2. PRODUCTS
2.1 Finish coat
Product: Bona Wave 2K.
Chemistry: waterborne-2k.
VOC (max, incl. hardener where applicable): 40 g/L.
Solids content (approx.): 31%.
Gloss level (60deg): Matt.
Packaging: supplied in the manufacturer's original unopened containers with batch identification. Do not site-mix products from different batches without manufacturer concurrence.
2.2 Primer / sealer
Prime with the manufacturer's system: 1 primer + 2 x Wave 2K.
2.3 Substrate compatibility
Substrate not nominated; verify species compatibility against the Bona species x primer matrix before tender.
3. EXECUTION
3.1 Preparation
Sand to bare timber with progressive grits, final pass P120 or finer. Vacuum and tack-mop immediately prior to coating. Ambient conditions to be within the manufacturer's stated range: 18-25 degrees C, 30-60% RH, substrate moisture content within the WoodSolutions / TFIA range for the species and locale.
3.2 Coating system
Apply 1 primer + 2 x Wave 2K in accordance with the TDS and attached Specifier Paragraphs. Coverage rate 8.0-10.0 m2/L m2/L per coat. Recoat interval 2-3 hours minimum at 20 degrees C / 60% RH. Light sand P150 or finer between coats where the inter-coat window is exceeded.
3.3 Cure and handover
Light foot traffic from approximately 6 hours after final coat. Full use from 12 hours. Cover with carpet / rug no earlier than 3 days after final coat. Do not wet-clean for 7 days.
3.4 Slip resistance
Where specified: classified to AS/NZS 4586 at not tested / refer to TDS (wet pendulum). Refer to attached test report PDF.
