Timber Flooring Renovation Guide
Renovating timber flooring generally involves assessing the floor's structural condition, sanding down the damaged surface layer, filling gaps, and applying a protective topcoat.
Key Steps in Timber Floor Renovation
Inspection & Preparation
Check floor wear: Solid timber can be sanded multiple times, while engineered timber requires a real-wood top layer (wear layer) of at least 2–3 mm.
Punch down any raised nails below the wood surface and secure loose floorboards.
Clean thoroughly to remove grit, wax, and debris.
Sanding Process
Coarse Sanding (36–40 grit): Strips off old polyurethane, varnish, deep scratches, and stains.
Medium Sanding (60–80 grit): Smooths out rough sanding marks left by the coarse paper.
Fine Sanding (100–120 grit): Prepares the bare wood for stain or sealer absorption.
Gap Filling & Repairs
Mix fine sanding dust with a clear resin binder to create a matching filler for small gaps and nail holes.
Replace severely warped or water-damaged boards before final sanding.
Staining & Coating Options
Finish Type | Appearance | Durability & Maintenance |
Water-Based Polyurethane | Clear, non-yellowing, natural look | Low odor, fast drying (2–3 hours per coat), highly durable |
Oil-Based Polyurethane | Warm, amber tone | Strong protection, longer drying time (8–12 hours per coat), higher VOC odor |
Hardwax Oil | Matte/satin natural wood feel | Easy spot repairs, requires periodic re-oiling |
What is the average cost breakdown per square meter/foot to renovate existing timber floors?
The average cost to renovate an existing timber floor depends on whether you are refinishing (sanding and recoating) standard solid wood/parquet or replacing damaged timber boards.
Cost Overview per Measurement Unit
Service Type | Cost per Sq Ft (SGD) | Cost per Sq Meter (SGD) | Notes |
Standard Sanding & Polishing | $1.40 – $3.50 | $15 – $38 | Basic restoration using oil-based or standard varnish. |
Premium Refinishing | $3.50 – $6.50 | $38 – $70 | Includes deep repair, water-based non-toxic poly coating, or custom staining. |
Partial Board Replacement | $10 – $18 | $108 – $194 | Per square unit for patching severely damaged or warped areas. |
Full Timber Replacement | $12 – $25+ | $130 – $270+ | Hacking old floor, supply, and installation of solid/engineered hardwood. |
Detailed Itemized Cost Breakdown (Refinishing Existing Floors)
[Total Refinishing Budget: 100%]
├── Sanding & Surface Prep : 40% – 50% (Machining out scratches, old polyurethane, & leveling)
├── Coating & Finishing : 25% – 35% (Primer + 2-3 topcoats of oil/water-based polyurethane)
├── Repair & Gap Filling : 10% – 15% (Resin mixing, nail punching, & seam filling)
└── Site Logistics : 10% – 15% (Dust protection, moving light furniture, & cleanup)
Sanding & Surface Preparation (40% – 50% of cost): Covers multi-stage sanding with heavy drum sanders (from coarse 36-grit down to fine 120-grit).
Coating & Staining Options (25% – 35% of cost):
Oil-Based Polyurethane: Lower cost, amber warm finish, but higher odor/VOCs.
Water-Based Polyurethane: Premium cost (+20%–30%), clear matte/satin finish, fast-drying, low odor.
Wood Staining: Adding $0.80–$1.50 per sq ft ($8.50–$16 per sq m) if changing wood tone (e.g., walnut or teak tint).
Repairs & Gap Filling (10% – 15% of cost): Filling minor cracks using sanding dust mixed with resin filler. Individual damaged piece replacement runs $30–$50 per block/piece.
Common Add-on Costs to Factor In
Furniture Moving: $80 – $200 lump sum if the space isn't completely cleared.
Skirting Removal/Re-installation: $3 – $6 per meter.
Minimum Charge: Most contractors enforce a minimum project fee of $250 – $400 for single small rooms or spot repairs.
