Polyurethane glue for wood: selection and tips for use

When evaluating different types of adhesives, it can be difficult to choose the right one. This is especially true when working with wooden surfaces. When choosing the best option, the characteristics of the wood itself and the characteristics of the material to which it will be glued are taken into account. You also need to know about the loads that this seam must withstand.

In this case, the use of polyurethane glue will be quite justified. This type of composition has long been used in all European countries, and in Russia it is only gaining popularity.

Polyurethane adhesive is an excellent product for working with wood, rubber, metal, stone, marble, PVC, MDF and mosaics. It stands out among its analogues for its excellent sealing properties. In a frozen form, such a composition is good heat and sound insulation. In addition, with its help, the gluing of different materials occurs quite quickly.

Polyurethane compounds are often used for interior decoration: in kitchens, bathrooms, restrooms and balconies. In external decoration - for cladding facades or roofs. In industrial premises, such glue is used less often.

The main advantages of polyurethane glue:

• high level of adhesion;
• able to withstand large temperature ranges;
• heat resistance;
• easy to use on porous surfaces;
• moisture resistance.

When working with polyurethane glue, the surface must be free of dust and dirt. The applied layer should not be more than 5 mm. When hardening, it is best to lightly press the element against the surface.

Polyurethane adhesive mixtures are available in one- and two-component. You need to know the difference between these formulations. The action of the two-component glue begins immediately after mixing all the components. The disadvantage is that a special mixing container is required. The one-component composition is already ready to work. It does not begin to freeze immediately, but only half an hour after opening the package - this gives time for preparation, does not force the master to rush. Such glue begins to set under the influence of moisture or humidity in the air / surface.

When choosing an adhesive, it must be borne in mind that there are many different types of adhesive mixtures on the market. They have different properties and qualities, so you need to pay attention to the most popular ones.
