Oak skirting wholesale: how to match skirting batches to parquet batches by floor and room without color variation

The project has 180 apartments and eight floors. Oak parquet was purchased in three phases. According to the invoices, the same material and the same decor are listed everywhere. The skirting board was decided to be ordered later, after the floor was installed. On paper, the task looks simple: choose an oak profile and order the required linear meters. On site, it turns out that the floor on floors 2–3 is slightly warmer, on floors 4–5 it is calmer and grayer, and in another building the same item looks slightly deeper under artificial lighting.

This is a normal risk for a large project with natural wood and multiple deliveries. The solution is not to look for a “perfectly identical oak plank” for every board, but to link the future skirting board purchase to the actual floor map.

Working sequence: actual floor batch → object zone → physical reference → selected oak PLT profile → skirting finish code → control sample → clean square footage → separate cutting plan → skirting batch → marking → reserve → reorder using the same reference.

Key principle: the skirting is matched not to the words “natural oak” on the invoice, but to the actual floor finish of the specific zone.

The same label “natural oak” does not yet mean the same floor throughout the entire project

On a large project, the same commercial name of flooring can span several deliveries, different production dates, different wood batches, and different stages of finish application. Even if the product is formally the same, natural wood retains variability.

On the finished floor, differences may appear:

• in saturation;
• in the warmth or coolness of the undertone;
• in the contrast of the texture;
• in the reaction of the oil or lacquer to light;
• in the degree of gloss;
• in the pattern of individual planks;
• in the overall visual impression of a large area.

You cannot draw a conclusion from a single board. An individual parquet plank may be lighter or darker than its neighbors for natural reasons. For the skirting board, what matters is not the photographic identity of each lamella, but the overall visual range of the zone.

If floors 2–3 generally read as warmer than floors 4–5, one universal tint for the skirting board may look convincing in the first zone and noticeably weaker in the second.

Why the new article does not repeat the usual advice “oak to oak”

STAVROS already separately analyzes wooden skirting board for parquet and the principle of matching the species. Here this thesis is taken as the starting point. Next, another task is addressed: how to manage several real batches of flooring on a large project.

Watch video ...

One should strive for the visual integrity of the zone, not for the printed identity of each plank

Oak is a natural material. It has its own texture, radial and tangential sections, calmer and more active fragments. If you demand that the skirting board be absolutely identical to every parquet board, the task becomes physically meaningless.

The right goal:

PREVENT A SYSTEMIC VISUAL DISCONNECT BETWEEN THE FLOOR OF THE ENTIRE ZONE AND THE SKIRTING BOARD THAT FRAMES IT.

That is, natural variation in the pattern is acceptable, but there should never be a situation where the entire floor looks honey-warm while the skirting board around it remains consistently gray-cool.

What can actually be controlled

• overall tone;
• undertone;
• type of coating;
• gloss level;
• depth of tinting;
• acceptable character of the texture;
• distribution of overly contrasting planks along long sightlines.

It is not "every single grain" that is controlled, but the visual system.

A floor batch map is required before ordering skirting boards

Insufficient source information:

“Oak parquet — 6000 m²”.

Strong:

The floor batch number matters not because the skirting board must be made from the same wood batch. It is needed as a reference to the actual color zone of the property.

Why the installation map is more important than a single delivery note

The delivery note shows what arrived and when. It does not always show where it was actually installed.

On site, the following is possible:

• redistribution between floors;
• using the remainder of the first delivery on the next floor;
• replacing damaged packaging;
• partial top-up from the next batch;
• moving material between buildings.

Therefore, the floor purchasing documentation and the actual installation map are two different data sources.

The actual installed floor is often more convenient than a warehouse sample

If the parquet has already been installed and finished, this is a strong reference. It shows the final appearance, not an intermediate board before installation.

On the finished area, you can evaluate:

• the overall tone after oil or lacquer;
• gloss;
• the texture over a large area;
• behavior under daylight;
• behavior under artificial lighting;
• real contrast with the wall.

For the skirting board, it is especially useful to look at the lower part of the room next to the wall, because that is exactly where the profile will run.

