Buy solid wood flooring: check substrate defects

Today, more and more people like to use wooden flooring in the decoration. However, many consumers believe that the more expensive the solid wood flooring, the heavier the solid wood flooring. Chen Xudong, deputy director of the National Key Laboratory of Wood Species Identification and Timber Quarantine of Zhangjiagang Inspection and Quarantine Bureau of Jiangsu Province, believes that this is a misunderstanding. The correct choice of solid wood flooring should be considered from the following four aspects.

Observing the floor precision After removing the wooden floor from the box, take out about 10 pieces and assemble them by hand. Observe the bite of the floor, the assembly gap and the height difference between the adjacent floors.

Check the substrate defects to observe the floor section, see if the plate texture is confusing, and check for defects such as dead knots, joints, cracks, decay, and bacteria. Because the solid wood flooring is natural wood products. Objectively there is a phenomenon of chromatic aberration and unevenness, and there is no need to care too much about chromatic aberration.

The national standard for measuring moisture content stipulates that the moisture content of wood flooring is 8% to 13%. Due to regional differences, the moisture content of the floor in the northern region is 12%, and the moisture content in the southern region should be controlled within 14%. At the time of purchase, first measure the moisture content of the selected wooden floor in the exhibition hall, and then measure the moisture content of the same type of unopened wood and the same size wooden floor. If the difference is ±2%, it can be considered qualified.

At present, the name of the tree species on the market is very chaotic, and some manufacturers are promoting the wood. The wood crowns are not in line with the well-known names of wood science, such as: rosewood, gold, and jade sandalwood; What's more, in the low-end high-grade wood, consumers must not be confused by the name, to clarify the material, so as not to be fooled.
