The Mark of the Hand -- AC-23 at 260mm
AC-23 is a 260mm extra-wide engineered oak floor in a 15/4mm three-layer construction with a 4mm solid oak wear layer, hand scraped, ammonia fumed, and finished in penetrating wax oil. The hand scraping is applied at exceptional density — crescent marks packed tightly across the full 260mm board face, each one the record of a single stroke of a cabinet scraper blade: entry, arc, exit, leaving a shallow depression with slightly raised edges. At distance the surface reads as almost scaled or woven; at close range it resolves into hundreds of individual impressions, each slightly different in pressure, angle, and depth. No manufacturing process produces this. Every mark visible in the product photograph was made by a person.
Ammonia fuming follows the scraping, and the sequence matters. On a hand-scraped surface the fuming reacts differently across the micro-topography: the burnished ridges left by the blade edge take a lighter tone, while the valley floors — exposing fresh wood fibre — absorb the deeper smoked colour. The result is a warm grey-brown field with subtle tonal variation at the scale of individual scraper strokes, visible at close range as a surface that shifts slightly in tone with the light. Wax oil finish completes the specification: penetrating rather than film-forming, it deepens and stabilises the smoked colour while preserving the full tactile depth of the scraped texture — every ridge and valley felt underfoot, nothing sealed away behind a surface layer. The photograph shows the marks. The sample shows the depth. The installed floor shows the warmth.
Design Guide
AC-23's hand-scraped smoked wax oil surface and warm grey-brown tone point toward specific interior contexts where tactile authenticity and material depth are valued above convenience. Two contexts where AC-23 is the definitive choice:
Scholarly & Contemplative
AC-23 is the floor of choice for interiors of serious intellectual purpose: the study lined with books, the library with leather chairs, the private office with aged timber. The hand-scraped smoked wax oil surface references the floors of old institutions -- universities, country houses, legal chambers -- that have developed their patina over generations. Against dark wood furniture, leather upholstery, and aged paper, AC-23 provides the floor that belongs.
Arts & Crafts Heritage
The Arts and Crafts movement celebrated the mark of the maker's hand -- the texture left by the craftsperson as a record of their skill and presence. AC-23's dense hand-scraped surface is the contemporary engineered floor that most faithfully references this philosophy. Against original joinery, Morris-inspired textiles, handmade ceramics, and exposed brickwork, AC-23 is the floor that shares the values of its architectural context.
Installation & Room Suitability
Click Installation (Floating)
AC-23 uses Uniclic-compatible click floating installation. The 260mm extra-wide format requires careful subfloor preparation. The wax oil finish means the floor must acclimatise fully before installation.
•No adhesive required -- click lock floating installation
•Subfloor flatness: 3mm per 2m maximum -- essential for 260mm boards
•Expansion gap at all walls: minimum 15mm
•48-hour acclimatisation at room temperature before installation
•Install perpendicular to room entry for best appearance
•Stagger end joints: minimum 400mm between rows
Use foam or combination underlay appropriate for wax oil floors
Underfloor Heating
AC-23 is compatible with UFH. Wax oil handles UFH thermal cycling well -- it does not crack under heat stress as lacquer can. Extra-wide 260mm boards require careful humidity management.
✓Maximum surface temperature: 27 degrees C
✓Switch off heating 48 hours before installation
✓Restart gradually: 1-2 degrees C per day to operating temperature
✓Maintain indoor humidity 45-60% RH year-round
✓Wax oil handles UFH cycles without cracking or surface failure
Thermal resistance 0.15 m2 K/W maximum
Room Suitability
| Room / Application | Suitability | Notes |
| Living Rooms | Excellent | The tactile depth and warm grey-brown smoked tone create an interior of exceptional material quality. The wax oil surface feels and looks genuinely aged. |
| Dining Rooms | Excellent | At eye level from a seated position, the dense crescent scraper marks are fully visible and reward close attention. The ideal room for AC-23's surface detail. |
Studies & Libraries | Excellent | Hand-scraped smoked wax oil oak is the floor of choice for scholarly, contemplative, and craft-focused interiors. The surface references aged library floors and study floorboards. |
Heritage & Period Buildings | Excellent | AC-23's surface quality is the closest of any new engineered product to genuine aged and patinated timber. Works in Georgian, Victorian, Arts and Crafts, and farmhouse interiors. |
Master Bedrooms | Excellent | Warm grey-brown smoked tone and soft wax oil surface create a rich, intimate bedroom environment. The texture is softer underfoot than lacquered floors. |
Hallways | Very Good | Wax oil is more repairable than lacquer for hallway use -- scuffs and marks in high-traffic zones can be locally refinished. Re-oil hallway areas annually. |
Kitchen | Good | Wax oil is not as water-resistant as lacquer. Seal board joints at installation. Wipe spills immediately. Re-oil kitchen areas annually. Not ideal for very wet kitchen workflows. |
Hospitality -- Bespoke | Very Good | For design-led hospitality properties that value tactile authenticity, AC-23 is a premium specification. Note: wax oil requires more maintenance than lacquer for commercial use. |
Bathrooms | Not Recommended | Not suitable for persistent moisture -- specify SPC flooring for wet rooms. |
Care & Maintenance -- Wax Oil on Hand Scraped Smoked Surface
| Task | Method |
| Daily | Dry sweep or vacuum with soft brush head -- the dense hand-scraped valleys collect fine dust effectively; vacuum along the crescent pattern if possible or in grain direction |
| Weekly | Damp mop with well-wrung cloth and pH-neutral wood floor cleaner suitable for oiled floors -- no standing water; wax oil is not fully waterproof |
| Spills | Wipe immediately -- wax oil is not as water-resistant as lacquer; standing spills risk staining the open wood fibre; the smoked tone makes spills less visible than on pale floors -- check regularly |
Spot repair | Lightly abrade the worn or marked area with 240-grit paper along the grain direction and re-apply wax oil locally -- no need to refinish the entire floor; the hand-scraped texture makes local repairs blend naturally |
Full re-oil | Every 1-3 years depending on traffic -- use AMUER Floor Care Wax Oil or a compatible hardwax oil; the hand-scraped texture absorbs oil well and the re-oiling process is particularly effective on this surface |
Never | Never Steam mop · abrasive cleaners · bleach · solvent-based products · UV lacquer products · re-lacquering (wax oil floor -- never apply lacquer over wax oil) |

FAQ
Q1. What is hand scraped smoked oak engineered flooring?
