On the six painted dresser fronts, frames of 500×220 mm are already marked out: how to order polyurethane molding MLDPU-004 15×8×2600 mm and fit into four strips without short inserts

On the first facade, the frame is already laid out with painter's tape. On the second, there are only four corner marks. On the third, the craftsman applies MLDPU-004 and immediately notices that the main problem is not the profile itself, 15 mm wide, but the cutting: six identical facades require 24 finished pieces, and an error on the first plank quickly turns the calculation of "four should be enough" into an urgent purchase of a fifth.

The initial data is simple:

• 6 painted facades;

• each has a frame 500×220 mm;

• MLDPU-004 — 15×8×2600 mm;

• corners are planned at 45°;

• short composite sides in the middle of the frame are not needed.

If 500×220 mm are exactly the finished dimensions of the sides according to the pre-agreed measurement line, one frame requires:

2 × 500 + 2 × 220 = 1,440 mm.

Six frames:

1,440 × 6 = 8,640 mm.

Three MLDPU-004 strips give:

3 × 2600 = 7,800 mm.

That is, three strips are physically insufficient even without accounting for the cut.

Four give:

4 × 2600 = 10,400 mm.

By net length, four are sufficient. But the real answer only appears after the cutting map.

For this geometry, the working scheme is:

• strip #1 — 4×500 + 2×220 = 2440 mm;

• strip #2 — the same;

• strip #3 — the same;

• bar No. 4 — 6×220 = 1320 mm.

After the first three bars, we get all 12 long pieces of 500 mm each and 6 short pieces of 220 mm. From the fourth one — the remaining 6 pieces of 220 mm.

All 24 sides remain solid.

Therefore, four MLDPU-004 units are a rational preliminary order, and a fifth one is not needed automatically. But before payment, it is necessary to confirm that 500×220 mm are exactly the final dimensions according to which the miter cut will be made, and also to account for the actual kerf width and a control end trim.

If you are simultaneously selecting other decorative elements for furniture and interior, you can open the general catalog Buy moldings, but for this task, the main product remains MLDPU-004.

Polyurethane molding MLDPU-004 15×8×2600 mm: what is confirmed by the product card

The current MLDPU-004 product card confirms:

The manufacturer directly shows MLDPU-004 as a profile suitable for furniture facades of cabinets, kitchens, nightstands, and dressers.

For six already painted facades, three characteristics are especially important:

• 15 mm — visible frame width;

• 8 mm — protrusion above the facade plane;

• 2600 mm — initial length for cutting.

After checking the markings, you can order MLDPU-004 15×8×2600 mm in the calculated quantity.

Already painted facade: why dry fitting is mandatory before glue

On an untreated part, erroneous markings can still be reconsidered relatively calmly. On finished enamel, the cost of a mistake is higher.

Before adhesive installation, the frame must be checked without fixation.

Suitable for:

• masking tape with a width close to 15 mm;

• paper template;

• a short real profile fragment;

• four temporarily laid parts without glue.

The purpose of the dry fit is to answer five questions:

1. are the indents on the left and right the same;

2. is the central field not too narrow;

3. does the frame not fall under the handle;

4. does the 8-millimeter protrusion not conflict with the adjacent facade;

5. does the same frame look the same on all six doors or drawers.

If the geometry is visually unsatisfactory, it must be changed before cutting the four full-size strips.

Polyurethane molding 15 mm wide on a 500×220 mm frame: is it too large

The size of 15 mm itself does not indicate whether the frame will be proportional.

This depends on the size of the facade and the position of the frame on it.

You need to measure:

• distance from the outer line of the frame to the edge of the facade;

• distance to the handle;

• width of the central field;

• top and bottom margins;

• Symmetry.

There is no universal rule like "the frame must be 30 mm from the edge." On a small facade, 30 mm may look too wide, on a large one — too tight.

It is better to make one full-size template 500×220 mm and transfer it to each facade.

