Bona is the brand most Singapore wood-flooring contractors quote as the premium option for varnishing parquet, timber and engineered wood floors. It costs more than the standard water-based and oil-based products on the local market. This article explains where the cost goes, what you actually get, and which option fits which project.

We use both Bona and good-quality standard varnish systems. The right choice depends on usage, budget and how much downtime the homeowner can absorb during the coating cycle.

What "standard varnish" means in Singapore

Most local wood-flooring jobs are finished with one of two product categories:

  • Standard water-based varnish — single-component water-borne acrylic or polyurethane. Lower odour, dries in a few hours, good clarity. Commonly used brands include locally-stocked water-based PU varnishes from regional manufacturers.
  • Standard oil-based varnish — solvent-borne polyurethane. Slightly warmer (amber) tone, very hard once cured, but strong odour for several days and longer cure time.

Both have served Singapore wood floors for decades. They are perfectly capable products when applied properly over a well-sanded floor.

What Bona offers

Bona is a Swedish manufacturer that specialises in wood-floor finishing systems — sanding consumables, sealers, varnishes and floor cleaners. Two product families come up most often in Singapore residential work:

  • Bona Domo — single-component water-based varnish. Good clarity, mild odour, fast recoat times.
  • Bona Mega / Bona Traffic HD — higher-spec single-pack and two-pack water-based varnishes engineered for heavy traffic. Traffic HD in particular is the product specified for commercial floors and high-wear residential areas.

Most of the cost difference is in the two-pack products. A 2K (two-component) coating cures by chemical reaction rather than evaporation alone, which produces a tougher, more chemical-resistant film. That is why Bona Traffic HD is specified in showrooms, dance studios and high-end residences where the floor takes a beating.

Where Bona earns the extra cost

  • Wear life. A 2K Bona system on a residential floor often pushes the next screen-and-recoat from 3-4 years to 5-7 years. On commercial floors the difference is larger.
  • Chemical and water resistance. Bona Traffic HD shrugs off spilled wine, pet urine and cleaning chemistry better than a standard 1K water-based varnish. The film is not bullet-proof, but the recovery window is longer.
  • Consistency. Bona products are formulated and quality-controlled to one global spec. Standard local products can vary batch to batch.
  • System compatibility. Bona sealers, varnishes and cleaners are designed to work together. Using Bona Cleaner on a Bona-finished floor produces a known, manufacturer-supported result.

Where standard varnish makes sense

Bona is not the right answer for every project. Standard water-based or oil-based varnish is appropriate when:

  • The floor is in a low-traffic bedroom or guest room where a 1K finish will easily last 5+ years.
  • Budget is tight and the alternative is to defer the job — a well-applied standard varnish today beats a poorly-budgeted Bona job in 18 months.
  • The owner plans to refinish at every paint cycle (every 5-7 years) regardless, in which case the longer-life premium is not captured.
  • The floor is in a rental unit where the lifecycle calculation does not favour the premium spend.

Realistic cost picture

Pricing varies by floor size, condition and access, but a rough comparison for a typical Singapore residential job:

  • Standard water-based varnish — 3 coats is the baseline price.
  • Bona Domo (1K water-based) — 3 coats typically adds 15-30% on coating cost.
  • Bona Traffic HD (2K water-based) — 3 coats typically adds 50-80% on coating cost.

The sanding labour, board repairs and project overheads are similar regardless of the topcoat chosen, so the percentage on the total invoice is smaller than the percentage on coating-only. We provide a like-for-like quote with both options so the decision is made on numbers, not on brand pressure.

Application and downtime

  • 1K water-based (standard or Bona Domo): Tack-free in 1-2 hours, recoatable in 2-4 hours. Light foot traffic next morning, full cure in 7-14 days.
  • 2K water-based (Bona Traffic HD): Similar dry times, slightly longer cure. Full cure typically 7 days; furniture and rugs back from day 7.
  • Oil-based: Tack-free in 4-8 hours, recoatable next day. Furniture from day 5-7. Stronger odour for 3-5 days — significant if the homeowner cannot vacate.

For a typical 3-bedroom condo we plan three to four working days on site for sanding and coating, plus a cure window before furniture comes back. We confirm the exact day-by-day plan as part of the quotation.

How we recommend choosing

  • Living and dining rooms, family corridors, study with rolling chair: Bona Traffic HD if budget allows; Bona Domo or a good standard water-based otherwise.
  • Bedrooms: Standard water-based or Bona Domo is usually sufficient. Traffic HD is overkill for adult bedrooms; reasonable for a young-child bedroom with frequent toys and spills.
  • Wet-edge corridors near bathrooms or balconies: Always step up to a Bona 2K or a high-build standard PU. Recovery from splash incidents is the differentiator.
  • Holiday homes / second properties / rental: Standard varnish is usually right — the premium isn't captured during the lifecycle.

We're not tied to one product. We quote like-for-like, explain the actual difference and let the floor's usage decide. Whichever system goes down, it gets prepped, sanded and coated to the manufacturer's spec — that is what really decides whether the floor looks good in five years.
