AB Select Brushed Oak Chevron Engineered Flooring UV Lacquer — AM-40
AM-40 is a 90×510mm engineered oak chevron floor in AB select grade with a brushed surface and UV lacquer finish: 15/4mm 3-layer construction with a 4mm solid European oak wear layer, tongue-and-groove (T&G) installation. The chevron pattern — each stave cut at a precise 45° mitre so board ends align to form a continuous V-arrow formation across the room — is one of the most architecturally refined parquet patterns available, distinct from herringbone in its unbroken diagonal arrow movement across the floor.
AM-40's cool greige tone — the natural European oak lightly enhanced by the brushed surface and UV lacquer — positions it at the contemporary, design-led end of the oak colour spectrum: neither the warm honey-gold of natural untreated oak nor the stark cool of heavily bleached floors, but a refined, neutral greige that works across the full range of contemporary interior palettes. The AB select grade delivers clean, consistent boards with minimal knot variation — appropriate for a pattern floor where the visual focus is on the geometric formation rather than individual board character. The brushed surface adds a fine tactile grain relief without disrupting the chevron pattern's clean geometry.

Full Product Specification
| Specification | AM-40 Detail |
| Product Code | AM-40 |
| Species | Top layer European Oak ; Poplar core and backing layer |
| Construction | 3-Layer Engineered Wood Flooring — cross-ply solid timber core for dimensional stability |
Total Thickness | 15mm |
Top Layer | 4mm solid European oak — the thickest wear layer in the AMUER oak chevron range; supports 2–3 sanding and refinishing cycles |
Stave Dimensions | 90mm wide × 510mm long — precision mitre-cut at both ends for chevron assembly; each stave is an exact mirror-image pair (left and right hand) that assembles into the continuous V-arrow chevron pattern |
Pattern | Chevron — each stave cut at 45° at both ends; board ends align precisely so the joint runs in a continuous unbroken diagonal line across the floor, forming a repeating V-arrow (chevron) formation; distinguished from herringbone by the continuous unbroken diagonal joint and the sharper, more directional arrow movement |
Colour | AM-40 Greige Oak — cool warm greige; the natural European oak base colour with a subtle cool shift from the brushed surface treatment under UV lacquer; neither warm honey-gold nor cool grey but a refined neutral greige with warm undertones; AB grade delivers consistent board colour with minimal sapwood-to-heartwood variation; the greige tone reads as sophisticated, contemporary neutral — compatible with cool and warm interior palettes |
Surface Treatment | Brushed — wire or nylon brushes remove soft early-wood fibres to expose the harder late-wood grain lines in tactile relief; on chevron staves, the brushed texture follows the grain direction within each stave, creating a consistent micro-texture across the assembled pattern; the brushing adds depth and shadow to the greige colour without disrupting the precision of the chevron geometry |
Finish | UV Lacquer — hard, clear factory-applied finish; seals and protects the brushed surface and greige colour; scratch and stain resistant; easy daily maintenance; no periodic re-oiling required; the UV lacquer sheen is controlled and matte on the brushed surface, producing a refined, contemporary appearance appropriate for the chevron pattern format |
Grading | AB — Select Grade: tight or absent knots; minimal open grain variation; very low sapwood content; consistent clean board appearance; AB grade is the correct specification for chevron pattern floors where visual uniformity across the geometric pattern is the priority — excessive character variation in CD or DEF grades can disrupt the reading of the chevron formation |
Edge Profile | Square Edge — flush stave-to-stave joint within each chevron row; the 45° mitre cut is precise and clean; no bevel required on the face edges |
Installation | T&G (Tongue & Groove) — traditional glue-down installation; full-spread adhesive to subfloor; recommended for herringbone pattern for maximum stability |
Underfloor Heating | Compatible — maximum surface temperature 27°C; maintain 45–60% RH year-round; UV lacquer stable under heating cycles; use flexible adhesive for glue-down installations with UFH |

TPRODUCT OVERVIEW · AM-40 CHEVRON OAK
AM-40 is built around the chevron pattern's defining visual quality — the continuous unbroken diagonal joint that creates a strong, directional arrow movement across the room — and the AB select greige oak colour that positions this geometric pattern firmly in the contemporary design spectrum.
The stave dimension of 90×510mm is the classic chevron proportion: the 1:5.67 width-to-length ratio produces a chevron formation with the correct visual scale for room-sized installations — wide enough that the individual staves read as substantial planks within the pattern, long enough that the V-arrow formation reads with clarity and movement across the floor. At 90mm wide, the assembled chevron has a rhythm that works from living room to hallway scale; at 510mm long, each stave contributes a generous diagonal movement to the overall formation.
The AB select grade is the correct grading for AM-40. Chevron is a geometric pattern floor: the visual focus is on the formation itself — the continuous diagonal joint, the V-arrow movement, the interplay of grain direction across the assembled pattern. Excessive board-to-board character variation in lower grades (CD, DEF) can disrupt this reading, introducing colour and knot variation that competes with the pattern geometry. The AB select grade of AM-40 delivers consistent, clean boards where the grain direction within each stave reads as a contribution to the pattern rather than an independent character statement.
