Two-component glue for parquet: what is it?

Parquet flooring is a floor covering, which consists of separate elements, which are necessarily fastened to special glue. Regardless of which type of parquet is laid, the adhesive provides the necessary strength of the connection. Modern industry produces glue for parquet, meeting all modern requirements of ecological safety, that is, it does not allocate any toxic components.

You need to choose the glue for parquet very carefully. Although it is not very expensive, but its value in the reliability of the floor is large enough. The glue for a parquet has the same value, as well as a good foundation for a house. Why? Because the parquet after laying for a long time is cyclically subjected to expansion and contraction in the process of the natural reaction of the tree to changes in humidity and ambient temperature. These changes lead to a significant strain between the bars. Parquet, which is not attached to the floor, can be detached from it, functional and cosmetic defects are formed.

To floor the floor for a long time pleased its owners, it is necessary to resort to the use of glue, but not simple, and specialized glue for parquet, which is capable for a long time to retain its elasticity after drying.

What should be the glue used for parquet?

To ensure that the parquet is able to perform all its functions for a sufficiently long period of time and does not require additional care in the future, the glue must:

• To be distinguished by good adhesion to any material from which the floor is made (wood, concrete, marble and others). This characteristic is responsible for how quickly and, most importantly, can qualitatively "grasp" the parquet.
• Dry in a short time.
• Be economical, that is, the consumption of glue is small.
• Serve for a long time.
• Do not lose its characteristics even with a fairly wide temperature range.
• Be environmentally friendly.

Variety of species

Manufacturers today are able to offer a huge assortment of glues, with which you can lay parquet. All of them can be divided into three large groups:

• Resin adhesives containing alcohols;
• Reaction glues (can be single- and two-component);
• Dispersive adhesives, which are made on a water basis.

PVA almost always acts as the basis of most adhesives. Other substances that make up the mixture, compensate for its shortcomings. So, let's consider the most popular types of parquet adhesives.

Glue for parquet one-component

Multi-layer, mosaic, piece and many other types of parquet can be laid thanks to this glue. It is great for working with any kind of wood. This kind of glue is not able to destroy the decorative coating of the parquet and, if necessary, after hardening, can be removed from the surface without any consequences. It can be polarized by contact with water that is contained in the air.

Two-component glue for parquet

It contains no solvents, amines, water and freezes after all components of the glue are mixed. He does not have any smell. Two-component glue for parquet is the most durable glue. It perfectly suits both for piece parquet and parquet board, and for joining concrete and plywood.

This kind of parquet glue in its composition contains 2 parts, which must be mixed before use. Traditionally they have the name composition A (epoxy-polyurethane or polyurethane polymer) and composition B (hardener). Their proportions are 9: 1. The manufacturer usually indicates in what proportions it is necessary to mix them before work, and should strictly follow the instructions. For joining compounds it is preferable to use a special drill bit or mixer. As a result of all manipulations, an elastic glue mass is obtained, which must be uniform in color and structure. Ready-made glue for parquet can be white, beige, brown or even black.

Benefits

• The main advantage of a two-component adhesive is a high-strength compound formed after the glue has hardened (usually within 24 hours).
• Good adhesion to any kind of surfaces.
• In its composition, this type of glue has no solvents and water, it can be used to work with such difficult tree species as ash, birch, cherry, beech, apple, maple. When exposed to water, the wood of these rocks is prone to deformation, so the use of a two-component adhesive in this situation is an excellent choice.
• The glue is not exposed to bacteria and mold.
• Two-component glue is a reactive compound, the gluing process occurs as a result of a chemical reaction between its components. It also has a high degree of elasticity.
• Versatility.
• The glue does not spread.

The disadvantage of this type of glue is the limited time of use of the mixture - only 2 hours and a sufficiently high cost.

There are several types of two-component glue:

• Polyurethane adhesive can be used for all types of wood. It has good elasticity, its indices are in the range of 30-40%. Polyurethane adhesive for parquet is almost odorless and does not contain harmful substances in its composition. There are firms that produce an eco-friendly and hypoallergenic appearance of this glue.
• Epoxy-polyurethane adhesive in the composition has an epoxy resin. The adhesive is inferior in elasticity to the first species, the index of its elasticity is in the range of 15-20%. The disadvantage is the presence of an unpleasant odor, so after the work is completed, it is necessary to ventilate the room. However, the cost of epoxy-polyurethane adhesive is much lower.

Application conditions

If the ambient air temperature is lower than 15 ° C and humidity is higher than 65%, then two-component glue should not be used. In winter, parquet and glue must be pre-recorded in the heated room and the materials to keep warm.

Two-component glue for parquet, reviews of which are only positive, has proved itself in professional builders, but it is also appreciated and preferred by ordinary people doing home repairs themselves.
