Parquet floors look better and last longer when they are cleaned the right way, kept inside a sensible humidity range, and recoated before the surface wears through. This guide is the routine we recommend to Singapore homeowners after install or after a full sanding-and-varnishing job.

The notes below apply to common Singapore parquet — Burmese teak, oak, walnut, merbau and similar hardwoods finished with a clear varnish. Some details (cleaning chemistry, recoat windows) differ slightly for unfinished oiled floors; if your floor is oil-finished, ask the contractor who installed it for their product-specific routine.

Daily and weekly care

The single biggest cause of premature varnish wear in Singapore homes is grit — fine sand and silica tracked in from outside that acts like sandpaper underfoot. A consistent daily-and-weekly routine handles 80% of the problem.

  • Doormats at every entrance. Coarse outside, soft inside. Most of the abrasive grit lands on the mat instead of the floor.
  • Soft sweep or microfibre dust mop daily in living and corridor areas. Vacuum with a soft floor head once or twice a week — never a beater bar. Beater bars and stiff bristles dull the varnish.
  • Damp microfibre mop once a week with the mop only slightly damp — wrung almost dry. Standing water and wet mopping are the second most common cause of swelling, lifting and white edges on parquet floors.
  • Wipe spills immediately. Water, juice, coffee — all of these can leave a stain or raise the wood grain if they are left to sit. A dry cloth first, then a damp wipe is enough for most spills.

Humidity — the Singapore-specific issue

Wood expands and contracts with moisture. In Singapore, swings between an air-conditioned bedroom at 24 °C and a non-aircon kitchen or balcony at 32 °C and 80% RH can cause noticeable cup, gap or crown on solid timber.

A practical target indoor range is 55-70% relative humidity with the air-conditioning used as you normally would. We do not recommend running a dehumidifier 24/7 — the goal is to avoid extremes, not to dry the wood out.

  • If the floor is cupping (edges higher than the centre of each board), the room is too humid or the floor got wet. Look for a leak, address it, then let the room dry out for a week or two before judging whether sanding is needed.
  • If the floor is gapping in the dry season (December to February for north-facing aircon-heavy rooms), it is usually self-correcting. Persistent gaps wider than 1.5 mm in solid wood may need board replacement or gap filling at the next sanding cycle.

Cleaning chemistry — what to use and what to avoid

The varnish on a parquet floor is the wear surface. Strong cleaners attack it long before they damage the wood underneath.

Use: A neutral wood-floor cleaner (Bona Wood Floor Cleaner, Pallmann Clean, or any pH-neutral product labelled for varnished wood). Dilute as the label says. A small amount applied to the mop — not poured on the floor — is enough.

Avoid: Vinegar (mildly acidic, etches varnish over time), bleach, ammonia-based glass cleaner, multi-surface degreasers, steam mops (the heat and water vapour swell the boards and lift the finish), wax (creates a sticky build-up that future recoats cannot bond to).

If you inherited a parquet floor and you are not sure what was used historically, switch to a pH-neutral cleaner immediately and accept that the first few wipes will look streaky as old residue lifts.

Furniture, rugs and pets

  • Felt pads under every chair, table and sofa leg. Inspect and replace them every six months — the felt traps grit and starts scratching the floor itself.
  • Rugs in high-traffic corridors add years to the varnish life between a sofa and a TV unit, or in front of a frequently-used dining chair.
  • Pet claws scratch varnish, especially water-based finishes. Keep claws trimmed; a runner in the dog's favourite corridor is a cheap insurance policy.
  • Rolling chairs in a study should sit on a hard-floor chair mat. Caster wheels will wear through any wood-floor varnish within a year or two of daily office use.

Screen-and-recoat vs full sanding

Varnish wears from the top down. Long before the wood is exposed, the varnish itself gets thin, dull or lightly scratched. At that point a screen-and-recoat — a light abrasion of the top coat plus one or two fresh coats of varnish — restores the finish at a fraction of the cost of a full sanding job.

  • When to screen-and-recoat: Varnish is dull, micro-scratches show under raking light, but no wood is exposed. Typically every 3-5 years for residential traffic.
  • When to fully sand: Wood is exposed in traffic lanes, there are dark water stains, boards have cupped or gapped, or the original varnish has flaked. Typical interval is every 10-15 years for residential parquet, sooner if the floor was abused.

Screen-and-recoat takes one day for a typical 3-bedroom condominium. Full sanding plus three coats of varnish takes three to five working days plus cure time. We confirm which one your floor needs at a free site inspection.

When to call a contractor

  • Persistent white edges, lifting strips, deep scratches into bare wood, or pet-urine black staining in the wood itself — these need spot board replacement or full sanding, not maintenance.
  • Squeaks that develop after years of use are usually loose boards or dried-out adhesive — addressed during a sanding cycle or by lifting and reseating specific boards.
  • Insect damage or rot — rare in well-maintained interior parquet, but if you suspect termite activity, get a pest-control sign-off before any flooring work begins.
