How Much Varnish Do I Need for 20 m²?

For 2K varnish, calculate consumption per coat. Typically this is about 60 g/m² per coat with approximately 5% dilution with water. In practice, two coats are often applied, so always multiply the calculation by the number of coats and add a reasonable allowance for losses during rolling. For 20 m², generally two sets of varnish are required.
