Which glue is better for laying parquet, the best brands and manufacturers
Parquet is increasingly used as a floor covering. However, it must be applied correctly to obtain a very good result. An important role is played by glue for laying parquet. It is the adhesive composition that affects the installation and then the duration of use of these floors. The choice of substances is huge, therefore, before buying, it is recommended to carefully study the composition and method of application.
General requirements for parquet glue
There are a number of requirements for parquet glue. Properly selected glue will allow you to achieve the desired result - a well-laid floor and its durability. Otherwise, squeaking and even peeling of the coating may occur, which will require further repairs, a great waste of time and money.
Minimum shrinkage
Parquet glue is used in a liquid state. An important indicator in this case is its shrinkage after drying. It should be minimal.Otherwise, the sagging of the parquet slabs and the appearance of unpleasant sounds in the future are not excluded.
Elasticity
An important indicator of the quality of the glue is its elasticity. Parquet has several properties - it reacts to temperature, expands and contracts, and is able to absorb moisture, which then evaporates. As a result, the size of the board changes periodically. A good adhesive should compensate for any changes.
If the substance is of poor quality, after a while the floors will begin to crack and peel.
Long life expectancy
Natural parquet is one of the most expensive floor coverings. Such boards are not affordable for everyone, the installation cost is also high, so it is quite understandable that the owner wants the floors to serve for a long time. Using poor quality glue will result in reduced service life. If at least one board peels off, several of them will have to be replaced at once, since it is impossible to dismantle such a floor without loss. Repair or complete replacement of the floor will be necessary.
Minimum amount of water
Parquet glue is always liquid. But the water content should not exceed the permissible value. The boards absorb moisture quite strongly. Using a poor quality adhesive will cause problems with the flooring. As a result, the entire floor will have to be redone.
Respect the environment
The adhesive always contains chemical compounds. Some of them have an unpleasant odor and can release toxins into the air. Therefore, the environmental friendliness of the product is considered an important factor.The quality of parquet glue is controlled at the state level, so only a safe product is found in stores.
Varieties of adhesives
Different companies offer products of different composition and quality.Several groups stand out, united by common properties.
Dispersive
Consumers in European countries prefer dispersion glue for parquet. The product is considered environmentally friendly due to its low toxicity. The basis is water, therefore the vapors resulting from the solidification of the substance do not contain harmful compounds and do not have a negative effect on human health. This property allows the use of dispersion adhesives in any living space.
The assortment of the product is quite large, the substance differs in water content, composition and cost.
Dispersion types are well suited for laying oak parquet due to the fact that this tree is more resistant to moisture. It is better to lay beech, alder or fruit tree floors with a different adhesive so that they last longer and do not warp.
Synthetic
The substances are based on synthetic resins and rubber. Such glue hardens quickly enough, but has weak adhesion properties. Therefore, special attention is also required for the screed and the primer. It is recommended to use it for natural wood floors.
Bi-component
Two-component adhesives have increased strength, but the price of such products is also not low. They got their name because before use they combine two ingredients - an adhesive and a hardener. In the liquid state, the product emits harmful vapors, therefore it is recommended to use personal protective equipment when working.
After curing, a hard material with low elasticity is formed, so the scope of application is not too wide.
Polymer
The glue is based on specific polymers. There is a rather unpleasant smell when using it. Curing takes place under the influence of air humidity. The disadvantage is the long curing period. In terms of indicators, it belongs to the middle group of all adhesives.
One-component polyurethane
The glue of this group has good elasticity and does not pass moisture. The substance can be used when laying parquet, suitable for plywood. The glue can be used with any wood, it dries quickly and prevents the slats from swelling.
Choice criteria
The choice of parquet and glue depends on several factors. Several criteria must be taken into account to obtain a durable floor covering. It is recommended to pay attention to the following characteristics:
- The increased load on the floors implies maximum connection to the concrete base, therefore a two-component adhesive should be chosen.
- With a board width of more than 12 centimeters, the risk of loading the sides increases. In this case, a glue with increased elasticity and strength is a good option. It is better to give preference to polyurethane products.
- If the width of the board is less than 12 centimeters, then the choice of glue depends only on the preference of the master and the purpose of the room.
Whichever parquet you choose, it should be remembered that a properly prepared surface plays an important role. Floors should be level and well prepared. In this case, the glue is chosen taking into account the floor used in order to ensure the best adhesion of the boards and the concrete.
How to choose a primer
The choice of primer is very important in renovation. Such substances normalize the absorption of glue and make the surface more durable. In the absence of a primer, the risk of future problems with the parquet increases significantly. To obtain durable floors, it is recommended to purchase a primer and glue at the same time, the substances must be absolutely identical. In this case, the likelihood of problems with the parquet is significantly reduced.
Review of popular brands
There are many brands of parquet glue. Some of them are more popular due to their quality and price.

How to use correctly
Before laying parquet, it is necessary to check the temperature and humidity of the concrete screed, especially in the corners.Full hardening of concrete occurs after a few weeks. Prepare the glue according to the instructions, then start laying:
- A primer is applied to the concrete while waiting for complete drying.
- Previously, it is possible to arrange the parquet as it will be glued.
- Glue is applied to the base using a comb trowel slightly larger than the size of the board.
- Lay the parquet, press lightly. Excess glue is immediately removed.

Professional tips and tricks
Parquet installers recommend taking into account not only the opinions of friends and reviews on the Internet when choosing an adhesive for parquet. A silane or rubber based product is not always suitable for flooring. It is necessary to take into account the type of wood, the concrete screed, the primer used.
It is recommended to consult with the master before buying, take accurate measurements of the area and take into account the purpose of the room. It is better to entrust the work to a specialist in order to achieve a positive result and avoid parquet problems in the future.
