Detail Information
AMUER · OAK 3-LAYER · SERBIA WAREHOUSE
Natural Oil Finished 220mm Wide Plank European Oak Flooring (S Grade – Serbia Stock) — SA-03
SA-03 is a 220mm wide plank European Oak engineered floor graded as S grade – a rustic character grade that sits below EF in AMUER’s grading hierarchy. It features a 14/3mm three‑layer construction with a 3mm solid European oak wear layer, a brushed surface texture, a penetrating natural oil finish, and a Uniclic‑compatible click floating system. SA-03 is held in AMUER’s Serbia warehouse, enabling immediate dispatch to EU buyers without factory lead times, container freight delays, or customs holds.
Unlike the cleaner, more uniform EF grade, S grade is deliberately specified to allow a broad range of natural wood characteristics that give the floor its distinctive rustic personality. Every board carries visible evidence of the tree’s natural growth: knots of all types (fresh, cracked‑filled, and dead), fine surface cracks, colour shifts from board to board, subtle structural grain variation, and other organic marks. These are not defects in the context of this grade – they are the defining aesthetic features that make SA-03 a warm, authentic, and visually engaging floor.
The 220mm width amplifies the impact of these natural features. Where a narrower board might compress the visual field, the wide face gives each knot, grain swirl, and colour transition room to breathe and be appreciated. The brushed surface opens the grain to receive the natural oil, which in turn enriches the honey‑gold tones and gives the entire floor a deep, warm, matte glow. The result is a floor that feels lived‑in, natural, and generously scaled – ideal for interiors that celebrate material authenticity and rustic warmth without sacrificing modern engineered performance.

| 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 2‑3 light sanding and refinishing cycles | |
Board Width | 220mm — a contemporary wide plank format that provides a generous surface for the rustic S‑grade features to be fully appreciated | |
Board Length | 2,200mm — creates a strong directional rhythm with a 10:1 length‑to‑width ratio | |
Colour | SA-03 S Grade — warm honey‑gold with permitted colour variation across boards (from light golden to medium amber). The natural oil deepens and enriches this base tone, giving the floor a warm, inviting glow that complements the rustic character. | |
Surface Treatment | Brushed — the wire‑brush process opens the early‑wood fibres, creating a fine relief texture. On S‑grade oak, brushing enhances the visibility of knots, grain lines, and other natural features while ensuring the natural oil penetrates evenly across the wide 220mm face. | |
Finish | Natural Oil — plant‑based penetrating oil that feeds the wood fibres, enriches the warm honey‑gold colour, and leaves an open‑pore, matte, tactile surface. The oil accentuates the rustic character of S grade by bringing depth to knots and grain. Periodic maintenance re‑oiling is required every 1‑3 years. | |
Grading | S Grade (Rustic Character – Lower than EF)** embraces the full natural character of European oak, allowing unlimited sound, filled cracked, and dead knots (provided structural integrity is maintained), together with natural dark lines, colour and structural variation, filled bark pockets, colour-matched sapwood, slight filled worm holes, blue stain, slight rot, and natural discolouration. Cracks of up to **15mm × 1000mm** are permitted. Rather than minimizing these features, S Grade highlights the authentic growth characteristics of the timber, giving SA-03 a warm, rustic appearance with rich visual variation and a distinctive handcrafted character that differs from the more uniform appearance of higher-grade flooring. | |
Edge Profile | Micro-Bevel — precision machined chamfer on all four board edges; creates a uniform V-groove shadow line between boards; on EF grade at 150mm the micro-bevel defines each board without competing with the dramatic natural features | |
Installation | Click floating (Uniclic-compatible) — no adhesive required | |
Underfloor Heating | Compatible — maximum surface temperature 27°C; maintain 45–60% RH year-round; natural oil finish requires careful humidity management over UFH | |
Emission Class | E1 | |

PRODUCT OVERVIEW · SA-03
Embracing Authenticity – The Rustic Appeal of S Grade
SA-03 makes its statement through the confident display of natural wood character. The 220mm wide plank provides an expansive canvas, and the S grade specification ensures that this canvas is filled with the authentic marks of European oak’s natural growth – knots, grain deviations, subtle colour shifts, and the occasional fine crack or bark pocket. Where higher grades such as EF aim for visual uniformity, S grade celebrates the tree’s individuality.
This design approach is particularly effective at 220mm width. A wide board gives each natural feature space to become an integral part of the floor’s visual rhythm. A knot is not hidden or filled to disappear – it becomes a focal point that adds texture and story to the plank. A colour variation from one board to the next creates a gentle, organic flow across the room rather than a flat, repetitive grid. The result is a floor that feels grounded, warm, and deeply connected to its material origins.
