White Oil Herringbone Oak Engineered Flooring EF Grade — Smoked Broken Edge — AC-11

AC-11 is a 90×500mm herringbone engineered oak floor in EF maximum character grade with four compounding surface treatments — brushed grain texture, moderate smoke treatment, broken edge profile, and white oil finish: 14/3mm 3-layer construction with a 3mm solid European oak wear layer, tongue-and-groove (T&G) glue-down or nail-down installation.

AC-11 applies the most complex surface treatment combination in the AMUER herringbone range to the highest natural character grade available. The four treatments each operate differently: the moderate smoke lightly darkens the natural oak tone; the brushed surface opens the grain in tactile relief; the broken edge creates fine shadow lines at every stave joint, articulating the herringbone geometry; and the white oil penetrates the smoked, brushed surface to lift the colour toward a warm pale honey-cream — partially counteracting the smoke's darkening effect to produce a tone that is simultaneously smoked and pale, warm and Nordic, characterful and light.

The EF grade provides the densest natural knot character available — open knots, black knots, swirling grain around the knots, and dramatic figure are all visible at the maximum intensity of the EF grading standard. Combined with the white oil's pale, translucent finish, these knots read as dark caramel-brown to near-black focal points within the warm pale honey field — the maximum natural drama available in a light-coloured herringbone.

Full Product Specification

Specification	AC-11 Detail
Product Code	AC-11
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	14/3mm (14mm total, 3mm wear layer)
Top Layer	3mm solid European oak — supports 1–2 light sanding cycles
Stave Dimensions	90mm wide × 500mm long — slightly shorter stave than AM-23's 600mm; the 500mm length produces a slightly more compact herringbone rhythm at the same 90mm width
Pattern	Herringbone — square-cut staves laid in alternating 90° pairs; broken staggered zigzag joint; the broken edge profile at each stave joint creates a fine shadow line that articulates every joint in the herringbone formation, making the pattern geometry more clearly visible than a square-edge herringbone
Colour	AC-11 Warm Pale Smoked Oak — a warm pale honey-cream, the result of white oil being applied over a moderately smoked oak base; the smoke treatment lightly darkens the natural oak toward a warm amber-tan, then the white oil penetrates to partially lift and brighten this smoked tone toward a paler, more cream-honey register; the final colour sits between natural honey-sand and medium-smoked tan, with a subtle warmth and a Nordic-inflected pale quality that neither untreated natural oak nor more deeply smoked products achieve; the EF grade adds dramatic tonal variation within this pale palette — dense knots read as dark caramel-brown to near-black focal points, swirling grain around knots reads as warm amber, and straight-grain clear areas read as pale cream-honey
Surface Treatment	Smoked + Brushed + Broken Edge + White Oil
Finish	White Oil — a penetrating oil containing fine white pigment particles; unlike clear natural oil, white oil both penetrates the wood fibres and deposits a micro-layer of white pigment in the grain and pores; the effect is a pale, brightening, slightly chalky lift to the wood colour — reducing the yellow and amber undertones of standard natural oil, suppressing the darkening effect of the smoke treatment, and producing a warmer, more Scandinavian-inflected pale tone; white oil requires periodic maintenance re-oiling every 12–18 months, using a compatible white oil maintenance product to maintain the pale, brightened colour effect over time
Grading	EF — Maximum Natural Character Grade: the highest character grade available in the AMUER range; accepts all natural features of European oak at maximum intensity: open knots (some large), filled knots, black knots, swirling grain around knots, pronounced grain movement and figure, checks, splits, significant heartwood-to-sapwood colour variation; every board is maximally individual; in combination with the white oil's pale, translucent finish, EF grade knots read as dramatically dark warm-brown to near-black focal points within the pale honey-cream field — a vivid natural contrast that is the defining visual quality of AC-11
Edge Profile	Broken Edge — lightly hand-distressed stave edges creating subtle shadow lines at every herringbone joint; the broken edge makes the herringbone geometry more visually articulated than a flush square-edge joint, and adds handcrafted character appropriate to the EF grade and white oil aesthetic
Installation	T&G (Tongue-and-Groove) — glue-down (recommended) or nail-down (timber subfloor only); floating not recommended
Underfloor Heating	Compatible — maximum surface temperature 27°C; maintain 45–60% RH year-round; white oil finish requires careful humidity management; use flexible polyurethane adhesive for UFH installations

PRODUCT OVERVIEW · AC-11 WHITE OIL EF HERRINGBONE

The Most Characterful Pale Herringbone — EF Grade, Four Treatments, White Oil

AC-11 is the most complex and characterful pale-toned herringbone in the AMUER range — the product of applying the maximum natural character grade (EF) and four compounding surface treatments (smoked, brushed, broken edge, white oil) to the classic 90mm herringbone format.

The key tension at the heart of AC-11's specification is one that defines its visual identity: the EF grade delivers the most dramatic, the most knot-dense, the most individually characterful oak available in the range — the 'maximum natural drama' end of the grading spectrum. The white oil finish places this maximum character oak in the palest, most Nordic-inflected colour register available — the 'most light and airy' end of the finish spectrum. These two decisions, which might seem contradictory, produce together a floor of unusual visual complexity: a pale, bright, warm honey-cream surface scattered with dark, warm-brown to near-black knots and swirling grain that read as vivid natural focal points against the light background.

