FAQs
Does this cover both sides of the door?
No — the result is for one face. Double the total if you are painting both sides.
How accurate is the paint estimate?
It assumes 10 m² per litre per coat, a typical figure. Porous or dark surfaces may need more.
Can I use it for glass or panels?
Yes — the area figure works for any material you need to size for a door face.
