How it works
Compare the lightness of old and new colors, then allow a range for paint opacity and primer.
Simple example
Dark to very light without primer may take 3 or more coats.

Common question
Will primer guarantee fewer coats?
No. Paint quality, undertones and wall texture still affect coverage.
This is a planning estimate. Check product instructions, dimensions and site conditions before purchasing or building.
