Wood floor sanding and varnishing Singapore
Wood floor sanding and varnishing — bringing aged parquet, timber and engineered floors back to a clean, even surface and finishing with water-based or oil-based coatings. Bona premium systems are available as a higher-cost option.
What this scope is
Sanding removes the top layer of wood — usually 1–3 mm depending on the floor’s condition — clearing old varnish, surface stains, light dents and ingrained dirt. The floor is then sealed and finished with multiple coats of varnish. Vacuum-equipped sanders capture most of the dust at source, giving a near dust-free environment in the working area.
Who this is for
- Owners refreshing an existing parquet or timber floor.
- Pre-handover refinishing for sale or tenancy.
- Worn high-traffic areas where deep scratches and dull varnish need to be reset.
- Properties where the wood floor is sound but the surface finish has failed.
Scope of works
- Furniture move-out coordination and floor protection of adjacent surfaces.
- Coarse, medium and fine sanding passes with vacuum-equipped equipment.
- Gap filling where required (slurry or filler-paste).
- Sealer / primer coat, then 2–3 coats of varnish (water-based or oil-based).
- Light inter-coat sanding (screen) between coats for smooth finish.
- Final clean and care-and-maintenance handover.
How we run a project
- Site visit — assess existing finish, board condition and any deep damage.
- Quotation — coats, finish sheen (matt / satin / gloss) and any board-replacement scope.
- Strip and sand to bare wood.
- Gap fill and any board replacements (see Parquet Repair & Restoration).
- Apply sealer, then coats of varnish; allow cure between coats.
- Defect walk-through and floor care instructions for the owner.
Water-based vs melamine (oil-based) varnish
Water-based coatings have lower odour, faster recoat times and a clearer, lighter film that leaves the wood close to its sanded colour — a common choice for occupied residential refurbishments. Melamine and other solvent-based oil-modified systems are the traditional finishes still widely used in Singapore parquet work: they amber the wood with a warmer, deeper tone and tend to feel slightly fuller on the board, but carry a stronger smell during application and a longer cure window. Site ventilation, drying time between coats and product compatibility with the existing finish all influence the outcome. Neither system is universally “best” — the right call depends on existing floor condition, the colour tone the owner wants, tolerance for odour, the available drying window and the budget.
Satin, matt and gloss sheens
Matt and satin finishes diffuse light and hide minor surface marks, scratches and footprints better than higher-gloss systems — satin is the most commonly specified sheen for living areas and bedrooms in Singapore. High-gloss looks more formal and reflective, but shows scuffs, dust and uneven sanding sooner. The same coating brand may publish slightly different gloss-unit values for matt, satin, semi-gloss and gloss tiers; the actual sheen on the floor also varies with the number of coats and inter-coat sanding.
Bona premium option
Bona is positioned as a premium wood-coating brand. Bona Domo (water-based, 1-component) and Bona Mega (water-based, oxygen-crosslinking PU) are common premium choices for residential and demanding floors. Bona finishes generally cost more than standard water-based and oil-based grades; we offer them as a higher-end option, not the default.
Visual reference
Things to confirm before fabrication
- Heavily damaged or warped boards may need replacement before sanding. Deep stains that seep through the wood layer cannot always be sanded out — these areas may need board replacement.
- Vacuum-equipped sanding is described as “near dust-free” because no sanding system in routine site use removes 100% of airborne particles. Adjacent rooms should still be sheeted off and soft furnishings covered.
- Curing times depend on coating brand and ambient humidity. Light foot traffic is typically possible within 24 hours; furniture and rugs should be held off until the finish has fully cured per the manufacturer data sheet.