If a choice among different profiles is needed, a separate catalog is useful, where you can buy polyurethane molding already after checking the scale.

What does the frame size 500×220 mm mean

This is a critical question for the entire calculation.

The notation 500×220 mm can mean three different things:

Outer frame size

500 and 220 are measured along the outer contour of MLDPU-004.

Internal size of the light field

500×220 is the free area inside the molding.

Then the outer lengths of the parts will be larger.

Size along the centerline of the profile

This is the third system, and it has its own finished lengths when cutting at 45°.

Therefore, you cannot simply take the size drawn on the facade and automatically list 12 parts of 500 and 12 of 220.

First, on the working drawing, dimension arrows are placed and written:

500×220 — along the outer long points of the miter joints

or another actually selected base.

Only after this does the cutting map become production-ready.

MLDPU-004 on six facades: how many finished parts are needed

If 500×220 mm are taken as the finished lengths of the four sides of the frame:

For one frame:

• 2 parts × 500 mm;

• 2 parts × 220 mm.

For six:

• 12 parts × 500 mm;

• 12 pieces × 220 mm.

Total 24 pieces.

Net length:

12 × 500 = 6000 mm

12 × 220 = 2640 mm

6000 + 2640 = 8640 mm.

This is the base requirement before cutting.

Why three MLDPU-004 are definitely not enough

Three initial strips:

3 × 2600 = 7800 mm.

Required:

8640 mm.

Deficit:

8640 − 7800 = 840 mm.

And that's without:

• the saw cut;

• end trimming;

• control trimming;

• possible damage to the transport edge.

Therefore, the option "order three and try to make it fit" should be ruled out before starting work.

Furniture molding MLDPU-004: cutting layout for four strips

Now let's distribute the parts.

Strip No. 1

500 + 500 + 500 + 500 + 220 + 220 = 2440 mm

Nominal remainder:

2600 − 2440 = 160 mm.

Plank No. 2

Same:

2440 mm of parts + 160 mm of nominal remainder.

Plank No. 3

Same.

After three planks, we have:

• 12 pieces of 500 mm;

• 6 pieces of 220 mm.

Plank No. 4

Remaining:

6 × 220 = 1320 mm.

Nominal remainder:

2600 − 1320 = 1280 mm.

The fourth plank contains a large length reserve.

It is this reserve that makes the mechanical rule "add another 10–15%" meaningless for this specific cut.

Cut and 45°: why the 2440 mm map still requires verification

Inside 2600 mm, after the 2440 scheme, nominally 160 mm remains.

But the saw removes material.

Before serial cutting, the following may also be required:

• remove the transport end;

• obtain a clean base plane;

• perform a test miter;

• correct the initial machine setup.

Therefore, one cannot write that the first plank has "exactly 160 mm of allowance."

More correctly:

160 mm is the nominal remainder before accounting for all actual cuts.

Before serial cutting, the craftsman must calculate the number of cuts on their own equipment.

Why the sides of the frame cannot be assembled from short inserts

Technically, the molding can be joined in the middle of the side.

But for a 500×220 mm frame, this is a weak solution.

Additional joint:

• visible on the painted surface;

• complicates preparation;

• may show a visible line after finishing;

• disrupts uniformity of the six frames;

• creates extra risk during adhesive installation.

Since 500 mm and 220 mm fit entirely within 2600 mm without issues, it is more rational to keep each side as a single piece.

Is a fifth MLDPU-004 needed

According to the current map — not automatically.

A fifth plank may make sense if:

• the object is far away and repeat delivery is inconvenient;

• the same profile is planned to be used for other furniture;

• an operational reserve is needed;

• installation is done for the first time;

• there is a high risk of damage;

• a whole spare plank needs to be kept after the project is completed.

But buying a fifth one just because of the usual phrase "better to take extra" is not required.

First, you need to assess the actual remaining length of the fourth plank — nominally 1280 mm before accounting for cuts.

