1. Look at the thickness: the surface thickness of solid wood composite flooring determines its service life. The thicker the surface plate, the longer the wear resistance. The surface thickness of solid wood composite flooring in Europe is generally required to be more than 4 mm.
2. Look at the material: the solid wood composite floor is divided into three layers: surface, core and bottom. The surface layer is a wear-resistant layer, and varieties with hard texture and beautiful texture should be selected. The core layer and the bottom layer are balanced buffer layers, and the varieties with soft texture and good elasticity should be selected, but the most crucial point is that the varieties of the core layer and the bottom layer should be consistent, otherwise it is difficult to ensure the structural stability of the floor.
3. Look at the processing accuracy: The biggest advantage of solid wood composite flooring is its high processing accuracy. Therefore, when choosing solid wood composite flooring, we must carefully observe whether the splicing of the flooring is tight, and there should be no obvious height difference between two adjacent boards.
4. Weighing: Of course, I weigh it myself. A good floor should not be too light or too heavy. The weight of the floor is too light, mostly because the material of the selected base material is relatively soft, so the strength will be relatively poor, while the heavy floor is easy to deform and crack.
5. Look at the flatness of the floor: the high-quality multi-layer solid wood floor has strict requirements on material selection, process control and factory inspection, and the edge and surface of the finished floor are flat and straight. Inferior floors are much rougher. Generally, when you observe the edges and surfaces along the length of the floor with the naked eye, you can see obvious bumps or warps.
6. Look at the appearance: the high-quality floor paint surface is full, smooth, rich and natural, the paint film is transparent, and the physical properties of the appearance are unobstructed. The paint surface of inferior floor is dry and obscure, and there are many exposed paints, blisters, pinholes, ripples and particles. The transparency of paint film is poor, the texture of surface board is vague, and the appearance of wood is obscure.

Professional methods to distinguish the quality of composite flooring
1. Look at the paint film: High-grade solid wood composite flooring should adopt advanced UV matt paint, which is UV-cured and has excellent wear resistance. Generally, it does not need to be waxed and maintained for household use, and it does not need to be painted for more than ten years. Another key index is sub-gloss, and the brightness of the floor should first consider softness and elegance, which is not irritating to vision.
2. Look at the glue used: As we all know, solid wood composite flooring is made of three or more layers of wood by gluing and hot pressing, and urea-formaldehyde resin is generally used as the adhesive, so there is bound to be a certain amount of formaldehyde. In the production process, high-grade environmentally-friendly solid wood composite flooring must use glue with low formaldehyde content to ensure the environmental protection index of the product.
3. Detailed treatment: See whether the back plate and its surroundings are sealed. High-quality floors generally paint the back plate and its surroundings, thus effectively reducing water vapor absorption and preventing warping and deformation. Most of the back and surrounding base materials of inferior floors are exposed, and there are many defects such as burrs, indentations and glue penetration, which are easy to cause deformation and warping.
4, look at the buckle type: high-quality multi-layer solid wood floors generally use locks, which have the advantages of no need for sizing, convenient installation, tighter stitching and difficult separation in use. Most of the inferior floors are made of cheap buttons, which makes the floor easy to loosen and detach, and it needs to be installed with glue, which is not environmentally friendly and is not easy to disassemble and reuse.
