2. PRODUCTS

2.1 Primer

Product: Bona White.

Chemistry: waterborne-1k.

VOC: 48.0 g/L.

Solids: 30.0%.

Coverage: 10.0-12.0 m2/L m2/L per coat.

2.2 Substrate compatibility

Bona White is not recommended for high tannin or darker timbers. It is not recommended that Blackbutt be coated with Bona White as tannin bleed is possible. Bona White is not recommended for use on darker or 'red' timbers as satisfactory coverage of the original colour will not be achieved, even by multiple applications. Bona Mega has a subtle rich tone; it is not recommended to overcoat Bona White primer with Bona Mega if a true white look is required - use Traffic HD Extra Matt, HD Raw, or Mega EVO Matt instead.

3. EXECUTION

3.1 Preparation

Sand to bare timber, final grit P120 or finer. Vacuum and tack-mop.

3.2 Application

Apply 1-2 x Bona White + 2-3 x Bona finish. Recoat per TDS (1-2 hours typical). On high-tannin species (Blackbutt, Tallowwood, Ironbark, Merbau) refer to the compatibility matrix - use Bona Intense unless another primer is specifically recommended for the species.

3.3 Compatibility with topcoat

Apply the specified Bona topcoat system within the manufacturer's recoat window or lightly sand P150 before the topcoat.
