AH-12 Embossed Grey Oak 180mm Long Plank Engineered Flooring | AMUER
AH-12 is a 180mm long plank engineered oak floor with an embossed and chemically-treated surface finished in UV lacquer: 20/6mm multi-layer construction with a 6mm solid European oak wear layer over a stable multi-layer core, EF select grade, T&G installation. The embossment process mechanically presses deep, irregular grain relief into the board face, recreating the uneven surface of timber that has been walked on for decades, while the chemical treatment ages the natural oak tone toward a cool, driftwood grey-brown palette with darker mineral streaking through the grain. Together, these two surface treatments produce a floor that reads as reclaimed or antique oak rather than freshly milled timber. UV lacquer seals this deeply textured, weathered surface for durable, low-maintenance daily performance. AH-12 is available in stock from AMUER's Dalian China factory, giving buyers immediate access to a bold, rustic-industrial oak specification without factory production lead time.

Product Overview
Embossed & Chemically Treated Oak at 180mm — Deep Texture, Weathered Tone, Immediate Availability
AH-12's defining characteristic is the combination of two surface processes applied to a brushed EF grade oak base: embossment and chemical treatment. Embossment is a mechanical process that presses deep, irregular relief into the board face — far more pronounced than simple brushing — physically recreating the worn, undulating surface of antique or reclaimed timber that has endured decades of foot traffic. Chemical treatment is then applied to shift the natural warm oak tone toward a cooler, greyed palette, echoing the way oak naturally weathers when exposed to sun and moisture over time. The result is a driftwood-grey and taupe-brown surface with darker mineral streaking visible across the grain, delivering visual depth that reads as genuinely aged rather than artificially distressed.
AH-12's EF grading is itself a rustic, high-character specification — one of the most permissive grades in the AMUER range, with no restriction on the number of fresh or cracked-filled knots, dead knots up to 60mm, dark grain lines, and sapwood up to 30% of the board width. Mild natural blue-staining and mild rot markings are also permitted under EF grade, alongside natural discolouration across boards. This means AH-12's finished appearance draws on two compounding layers of character: a naturally varied, high-character oak base (EF grade) beneath the embossed and chemically-treated surface. Rather than a clean, uniform board given texture through surface treatment alone, AH-12 combines genuine natural grain variation with mechanical embossment and colour-ageing — producing one of the most authentically rustic, reclaimed-look specifications in the AMUER range.
UV lacquer completes AH-12 with a durable, sealed surface that locks in both the embossed texture and the weathered grey tone without altering their appearance. The satin sheen sits within the deep grain relief, catching light differently across the raised and recessed surfaces — in both natural daylight and artificial lighting, AH-12 reads as a floor with genuine spatial depth rather than a flat printed or stained surface.
The 20mm/6mm construction is a heavy-duty specification within the AMUER range: the 6mm solid oak wear layer supports multiple full sanding and refinishing cycles over the floor's service life, while the stable multi-layer core provides the dimensional stability required for T&G glue-down or nail-down installation — including larger commercial, hospitality, and retail projects where a fixed, non-floating floor is preferred over a floating click system.
Installation
Tongue & Groove Installation (T&G)
・Suitable for glue-down (full spread adhesive) or nail-down over a timber subfloor
・Subfloor flatness: 3mm per 2m maximum
・Expansion gap: minimum 12mm at all walls
・Acclimatisation: 48–72 hours before laying
・Stagger end joints: minimum 300mm
・Embossed grain channels: no filling required — this texture is part of the intended design
Underfloor Heating
・Compatible — maximum surface temperature 27°C. Maintain 45–60% RH year-round. UV lacquer is moisture-resistant and stable under UFH cycling. Activate UFH gradually after installation.
・6mm wear layer supports multiple full sanding and refinishing cycles over the floor's lifetime — note that full sanding will progressively reduce embossed texture depth over successive refinishes. Communicate this clearly to clients specifying AH-12 for long-term installation.