When a separate board is still needed

A physical portable sample is convenient for approval with the manufacturer. Therefore, it is optimal to have:

• a control area on site;
• a signed board or sample;
• a photo as supporting material.

A photograph helps to remember the context, but does not replace the physical reference.

A floor reference sample must be labeled as strictly as a SKU

The phrase “oak sample from the third floor” quickly stops being unambiguous. Two months later, no one remembers which apartment it was taken from or which delivery it belongs to.

Working marking:

FLOOR‑P01 / BUILDING A / FLOORS 2–3 / DATE / STATUS APPROVED.

If there is a separate physical sample:

SAMPLE FLOOR‑01 → FLOOR‑P01.

What to store next to the reference sample

• batch or delivery number;
• object;
• installation area;
• date;
• coating description;
• linked skirting finish code;
• approval version.

This data allows reproducing the decision a year later better than the verbal “that oak was a bit warmer.”

For the skirting board, a corresponding map is created: “floor → finish → zone”

After the floor map, a second table appears.

One profile. One material. But procurement results in three variants if three real floor groups require different finishes.

This is exactly how wholesale oak skirting stops being a single depersonalized batch “in oak.”

Why the finish code D‑01 matters more than the words “natural oak”

A color name may repeat across different suppliers and catalogs. Code D‑01 links:

• physical sample;
• test patch;
• zone;
• order;
• packaging;
• additional order.

This is the project’s internal language.

One SKU can turn into several purchasing variants

On a large project, it is convenient to keep one skirting geometry. For example, oak PLT‑001‑1 is used in all apartments. This reduces the number of SKUs and simplifies reserves and repeat orders.

But if the floor actually splits into three visual groups, one SKU turns into three purchasing lines:

• PLT‑001‑1 / oak / D‑01;
• PLT‑001‑1 / oak / D‑02;
• PLT‑001‑1 / oak / D‑03.

One geometry. One material. Finish and zone assignment differ.

Why this is still unification

Unification does not mean one color. It means the project preserves:

• one profile;
• one height;
• identical door joints;
• identical installation logic;
• identical commercial length of the oak version;
• different but manageable finishes.

This is stronger than three different PLT profiles for three floor groups.

When you can keep one finish for the entire project

You should split the oak skirting into D‑01, D‑02, and D‑03 only when the actual floor truly forms distinct visual groups.

if:

• FLOOR‑F01, FLOOR‑F02, and FLOOR‑F03 are close in tone;
• the difference does not form a noticeable block at floor level;
• the overall skirting finish works convincingly alongside all zones;
• control samples confirm compatibility;

it is better to keep one D‑01 for the entire project.

There is no need to artificially multiply finishes just because parquet deliveries had different numbers.

The decision is made by comparison, not by batch number

The batch number is a signal to check. It is not an automatic basis for a separate color.

Two different deliveries may visually match well enough. Conversely, part of one formally common delivery, after installation under different conditions, may be perceived differently.

When the floor batches need to be divided into separate baseboard groups

A separate finish is justified if the difference already reads as a systematic color block.

For example:

• floors 2–3 are noticeably warmer;
• floors 4–5 have a cooler grayish undertone;
• building B uses a different oil or a deeper tint;
• the common area is finished with a separate finish.

Then a single universal baseboard may look convincing only in one part of the property.

Why you shouldn't mix two groups just to simplify the warehouse

The warehouse does indeed become simpler with a single finish. But if the price of that simplicity is a noticeable boundary of "one floor, a different skirting board," the project loses.

Supply optimization should work within the architecturally acceptable range.

There is no need to invent a universal ΔE threshold without a project requirement

Instrumental color control is useful when it is provided for by the project documentation, the finishing system, or the contract. But the article should not invent a universal numerical value after which oak is automatically considered "different."

If the project has not set an instrumental standard, the real working system is built on:

• physical samples;
• visual range;
• control color swatches;
• on-site comparison;
• fixed finish.

The main mistake is to create a pseudo-technical rule that does not exist with the manufacturer or in the project documentation.

