Deep Grey Oak 90mm Chevron Engineered Flooring Chemical Treatment Embossed 15/4mm — AM-45
AM-45 is a 90mm deep grey chevron engineered oak floor in AB premium natural character grade, treated with embossment and chemical treatment, finished with UV lacquer: 15/4mm three-layer construction with a 4mm solid European oak wear layer over a cross-ply core, tongue-and-groove full-spread adhesive glue-down installation. The chemical treatment is the colour-defining process: it reacts with the natural tannins in the AB grade oak to produce a deep, penetrating cool grey that sits at a distinctly deeper and cooler register than grey stained floors — a grey that has blue-grey depth and complexity produced by the wood's own chemistry rather than applied pigment. The embossment accentuates the AB grade's gentle grain structure with a raised relief texture, ensuring the deep grey colour reads over a clearly natural wood surface in all lighting conditions. UV lacquer seals the chemical-treated embossed surface with a durable, stable film that locks in the deep grey permanently — no maintenance re-oiling, no colour drift. At 4mm wear layer and 15/4mm total thickness, AM-45 carries the most substantial construction in the AMUER T&G chevron range.

PRODUCT OVERVIEW
Deep Grey Chevron — Chemical Treatment, Embossment, 4mm Wear Layer
Chemical treatment vs staining — why it matters on AM-45. A grey stain applies a pigment to the wood surface, producing a colour that sits on the wood. Chemical treatment applies a solution that reacts with the tannins naturally present in the oak fibres, producing a grey that is in the wood — a penetrating colour that continues beneath the surface. The difference is visible: stained grey has a flatness of application; chemically treated grey has depth and natural complexity, because the tannin concentration varies from board to board and within each board, producing subtle shifts in grey depth that read as natural tonal movement across the floor rather than applied uniform colour. On AB grade oak, this variation is moderate and refined — a premium floor with depth and character rather than the extreme variation of a higher character grade.
Embossment on deep grey. The embossment treatment on AM-45 serves an essential role: on a deep grey surface, without surface texture the colour risks reading as flat, painted, or synthetic — a grey that obscures rather than reveals the wood. Embossment counters this by pressing the grain structure into a raised relief, so the deep grey reads over a clearly textured, clearly natural wood surface. In directional or raking light — morning sunlight from a window, angled track lighting — the embossed ridges catch lighter grey highlights and the channels hold deeper shadow, giving AM-45's deep grey surface a rich, layered visual depth that flat or brushed surfaces cannot achieve at this colour intensity.
4mm wear layer — the premium construction. AM-45's 15/4mm construction with a 4mm solid oak wear layer is the most substantial in the AMUER T&G chevron range. The 4mm wear layer supports 3–4 full sanding and refinishing cycles, making AM-45 a genuinely long-term investment floor. If the deep grey chemical treatment colour is ever sanded away, the floor can be refinished in a completely different colour or finish — including natural oil, UV lacquer in any colour, or wax oil — giving the 4mm wear layer genuine long-term specification flexibility.
Design Guide
AM-45's deep chemical grey, embossed grain texture, 90mm chevron, 4mm wear layer, and UV lacquer place it in the most architecturally considered and design-confident interior contexts.
Design-Led Contemporary & Minimalist
AM-45 is the floor for design-led contemporary interiors where depth of material specification is as important as aesthetic. The deep chemical grey reads as architecturally assured — not merely grey, but genuinely processed from the wood's own chemistry. Against white walls, concrete surfaces, and black or steel elements, the deep grey chevron reads as a precise, confident material statement.
Cool Japandi — Material Honesty
AM-45's chemical treatment produces a grey that is in the wood, not on it — the deepest alignment with Japandi's philosophy of presenting materials in their honest, undecorated form. The embossed texture confirms the wood's natural grain beneath the grey. Against warm white walls, dark ash joinery, and handmade ceramics, the deep grey chemical chevron grounds the interior with genuine material depth.
Dark Moody & Atmospheric
Against deep wall colours, AM-45's deep grey chevron creates an enveloping, low-contrast dark floor that adds depth without the warmth of dark brown or smoked oak. The deep grey and the deep wall colour create a sophisticated tonal layering — the floor is darker in mood than a pale grey but cooler in character than a dark smoked or brown floor.