This is a deliberately different approach from AM-23's 'cool character' (CD grade, invisible-treated cool greige) and from AC-10's 'warm smoked' (DE grade, moderate smoke, no white lift). AC-11's character is warm and pale simultaneously — warm from the underlying smoke, pale from the white oil, characterful from the EF grade, and handcrafted from the broken edge. It is the herringbone floor for specifications where natural oak character is the design brief, and where that character should read in the warmest, most Nordic, most light-open register rather than in a deeper, darker, more dramatic tone.

Design Guide

AC-11's warm pale honey-cream colour, EF maximum character grade, broken edge detail, white oil finish, and herringbone pattern combine to suit a specific set of interior directions where natural oak drama is desired in a light, airy, Nordic-warm palette:

Japandi & Nordic Character

AC-11's white oil pale tone and EF grade character knots define the Japandi floor aesthetic at its most natural and characterful: light enough to read as airy and spatial, warm enough to feel natural and organic, and materially characterful in a way that AB or CD grade pale floors cannot achieve. The white oil's Nordic inflection and the EF grade's dense knotting are the combination that makes AC-11 the most distinctive pale herringbone in the AMUER range.

Farmhouse & Country Natural

AC-11's EF grade knots and broken edge read as authentically rustic and naturally characterful in farmhouse and country natural interiors. The white oil's pale, warm tone is sympathetic to cream walls, natural stone, terracotta, and warm timber elements, while the herringbone pattern adds geometric sophistication to the natural rustic palette.

Design-Led & Artisan Contemporary

For design-led contemporary interiors that prize authentic natural materials and deliberate imperfection over standardised consistency, AC-11's EF maximum character grade, broken edge, and white oil combination deliver a floor that reads as genuinely artisan and individually characterful — a floor that could not be replicated by a cleaner, more consistent specification.

Installation & Room Suitability

Herringbone T&G Glue-Down Installation

AC-11 uses T&G glue-down (recommended) or nail-down installation.

· Subfloor flatness: 3mm per 2m maximum

· Adhesive: flexible polyurethane or MS polymer; full-spread across stave back

· Establish herringbone spine line from room centre or focal wall at 45° to room walls

· Dry-lay 10–15 staves before committing to adhesive

· Broken edge joints: do not fill or caulk

· Expansion gap: 10mm minimum at all walls

· Acclimatise 48 hours before installation

· Protect finished floor from moisture 72 hours after installation — white oil surface requires full cure before foot traffic

Underfloor Heating

AC-11 is compatible with both hydronic and electric UFH with T&G glue-down installation using flexible polyurethane adhesive.

· Maximum surface temperature: 27°C

· Maintain 45–60% RH year-round — more critical for white oil than UV lacquer

· Switch off heating 48 hours before installation

· Restart at 1–2°C per day maximum

· White oil finish requires consistent humidity to maintain colour and surface integrity under UFH cycles

· Thermal resistance: 0.15 m²K/W maximum

Room Suitability

Room / Application	Suitability	Notes
Japandi & Nordic-Influenced Living Rooms	Exceptional	AC-11's warm pale colour, EF grade natural character, and broken edge are the defining combination for Japandi and Nordic interiors seeking maximum natural oak drama in a light, airy, pale floor. The white oil's warm pale tone complements natural linen, pale oak, rattan, and matte-black fixtures perfectly.
Design-Led Character Interiors	Exceptional	For design-led interiors specifying a pale herringbone floor with genuine maximum natural oak character — not the clean, consistent AB grade of standard herringbone floors — AC-11's EF grade, broken edge, and white oil deliver a floor that reads as authentic, artisan, and materially individual.
Entrance Halls	Excellent	The broken edge articulates the herringbone geometry clearly in entrance hall proportions; the pale colour maximises light in naturally darker entrance halls; the EF grade knots create an immediate visual impression of natural quality.
Master Bedrooms	Excellent	White oil's warm, matte finish and pale colour create a calm, natural bedroom floor. EF grade warmth and character add individuality to the bedroom environment.
Farmhouse & Country Contemporary	Excellent	AC-11's EF grade knots, broken edge, and warm pale tone are naturally rustic and appropriately characterful for farmhouse and country contemporary interiors.
Dining Rooms	Excellent	Warm pale herringbone creates an inviting dining room floor. White oil requires prompt spill response — more maintenance-aware than UV lacquer for a dining context.
Kitchen-Diners	Very Good	White oil is more susceptible to water and spill damage than UV lacquer — prompt and thorough spill wiping is essential in kitchen environments. Consider UV lacquer alternatives for high-traffic kitchen areas.
Bathrooms	Not Recommended	Not suitable for persistent moisture exposure.

