Pearl Grey at 260mm -- The Most Contemporary Floor in the AMUER Range

AM-19 is a 260mm extra-wide plank engineered oak floor in pearl grey with a saw mark surface and UV lacquer finish, offering the coldest and most architecturally contemporary tone in the AMUER engineered hardwood range. Constructed as a 15/4mm three-layer engineered floor with a 4mm oak wear layer, the floor achieves its pale grey-silver appearance not through surface staining, but through the saw mark process itself. Fine parallel saw cuts expose the cooler inner fibres of the European oak, creating a naturally pale grey texture across the board surface, while the UV lacquer seals the color with a durable low-sheen finish that requires no periodic maintenance.

At 260mm wide, AM-19 creates an exceptionally seamless visual effect with minimal board joints, allowing the floor to read almost as a continuous architectural surface rather than individual planks. This makes it especially suited to contemporary minimalist, industrial, and modern architectural interiors where the floor functions as a calm spatial backdrop. The CD grade introduces moderate natural character — including medium tight knots and flowing grain variation — which appear as subtle grey-brown features against the pale surface, adding depth and authenticity without disrupting the clean overall appearance.

Design Guide

AM-19's pearl grey tone and saw mark texture are the most architecturally specific in the AMUER range -- they point strongly toward particular interior aesthetics. Three contexts where AM-19 is the definitive floor choice:

Industrial Heritage

In industrial-heritage conversions -- warehouses, factories, loft buildings -- AM-19's saw mark texture echoes the machine aesthetic of the architecture. The cool grey tone picks up the grey of weathered concrete, exposed steel beams, and factory glazing. The wide 260mm boards match the industrial scale of the space. Against warm brick and aged timber, the pale grey floor provides contrast without conflict.

Dark Sophisticated

The most unexpected application of AM-19: as a pale floor in a dark, moody interior. Deep charcoal walls, forest green panelling, dark velvet upholstery, and warm candlelit lighting -- against all of these, the pearl grey floor glows as the lightest element in the room, providing contrast and spatial grounding. The saw mark texture reflects ambient light softly across the grey surface.

Installation & Room Suitability

Click Installation (Floating)

AM-19 uses Uniclic-compatible click floating installation. The 260mm extra-wide board format requires meticulous subfloor preparation -- any unevenness is amplified across the wider board.

•No adhesive required -- click lock floating installation

•Subfloor flatness: 3mm per 2m maximum -- critical for 260mm boards; check and level carefully

•Expansion gap at all walls: minimum 15mm (wider gap required for 260mm format)

•48-hour acclimatisation at room temperature before installation

•Install perpendicular to room entry for optimal visual effect

Stagger end joints: minimum 400mm between adjacent rows

Underfloor Heating

AM-19 is compatible with both hydronic and electric UFH. Extra-wide boards require careful humidity management -- 260mm boards have more potential for edge movement than narrower planks.

✓Maximum surface temperature: 27 degrees C (hydronic and electric)

✓Switch off heating 48 hours before installation

✓After installation: increase 1-2 degrees C per day to target temperature

✓Maintain indoor humidity 45-60% RH year-round -- tighter range for 260mm

✓UV lacquer handles UFH cycles without risk of cracking or delamination

Thermal resistance 0.15 m2 K/W maximum

Room Suitability

Room / Application	Suitability	Notes
Contemporary Open Plan	Excellent	260mm grey oak creates an architectural floor plane in open-plan spaces. The pale cool tone and saw mark texture read as a continuous grey surface at distance.
Living Rooms	Excellent	The most architecturally impactful floor in the AMUER range. Grey tone works with any dark, white, or concrete palette.
Bedrooms	Excellent	Cool, pale tone creates a sophisticated, calming bedroom environment. Less warm than natural oak but visually refined.
Home Offices / Studios	Excellent	Grey tone provides a focused, neutral environment. UV lacquer suits desk chair use with mat.
Hallways	Very Good	Extra-wide boards make hallways feel more expansive. UV lacquer durability handles traffic well.
Kitchen	Good	UV lacquer more water-resistant than oil. Seal all board joints. Wipe spills promptly.
Commercial & Retail	Excellent	260mm grey oak at UV lacquer quality is a premium commercial floor specification -- works in gallery, retail, and office contexts.
Hospitality -- Rooms & Suites	Very Good	Cool grey tone creates a design-forward hotel room. Suits properties targeting a contemporary guest profile.
Bathrooms	Not Recommended	Not suitable for persistent moisture -- specify SPC flooring for wet rooms.

Care & Maintenance — UV Lacquer on Saw Mark Surface

Task	Method
Daily	Dry sweep or vacuum with soft brush head -- no beater bar. Note: pale grey surface shows dust and footprints more readily than warm dark floors; regular sweeping is especially important
Weekly	Damp mop with well-wrung cloth and pH-neutral lacquered floor cleaner -- no standing water. Pale surface may show cleaning product residue; rinse with clean water
Spills	Wipe immediately -- UV lacquer is more water-resistant than oil but standing coloured liquids (wine, coffee, juice) risk permanent staining if left on pale grey surface
Saw mark texture	The saw mark striations may collect very fine dust in the valleys -- a soft brush head vacuuming along the grain direction clears this most effectively
Deep cleaning	Use manufacturer-recommended lacquered floor cleaner annually -- do not use abrasive pads or bleach-based products, which may affect the pale tone
Never	Steam mop · abrasive cleaners · bleach · solvent-based products · oil products (will cloud or stain lacquer) · re-oiling (lacquered floor, not oiled)

FAQ

Q1. What is pearl grey engineered oak flooring?