The greige colour amplifies this design clarity: cool enough to read as contemporary and design-led, warm enough to avoid coldness, and neutral enough to work as a foundation for virtually any interior palette. The brushed grain adds tactile depth without visual noise. The UV lacquer seals and protects the whole assembly with a controlled matte sheen appropriate for the pattern format.
Design Guide
AM-40's cool greige AB select colour, strong chevron geometry, brushed grain texture, and UV lacquer finish place it across contemporary, design-led, and Japandi-influenced interior contexts:
Contemporary Minimal & Japandi
AM-40's greige chevron is the floor specification for Japandi and warm minimalist interiors: the geometric pattern adds architectural interest, the greige colour works with pale walls and natural materials, and the AB select consistency ensures the pattern reads clearly without character variation competing with the geometry. The chevron directs the eye across the room, elongating and ordering the space.
Design-Led Residential & Architect Specification
For architects and interior designers specifying a premium engineered floor with geometric pattern interest, AM-40's chevron formation, AB select precision, 4mm wear layer, and UV lacquer durability deliver the design aesthetic and technical performance required for high-end residential projects. The greige tone sits neutrally within virtually any material and colour palette.
Classic French & European Parquet
Chevron is a classic European parquet pattern associated with the grand floors of Parisian apartments, French châteaux, and Georgian townhouses. AM-40's AB select greige in UV lacquer offers this classic pattern in a practical modern format — the greige tone bridges the historical pattern with a contemporary colour, producing a floor that reads as both classic and current.
T&G Installation — Chevron Pattern Laying Guide
Glue-Down Installation (Recommended)
Full glue-down is the standard installation method for T&G chevron engineered flooring. The flexible adhesive provides a rigid, stable base for the precision pattern alignment required for chevron.
· Subfloor: concrete screed, sand-cement, or timber — must be dry, flat, and structurally sound
· Flatness: 3mm per 2m maximum — more critical for chevron than long plank; any subfloor undulation disrupts pattern alignment
· Adhesive: flexible polyurethane or MS polymer adhesive; full spread trowel application across entire stave back
· Starting point: establish the chevron apex point at the room centre or focal wall; snap chalk lines at 45° to establish the layout before laying first staves
· Left and right hand staves: chevron staves are mirror-image pairs; confirm L/R orientation before beginning each row
· Press and weight staves during adhesive cure; use tapping block on T&G joint — never strike stave face
· Expansion gap: 10mm minimum at all walls; cover with skirting or threshold strip
· Allow adhesive to cure fully (minimum 24 hours) before light foot traffic; 48–72 hours before normal use
Underfloor Heating
AM-40 is compatible with both hydronic and electric UFH with glue-down installation.
· Maximum surface temperature: 27°C
· Use flexible polyurethane adhesive for UFH installations — allows for thermal movement
· Switch off heating 48 hours before installation; restart gradually at 1–2°C per day
· Maintain 45–60% RH year-round
· Thermal resistance: 0.15 m²K/W maximum
Nail-Down & UFH Considerations
Nail-down installation is suitable for AM-40 over a timber subfloor only (minimum 18mm structural grade plywood or hardwood boards).
· Use engineered hardwood cleats or staples at 200–250mm spacing along the T&G groove
· Not suitable for concrete subfloor — use glue-down for concrete
Room Suitability
| Room / Application | Suitability | Notes | |
| Design-Led Living Rooms | Excellent | The chevron pattern's strong directional arrow movement creates a bold geometric statement in living rooms. The greige AB select colour works with the full contemporary palette. Install with the chevron apex pointing toward the main focal point (fireplace, feature wall) for maximum visual impact. | |
| Master Bedrooms | Exceptional | Chevron engineered flooring in AB select greige is a popular specification for master bedrooms in design-led residential projects. The pattern adds architectural interest without the colour drama of darker floor treatments. The UV lacquer is low-maintenance in a bedroom context. | |
Dining Rooms | Excellent | The chevron formation creates a defined dining area and adds geometric interest to the dining room floor. UV lacquer resists food and drink spills effectively. | |
Entrance Halls & Landings | Excellent | Chevron is classically specified for entrance halls and landings where the directional arrow movement of the pattern guides movement through the space. Install with the apex pointing down the hall for maximum effect. | |
Home Offices & Studies | Excellent | AB select greige chevron creates a refined, focused working environment. UV lacquer is durable and easy to maintain. | |
Boutique Hospitality & Commercial | Very Good | AM-40's UV lacquer durability and precision AB select appearance make it suitable for boutique hotel rooms, restaurant private dining, and premium office environments. T&G glue-down provides the stability required for commercial foot traffic. | |
Open-Plan Kitchen-Living | Good | Chevron works well in open-plan spaces as a unifying floor pattern. UV lacquer handles kitchen spill environments effectively; the greige tone is forgiving of the warm and cool palette combinations typical in open-plan spaces. | |
Bathrooms | Not Recommended | Not suitable for persistent moisture exposure. | |
Care & Maintenance — Brushed Oak Chevron UV Lacquer
| Task | Method | ||