Cost of four MLDPU-004

Price of one plank at the time of check:

3 190 ₽.

Four:

4 × 3 190 = 12 760 ₽.

Five:

5 × 3 190 = 15 950 ₽.

Difference between a working set of four and buying a fifth:

3 190 ₽.

Therefore, the decision about the reserve already has a specific cost.

If the designer studies the assortment in one place, you can open Moldings shop, but the quantity of MLDPU-004 is still calculated according to the parts map.

MLDPU-004 or primed MDF MLD-004-MG

The catalog has an interesting alternative — MLD-004-MG.

The nominal geometry matches:

15×8×2600 mm.

But the material is different.

MLDPU-004

• two-component polyurethane;

• white primed surface;

• price 3,190 ₽.

MLD-004-MG

• Primed MDF;

• size 15×8×2600 mm;

• price 910 ₽ at the time of check.

You can buy primed MDF molding as an alternative option, but identical sizes do not make two products fully interchangeable.

Materials may differ in:

• edge treatment;

• behavior when cutting;

• mass;

• requirements for the adhesive;

• preparation for painting;

• reaction to operating conditions.

Therefore, the comparison is made for a specific facade and workshop technology.

Cost of four MLDPU-004 and four MLD-004-MG

Polyurethane

4 × 3 190 = 12 760 ₽.

Primed MDF

4 × 910 = 3 640 ₽.

The difference:

12 760 − 3 640 = 9 120 ₽.

This is only the difference in the cost of the original profiles.

It cannot be automatically turned into a final "project savings" until the following are compared:

• cutting;

• preparation;

• the coloring;

• glue;

• installation;

• operational requirements.

Why, on an already painted dresser, the material must be chosen together with the finish technology

MLDPU-004 is already primed for painting.

But the facade also already has a ready-made enamel.

You need to decide:

Paint the molding separately before installation

Plus — it's convenient to paint the ends.

Minus — the adhesive area and subsequent fitting require careful technique.

Install, then paint the frame

This may be rational with a certain technique, but there is a risk of working near an already finished facade.

Paint the facade and molding in one color

The color code may match, but the relief and gloss will still change the visual perception.

There is no universal sequence. It is determined by the furniture workshop taking into account the specific enamel and adhesive.

It is useful to first do a test on a small fragment.

MLDPU-004 and furniture handle: check the 8 mm protrusion before gluing

Even a thin frame has volume.

MLDPU-004 protrudes by 8 mm.

Check:

• whether the profile falls under the handle base;

• whether there is enough space for fingers;

• whether the frame passes through already drilled holes;

• whether the hand interferes with the adjacent profile;

• whether the decor intersects with the lock or other hardware.

If handles are already installed, the frame must conform to the existing geometry.

Six facades: how to achieve consistent marking

The main risk of serial work is not one gross error, but six small different errors.

Don't mark each facade by eye from the edge.

Better to make one template.

For example:

• a rigid rectangle 500×220 mm along the approved dimension line;

• four control points;

• corner template;

• same base from the bottom or top edge of the facade.

After fitting the first facade, the template is transferred to the remaining five.

This way the frames don't start to "float" across the dresser.

Polyurethane molding on drawers: checking inter-facade gaps

If the six facades are drawers, open them one by one.

Check:

• upper;

• medium;

• bottom;

• adjacent doors, if any;

• passing the frame close to the body.

This is especially important if MLDPU-004 comes close to the outer edge.

An 8 mm protrusion may be insignificant on a closed dresser but noticeable in motion.

Decorative logic of the room: when a wooden baseboard is appropriate

If the updated dresser stands in an interior with classic or neoclassical moldings, the frame can support the overall architectural logic of the room.

If the lower profile of the room is still being chosen, you can to buy wooden baseboard separately.

It is not necessary to literally repeat the material of the furniture molding in the baseboard. More important is to align:

• scale;

• color;

• gloss level;

• the character of the profile.