When instrumental control is still needed

If the customer has themselves established a measurable color and gloss standard, it must be included in the specification and the contract. Then control becomes part of the official process, not a recommendation in an article.

A control sample is made separately for each problem group of the floor

If FLOOR‑P01 and FLOOR‑P02 differ visually, one common sample of the oak skirting does not solve both tasks.

The following are created:

D‑01 → FLOOR‑P01.

D‑02 → FLOOR‑P02.

For FLOOR‑P03 — D‑03, if the third group is indeed separate.

What a control test patch should show

• overall tone;
• undertone;
• the wood's reaction to the chosen finish;
• gloss level;
• the character of the grain after coating;
• compatibility with the finished floor.

It is best to apply the finishing system to the same material and preparation that will be used in the series.

Why you cannot store just a can of stain

The name and composition of the coating alone do not guarantee reproducibility of the result. The outcome is influenced by:

• wood preparation;
• grinding;
• number of layers;
• application method;
• holding time;
• Final Coating

Therefore, a physical sample of the finished skirting board is stored together with the technology.

The sample should be viewed on site under real lighting

The same oak shade can be perceived differently:

• by a large window;
• deep in a hallway;
• under warm evening light;
• under cool general lighting;
• next to a dark or light wall.

This does not mean that every light fixture needs a new skirting board color.

First, you need to determine: is the material actually different, or is the effect created by the light?

Why a long hallway is especially revealing

In a small room, the skirting board is perceived in short sections. In a hallway, the same line stretches for tens of meters. Any systematic difference between the floor and the skirting board is more noticeable here.

Therefore, for D-02, which is intended for a corridor, it is better to evaluate the control sample specifically in the corridor lighting environment.

Oak species does not guarantee the same color

An oak skirting board and oak parquet are naturally matched by material, but the word "oak" does not determine the final shade.

The difference may occur due to:

• natural wood;
• radial and tangential grain pattern;
• sanding;
• stain;
• colored oil;
• clear oil;
• lacquer;
• number of coats;
• saturation levels;
• matte or gloss finish.

Therefore oak baseboard is selected as the material, while the finish is coordinated separately with the actual floor.

Why the same pigment does not guarantee the same result

Parquet and skirting boards may have different surface preparation. Even with a similar coating, oak can "take" the tone differently. The final decision is confirmed by a sample, not just the name of the composition.

Gloss and depth of finish affect the perception of tone

Matte and more glossy oak reflect light differently. Therefore, two samples with a similar pigment may be perceived as different in saturation.

Not only the color is coordinated.

Need to check:

• coating type;
• matte finish;
• visual depth;
• texture contrast;
• behavior under side lighting.

Why this is especially noticeable in a long line

A glossier baseboard under side lighting may appear darker or more contrasting than the floor. At one point it is almost imperceptible, but along a twenty-meter corridor the effect becomes systemic.

A brushed floor does not require mechanically brushing the baseboard

If the engineered board has a pronounced texture, the baseboard does not have to literally replicate every mechanical treatment.

There are several acceptable strategies:

• a calmer baseboard, but in the same tone;
• a baseboard with a similar texture;
• a slightly darker baseboard as a frame;
• a contrasting option, if it is part of the design.

The choice is confirmed by the physical node “floor + skirting board”.

Why you shouldn't copy the texture without checking

Heavy brushing on a narrow profile can look coarser than on a large floor surface. What looks beautiful on a 180 mm wide board does not have to work the same way on a 100–120 mm high skirting board.

Sorting oak skirting boards is needed for smooth distribution, not for finding the “perfect” planks

Natural oak always has calmer and more active grain elements. On a wholesale project, the task is not to declare one group good and the other bad.

It is necessary to avoid a random sharp contrast within one visible area.

This is especially noticeable:

• in long corridors;
• in halls;
• on walls without furniture;
• under side daylight;
• in rooms with a transparent or semi-transparent finish.

How to distribute without artificial “color grading”

Before installation, you can review several adjacent planks and arrange them so that the pattern transitions are smooth.

This is not a separate product grade. It is the organization of a specific accepted batch.

