In addition, the ratio of the width of floor plank (of any tree) to its thickness should not exceed 3-3,5. German glue stauf M2A-720″ on properties similar to glue a “B-720”. There is another variety of aquatic adhesive solution – two adhesives. These solutions are considered the most modern. The action of adhesives based on the use of emulsion adhesive and binding excessive moisture powdered composition. Clay bona H-790 consists of an emulsion or powder.

Before use, the components are mixed. Powder binds excess water, leaving only 11%. This adhesive can be used for any type of flooring, without restrictions. Dispersion adhesives dry out completely in about 7 days. In Russia, the aqueous dispersion trains are not a great success: they may freeze during transport, then their properties are somewhat worse. Solvents, adhesives have the widest application.

They harden faster dispersion – 5 days, the polishing of parquet is usually possible to start even earlier. In addition, their use in cases where there is no technical the possibility of using dispersion adhesives. For laying parquet best fit the following brands: bona 8-760, stauf WFR-4, uzin MK-73 and MK-97. They are all high quality, about the same kind and price. Quite a long time may be in the open state (15 minutes), which facilitates their use. Due to the high turnover of adhesive laid parquet can be partially tinker even after laying adjacent rows. But keep in mind that all adhesives solvents, fire risks, so work with them to be careful, away from open flames. Naturally, in any case you can not smoke in the room during the use of glue on the well-ventilated place and in tightly closed containers. Two component adhesives are also called reactive because they contain no water, no solvents, and bonding occurs due to chemical reaction, non-shrinking. Such adhesives are a number of advantages over others: they used for bonding parquet to any any reason, they are about three times stronger and freeze for a day so that you can grind on the next day. But there are also disadvantages. First of all, of the adhesives include adverse health component, so when the work is necessary to use personal protective equipment. Once the glue has hardened, it is perfectly safe. Another drawback of reactive adhesives is their high price. Reactive adhesives are typically used where the use of other types of glue inappropriate. For example, when laying a solid board, because of its large size, even in the application of adhesives solvents linear deformation is very high, moreover, requires greater bond strength. In addition, there are parquet, which is already factory-varnished. And in that case you can not use alcohol-based adhesives, the more dispersive. They can cause a dissolution, cracking paint and warped flooring.
