How to Calculate Paint Requirements

Calculating paint requirements accurately saves money and prevents waste. Our paint calculator considers surface type, paint quality, coverage rates, and multiple coats.

Different surfaces absorb paint differently. Wood typically requires more paint per square meter than smooth interior walls. Our calculator adjusts for these variations.

Premium paints often have better coverage, meaning you may need less paint overall despite the higher price per liter. Consider total project cost, not just paint price.

Frequently Asked Questions

How accurate are coverage rates?

Coverage rates vary by surface texture, application method, and paint quality. Our calculator uses industry averages. Adjust the coverage rate if you know your specific paint's performance.

When should I use primer?

Primer is recommended for new surfaces, stained surfaces, or when changing colors dramatically. It improves adhesion and can reduce the number of topcoats needed.

Why is batch number important?

Paint batches can have slight color variations. Buying all paint from the same batch ensures consistent color throughout your project.

How long between coats?

Drying times vary by paint type and conditions. Water-based paints typically dry in 2-4 hours, oil-based in 8-24 hours. Always follow manufacturer recommendations.
