How to glue laminate

As you know, the laminate is not glued to the floor, and laid dry. Glue is needed for fastening the joints of the floor planks, which, after gluing, has a more aesthetic appearance and does not lose its qualities under the influence of the aquatic environment. How to choose glue for laminate? The adhesive to install the laminate is selected on the basis of the technical properties of the coating and the environment that accompanies the installation work. We will tell you how to glue laminate.

Consider laminate durability

Before choosing a glue suitable for gluing laminated products, it is advisable to know from which layers the board is made, produced as a result of their pressing, and what functions they perform:

• The top layer of resin of melamine or acrylate origin protects the working surface of the board from abrasion and mechanical stress. Under the resin layer there is a pattern that is applied to form a certain texture of a stone or wood.
• The carrier function is performed by a laminate board, which is a MDF or MDF board.
• Under the base there is a layer of decorative paper of Kraft type with a moisture-resistant protective coating.
• The joints of the compacted layers are treated with a wax-based mixture that performs a waterproof function.

Laminated board is divided into classes that characterize the wear resistance. They are applied to packaging with flooring. Depending on this characteristic, the type of glue is chosen in a specific way. Classes are as follows:

• 31 - laminate is designed for low loads and is recommended for use in residential buildings and apartments;
• 32 - material of average wear resistance, which allows it to be the most popular among buyers. Evidence of this - a large amount of video on the installation of this product;
• 33 - the coating withstands considerable loads and is used in public premises.

Installation of laminate flooring takes place on a special substrate with a conventional locking compound or a tongue and groove method.

Note! The use of glue provides additional protection of the material from moisture damage. After dismantling, it will no longer be suitable, and if a defect is formed on one of the layers of the board, all material will have to be removed and replaced.

Adhesive laminate mounting method is good because when it is used, the joints between the slats do not allow moisture and other aggressive media during operation. Therefore, to begin with, it is desirable to find out more information about the properties of adhesive mixtures for the laminated coating.

The composition and properties of glue

Adhesive formulations are of the following types:

• water-based adhesive mixtures,
• synthetic resinous adhesive compositions,
• adhesive compositions based on polyurethane of 2 components,
• polymer adhesives.

Note! PVA glue is contraindicated for gluing joints of laminate products, as it contains water that damages the coating.

Water-dispersed glue mixes are excellent for bonding elements of this floor covering. With the help of glue laminate is laid in a floating way, i.e. only joints are glued, the laminate panels are not glued to the floor. The cost of such adhesive mixtures depends on the manufacturer and the additives used in the manufacture.

Обратите внимание! Монтажные работы с применением клея должны происходить при невысокой влажности и температуре воздуха >15? С.

Synthetic resinous adhesive compositions according to the documentation have moisture resistance, strength and durability. But these adhesive mixtures are used only for the installation of lamellas, whose thickness exceeds 1.4 cm. Such glue well complements the joint, made by the locking method.

Glue compositions based on polyurethane of the two components are considered the most popular. This glue quickly sets, has excellent adhesion, dispenses with pre-assembly primer. The main binding role in the adhesive composition is played by polyvinyl acetate with cross-directional bonds, which contributes to the durability and strength of the flooring.

Polymer adhesive, which is used to install laminated products, is not composed of water and solvents. The documentation states that it is possible to use such an adhesive if the foundation is firm, even and dry.

Criteria affecting selection

Choosing how to glue the laminate, you should learn as much as possible about the properties and composition of the adhesive. Glue mix for laminate must have certain properties:

• the main factor that is taken into account when choosing an adhesive composition is the lack of response to the aquatic environment;
• to ensure the strength and quality of the laminated coating, excellent adhesion is required;
• stains and drips on the genital surface are unacceptable. They should be removed without complications;
• glue should not be affected by freezing temperatures. Documentation must be mentioned about this;
• adhesive composition should not harm the environment;
• glue must ensure durability and strength of the coating.

Before gluing the edges of the lamellae, it is necessary to get rid of dirt on the surface of the coating, if any. The place of application must be degreased with a special compound. The places on which the glue will be applied should be treated with sandpaper. After bonding, the parts to be glued must be firmly pressed together for at least a quarter of an hour.

Choosing glue for laminate, you need to pay attention to the manufacturer, shelf life and environmental safety. The market offers many adhesive compositions at affordable prices and with good quality. Therefore, the acquisition of a good adhesive for laminate today is not a problem.
