Technical Spec

Coverage rate: 10-12m²/litre per coat

Drying time, until: - 2-3 hours at 20°C/60% R.H.

Preparation

Ensure the floor is acclimatized to its end-use environment. The surface which is to be coated must be sanded back to bare wood, dry and free from sanding dust, oil, wax and other contamination. It is recommended to finalize the sanding with a Bona Quattro or Multi Disc.

Allow the primer to reach room temperature.

Optimal application conditions are between 18-25°C and 30-60% relative air humidity.

High temperatures and low humidity shorten, and low temperatures and high humidity lengthen drying time. The minimum temperature for use is 13°C.

Application

1. Shake the container thoroughly before use and insert the supplied filter. Pour finish into a container (box + bag). It is recommended to pour through an external strainer so as to minimize the potential for lumps.

2. Apply Bona White using a roller (microfiber/fleece) at approx. 12 m²/lit (83 g/m²), avoiding the accumulation of product.

3. When dry (approx. 2-3 hours), abrade to reduce grain raise using the Bona Scrad system or a sanding screen grit 150 or finer.

4. Remove all dust

5. Apply an additional layer of Prime Natural sealing the surface with one of Bona’s protective lacquers