Pearl grey engineered oak flooring is a pale, cool grey-toned engineered hardwood floor in which the grey colour is achieved through a saw mark surface treatment that exposes the paler inner fibres of the European oak beneath the natural amber surface tone, sealed with UV lacquer for a hard-wearing, low-maintenance finish.

AMUER AM-19 is 260mm wide, 2,200mm long, 15/4mm total thickness with a 4mm solid European oak wear layer, CD natural character grade, saw mark surface treatment, UV lacquer finish, and click installation. It is the most architecturally contemporary colour in the AMUER engineered range -- a cool grey-silver that works with concrete, black steel, white walls, and dark dramatic palettes.

Q2. What is saw mark surface treatment on oak flooring?

Saw mark surface treatment creates fine parallel mechanical striations across the face of each oak board by drawing circular saw blades across the wood surface -- removing the outermost layer along the cut lines, exposing cooler, paler inner wood fibres, and producing a linear, directional texture distinct from brushed, smooth, or hand-scraped surfaces.

In AM-19, the saw mark process is what creates the pearl grey colour: the circular saw cuts remove the warm amber outer surface layer and expose the grey-silver inner fibres. This makes the grey colour of AM-19 structural rather than applied -- it is the actual colour of the inner oak fibre, not a stain or pigment. UV lacquer then seals the saw mark surface, fixing the pale grey colour and protecting it with a hard, durable finish.

Q3. How is AM-19 pearl grey different from AM-03 white oak?

AM-19 pearl grey achieves its cool colour through the saw mark surface process that exposes the grey inner fibres of the oak; AM-03 white oak achieves its pale colour through a white oil treatment that adds white pigment to the surface -- the mechanisms are completely different, the visual results are similar in lightness but different in tone.

AM-19 is greyer and cooler -- a silver-grey-white; AM-03 is warmer and creamier -- a white-beige. AM-19 is 260mm wide (extra-wide plank) with UV lacquer; AM-03 is 190mm with natural oil. AM-19 is a lacquered floor requiring no periodic oiling; AM-03 requires re-oiling every 1-3 years with white maintenance oil.

Q4. What does 260mm extra-wide plank mean?

260mm wide plank means each board is 260mm across -- significantly wider than standard 190mm planks and wider than AM-05's 220mm -- producing the maximum available board width in the AMUER long plank range, with the fewest joint lines across any given room width.

In a 3m wide room, 260mm boards produce approximately 11 joint lines versus approximately 15 for 190mm boards. The wider board means the grain pattern, saw mark texture, and grey colour all develop across a larger canvas per board. AM-19 at 260mm is the specification for spaces where the floor should read as close to a continuous surface as an engineered wood floor can achieve.

Q5. Can AM-19 be used over underfloor heating?

Yes -- AM-19 engineered hardwood flooring is compatible with both hydronic and electric underfloor heating systems, with a maximum recommended surface temperature of 27 degrees C.

The 3-layer engineered construction resists dimensional movement under heating cycles. Extra-wide 260mm boards require stricter humidity management than narrower boards -- maintain 45-60% RH year-round. Switch off heating 48 hours before installation and restart gradually after installation, increasing by 1-2 degrees C per day. UV lacquer handles UFH thermal cycling without cracking risk.

Q6. Will the grey colour of AM-19 fade or change over time?

The grey colour of AM-19 is very stable under UV lacquer -- it will not fade in the way that pigment-stained or oil-treated floors can fade, because the pale grey tone of AM-19 comes from the structural colour of the inner oak fibre exposed by the saw mark process, not from an applied pigment or stain.

Under normal use and UV lacquer protection, the AM-19 tone changes very slowly over many years. Unlike natural oil finishes that deepen and warm over time, UV lacquer provides a stable, sealed surface that prevents oxidation and light exposure from significantly altering the pale grey colour. If the floor is eventually sanded and refinished, the saw mark surface can be re-created and the grey tone will be restored.

Q7. Can AM-19 be sanded and refinished?

Yes -- AM-19 has a 4mm solid oak wear layer supporting 3-4 full sanding and refinishing cycles over the floor's lifespan.

After sanding, the saw mark surface can be re-applied and the floor can be re-finished with UV lacquer to restore the pearl grey appearance. Alternatively, after sanding, AM-19 can be finished without the saw mark process and refinished with UV lacquer, natural oil, or white oil -- changing the appearance of the floor to a natural or white-oiled tone. Full refinishing should be carried out by a professional with the appropriate saw mark equipment.

Q8. What is the minimum order for AM-19?

The standard minimum order for AMUER AM-19 is 200 m2 per SKU from our China factory.
