Diagonal Laminate Installation: DIY Laying + Video

Diagonal Laminate Installation: DIY Laying + Video Diagonal laminate - how to lay? See photos in the interior. There are two main methods of installing laminate flooring - diagonal and straight. The second option is suitable for those who are new to this business, and it is only suitable for rooms that are narrow and stretched in length. If your room is more square, then it is possible to lay out the laminate diagonally.

We will tell you how to do it right.

Advantages and disadvantages of the method

Very often, when laying the laminate diagonally, the laboriousness of the process and the complexity of the calculations are noted. Yes, in this case, you will have to use more material, since there will be several times more waste (scraps) than with the classical method. But there is also a positive moment: chic appearance and showiness in the interior. This way of decorating the floor looks much more interesting.

Diagonal technology makes it possible to achieve a visual expansion of space in the room, which will be an advantageous solution for owners of modest living space.

This solution looks especially attractive in places that are not cluttered with furniture and other items. Any drawing can be done, and any professional finisher will use it. And also, responsible and result-oriented builders will not complain that it is difficult, as they are also “for” the style and original design.

Diagonal Laminate Installation: DIY Laying + Video Please note that the type of design is "diagonal laminate" it is even easier to fit into rooms with complex shapes than using the standard method. But it should be borne in mind that the master will take on this work only with an increased pay, since each of us values ​​our strength and time.

How to lay the laminate diagonally


Material consumption when laying the laminate diagonally - a very important topic that requires the most accurate calculation and cutting. Ideally, the laminate should be cut into more than three rows of panels. If you are preparing a large number of blocks, number each so that when laying on you forget which segment should be in which place. Since there are not completely right angles everywhere, it will be correct to estimate the trim angle just by trying on the material. The laminate that will be laid over the ledge, recess, pipe outlet should be cut according to cardboard templates.

No matter what method you choose to install your laminate, you should pay special attention to surface preparation. First, you should treat the floor with mixtures for leveling to the "perfect" state, remove all debris and interfering objects. Before laying, sweep the subfloor once more, reinforce it with a primer, and then place a cellophane film on the floor and cork sheets or underlay on top. After that, you can start the main part of the work.


How to lay the laminate on a diagonal?

General rules are :

  • The laminate must be indoors for at least 24 hours prior to installation.

  • The laminate must be leveled.
  • After it is strengthened.
  • The base of the material should be cleaned.
  • A substrate is laid on the floor.
  • Prepare wedges for expansion gaps (wood blocks or laminate trim, ideally wedges should be 1-1.

    5 cm wide).

Laying the laminate diagonally from corner to corner requires a rectangular triangle to be drawn at the beginning on the back of the boards (the angles of the figure can be adjusted depending on the straightness of the joints on the walls in the room). In this case, your drawn hypotenuse should "look" in the direction of the groove. Next, the cut out figure is placed in the corner and wedging is done so that there is an interval.

Hint: do not rush to throw out the remaining boards, as they can be useful when laying in the second half of the room.

When you have a gap, choose a solid panel from the groove side towards the tongue and draw a 45 degree line. Next, from the end point we lay a segment, its length should be the same as the base of the triangle. Connect the second point to the base (again at 45 degrees), and you should now have an isosceles trapezoid. If you follow these simple principles, you can achieve excellent results even without special skills and abilities.

Tools and devices

Laminate sawing is done with any object convenient for you with fine teeth.

According to the recommendations of experts, it is better to use special machines or an electric jigsaw, you can try with a circular saw. But if you do not want to learn how to use these tools when repairing, it is better to actually purchase something from this list than to use metal saws and hand saws.

In addition to the basic tool, you will also need:

  • Construction tape.
  • Hammer.
  • Wedges for creating gaps.

  • Padding block.
  • Pencil, ruler to measure out short pieces of material.

Material consumption - calculate the quantity to buy

Diagonal Laminate Installation: DIY Laying + Video Approximate The material consumption is quite simple to estimate: you know the area of ​​the room in m 2 , add another 15% to this figure and divide by the area of ​​a single panel. If you are not satisfied with this calculation, there is a more accurate formula. Label the length of the room as X, the width as Y, and label the length and width of the laminate panels as A and B, respectively.