The natural oil finish is the essential partner to this rustic S grade surface. Where a lacquer would seal the wood under a plastic‑like film, natural oil penetrates and enriches. It brings out the warm honey‑gold of the oak, deepens the contrast around knots and grain lines, and leaves a matte, open‑pore finish that is a pleasure to walk on barefoot. The oil also makes the brushed texture more tactile, adding another layer of sensory richness to the wide boards.
SA-03 is the specification for projects that reject the sterile in favour of the authentic – rustic country homes, contemporary barn conversions, design‑led hospitality spaces, and any interior where the honest expression of natural materials is the guiding principle. With Serbia stock ensuring rapid availability, SA-03 delivers immediate character without the usual factory wait.
Design Guide
SA-03’s S grade rustic character, 220mm width, natural oil warmth, and immediate Serbia availability make it a natural choice for interiors that embrace authenticity, texture, and warmth.
Rustic Country & Farmhouse
SA-03’s knots, cracks, and colour variation are at home in rustic country and farmhouse interiors. The wide planks add a contemporary scale, while the natural oil finish keeps the look authentic, warm, and welcoming.
Modern Barn & Contemporary‑Rustic
The combination of wide‑plank scale and S grade rustic features creates a perfect modern barn aesthetic – clean architectural lines grounded by warm, characterful wood. Pairs beautifully with industrial elements like steel and concrete.
Organic & Natural Eclectic
SA-03 provides a textured, organic foundation for interiors that value natural materials and earthy, layered palettes. The S grade features add depth and interest that evolves with changing light.
Installation & Room Suitability
Click Installation (Floating)
SA-03 uses a Uniclic‑compatible click floating system. No adhesive is required; the boards lock together and float over an approved acoustic underlay on the subfloor. For a 220mm wide plank, floating installation is the preferred method as it allows for natural seasonal movement.
No adhesive – click‑lock floating system
Subfloor flatness: 3mm per 2m maximum
Underlay: acoustic/thermal, maximum 3mm thickness
Expansion gap: minimum 12mm at all walls – essential for 220mm width
Acclimatisation: 48 hours in the installation environment – non‑negotiable for natural oil wide boards
Install parallel to the longest wall
Stagger end joints: minimum 300mm between adjacent rows
Micro‑bevel joints: do not fill or caulk – they are a design feature
Wide‑plank note: wider boards have greater seasonal movement potential; maintain humidity and never reduce the expansion gap
Underfloor Heating
SA-03 is compatible with hydronic and electric underfloor heating systems. The wide 220mm boards require attentive humidity management to ensure stable performance.
Maximum surface temperature: 27°C
Switch off UFH for 48 hours before installation
After installation, increase temperature gradually: +1‑2°C per day to target
Maintain indoor humidity at 45‑60% RH year‑round – critical for 220mm boards
Natural oil finish: humidity control prevents surface drying and checking
Thermal resistance: 0.15 m²K/W maximum
Room Suitability
| Room / Application | Suitability | Notes | |
| Rustic & Farmhouse Living Rooms | Exceptional | SA-03’s S grade character is perfectly suited to rustic and farmhouse interiors. The knots, cracks, and colour variation create the authentic, welcoming atmosphere that defines these styles. | |
| Modern Barn & Contemporary‑Rustic | Exceptional | The 220mm width keeps the floor contemporary and architectural, while the S grade features provide the rustic warmth essential to the modern barn aesthetic. | |
Country Kitchens (dry zones) | Very Good | The natural oil finish requires prompt spill response, but the S grade character adds warmth to the heart of the home. Suitable for dining and seating areas. | |
Living Rooms & Open Plan | Exceptional | The wide boards and rustic features create a grounded, relaxed atmosphere. The floor becomes a warm, textural foundation for the entire living space. | |
Bedrooms | Excellent | Warm, natural, and comfortable. The S grade features add cosy, organic texture that makes bedrooms feel intimate and restful. | |
Show Homes & Residential Developments | Excellent | The strong rustic character photographs well and appeals to buyers looking for an authentic, natural floor with immediate availability from Serbia stock. | |
Hotel & Hospitality Fit‑Out | Excellent | Rustic S grade creates a relaxed, welcoming atmosphere in hotels and hospitality settings. Factor in periodic re‑oiling for commercial maintenance schedules. | |
Hallways & Entrance Halls | Good with care | High‑traffic hallways require regular cleaning and periodic re‑oiling. The wide 220mm boards make a bold first impression. | |
Dining Rooms | Very Good | Natural oil needs prompt spill response. The warm character of S grade works beautifully under warm artificial lighting. | |
Offices & Workspaces | Good with care | Natural oil requires more frequent re‑oiling in busy office environments. Desk chair mats are recommended to protect the surface. | |
Bathrooms | Not Recommended | Not suitable for wet environments. | |
