Bona Mega is a waterborne floor finish that uses oxygen in the air to achieve crosslinking. This gives it the performance and durability of a two part finish without addition of a hardener. Very easy to apply with brush or roller and quick drying. Two to three coats required. For superior adhesion we recommend applying one coat of Bona Prime prior to use. Coverage 10-12sq Metre per litre. One five litre container is sufficient for two coats in an average sized room (20 sq metres)