Next, we calculate the area of ​​the room (for this we multiply the length by the width, X * Y). To calculate the margin, multiply the width of the room by the width of the panel and by 1.42 (Y * B * 1.42) - this way you will get the area for which you should definitely have enough material, if you do not cut it off at all during installation.Next, we sum up both figures, divide the resulting amount by the area of ​​one panel block and round up.

Important: the area of ​​the room should be prepared and again talk to the seller in the hardware store, how much it costs to take the coverings, otherwise you may miss and buy more than you need, or less (and no guarantees that when you return to buy laminate flooring, its stocks will still be in the fold - not only you are doing repairs).

Laying technique

Laying the laminate diagonally has three main varieties:

  1. We start from the corner, the first element will be a right-angled triangle.
  2. Laying begins with an indent from the corner, your original piece is a trapezoid.
  3. We start laying from the middle of the room, from the line that diagonally crosses the whole room, the first row is prefabricated.

Diagonal Laminate Installation: DIY Laying + Video But most often work starts from the corners, which is located farthest from the entrance, and when you work you should move from left to right.

We lay the initial row away from ourselves with a comb and onto ourselves with a groove. If you will be using standard panels with a typical lock, first place them in the same plane, and after laying the wooden underlay, hit the panels with gentle blows of a wooden mallet. Since it is easier to drive the spikes into the groove, you should not do the opposite, and do the work from one corner to another.

When you have several panels in a row (and this happens often), you can either add them one at a time, or immediately make a chain and fix it as a prefabricated structure. If you are laying blocks with latches, you do not need to knock them in, it is better to make a double-sided docking, which will go from the middle or from the indentation.

When using the trapezoid method, it is necessary that the length of the smaller base is not more / less than the length of the larger base of the previous one. If you do not have enough one panel to close the gap between the walls, assemble in rows, and the corners can be cut in advance, but only for those blocks that complete the chain.

You can also lay the laminate diagonally with your own hands if you connect opposite corners with a diagonal strip that is drawn on the substrate. If this method is difficult for you, there is a way to simplify - hammer nails in the corners or install self-tapping screws, and then pull a string or string between them. It remains to measure the angle that separates the diagonal from the nearest wall - it will show you which panel to cut first.

It should be placed with its wide part on the marked line, and the field should be fenced off from the wall with wedges.

We attach as many panels to the initial block with their ends as required, and only at the end of the row will a cut at a certain angle be needed. Here, each tier will duplicate the previous one, but the cutting is done so that the seams run away and in no case coincide.

Attention! Only suitable elements should be used to the right and left of the middle, if there is no threshold between several rooms and each of these rooms will have the same covering, trimming the laminate is not necessary. But panels that do not fit in one room will be immediately connected to others.

Laying the laminate diagonally with the lock in the tongue-and-groove format should be used only in one direction, while from the corner; if you purchased a cover with snaps, then this does not play a special role, and other chains can be attached to the previous ones from different sides.

If you start working from the middle of the room, leave the installation of small fragments for dessert so that there is no waste of material. Expanding wedges are installed from the walls to the edge of the panels, which will need to be removed - they are needed to avoid immediate surface adhesion and the creation of an expansion joint.

Important: Make sure that the walls do not narrow for the entire period of work, as then alternate laying will begin.

Finally, part of the formation is turned into a source for the opposite segment.

When laying diagonally, attention should be paid to specific features. Often there are problems with goods from such manufacturing companies as:

  • Diagonal Laminate Installation: DIY Laying + Video "Kronotex".
  • Vitex.
  • Tarkett.
  • Pergo.

  • "Berry Flour".

Each of these manufacturers has its own design methods, which affect the specificity of the offset, the size and type of the lock. If you suddenly find it uncomfortable to secure the blocks, the simplest solution would be to create rows with alternating short and long locks.

"The most convenient cutting option is from the inside out and with a jigsaw, as this makes it possible to avoid chips on the outer surface"

Laying the laminate diagonally over cement and even screeds should be started no earlier than a week after application. In winter, if there is a heating interruption, you should wait all 3 weeks.

In order to level wood floors, use OSB slabs, isolon or a substrate.


If you want to expand the space visually, it will be useful to put a laminate on the walls, and leave the middle of the room for linoleum of the same shade.

The combination of panels of different, contrasting shades will look great - this will add expressiveness to the floor. The main accent is advised to be introduced into the corner parts of the coating.