Hand scraped smoked oak engineered flooring is a multi-layer engineered hardwood floor with a solid oak wear layer that has been processed with both a hand scraping step -- in which a skilled worker draws a cabinet scraper across each board face to create dense crescent marks and three-dimensional undulations -- and an ammonia fuming step that permanently colours the wood a warm grey-brown without pigment or stain, finished with wax oil.
AMUER AC-23 is 260mm wide, 2,200mm long, 15/4mm total thickness with a 4mm solid oak wear layer, CD natural character grade, hand scraped and smoked surface, wax oil finish, and click installation. It is the most tactile and labour-intensive surface treatment in the AMUER 260mm smoked range, combining two processes that each derive from pre-industrial timber-working traditions.
Q2. What does hand scraped oak flooring look like and feel like?
Hand scraped oak flooring looks like a field of dense crescent and arc marks across the board face -- the record of each scraper stroke is visible as a shallow depression with slightly raised edges, packed tightly across the full board width; from a distance the pattern reads as almost scaled or woven; close-up each individual mark is distinct.
Underfoot and to the touch, hand scraped oak flooring feels like a three-dimensional surface with perceptible ridges and valleys at the scale of individual scraper strokes. In AC-23, this texture is sealed with wax oil rather than lacquer, which means the full tactile depth of the scraped marks is preserved -- there is no hard surface film filling the valleys. The floor feels warm, organic, and genuinely hand-made.
Q3. What is the difference between hand scraped and brushed smoked oak?
Hand scraped smoked oak (AC-23) has a dense, irregular crescent-mark texture created by a person with a scraper blade; the smoked colour settles differently in the marks' ridges and valleys for a warm grey-brown tone; wax oil finish preserves the tactile depth. Brushed smoked oak (AC-09, AC-22) has a directional open-grain texture created mechanically; the smoked colour is amber-tobacco or warm gold-brown; UV lacquer finish provides a hard surface.
The practical differences: hand scraped wax oil requires periodic re-oiling (every 1-3 years) and delivers the deepest tactile character; brushed UV lacquer requires no periodic oiling and delivers a hard, durable surface. AC-23 is chosen when the floor's tactile and visual character is the primary design requirement; AC-09 or AC-22 when durability and maintenance convenience are prioritised.
Q4. Why is wax oil used on AC-23 rather than UV lacquer?
Wax oil is used on AC-23 because a hard lacquer surface film would fill the valleys of the hand-scraped texture and reduce the three-dimensional tactile depth that the hand scraping is designed to create -- wax oil penetrates the wood fibre without forming a surface film, preserving every ridge, valley, and crescent mark as a fully tactile surface feature.
This is the fundamental difference in finish philosophy between AC-23 and the UV lacquer smoked products: lacquer seals and protects at the cost of tactile character; wax oil preserves tactile character at the cost of maintenance requirement. For a floor specified specifically for its hand-made tactile authenticity, wax oil is the finish that fully honours the process.
Q5. Can AC-23 be used over underfloor heating?
Yes -- AC-23 is compatible with both hydronic and electric underfloor heating, with a maximum recommended surface temperature of 27 degrees C.
Wax oil handles UFH thermal cycling well -- it does not crack under heat stress as lacquer can. At 260mm extra-wide, maintain indoor relative humidity at 45-60% RH year-round. Switch off heating 48 hours before installation and restart gradually, increasing by 1-2 degrees C per day.
Q6. How do I maintain the wax oil finish on AC-23?
Wax oil on AC-23 requires periodic re-oiling every 1-3 years with a compatible hardwax oil -- plus daily sweeping, weekly damp mopping with a pH-neutral wood floor cleaner, and prompt spill wiping, as wax oil is not as water-resistant as lacquer.
The practical maintenance advantage of wax oil on a hand-scraped floor: spot repair is straightforward -- lightly abrade the worn area with 240-grit paper along the grain and re-apply wax oil locally. The hand-scraped texture means local repairs blend naturally into the surrounding surface variation, making spot repair more effective than on a smooth floor. Full re-oiling every 1-3 years refreshes the entire surface and deepens the smoked tone.
Q7. Can AC-23 be sanded and refinished?
Yes -- AC-22 has a 4mm solid oak wear layer supporting 3-4 full sanding and refinishing cycles over the floor's lifespan.
After sanding, AC-22 can be re-fumed at the appropriate lighter intensity and re-finished with UV lacquer to restore the warm brown-gold smoked appearance. Alternatively, after sanding, the floor can be finished with a different treatment if a different tone is preferred. Full refinishing requires professional equipment and should be carried out by a flooring specialist.
Q8. What is the minimum order for AC-23?
The standard minimum order for AMUER AC-23 is 200 m2 per SKU from our China factory.