| Daily | Dry sweep or vacuum with soft brush head. For chevron pattern floors, sweep diagonally along the stave direction (45° to the room walls) or along the central spine of the chevron to avoid pushing debris into the cross-joints. The greige colour shows dark grit and fine dust clearly — regular sweeping maintains the pattern's clean appearance. | ||
| Weekly | Damp mop with well-wrung cloth and pH-neutral hardwood floor cleaner. UV lacquer is fully sealed — no risk to the brushed surface or greige colour from normal damp mopping. No steam mop, no standing water. Clean in the direction of the individual stave grain, not across the joints. | ||
| Spills | Wipe immediately with a dry cloth. UV lacquer resists household liquids effectively. Prompt action prevents penetration at stave joints — the multiple joints of the chevron pattern create more joint length per square metre than long plank, so prompt spill response is more important. | ||
Joint care | The 45° mitre joints of the chevron pattern accumulate fine dust and debris more readily than long plank joints. Vacuum with a soft brush attachment along the joint lines periodically to keep the pattern joints clean and clearly defined. | ||
Periodic maintenance | UV lacquer requires no periodic re-oiling. Buff with manufacturer-approved hardwood floor polish every 6–12 months to restore surface sheen and protection across the full chevron pattern. | ||
Scratches | Minor surface scratches: manufacturer-matched UV lacquer repair pen. For chevron pattern floors, colour-match to the specific greige of AM-40. Deep scratches through the lacquer require professional repair — individual stave replacement or spot sanding and lacquer recoating. | ||
Never | Steam mop · standing water · abrasive scrubbers · bleach or acid cleaners · oil or wax products on lacquered surface · silicone-based polishes · dragging heavy furniture across chevron joints. | ||

FAQ
Q1. What is engineered oak chevron flooring?
Engineered oak chevron flooring is a parquet pattern floor made from precision mitre-cut engineered oak staves — each stave cut at 45° at both ends — that are assembled in mirror-image left and right hand pairs to form a continuous V-arrow (chevron) formation across the room. AM-40 uses 90×510mm staves in AB select brushed European oak with UV lacquer finish, T&G tongue-and-groove profile, and 15/4mm 3-layer construction with a 4mm wear layer. The chevron pattern is distinguished from herringbone by its continuous unbroken diagonal joint, which creates a stronger, more directional arrow movement across the floor.
Q2. What is the difference between chevron and herringbone flooring?
Chevron and herringbone are both diagonal parquet patterns but differ in their stave geometry and visual effect. Chevron staves are cut at 45° at both ends (mitre cut), so when assembled, the stave ends align perfectly to form a continuous unbroken diagonal joint running across the full floor — producing a strong, continuous V-arrow movement. Herringbone staves are square-cut (perpendicular ends); each stave end meets the side of the next stave, creating a broken staggered joint and a more traditional zigzag rhythm. Chevron reads as more architectural and directional; herringbone reads as more classic and textural.
Q3. Does T&G chevron flooring need to be glued down?
Yes — T&G (tongue-and-groove) chevron flooring is typically installed by full glue-down to the subfloor or nail-down to a timber subfloor. T&G is not a click-floating system; the staves are interlocked via the tongue-and-groove profile and secured by adhesive or cleats. Full glue-down with a flexible polyurethane or MS polymer adhesive is the recommended installation method for AM-40 on concrete or screeded subfloors. Nail-down is suitable for timber subfloors. Floating installation is not recommended for T&G chevron pattern flooring as it does not provide the stability required for precision pattern alignment.
Q4. Which direction should chevron flooring be installed?
The chevron pattern should typically be installed with the apex point (the V-point) oriented toward the main focal feature of the room — a fireplace, feature wall, large window, or doorway. This directs the arrow movement of the pattern toward the visual focus and creates the strongest elongating effect along the room's main axis. Before installation, establish the chevron layout by snapping chalk lines at 45° to the room walls from the chosen centre or focal point, and dry-lay the first staves to confirm the pattern reads correctly across the full room before applying adhesive.
Q5. Can AM-40 chevron flooring be used over underfloor heating?
Yes — AM-40 is compatible with both hydronic and electric underfloor heating with glue-down installation. Use a compatible flexible polyurethane adhesive that accommodates thermal movement. Maximum surface temperature 27°C. Maintain indoor humidity at 45–60% RH year-round. Switch off heating 48 hours before installation; restart gradually at 1–2°C per day. UV lacquer is stable under UFH heating cycles.
Q6. Why is AB grade recommended for chevron pattern flooring?
AB grade is recommended for chevron and other parquet pattern floors because the visual focus of a pattern floor is on the geometric formation itself — the precision alignment of the chevron joints, the continuous diagonal movement, the interplay of grain direction across assembled staves — rather than on individual board character. Excessive character variation in lower grades (CD, DEF) with open knots, checks, and strong colour variation can disrupt the reading of the pattern by introducing visual noise that competes with the geometry. AB select grade delivers consistent, clean boards where the grain and colour contribute to the pattern's clarity and uniformity.
