Wood floor buying tips:
Use the nose to smell if there is any smell: high-quality laminate flooring generally has the taste of a relatively heavy wood board. Low-priced inferior flooring is the opposite. If you smell it with your nose, you will have a strange smell and smoked nose, which will make you feel uncomfortable. Using this product will have a negative impact on your health.
Test the water absorption with water: the density of the high-quality wood floor substrate is very high, it is not easy to absorb water and damp. The simplest test method: pour the water on the substrate of the floor, it will not be absorbed into it, like Water beads float on the substrate as they flow. The low-priced inferior floor is absorbed by the water, and the clear water immediately disappears. In the life use, it quickly expands and foams.
Look at the surface with the eye: observe whether the density of the substrate is high density, medium density or low density; whether the color is normal white, whether the wood surface particles are fine and normal, and the wood surface particles are as fine as the gray surface, which is the washed substrate. The structure and density are far from the density of the material of Jiangxi Fuzhou Daya substrate; whether the wood grain is realistic, the good quality floor is usually imported wood grain paper from the source sea, the grain is clear and beautiful, it looks very warm. The middle and low grade floors are generally made by local small factories. The color is black, the wood grain paper is not clear, and the grain is fuzzy.
Test whether the cracks are flattened: the floor with high substrate density, no matter how long it takes from the workshop to the warehouse, it will not swell, and there will be no geometric height difference. The installation interface is smooth and smooth, and it looks like the whole board. Come out is the floor that is put together.