This node remains secondary: the article is still dedicated to MLDPU-004 and six furniture frames.

When a general catalog of polyurethane molding is useful

If after trying on MLDPU-004 the 15 mm width seems too thin or, conversely, too active, it is better to reconsider the profile before purchasing four strips.

In this case, it is convenient a polyurethane molding store, where you can compare other elements.

There is no need to try to make a specific MLDPU-004 work on the facade just because the cutting has already been calculated.

Online purchase: what to check before paying for four strips

Before buy stucco in an online store, for a specific order you need to check:

• current price;

• deadline;

• quantity;

• profile integrity;

• size 15×8×2600 mm;

• cutting map;

• approved finish.

For the project itself, the order line should be more specific than the general product name.

What to send to STAVROS manager for ordering MLDPU-004

Working specification:

MLDPU-004 / 15×8×2600 mm / 6 painted fronts / 6 frames 500×220 mm / size set along ___ line / preliminarily 4 slats / 12 parts 500 mm + 12 parts 220 mm / angles 45° / color ___ / fronts already painted / consider MLD-004-MG as an alternative yes-no.

After approval, you can buy MLDPU-004 for furniture.

When not to buy MLDPU-004 yet

It is better to postpone the purchase if:

• 500×220 mm is the size of the front itself, not the frame;

• measurement line is not defined;

• 45° angles are not drawn yet;

• handles are not installed or marked;

• front enamel is not final;

• visual scale 15 mm not verified;

• inter-facade gaps not tested;

• quantity four obtained only by dividing total footage;

• master has not yet confirmed the actual cut width.

Errors when ordering MLDPU-004 for six facades

Error 1. Buy three strips

Reason: it seems that six small frames are a small volume.

Consequence: already by pure footage, 840 mm is missing.

How to avoid: calculate 8640 mm versus 7800 mm.

Error 2. Considering 500×220 as the external dimension without confirmation

Reason: this is what is written on the sketch.

Consequence: the lengths of the mitered parts turn out to be different.

How to avoid: fix the dimension line.

Error 3. Add a fifth one only according to the 10% rule

Reason: the usual construction reserve.

Consequence: an extra plank is purchased, even though the fourth one already leaves a large leftover.

How to avoid: use a cutting layout map.

Error 4. Ignore the 8 mm protrusion

Reason: the profile seems thin.

Consequence: conflict with the handle or the adjacent facade.

How to avoid: dry volumetric fitting.

Error 5. Considering MLDPU-004 and MLD-004-MG as the same product

Reason: both are 15×8×2600 mm.

Consequence: differences in materials and technology are not taken into account.

How to avoid: compare not only dimensions and price.

Result: how many MLDPU-004 to order for six frames

If 500×220 mm are the confirmed finished dimensions of the frame sides along the accepted miter joint line, then for six facades you need:

• 12 parts × 500 mm;

• 12 pieces × 220 mm;

• total 8640 mm of finished molding.

Three strips:

7800 mm is definitely not enough.

Four:

10,400 mm — preliminarily sufficient.

Working map:

• №1 — 4×500 + 2×220 = 2440;

• №2 — 4×500 + 2×220 = 2440;

• №3 — 4×500 + 2×220 = 2440;

• №4 — 6×220 = 1320.

All 24 sides of the frames are solid, without short inserts in the middle.

At the price at the time of checking, four MLDPU-004 cost:

12 760 ₽.

The fifth plank is not mandatory because the fourth has a large nominal remainder. It is needed only as a deliberate repair or logistics reserve.

Before the final order, it remains to confirm:

1. dimensional base 500×220 mm;

2. real cut;

3. miter cuts at 45°;

4. dry fitting of the frame;

5. handles and opening;

6. painting and adhesive mounting technology.

After this, the calculation of four strips becomes not an approximate division of linear meters, but a normal production map.
