FAQ

How much paint do I need?

Litres = total wall area × number of coats ÷ coverage per litre. For 1200 sq ft, 2 coats at 120 sq ft/litre you need about 20 litres.

How many coats of paint are recommended?

Two coats are standard for even colour; dark shades or fresh plaster may need a primer plus two coats.

Does texture affect coverage?

Yes, rough or porous surfaces absorb more paint, reducing coverage per litre.