Care & Maintenance
| Task | Method | ||
| Daily | Dry sweep or vacuum with soft brush head. Deep grey shows light dust and lint readily — regular sweeping is critical. The embossed grain channels collect fine grit; vacuum with soft brush attachment along grain direction. | ||
| Weekly | Damp mop with well-wrung cloth and pH-neutral UV lacquer floor cleaner only. No steam mop. No standard household cleaners. No standing water. | ||
| Spills | Wipe immediately. UV lacquer provides good spill resistance. Deep grey is relatively forgiving of everyday marks compared to pale floors. | ||
V-joints | Do not fill or caulk. Clean with soft vacuum brush along joint direction. | ||
No re-oiling | UV lacquer requires no periodic re-oiling. The chemical treatment colour is sealed permanently under UV lacquer — stable and will not shift with cleaning. | ||
Colour stability | The chemical-treatment grey on AM-45 is locked under UV lacquer and is more stable than wax-oil-finished chemically treated floors, which can lighten with UV exposure. AM-45's UV lacquer prevents this. Never apply wax, oil, or tinted maintenance products — incompatible with UV lacquer. | ||
Furniture | Felt pads under all furniture legs. Protective mat under desk chairs. | ||
Never | Steam mop · standing water · wax or oil · tinted maintenance products · ammonia or bleach cleaners · abrasive pads · filling chevron V-joints. | ||

FAQ
Q1. What is chemical treatment on oak flooring and how does it produce AM-45's grey?
Chemical treatment is a process where a solution is applied to the raw oak surface and reacts with the natural tannins present in the oak fibres, producing a colour change. Unlike staining, which applies a surface pigment, chemical treatment produces a colour that is in the wood — the result of the solution's chemistry interacting with the oak's own organic compounds. On AM-45, the chemical treatment produces a deep cool grey with a blue-grey undertone. The depth and exact tone of the grey varies subtly from board to board because tannin concentrations vary naturally in AB grade oak — producing a floor with natural tonal complexity rather than flat uniform grey colour.
Q2. How is AM-45 different from AM-44 (the other grey chevron)?
AM-44 uses a brushed-plus-saw-mark dual surface treatment over a grey stain — mid-grey, cross-textured, industrial aesthetic, UV lacquer, 15/4mm. AM-45 uses chemical treatment plus embossment — deeper grey, grain-direction texture, more architectural and material-honest aesthetic, UV lacquer, 15/4mm. AM-45's grey is deeper and has a more complex blue-grey undertone produced by chemistry rather than pigment; AM-44's grey is lighter and more cross-textured. Both are 4mm wear layer, T&G chevron, 90×510mm. Choose AM-44 for industrial, cross-textured grey; choose AM-45 for deep, architecturally complex grey.
Q3. Why does AM-45 use UV lacquer rather than wax oil on a chemical-treated floor?
UV lacquer on AM-45 is the correct finish for two important reasons. First, UV lacquer permanently seals the chemical-treatment grey colour, preventing the gradual lightening that can occur on chemical-treated wax oil floors with UV light exposure over time. The UV lacquer acts as a UV barrier, keeping the deep grey stable. Second, UV lacquer requires no periodic re-oiling — a significant practical advantage for a grey floor where maintenance oils could risk introducing warmth or tonal shift to the grey. The deep grey on AM-45 under UV lacquer is permanent, stable, and maintenance-simple.
Q4. Can AM-45 be sanded and refinished to a different colour?
Yes — the 4mm wear layer on AM-45 supports 3–4 full sanding cycles. Sanding AM-45 removes the chemical treatment colour and embossment texture, re-exposing raw oak. The sanded floor can then be finished in any specification — natural oil, UV lacquer in a different colour, wax oil, or another chemical treatment. This long-term refinishing flexibility is part of the value of the 4mm wear layer on AM-45.
Q5. Can AM-45 be used over underfloor heating?
Yes — compatible with hydronic and electric UFH at maximum 27°C surface temperature. Glue-down T&G is the most thermally stable installation for chevron over UFH. Allow 7 days for adhesive cure before UFH activation. Maintain 45–60% RH year-round. UV lacquer is more moisture-resistant than wax oil — an advantage over UFH.
