Wood Floor Restoration & Sanding: Technical Glossary
A-Z of Technical Entities
1. Acclimatisation: The process of allowing timber to reach its ‘equilibrium moisture content’ (EMC) within its final environment. This prevents excessive gapping or cupping after installation or restoration.
2. Bitumen Removal: A technical process of removing the black, tar-like substance often found on the edges of Victorian floorboards. Requires specialist Zirconia abrasives to prevent sandpaper ‘clogging’.
3. Bona Traffic HD: A high-performance, two-component (2k) water-based lacquer. It is the global standard for high-traffic commercial and residential areas, offering extreme scratch and chemical resistance.
4. Buffing: The mechanical process of using a rotary floor machine (like the Bona FlexiSand) with a fine-mesh screen or white pad to equalise the surface sheen and remove micro-imperfections between finish coats.
5. Chatter Marks: Rippled patterns left on a floor by poorly maintained or lightweight rental sanders. Professional Lagler Hummel machinery eliminates these through precision drum balancing.
6. Denibbing: A fine-sanding process performed between coats of lacquer or oil to remove ‘nibs’ (raised wood fibres or dust particles), ensuring a glass-smooth final surface.
7. Expansion Gaps: The intentional 10-15mm gap left around the perimeter of a room to allow the timber floor to expand and contract with seasonal West London humidity changes.
8. Gap Filling (Resin): Mixing fine wood ‘flour’ from the sanding process with a high-performance resin to create a colour-matched paste for sealing narrow gaps (up to 3mm).
9. Grain Raising: A phenomenon where wood fibres swell and stand up after the application of water-based products. This is managed through denibbing and proper sanding sequences.
10. Hardwax Oil: A premium finish (e.g., Osmo Polyx-Oil) that combines natural oils and waxes. It penetrates the wood for protection and provides a breathable, tactile surface layer.
11. Joist Stabilization: A structural repair involving the reinforcement of the timber beams (joists) beneath the floorboards to eliminate ‘bounce’ and creaking in period properties.
12. Moisture Content (MC): The amount of water contained in wood, expressed as a percentage. In the UK, indoor timber should typically be between 8-11% for a stable finish.
13. Osmo Polyx-Oil: The industry-leading hardwax oil finish, renowned for its tactile, organic feel and ease of local spot-repairs.
14. Parquet Re-stitching: The specialist process of replacing missing or damaged parquet blocks with matching reclaimed timber, ensuring the geometric pattern (e.g., Herringbone) is perfectly preserved.
15. Scalloping: An unsightly ‘dish’ or wave effect caused by improper use of an edging sander. Our master tradesmen prevent this through controlled, rhythmic tool movement.
16. Tannin Pull: A chemical reaction where natural acids (tannins) in woods like Oak react with water-based finishes, causing dark, bruised blotches. Prevented by using tannin-blocking primers.
17. Water Popping: The intentional application of water to raw, sanded wood to open the grain cells. This ensures deep, uniform penetration of stains and oils on dense hardwoods.
18. Zirconia Abrasives: High-performance sanding belts and discs used for heavy-duty levelling and the removal of stubborn historic finishes.
19. 2k Lacquer: A ‘two-component’ water-based finish (e.g., Bona Traffic HD) that utilizes a hardener for maximum resistance to chemicals, scratches, and heavy foot traffic.