If one plank is very contrasting, it is not necessarily defective. Perhaps it is better to use it in a short separate area, and not in the middle of a twenty-meter corridor.

A long corridor should be assembled as a separate color zone

If the corridor on a floor is laid with a single batch of parquet, this is a convenient logistical unit.

For it, you can create:

KOR‑02 / POL‑P01 / PL‑D01.

Within such a zone, the following are preserved:

• one skirting finish;
• one reference sample;
• a clear reserve;
• the sequence of planks if needed;
• its own cutting map.

Why it is useful to store the corridor reserve as whole planks

Repairing a long straight wall often requires a whole plank of sufficient length. Many short offcuts with the same total linear meters do not solve the task.

Therefore, the D-01 reserve is assessed not only in meters but also in whole usable lengths.

It is convenient to equip the apartment with a separate oak set

If the entire apartment uses the same flooring batch, an internal set can be created:

KV-01 / FLOOR-P01 / PL-D01.

It includes the required oak skirting for the rooms, hallway, and other areas where this system is used.

This way, the warehouse issues not “32 meters of oak skirting,” but a set for a specific apartment.

Why this is convenient for 180 apartments

If a Type A apartment repeats 60 times, its net footage and cutting layout are calculated once. The set is then replicated with adjustments for actual exceptions.

This reduces:

• manual recalculation;
• the risk of delivering D-02 to apartment D-01;
• loss of reserve;
• random exchange of material between floors.

Multiple floor coverings within an apartment do not automatically mean multiple skirting boards

An apartment may have:

• living room — oak parquet;
• bedroom — engineered board in a different shade;
• hallway — porcelain stoneware;
• bathroom — separate finish.

This does not mean that each zone automatically needs its own oak skirting board.

The architecture may choose:

• one oak profile for all dry rooms;
• two finishes of one profile;
• contrasting skirting board in the hallway;
• a different material in certain zones.

But the floor map needs to be seen before calculation, because it is what shows the potential places where the finish changes.

What to count separately

If D-01 and D-02 really differ, each finish has its own:

• net linear meters;
• Cutting;
• packaging;
• marking;
• reserve;
• additional order.

It is better to tie the transition between two batches of flooring to an architectural boundary

On a project finished in stages, a situation is possible: two adjacent rooms have similar but visually different batches of parquet.

If D-01 and D-02 are approved for them, the skirting board change should not be made in the middle of a continuous wall.

Natural boundaries:

• door casing;
• portal;
• angle;
• change of finish material;
• another clear architectural line.

Why the door is especially convenient

It visually separates the rooms. Even if D‑01 and D‑02 differ slightly, the transition reads as belonging to different rooms, not as an error within a single wall.

What needs to be calculated

The boundary affects the square footage of both finishes. If part of the opening thickness belongs to D‑01 and part to D‑02, the solution must be the same on all standard doors.

It is convenient to use a floor as a color zone only after checking the actual installation

If the entire floor is laid with a single batch of parquet, the scheme is very convenient:

FLOOR 2 → FLOOR‑P01 → FL‑D01.

But one cannot assume this only because the delivery was planned "to the second floor."

They actually could:

• report the remaining stock of POL‑P00;
• move several packages of POL‑P01 to the third;
• use POL‑P02 in one apartment after a defect;
• mix batches in the transition zone.

Therefore, the floor is a convenient logistics unit, but only after actual verification.

The flooring batch log links parquet and skirting throughout the entire project term

It is useful to keep a single log:

The log is needed not only by the procurement team. It is useful for operations if, a year later, a skirting board needs to be replaced in a specific area.

Why a single delivery note is not enough

Because it does not record the actual movement of material within the site. The log is updated as the actual installation progresses.

If the floor map is lost, you cannot install the entire batch of skirting boards blindly

Sometimes skirting boards are purchased late, and there is no longer an accurate map of the parquet batches. This is unpleasant, but it is not a reason to order a single color for the entire oak floor.

A physical survey of typical areas needs to be carried out.

Not every board, but:

• floors;
• buildings;
• standard apartments;
• corridors;
• public areas;
• transition areas.