Room Suitability
| Room / Application | Suitability | Method | |||||
| Living Rooms | Exceptional | Weathered grey tone and deep embossed texture make a strong design statement. UV lacquer is durable for everyday residential use. | |||||
| Open Plan | Exceptional | The cool, aged tone works as a grounding neutral across large open-plan layouts without visual monotony. | |||||
| Hallways & Corridors | Exceptional | Embossed texture and UV lacquer resist and conceal daily wear exceptionally well — ideal for high-traffic zones. | |||||
Home Offices | Very Good | Durable, textured surface handles chair-castor traffic well; a protective mat is still recommended. | |||||
Dining Rooms | Very Good | UV lacquer resists spills; the deep grain texture helps mask everyday marks and scuffs. | |||||
Light Commercial | Very Good | T&G glue-down/nail-down installation and 6mm wear layer suit boutique hospitality and retail specification. | |||||
Kitchen (dry zone) | Good | UV lacquer resists splashes in dry areas. Avoid installation directly around the sink. | |||||
Bathrooms | Not Recommended | Not suitable for wet environments. | |||||
Care & Maintenance
| Task | Method | ||||
| Daily | Dry sweep or vacuum with soft brush head. Embossed grain channels collect fine grit — regular removal protects the UV lacquer surface and prevents abrasive wear within the textured grooves. | ||||
| Weekly | Damp mop with well-wrung cloth and pH-neutral UV lacquer floor cleaner only. No steam mop. No standard household cleaners. | ||||
| Spills | Wipe immediately. UV lacquer provides good spill resistance. | ||||
No re-oiling | UV lacquer requires no periodic re-oiling. Never apply wax or oil to AH-12 — adhesion failure with UV lacquer will result. | ||||
Wear layer care | 6mm wear layer supports multiple full sanding and refinishing cycles when needed — consult your installer regarding texture retention after sanding. | ||||
Never | Steam mop · standing water · wax or oil on UV lacquer · abrasive pads · ammonia or bleach-based cleaners. | ||||

FAQ
Q1. What is the difference between AH-12 and a standard brushed oak floor?
AH-12 has both embossment and chemical treatment applied over an EF grade oak surface, producing a deep, irregular textured relief and a cool, weathered grey-brown tone. A standard brushed oak floor has a lighter, more uniform surface texture and typically retains a warmer natural or lightly stained tone. Both may share UV lacquer finishing; the difference with AH-12 is the depth of surface relief and the deliberately aged, greyed colour treatment.
Q2. What does 20/6mm construction mean?
20mm is the total board thickness. 6mm is the solid European oak wear layer — a substantial specification that supports multiple full sanding and refinishing cycles over the floor's service life. The remaining depth is the multi-layer engineered core, which provides the dimensional stability required for T&G glue-down or nail-down installation.
Q3. Why is AH-12 installed with T&G rather than click?
T&G (tongue and groove) boards are installed using glue-down or nail-down methods rather than a floating click system. This suits projects requiring a fixed, permanent installation — common in commercial, hospitality, and larger residential projects — and pairs naturally with AH-12's heavier 6mm wear layer specification, which is engineered for long-term structural installation rather than a temporary or floating floor.
Q4. What is embossment and chemical treatment on engineered oak flooring?
Embossment is a mechanical process that presses deep, irregular texture into the board's surface, recreating the worn relief of reclaimed or antique timber. Chemical treatment is a separate wood-aging process that shifts the natural warm oak tone toward a cooler grey-brown palette. Applied together on AH-12, these processes produce a distinctive weathered, driftwood-grey appearance achieved through surface treatment rather than relying on bold natural grade character.
Q5. What does EF grade mean on AH-12?
EF is a rustic, full-character grade in the AMUER grading system — one of the most permissive specifications available. It places no limit on the number of fresh or cracked-filled knots, allows dead knots up to 60mm, permits visible dark grain lines and bark pockets (filled), sapwood up to 30% of board width, and even mild natural blue-staining, mild rot markings, and natural discolouration between boards. On AH-12, this naturally characterful oak base is then further transformed by embossment and chemical treatment, so the finished floor combines genuine natural grain variation with deliberate surface ageing — resulting in a floor with substantial, authentic rustic character at every level, from the raw timber grade through to the final surface finish.
Q6. Can AH-12 be used over underfloor heating?
Yes — AH-12 is compatible with both hydronic and electric UFH, maximum surface temperature 27°C. Maintain indoor humidity at 45–60% RH year-round. Activate UFH gradually after installation: increase 1–2°C per day to target temperature.
Q7. Can AH-12 be sanded and refinished?
Yes — AH-12 has a 6mm solid oak wear layer, which supports multiple full sanding and refinishing cycles over the floor's lifespan. Note that repeated sanding will gradually reduce the depth of the embossed texture, so refinishing intervals should be planned with this in mind for clients who value the original relief depth.
Q8. Is AH-12 available from stock?
Yes — AH-12 is a Dalian China factory stock product. Contact amuer@amuerflooring.com for current available quantities, pricing, and dispatch schedule.
