FAQ
Where can I find the "coverage per liter" value?
Check the paint can or product packaging for the coverage estimate. Typical water-based paints cover roughly 8โ12 mยฒ per liter.
Why does the number of coats matter?
Depending on the base color and paint type, a single coat often leaves uneven coverage, so two coats are commonly recommended. The paint needed scales directly with the number of coats.
Should I buy more than the calculated amount?
Yes, it's a good idea to buy about 10% more than the calculated amount to account for uneven coverage and absorption loss.