Survey result

You can get:

Group A — warm natural oak.

Group B — cooler oak.

Group C — separate tinting.

These are project working groups, not official commercial timber grades.

How to move from groups to purchasing

For each group, the following are assigned:

• skirting board item code;
• material oak;
• finishing;
• reference;
• zones;
• linear footage;
• Cutting;
• reserve.

The master specification must link PLT, finish, floor reference, and zone

The word “oak” is mandatory, but not sufficient. It defines the material, but not the specific finish and reference standard.

Why the PLT article number is also insufficient

PLT‑001‑1 is produced in different materials. The current product page shows the oak version 120 × 15 × 2400 mm and MDF 120 × 16 × 2600 mm. The oak item requires the oak line specifically.

If the buyer writes only “PLT‑001‑1”, the supplier still does not know which material configuration to use.

Net meterage must be calculated separately for each finish

Suppose:

• D‑01 — 820 m;
• D‑02 — 640 m;
• D‑03 — 190 m.

Total net footage:

820 + 640 + 190 = 1650 m.

But for procurement this is not one batch of 1650 m.

These are three separate finishing batches.

Why can't cutting be combined to reduce waste

The remainder of D-01 must not automatically go into D-03. Even if the geometry and material are identical, the color identity is different.

Therefore, a separate cutting map is built for each finish.

Why separation increases waste

A single batch has more length combinations. After separation there are fewer parts, so some of the remainders become less useful.

This is a normal effect of architectural separation, not a calculation error.

The reserve is calculated only after separation by finishes and cutting

Correct order:

ZONE → FINISH → FINISHED PARTS → CUTTING → WHOLE STRIPS → RESERVE.

It is incorrect to first add 10% to the total 1650 m, and then divide it between D-01, D-02, and D-03.

A small group D-03 may have a completely different percentage of usable remainder than a large D-01.

What to consider in the reserve

• scale of the area;
• long straight walls;
• likelihood of local repair;
• ability to reorder;
• availability of the same finish a year later;
• the need to preserve a physical reference sample of the batch.

For oak, it is especially useful to keep a few whole planks of the same finish, not just short offcuts.

It is better to start the first batch in an area where the floor is already fully ready

If the project is large, you don't have to order the entire oak skirting board in thousands of meters all at once.

A strong scenario is to start with an area where:

• the floor is already laid;
• the parquet finishing is complete;
• the reference sample is signed off;
• the D‑01 finish is approved;
• the clean square footage is verified;
• the cutting map is ready.

For example, floors 2–3 of building A fully belong to FLOOR‑P01. Here you can produce the first full batch of PLT‑001‑1 / oak / D‑01 and test the system on a real project.

What to check after the first few planks

• tone next to the floor;
• undertone;
• gloss;
• texture contrast;
• behavior under daylight;
• behavior in the evening;
• plank joints;
• combination with casings and doors.

If everything works, the batch is scaled up.

Why a control area is stronger than one small sample

A small piece shows the color. A finished run of baseboard shows how the color reads over several meters and in a real interior.

The difference is especially noticeable if the floor has pronounced variation and the baseboard after tinting turned out too uniform or, conversely, too contrasting.

A repeat batch should be ordered by finish code and reference sample, not with the words “more of the same oak”

Weak reorder:

“Another 200 m of the same oak baseboard.”

Strong:

PLT‑001‑1 / OAK / 120 × 15 × 2400 / D‑02 / REFERENCE FLOOR‑02 / BUILDING A / FLOORS 4–5 / quantity according to cutting plan.

This is how the supplier understands that not just oak material is required, but a specific procurement version.

Why the floor batch code must be preserved in a repeat order as well

It reminds which real floor reference D‑02 was coordinated with. Six months later, the name “D‑02” without a link to FLOOR‑P02 may become too abstract.

What to keep for reorder

• physical floor sample;
• physical sample of the finished skirting board;
• code D‑02;
• PLT item code;
• material oak;
• commercial length;
• order date;
• skirting board batch number;
• photos of the area as supplementary material;
• the formulation or finishing technology, if it is part of the production documentation.

