Screed laying parquet without plywood

Parquet board is a natural, practical and beautiful option for flooring. An important stage is not only the selection of the product, but also its styling. There are various ways to place parquet indoors. Sometimes plywood is used when laying. You should understand why it is needed, whether it is possible not to use it when laying parquet on the screed and how to correctly conduct the whole process.

Why do we need plywood

Plywood is used not only for parquet, but also for other coatings, including tiles and linoleum. It allows you to achieve a perfectly flat surface. This has a positive effect on the future use of the floor and its service life. In addition, the parquet is highly sensitive to temperature extremes. Plywood acts as a dry substrate and does not allow the product to deform.

Reference! Before laying it is recommended to assess the level of humidity in the room. To do this, use a special device. This will assess the condition of the room and the need to use an additional substrate.

How to lay parquet without plywood

The base of the floor requires careful preparation, especially if it is not planned to use plywood in addition. The screed must meet the important requirements:

  1. Allowable in front of the height varies in the range of 1-3 mm per linear meter. To determine this parameter, use a special level;
  2. Humidity should not exceed 3%.

Any irregularities and cracks should be disposed of. If the humidity is high, it is recommended to place a vapor barrier on the floor. The concrete base needs to be ground and primed. This will add reliability to the base. Use concrete screed - the most popular base.

REFERENCE! For laying, you can use the adhesive and floating method. It is recommended to understand each of them.

With the adhesive method, the product is attached to the base using an adhesive composition. Elastic glue is more suitable. The process consists of the following steps:

  1. The surface is treated with a primer;
  2. Take the boards for the first two rows and lay them as they are supposed to be and should lie. Glue is applied to the product and base;
  3. The first board is laid on the base, departing from the wall by 10-12 mm;
  4. Using a special bar, you should knock the second board to the previous one. Glue each product for a maximum of 10 minutes, otherwise the glue will dry out;
  5. If necessary, the last board is cut and the next row begins with this remainder;
  6. For convenience, it is recommended to insert small wedges into the space between the floor and the wall;
  7. The described algorithm should be performed somewhat side by side. Then it is recommended to check their quality. There should be no cracks, the surface is flat.

When the floor is completely covered, the resulting seams are treated with a sealant with an acrylic base.

The floating method is characterized by the absence of seams. This effect is achieved due to the compression of the floorboard. To do this, use the lock method or glue. Unlike the previous method, the product does not stick to the base, but to each other. Installation looks like this:

  • Laying starts from the left corner. The board should be placed lock to the wall. The side adjacent to the wall should be without grooves. It is recommended to cut them;
  • The second product is placed at an angle to the edge of the previous board;
  • As in the previous case, the next row begins with the remnants of the product from the past. If the board is less than 30 cm in length, then it is better to take a new one and saw off half of it;
  • It is necessary to continue in the same order until the work is completed.

To keep the product tighter, it is recommended to use a rubber mallet or wooden hammer. The floating technique is more suitable for small rooms. If the room is large, the floor will begin to creak, a high probability of curvature.

Finally, sand the surface. If cracks are present, they must be putty. When everything dries, re-grind the floor. The final step is the priming and varnishing of the surface. This will protect the floor from damage and cracks and make it more beautiful.

What is fraught with the lack of plywood

It was noted that the use of plywood is not mandatory when laying parquet boards. However, it is worth noting what negative aspects can arise if you refuse plywood. Her absence is fraught with:

  • Curvature of the floor. If the base is not even enough, then over time the board will simply distort and the aesthetic appearance of the room will be immediately disturbed;
  • Lack of additional thermal insulation. Plywood can be an additional source of heat. Otherwise, the floor will be extremely cold.

Plywood is also an excellent base for reliable gluing of boards. Therefore, it allows you to create a strong connection that will last a long time. If its use is not planned, it is imperative to take into account many factors, including the evenness of the base and the level of humidity, in order to lay the parquet efficiently and correctly.
