushes, rollers, trays, drop cloths, and painter’s tape. Check out our recommended products for high-quality tools.

How do I prepare a room for painting?

Clean the walls, fill any holes, sand rough areas, and apply painter’s tape to edges. Use a primer if needed for better paint adhesion.

How many coats of paint do I need?

Most projects require two coats for even coverage. Dark colors or drastic changes may need a third coat. Use our calculator to adjust for multiple coats.