A year later, a new batch must be approved again alongside the retained reference sample

Natural wood and a new production batch make it impossible to honestly promise photographic identity a year later.

The correct process:

1. take the retained sample D‑01;
2. take the floor reference sample POL‑P01;
3. produce a new control sample;
4. compare them side by side;
5. adjust the finish if necessary;
6. only then start the full run.

So a repeat order is evaluated not from memory and not from a photograph.

If an exact match is impossible

You need to decide where the new batch will be used.

Options:

• a separate floor;
• a new building;
• a local repair;
• an area where the old and new batches are not visible at the same time.

You cannot mask a noticeable difference with the phrase “it’s natural oak, that happens” if an obvious boundary appears on one wall.

Oak PLT-001-1 should be counted specifically in the oak configuration

The current STAVROS card shows several materials for PLT‑001‑1.

For oak:

120 × 15 × 2400 mm.

For MDF:

120 × 16 × 2600 mm.

This is one SKU, but two different purchasing configurations.

Why you cannot write only PLT‑001‑1

Because the following differ:

• the material;
• thickness;
• product length;
• appearance;
• Cutting;
• price;
• the role of the finish.

For an article about oak skirting, the working line is:

PLT‑001‑1 / OAK / 120 × 15 × 2400 / D‑01.

If a different oak PLT profile is needed, its specifications are checked separately.

Why the product length affects separate cutting of trims

If D‑01 requires 820 m of clean length, simple division:

820 / 2,4 ≈ 341,67.

Mathematical minimum — 342 planks.

But real walls may require more due to length distribution.

For example, a 4200 mm wall requires a combination of 2400 + 1800 or another scheme of two original planks. The remainder from 2400 may be useful on a short wall, or it may not fit anywhere.

Therefore, the number of whole planks is determined by cutting layout, not just by dividing the total meterage.

Separating D-01, D-02, and D-03 can increase the purchase volume even with the same net meterage

Suppose the total net meterage is 1650 m.

If the entire project used a single finish, production could combine leftovers across all floors.

After separation:

• D‑01 — 820 m;
• D‑02 — 640 m;
• D‑03 — 190 m.

a D-01 leftover cannot be used in D-02, even if the size fits.

Conditional calculation

Let's assume that, based on individual cutting maps, the result was:

• D‑01 — 354 planks × 2.4 = 849.6 m;
• D‑02 — 278 planks × 2.4 = 667.2 m;
• D‑03 — 85 planks × 2.4 = 204 m.

Purchase length:

849.6 + 667.2 + 204 = 1720.8 m.

Difference relative to the net 1650 m:

70.8 m.

This is about 4.3% in this specific hypothetical example. This percentage cannot be carried over to another project. Here it resulted from specific cutting layouts.

Why finishes should not be mixed for the sake of savings

Because the goal is not the minimum mathematical waste at any cost, but a visually correct object.

Optimization should be done within each color group.

The price of oak skirting in bulk is compared only on an identical specification

Supplier A may offer a lower price per meter. Supplier B is more expensive. The comparison will be fair only if the following match:

• exact profile;
• solid oak;
• product length;
• quality of preparation;
• finishing;
• volume;
• packaging;
• marking by zones;
• terms for a repeat batch.

Why the average price across all oak is not enough

D-01, D-02, and D-03 may have different finish complexity. If the supplier gave a single average cost for 1650 m, it is useful to request a breakdown.

It shows which group is actually making the order more expensive.

If purchasing building materials at wholesale prices, oak skirting still remains a separate product line with an exact configuration.

Labeling must link the packaging to the floor, finish, and floor reference sample

The pack "PLT‑001‑1 oak" is not informative enough if there are three finishes on site.

Minimum labeling:

PROJECT / BUILDING / FLOOR / PLT‑ITEM / OAK / FINISH CODE / FLOOR REFERENCE SAMPLE / QUANTITY.

Example:

PROJECT-A / FLOOR 4 / PLT‑001‑1 / OAK / D‑02 / FLOOR‑02 / 32 PCS.