Care & Maintenance — Natural Oil on Brushed S Grade 220mm Wide Plank
| Task | Method | ||
| Daily | Sweep or vacuum with a soft brush attachment. The brushed grain and open natural features (knots, small cracks) can collect dust; regular dry cleaning is essential to prevent abrasive wear. | ||
| Weekly | Damp mop using a well‑wrung cloth and a pH‑neutral cleaner formulated for natural oil floors. Never use steam mops, standard household cleaners, or leave standing water on the surface. | ||
Spills | Wipe up immediately with a dry cloth. Natural oil is less water‑resistant than lacquer; do not allow liquids to pool on the wide board surface or run into micro‑bevel joints. | ||
Micro-bevel joints | Never fill or caulk the micro‑bevel grooves – they are an intentional design element. Clean gently with a soft brush along the joint direction. | ||
Periodic re-oiling | Re‑oil every 1‑3 years depending on foot traffic. Use a natural or warm‑neutral maintenance oil that preserves the honey‑gold colour. Apply along the board length, ensure even coverage across the full 220mm width, allow 15‑20 minutes for penetration, then buff off excess. | ||
Humidity management | Maintain 45‑60% RH year‑round. 220mm wide boards are more sensitive to humidity changes than narrower formats. Use a humidifier in dry winters and ensure ventilation in humid summers. | ||
Furniture | Fit felt pads under all furniture legs. Use a protective mat under desk chairs. Always lift (never drag) heavy furniture across the floor. | ||
Never | Steam mop · standing water · ammonia or bleach‑based cleaners · lacquer or polyurethane over the oil finish · abrasive pads · strongly tinted oils (will alter the warm honey‑gold colour) · filling micro‑bevel joints. | ||

FAQ
Q1. What is SA-01 and why is it stocked in Serbia?
SA-01 is a 150mm long plank EF maximum natural character grade engineered oak floor, light brushed and finished with natural oil, with click floating installation. It is stocked in AMUER’s Serbia warehouse rather than shipped from the China factory because Serbia’s central European location allows significantly faster dispatch to EU markets than China origin stock. For EU buyers with urgent project timelines, SA-01 from Serbia stock avoids the 15–25 day factory lead time and container shipping time from China, providing the fastest available engineered oak specification in the AMUER range for European buyers.
Q2. What is the difference between light brushed and standard brushed?
Light brushed (SA-01) applies a gentle wire-brush treatment that opens the grain texture subtly without the more pronounced ridged relief of a standard brush treatment. On EF grade with large knots and complex natural features, the light brush is deliberately restrained: it adds just enough grain texture to ensure even natural oil penetration and provide a subtle tactile quality, without adding a heavy additional texture layer over the already dramatically featured EF grade surface. Standard brushed treatments are more aggressive, creating a more pronounced ridge-and-channel texture that reads more strongly across the board face.
Q3. Why does SA-01 use natural oil rather than UV lacquer?
Natural oil is the most authentic finish for EF maximum character grade rustic oak. It penetrates the light-brushed fibres and becomes part of the wood surface, deepening and enriching the warm honey-gold EF grade colour and producing an open-pore matte surface that is tactile and warm in a way UV lacquer cannot replicate. For clients who want the most natural, warm, and authentic presentation of EF grade oak, natural oil is the correct choice. For clients who prefer low-maintenance without periodic re-oiling, the NC-02 (same EF grade, UV lacquer, 190mm, China factory order) would be more appropriate.
Q4. What maintenance does natural oil on EF grade require?
Natural oil requires periodic re-oiling every 1–3 years depending on traffic, using a natural or neutral warm-toned oil maintenance product. Daily sweeping to remove grit from the light-brushed grain channels. Weekly damp mopping with pH-neutral natural oil floor cleaner only. Immediate spill response — natural oil is less water-resistant than UV lacquer. Never apply standard household cleaners, lacquer products, or strongly tinted maintenance oils to SA-01.
Q5. Can SA-01 be used over underfloor heating?
Yes — SA-01 is compatible with both hydronic and electric UFH, maximum surface temperature 27°C. Maintain indoor humidity at 45–60% RH year-round — this is particularly important for natural oil over UFH, as the combination of heating and low humidity can cause oil-finished floors to dry and crack more readily than lacquered floors. Click floating installation accommodates thermal expansion without adhesive constraint.
Q6. Are the knots and cracks in EF grade SA-01 structurally stable?
Yes — all open features in SA-01 are factory-filled with colour-matched filler and are fully structurally stable before the natural oil is applied. During re-oiling maintenance, oil can be applied across the full board face including filled features without risk of loosening or damaging the fills. All factory-filled features in SA-01 are stable under normal residential use, cleaning, and periodic re-oiling.
Q7. How do I check current Serbia stock availability?
