Accurately estimate your paint requirements
How much paint you’ll need depends on several factors:
- Surface area: How large is the area you’re painting?
- Number of coats: Will you need one or two coats of paint?
- Surface material: Will the surface absorb a lot of paint?
- Paint can size: How many gallons does each can hold?
