Installation of parquet boards: main rules

It’s important to understand a few guidelines and technical details in order to glue parquet boards to a concrete floor in a high-quality and elegant manner.

• Careful preparation of the concrete screed for work – you can install parquet boards at least 28 days after pouring the floor, on a flat base without defects (except perhaps the smallest ones, since they will be covered by a layer of glue and insulating materials).
• It is advisable to lay layers of hydro/vapor barrier between the parquet and concrete. Under certain conditions, an additional heat-insulating layer is often laid.
• In installation, you can use bitumen mastic, which acts as waterproofing and primer at the same time.
• The glue must be correctly selected, taking into account the characteristics of the surface, wood and the size of the lamellas, other important conditions.

• Screed humidity should be around 3.5-4%. It is advisable to measure with a device, as this is an important parameter for laying parquet.
• Mandatory level control – the base must be pre-leveled and during the work the master must constantly check the lamellas to eliminate the appearance of local differences, which then create a creak and contribute to deformation, destruction of the coating.
• Priming – a special composition is applied to the concrete, which largely affects the strength and reliability of fastening the parquet to the glue. It is advisable to select a primer in accordance with the adhesive composition.

The correct glue choice and application technique can make all the difference when installing parquet over a concrete screed. We’ll go over the best glue types for this task in this guide, along with simple instructions you can use to glue parquet boards yourself. This will guarantee a solid, long-lasting bond and a polished appearance.

What adhesive mixtures are used

A range of adhesive compositions can be used to glue the parquet. Today’s market offers a vast array of them; the substances vary in terms of types, manufacturers, volumes, costs, and specifications.

– epoxy composition that is resistant to significant temperature fluctuations. binds any kind of material.

– two-component parquet composition that can be covered with any kind of surface.

Single-component

These adhesives are simple to use, come pre-made, and don’t need to be diluted or prepared.

Solvent-based adhesives have the drawbacks of being poisonous and smelling strongly. When working, personal protective equipment is worn. Because the solvents in this glue are flammable, using it close to a fire source is prohibited.

Two-component

These kinds of compositions are elastic, strong, fast-drying, and adaptable in terms of the coating and base materials. Solvents are not present in the product composition; instead, polymerization is the result of combining the hardener and polymer base. These adhesives are all fairly pricey, but they do not shrink and provide a long floor life.

When selecting a two-component adhesive, consider the following factors: dosage, elasticity, moisture resistance, and usage time (which is typically specified on the can). Generally, you want to mix the entire can at once; if not, you might forget to calculate the ingredients and the glue won’t set. It is therefore preferable to glue all of the lamellas again if the composition has not hardened after three to four hours.

Other formulations

Various kinds of adhesives can be used when working with parquet glued to a concrete base. The most well-known ones are mentioned above; additional substances that are available and frequently used are listed below.

– based on polyurethane modified with silane; elastic, long-lasting; unrestricted in terms of base and coating material usage; devoid of solvents and water.

How to properly attach a board to a screed with glue

For the parquet installation to be completed correctly and the coating to function well and last for a long time, proper installation is required. First, when laying on deck, it’s best to accurately calculate the material for the floor with a margin of at least three to five percent.

Without unpacking, the material is delivered to the location at least two days in advance, preferably more, to give the tree time to acclimate. The adhesive is chosen based on the qualities and recommendations listed above.

A hammer, hacksaw, hammer drill, tape measure, limiting wedges, a regular notched trowel (or better yet, several), and a tamping block are the tools needed to lay parquet with glue.

Materials required: parquet, nails, adhesive sealant, plywood (if you intend to create a backing), and parquet glue.

• Adhesive composition is applied with a spatula to a clean, even, dry concrete screed, plywood sheets are mounted on top, which are additionally fastened with screws at 32 points. You need to move from the center to the exit, the sheets are mounted staggered, all voids are filled with sealant, 5 mm gaps are left near the walls.
• The first row of parquet is glued using limiting wedges with 10 mm gaps from the wall. Glue is applied to the plywood and the ends of the parquet lamellas, the boards are additionally fastened together with nails. To achieve maximum adhesion, the boards must be pressed firmly to the floor, remove excess glue.
• Each subsequent row is shifted by half a board relative to the previous one. The evenness of the flooring is checked with a level.
• After installation is complete, the floor is not touched for the period indicated on the glue packaging. Only then can the base be sanded, varnished or treated with oil, etc..

Method of installation without plywood: features

Boards and parquet can be fastened straight to concrete. Significant time, money, and effort savings are realized as a result. Hardboard was placed on top of bitumen-backed plywood for ceilings, and floors were constructed on wooden joists during the days before strong adhesives.

Piece parquet is simple to install on concrete that is free of cracks and spaces. Once completed, the floor is steady and level. After the boards are glued to the concrete base, the parquet is sanded manually or using a special machine, the cracks are sealed with a sealant, and the surface is sanded once more. After priming, the completed surface is varnished or coated with oil.

The varnish coating is regarded as more important since it shields the floor from moisture and mechanical damage and adds to its durability and beauty.

When installing without plywood, solid boards may not always have the best dimensions and geometry, so you will need to use nails to secure and tighten them.

You can completely change your space with a stunning, long-lasting floor by adhering parquet boards to a concrete screed. Selecting the proper parquet glue is essential for a durable finish. To guarantee a solid bond, make sure the adhesive you choose is compatible with both concrete and parquet flooring.

Make sure the concrete surface is dry, level, and thoroughly cleaned before starting. The key to preventing any more flooring problems is to take this step. Before laying the parquet, apply the adhesive evenly, paying attention to the manufacturer’s instructions and working in small sections to keep the adhesive from drying out.

To guarantee that the parquet boards adhere correctly, place them carefully and press down firmly. When the glue is fully set, don’t walk on the floor and let it cure as directed. You can improve the appearance and feel of your space with a professional finish by following these easy steps.
