Barlinek engineered wood flooring – glue-down installation
Purchased packages of wooden floors should be placed horizontally in the room where the Barlinek board is to be laid for a period of at least 48 hours, in the original packages. The humidity of the substrate should be up to 2% for cement, up to 0.5% for anhydrite measured with the CM method. The relative air humidity of the air should remain within the range of 45% and 60% and the air temperature during installation and use within 18°C and 24°C (64.4°F and 75.2°F).
Engineered wood flooring installation – glue-down laying
The purpose of installing a wooden floor using a glue-down method is to immobilise it and permanently bond it to the substrate so that in the future, during its many years of use and various loads on the floor, there will be no defects. A glued-down wooden floor is much easier to renovate / sand. Glue-down installation of the wood floor increases acoustic comfort in the room, the floor is quiet and walking sounds are less audible.
Solvent and dispersion adhesives cannot be used. One-component adhesives are recommended: PU (polyurethane), MS (silane), MSP (MS polymer) designed for engineered wooden floors which are finished during the production process.
Engineered wood flooring installation glue-down laying
When installing a wooden floor, do not place an underlay on the glue. The only element between the substrate and the floorboard is glue.
Likewise, when installing using a floating floor system, it starts with the preparation of the substrate. Make sure it is even, measure its humidity and check its strength.
The substrate for layered boards should meet the following strength requirements:
– strength of the underlay on the wall 1.2 N/mm2
To lay a wooden floor using the glue-down method, you need tools, however, with the difference that the additional tool is a notched trowel (here we recommend B11 trowel, in which the spacing between the teeth is exactly 11 mm). The glue efficiency when using a trowel with such a teeth spacing is approx. 1 to 1.2 kg/m2.
Solvent and dispersion adhesives cannot be used. One-component adhesives are recommended: PU (polyurethane), MS (silane), MSP (MS polymer) designed for engineered wooden floors which are finished during the production process
Having the substrate prepared in such a way, it is necessary to start priming it. The primer must be prepared in accordance with the manufacturer’s recommendations. Using a paint roller, apply it evenly to the substrate, avoiding puddles. If you use Barlinek primer, you can start gluing after 120 to 150 minutes.
Engineered wood flooring glue
Apply the glue (e.g. Barlinek glue – 1K 950 single component , with a suitably elastic adhesive) with a B11 notched trowel, carefully spreading it into the substrate. Finally, the glue tooth should be formed in such a way that it is not excessively flattened. The glue should be applied on the substrate and prepared for no more than 2 rows. After gluing-down the floor boards, you have to press them to the ground, which in practice means, for example, placing the remaining packages on the floor in several places in the room – thus pressing the floor, you can be sure it will be equally glued in every place, and the glue will adhere to the entire floor substrate.
Barlinek engineered wood flooring installation
Single-component polyurethane-silane glue, combines the advantages of polyurethane and silane glues. It is intended for gluing layered floorboards, solid floorboards, mosaic, traditional, layered, industrial 16-22 mm parquet as well as exotic parquet connected by means of tongue and groove joints. The glue can be used on cement and anhydrite screeds, concrete and ground OSB. It is suitable for underfloor heating. It does not contain solvents, is flexible after bonding, but above all safe for the finished varnished or oiled floor, because glue residues can be removed without damaging the floor even after a few days. The glue should only be used indoors.
Engineered wood flooring glue-down installation – advantages
- quiet floor – the most effective way to absorb impact sounds
- possibility of laying on large areas without the need for expansion joints
- gluing-down is also recommended in the case of floor installation on underfloor heating, according to the rule “the less underneath the board the easier it is for heat to penetrate”
- glued-down floor is easier to renovate – sanding
