Instruction and In what two ways is the installation carried out? + Video Laying parquet in order for it to last a long time, it is best of all on plywood. This still needs to be done, because the price of parquet is quite high and often you cannot change it. But what kind of plywood is better for a parquet board.

Parquet boards are laid on plywood and not only, but also laminate, linoleum and tile. This measure is used in order to achieve a level surface under the parquet board.

For parquet, it should not be more than two percent per running meter. Parquet is quite sensitive to moisture, and plywood will be a dry substrate that will not deform the parquet. In individual cases, the parquet board can be installed directly on the concrete floor. But the concrete floor must be self-leveling and waterproof.

What is plywood for?

Before you start laying parquet boards, you need to know the exact humidity in the room.

Humidity is usually measured with a special device. But if it is not there, then it is necessary to cover the concrete screed with ordinary construction film.

The film should be left in this position for about a day. After this time, you need to assess the condition of the floor and oilcloth. If condensation appears on the film, and wet spots form on the screed, then even with a good screed, it is best to use plywood as a base for the floor.

How to lay plywood?

Plywood has a large number of advantages and thanks to which this material has not lost its popularity in construction. Plywood is made of natural wood with added stabilizing components. But not all plywood will fit a parquet board.

The following plywood parameters must be taken into account:

  1. Instruction and In what two ways is the installation carried out? + Video Sheet size;
  2. Thickness;
  3. Resistance to moisture.

It is best to use sheets with a thickness of at least ten millimeters under a parquet board.

This plywood will not allow the parquet board to bend. The size of plywood for parquet is selected individually. This will depend on the size of the room.

The grade of FC plywood is moisture resistant and therefore we can recommend it. It is in the material of this brand that the environmental friendliness of natural wood and glue, which does not include formaldehyde, are combined.

When using plywood of this brand, you do not have to worry about the fact that the plywood under the parquet board will not emit harmful vapors that can have a bad effect on human health.

Important! When choosing plywood for parquet, it is best to opt for plywood made from softwood. Due to the fact that conifers have essential oils in their composition, which protect against the effects of various pests.

Laying plywood under a parquet board on logs

Laying a log under parquet boards, it is possible in any room. In the event that the room has an old wooden floor, then it is worth removing it and assessing the state of the lag.

Maybe some of them will need to be replaced.

If you leave old logs, then you need to clean them and treat them with an antiseptic, which will not allow the tree to rot, and also prevent the appearance of parasites. After inspection, the concrete floor must be repaired. All cracks in concrete can be repaired with tile adhesive, then a primer must be applied (the primer is applied in several layers).

Then you need to find out the level of the floor drop, this is necessary in order to know how to lay logs.

In order to find out the level of the floor drop, use a level. With such a device, you can project lines on all walls and use a tape measure to take measurements in any part of the room.

Instruction and In what two ways is the installation carried out? + Video The data must be written into a notebook. Measurements made in this way will allow you to accurately find out the level of the floor drop. When the primer is completely dry, you can start laying the waterproofing.

A membrane or film with a thickness of two hundred microns can act as a waterproofing. The membrane must be placed on the right side so that condensation does not collect under the plywood. After everything is prepared, you can start installing the lag.

In order for the logs to hold for a long time and firmly, it is necessary to attach them to the concrete floor with a puncher on the anchor bolts. The caps of the anchor bolts must be sunk so that they do not protrude from the top of the log.

After the logs are laid, you need to take care of sound insulation. Stone wool is used as sound insulation, it is placed in the niches that appear.

Another layer of waterproofing can be laid on top of the cotton wool. Next, we make a template in the form of a square, but we will cut the plywood into it. This template can be made from a large sheet of cardboard.

The template is needed in order to determine the required size of a plywood sheet, which can cover the entire space with minimal loss.

Important! The step between the lags should be thirty centimeters. Lay the plywood so that its edge lies in the middle of the log. New logs will need to be treated with an antiseptic.

After the plywood sample has come up, you can start cutting the plywood.

Plywood is cut with a hand-held circular saw or jigsaw. Before screwing the plywood to the joists, it is best to spread it out over the entire floor area and see if the plywood will cover the area as planned.

It is better to number the plywood sheets, this will help in the installation. If necessary, the sheets can be swapped. Plywood sheets are screwed in such a way that the caps of the screws are sunk into the plywood sheets.

Plywood sheets are mounted in a checkerboard pattern.

Important! The first lag is laid with a gap from the wall and thus plywood is also laid. The gap should be five millimeters, then cover it with a baseboard. Such a measure will prevent the floor from lifting.

Laying on the screed

Laying plywood on the screed begins with assessing the humidity of the room.

The floor surface must be flat. Differences in the plane are detected in the same way as with laying a lag.In the event that the parameters do not exceed three centimeters, then self-leveling mixtures are used for leveling.

After that, the elimination of shortcomings is carried out and then primed. If the screed area is large, then it must be divided with polyurethane foam into separate contours.

The self-leveling mixture is diluted according to the instructions on the package. Air bubbles that may form after pouring are broken with a needle roller.

The screed must gain strength and then it is treated with a primer, dried and only after that plywood is laid.

Film will act as a waterproofing for plywood. Self-tapping screws and dowels are used for fastening, and this involves drilling holes in the floor, but there is another way of fastening.

The plywood can be applied to the mastic. In this case, it will not be necessary to drill, but the mastic itself acts as a waterproofing. Do not forget about the interweaving of seams like brickwork. Well, we told you which plywood to use and how to install it. Plywood can be bought at any hardware market or hardware store.

If you cannot install plywood yourself, then contact a specialist. We wish you good luck and patience.