Why physical separation in the warehouse is also necessary

Even a good label does not protect against urgently issuing the wrong pack if D‑01 and D‑02 are stored mixed together.

It is better to have separate warehouse zones:

• D‑01;
• D‑02;
• D‑03;
• repair reserve.

Returning leftovers must preserve the same code

After installation, D-01 leftovers must not be returned to the generic "oak skirting" pile.

Otherwise, the next issue will destroy the entire system.

The master specification must show ordered, issued, installed, and remaining

This allows calculating the real shortage before the second batch.

Why "ordered" cannot be deducted from the project automatically

Some of the material could:

• remain intact;
• be damaged;
• go to another zone;
• remain as short offcuts;
• be used for samples.

Therefore, the new batch is based on the actual remaining stock.

Correct reorder

REMAINING SECTIONS D‑02 → MINUS WHOLE USABLE PLANKS D‑02 → MINUS USABLE OFF-CUTS D‑02 → NEW CUTTING PLAN → REORDER.

The remaining stock of D‑01 is not included in this calculation.

Practical calculation: 180 apartments, eight floors, and three batches of parquet

Let's consider a hypothetical residential project. Building A — eight floors, 180 apartments in total. The flooring was purchased in three deliveries:

• FLOOR‑П01 — floors 2–3;
• FLOOR‑П02 — floors 4–5;
• FLOOR‑П03 — floors 6–8.

After installation, it turned out that FLOOR‑P01 and FLOOR‑P02 are close, but FLOOR‑P02 is slightly cooler. FLOOR‑P03 is noticeably deeper in tone due to a different coordinated finishing system.

The project makes three control color samples and reaches a decision:

• D‑01 matches FLOOR‑P01;
• D‑01 is also acceptable for FLOOR‑P02 after on-site verification;
• D‑03 is required for FLOOR‑P03.

That is, three floor batches did not automatically turn into three skirting finishes. After a real comparison, two remained.

Step 1. Count D‑01 apartments

On floors 2–5 — 96 apartments of two types:

• apartment A — 64 pcs., net skirting length 31.8 m;
• apartment B — 32 pcs., net length 37.6 m.

Net requirement:

64 × 31.8 = 2035.2 m.

32 × 37.6 = 1203.2 m.

D‑01 = 3238.4 m of net skirting board.

Step 2. Count apartments D‑03

On floors 6–8 — 84 apartments:

• apartment A — 56 pcs. × 31.8 m = 1780.8 m;
• apartment B — 28 pcs. × 37.6 m = 1052.8 m.

D‑03 = 2833.6 m of net skirting board.

Total net volume of the project:

3238.4 + 2833.6 = 6072 m.

But a wholesale order should not become a single line: “6072 m of oak PLT‑001‑1.”

Step 3. Convert D‑01 into whole 2400 mm planks

If you simply divide:

3238,4 / 2,4 ≈ 1349,33.

The mathematical minimum is 1350 planks.

After the actual cutting of apartment walls, you get, for example, 1394 planks. Purchase footage:

1394 × 2.4 = 3345.6 m.

The difference between the net and purchased volume of D‑01:

3345.6 − 3238.4 = 107.2 m.

This is the result of a specific wall structure, not a universal percentage.

Step 4. D‑03 gets its own cutting plan

For 2833.6 m of net requirement, the mathematical minimum:

2833,6 / 2,4 ≈ 1180,67.

The minimum is 1181 planks.

After separate cutting, for example, 1219 planks were produced:

1219 × 2.4 = 2925.6 m.

The difference:

2925.6 − 2833.6 = 92 m.

Total before the separate repair reserve:

1394 + 1219 = 2613 oak planks.

Purchase length:

6271.2 m.

Net — 6072 m. The difference is 199.2 m, or about 3.3% in this specific example. On another project, the figure will be different.

Step 5. We do not divide the repair reserve proportionally automatically

D-01 serves four floors and more apartments, but D-03 may be harder to replicate a year later. Therefore, the reserve is estimated separately.

For example:

• D-01 — 30 whole planks;
• D-03 — 24 whole planks.

This is only an example of the structure, not a standard.

Final order:
