1. Floor sample board specifications

From the qualitative point of view of board stability, the smaller the floor size, the better the resistance to deformation. Therefore, it is necessary to select a shorter and narrower solid wood floor to minimize the bending, twisting, ladling, shrinkage, arch, and other phenomena of the solid wood floor. Floor experts believe that the short is better than the long; the narrow is better than the wide, and it is cheap and good quality. However, the wide board is popular in the market, which is more beautiful and generous than the narrow plate, with a relaxed texture and complete pattern. However, the qualified wide plate must be selected strictly and the quality acceptance should be carried out. Generally, there should be an anti-deformation groove on the back of the wide floor, and the groove depth should be one-third of the floor thickness. If used for floor heating, it should be thin rather than thick, generally 8-12mm thick.

2. Floor sample board moisture content

The moisture content of the wood floor is very important. The moisture content of the floor must be the same as the local equilibrium moisture content. Buy floor must measure moisture content, if do not have a moisture content tester, do not buy its board. The method of balanced moisture content measurement is very simple. In the exhibition hall, the moisture content of the purchased varieties is measured first, and then the moisture content of the wood floor is detected out of the box. If the moisture content difference between the two is only + 1% - 2%, it is a qualified product.

3. Floor sample board material

Observe with eyes whether the floor is the same kind of material, whether the board surface has cracking, decay, peeling, dead joint, wormhole, blue change, and other material defects. Generally, there is no need to be too strict with a color difference, knot, and texture, which is the natural property of wood. It is the color difference, rich in natural texture, showing the natural color of a solid wood floor, is the fashion pursued by the current international family decoration.

4. Machining accuracy

Generally, about 10 pieces of the wooden floor can be assembled by hand after unpacking, and the processing quality precision, smoothness, smoothness, tenon groove matching, installation gap, anti denaturing groove, and so on are closely connected. Observe the bite of tongue and groove, assembly gap, the height difference between adjacent plates. If the seam is strictly closed, there is no obvious height difference.

5. Floor after-sale

There are many wood flooring manufacturers in the market, and the quality is uneven. It is recommended to choose a good brand of wood flooring. These brand manufacturers will provide perfect after-sales service and have a certain warranty period. You can save a lot of heart.