Care & Maintenance — White Oil EF Herringbone

Task	Method
Daily	Dry sweep or vacuum with soft brush head, sweeping along the herringbone stave direction. The pale white-oiled surface shows dark grit, soil, and pet hair clearly. The EF grade open knots and broken edge joints also collect fine debris — sweep thoroughly and regularly.
Weekly	Damp mop with well-wrung cloth and a compatible white oil floor cleaner — not UV lacquer cleaners, not standard household cleaners. White oil is a surface-open penetrating finish, more moisture-sensitive than UV lacquer. No steam mop, no standing water.
Spills	Wipe immediately with a dry cloth. The white oil surface provides limited, short-term moisture resistance; prompt, thorough spill wiping is essential. The EF grade open knots and broken edge joints require particular attention as moisture can penetrate more readily at these points.
Open knots (EF grade)	Vacuum with soft brush attachment periodically to remove debris from open knots in the EF grade surface. Do not force water or cleaning products into open knots. If desired, open knots can be filled with a manufacturer-matched white-oil-compatible wood filler.
Broken edge joints	Vacuum along joint lines with soft brush attachment. Do not fill or caulk the broken edge — it is a design feature. Do not force water or cleaning products into the broken edge joint.
Periodic re-oiling	Re-oil with compatible white oil maintenance product every 12–18 months. It is critical to use a white oil maintenance product — not a clear natural oil or wax oil — to maintain the pale, brightened colour effect. Using clear natural oil over white oil will progressively darken the floor toward a standard natural-oiled tone, losing the white oil effect over time.
Scratches	Light surface scratches: spot re-oiling with white oil maintenance product after light sanding. Deeper damage: professional sanding and white oil recoating.
Never	team mop · standing water · clear natural oil maintenance products over white oil (changes colour) · standard household cleaners · bleach or acid cleaners · UV lacquer maintenance products · silicone-based polishes · abrasive pads.

FAQ

Q1. What is white oil herringbone engineered oak flooring?

AC-11 is a 90×500mm herringbone engineered oak floor with four surface treatments (moderate smoke, brushed grain, broken edge, white oil finish) in EF maximum character grade, 14/3mm 3-layer construction, T&G installation. White oil is a penetrating oil finish containing fine white pigment particles that partially brightens and lifts the smoked oak colour toward a warm pale honey-cream — producing a Nordic-inflected, warm-pale tone distinct from both natural clear-oiled oak and UV lacquer finishes.

Q2. What is the difference between white oil and natural oil on oak flooring?

Natural oil is a clear penetrating oil that soaks into the wood fibres to enhance colour depth and provide surface protection — it typically adds warmth and amber tones. White oil is a variant containing fine white pigment particles; it penetrates the wood similarly but the white pigment partially brightens and desaturates the natural wood colour, reducing yellow/amber undertones and producing a paler, more Nordic-inflected tone. Both require periodic re-oiling maintenance (every 12–18 months), but the maintenance product for white oil must also be a white oil product — using clear natural oil over white oil will progressively darken the floor, losing the pale white oil effect.

Q3. Why use EF grade for a pale-coloured herringbone floor?

EF grade is the maximum character grade — the most knot-dense, figure-rich, and individually characterful grading in the AMUER range. On a pale white-oiled surface, EF grade knots read with maximum visual contrast: the dense knot material resists the white oil's lightening effect, so EF knots appear as vivid dark caramel-brown to near-black focal points against the pale honey-cream field. This dramatic pale-background / dark-knot contrast is AC-11's defining visual quality — a maximum-character floor that is simultaneously pale and dramatic, light and richly characterful.

Q4. How do I maintain white oil herringbone flooring to keep the pale colour?

The key maintenance rule for AC-11 white oil is to use a compatible white oil maintenance product — not clear natural oil — when re-oiling every 12–18 months. Using clear natural oil over white oil will progressively darken the floor toward a standard natural-oiled tone, losing the characteristic pale, Nordic-inflected colour that white oil provides. For daily maintenance: dry sweep regularly (pale colour shows dust readily), damp mop weekly with pH-neutral white oil floor cleaner, and wipe spills immediately. Never use UV lacquer maintenance products on white oil flooring.

Q5. Can AC-11 be installed over underfloor heating?

Yes — AC-11 is compatible with both hydronic and electric underfloor heating with T&G glue-down installation using flexible polyurethane adhesive. White oil finish requires consistent indoor humidity management (45–60% RH year-round) — more critical than UV lacquer products. Maximum surface temperature 27°C. Switch off heating 48 hours before installation; restart gradually at 1–2°C per day.

Q6. How is AC-11 different from AM-23?

AC-11 and AM-23 are both 90mm herringbone floors with T&G installation and brushed + broken edge surface treatments, but differ significantly. AC-11: EF maximum character grade, moderate smoke + white oil finish (warm pale honey-cream colour), 90×500mm stave, periodic re-oiling required. AM-23: CD natural character grade, invisible treatment + UV lacquer finish (cool greige colour), 90×600mm stave, no re-oiling required. Specify AC-11 for maximum natural knot character in a warm pale Nordic tone with a traditional oil finish. Specify AM-23 for natural character in a cool greige contemporary tone with practical UV lacquer.
