Engineered board as an alternative to natural solid wood and parquet continues to gain popularity among owners of houses and apartments. In this article, our site of advice will tell you in what ways an engineered board can be laid on a prepared base, be it a screed or plywood.
Recall that an engineering board consists of layers. The top one is a natural wood veneer with a thickness of 3 to 6 millimeters. Then there is a simple birch plywood, on the lowest layer of which there are stiffening ribs to ensure the strength of the flooring. This option for arranging the finishing of the floor does not practically differ from the massive board, about which the portal wrote in detail. But engineering board costs less, which attracts homeowners.
The first method of laying engineering is on glue
Such adhesives are made on the basis of polyurethane compounds, which makes the coating resistant to moisture ingress. The glue can be used both in the case of laying the engineered board on chipboards or thick plywood, or directly on the concrete mix..
Important! Manufacturers categorically do not recommend laying the engineering board on a cable underfloor heating, a cork backing and a gypsum self-leveling floor..
The second method of laying an engineered board is combined
In this case, an adhesive is also used, but in addition, each board is attached with special screws. Sometimes hairpins are used instead. In this case, it is important to correctly drive the fasteners into the grooves of the boards at an angle of at least 30 degrees, maximum 45 degrees. The combined installation method is used on plywood or chipboard. It is very reliable, because the board is attached in two ways at once. This method is not much more expensive than conventional glue, but it takes significantly more time..
The third way of laying an engineered board is floating
In this case, the board is not connected in any way with the base and the substrate, it can be easily dismantled and replaced. The engineering plank must have standard Click locks to use this installation method. The disadvantage of the method is that it requires very careful preparation of the base, which must be perfectly flat. Of the advantages – speed, savings on self-tapping screws and adhesive composition. In order for the flooring to be reliable and dense, you need to strictly adhere to the technology.
The fourth method of laying an engineering board is a thorn-groove
This technology is called “keyed”. Of course, the board must have factory-made tenon and groove connections. This method is used in houses made of poorly dried timber and log cabins that shrink, as well as in regions with a humid climate. For the reliability of the connections, a mallet is used, it is impossible to tightly connect the boards manually.
Important! In any case, experts advise to pre-spread the lamellas in order to minimize the need for cuts and create a clear pattern..
