Laminate flooring to see environmental protection
Look at the amount of formaldehyde released. This is the most critical issue in strengthening the floor. Under normal circumstances, the product inspection report "moisture" is relatively large, as the average consumer, it is difficult to see the problem, it is recommended that consumers look at physical goods, it is best to sell the factory's warehouse to see the new package of goods. If the place where the laminate flooring is laid smells the odor of formaldehyde, the product has generally exceeded the prescribed standard.
Visually check the appearance quality. That is, the substrate, the structure of the wood fiber can be seen from the side slot of each board, and the finer the fiber, the better. Second, we must also see if there are obvious bubbling, uneven color, cracking and scratches. Feel free to remove a pack of flooring to see if there is a significant bend.
Measure wear resistance. The degree of wear resistance does not need to be too high, 3000 rpm is enough for home use. Wear-resistant rotation is not a condition for determining high-quality flooring. Consumers can choose according to their economic strength and environment. Before purchasing or laying, consumers randomly sample a piece, sand it with sandpaper 180 times, and observe whether there is wear on the floor surface decoration layer pattern.
Look at the moisture content. Try to choose a product with a smaller water-absorption thickness.
Try to use well-known products. Should buy brands, manufacturers, site, model, specifications, grades and other packaging clearly identified products.
Multi-layer solid wood floor to see the degree of integration between layers
Look at the thickness of the surface layer. The difference in the price of flooring of the same specification depends mainly on the thickness of the surface wood. The thickness of the common multi-layer solid wood floor covering on the market is about 15 mm, and there are also 20 mm, but it is not as thick as possible. Consumers should try to choose products with a surface thickness of 12 mm.
Observe the appearance of the floor. Whether the paint film is full and even, there are no signs of pin particles, indentations, and planing marks on the surface. Whether the surface of the material has defects such as decay, dead knot, wormhole, or crack, etc., whether the flaws and grooves around the surface are complete or not. Randomly extract a few pieces of floorboards to be assembled on the ground to see if there are obvious heads (gap) at the joints between the boards and whether the boards are flat.
Solid wood floor materials
Tree species selection. Choose wood flooring to choose wood species that have relatively stable wood properties and high hardness. It is best to choose imported dried products, and then choose color and wood grain.
Material and size options. Many people think that the harder the wood, the better. In reality, the harder the wood, although it has better wear resistance, it is relatively poor in dimensional stability. Choose narrow and short in size as possible, although the laying effect is not as good as a long and wide floor, but the smaller the size, the smaller the deformation may be.
Observe the appearance quality. Observe whether there are bugs on the surface of the floor (if not more than 1mm), cracking, decay, mildew, dead knots (but for small joints, color difference should not be too demanding, this is the natural properties of wood) and other defects. For the paint floor, it is also necessary to see whether the paint film on the surface of the lacquer board is even, plump, bright and clean, and whether there is any paint leakage, bubbling, perforation or pitting.
Look at the moisture content. Try to choose flooring that is close to the local temperature and humidity.
