Christchurch Floor Sanding Market
Pre-earthquake Christchurch homes that survived often have original native timber floors. Post-earthquake rebuilds sometimes include engineered timber that can also be sanded. Christchurch's floor sanding market covers both heritage and modern flooring.
Can My Floor Be Sanded?
Native timber (rimu, kauri, matai, heart pine): Usually excellent candidates — thick boards that can be sanded multiple times over their lifetime.
Engineered timber: Can be sanded 1–3 times depending on the wear layer thickness (typically 3–6mm). Check the manufacturer specification.
Bamboo: Some bamboo floors can be sanded — depends on the product. Ask a professional to assess.
Parquet: Intricate parquet blocks can be sanded but require specialist care.
Cannot be sanded: Laminate flooring, most vinyl, and floors with less than 2–3mm of wood above the tongue.
Finish Options
Polyurethane (oil-based): Hard-wearing, amber tone, traditional look. 2–3 coats required. Dry time 24–48 hours per coat.
Water-based polyurethane: Clearer finish (less amber tone), faster drying, lower odour. More expensive but popular for light-coloured timber.
Hardwax oil: Natural look, penetrating finish. Easier spot repairs than surface finishes but requires more maintenance.
Staining: Apply a colour stain before the topcoat to change the floor tone. Popular for darkening lighter timber or creating a modern grey/charcoal look.

Frequently Asked Questions
How much does floor sanding cost in Christchurch? Sand and finish (3 coats polyurethane): $30–$58/m²/m². Full 3-bed home (~80m²): $2,200–$5,500.
How long does floor sanding take? A standard 3-bed home: 2–3 days (sanding + 3 coats of finish with drying time). The home needs to be vacated during sanding (dust) and for 24–48 hours after the final coat.
