Five tips for choosing multi-layer solid wood flooring

Multi story solid wood flooring, also known as solid wood composite flooring, is a headache for many homeowners when it comes to decoration. During the decoration process, it is not only necessary to engage in a battle of wits and courage with the decoration company, but also to understand the procurement and selection of various decoration materials. Especially in the area of wooden flooring, today Kagao Flooring's editor will come to help you relieve stress. With just five tips, we can help you choose solid wood composite flooring, making it easy for you to choose materials.

1. Look at the appearance of solid wood composite flooring
Solid wood composite flooring is generally divided into three categories: excellent, first-class, and qualified. Appearance quality is an important basis for grading. When purchasing, the first thing to consider is whether the color and texture of the surface wood are clear. Generally, the surface should not have wood defects such as decay, knots, insect holes, cracks, or loose joints. The texture and color of the wood should be harmonious. It is also necessary to check whether the tongue and groove around the floor are flat.
2. Clarify the types of solid wood composite flooring
There are two types of solid wood composite flooring, one is a three-layer solid wood flooring, which is composed of three layers of wooden boards: surface board, core board, and back board. Another type of multi-layer solid wood flooring is composed of seven or nine layers, which has better stability than three-layer solid wood flooring. When purchasing, you should choose between three-layer or multi-layer solid wood composite flooring according to your own needs. If it is a floor for underfloor heating, it is necessary to choose multi-layer solid wood flooring.
3. Observing the structure of solid wood composite flooring
Consumers can see the layered structure of veneer through the four sided tenon joints of multi-layer solid wood flooring. Traditional multi-layer solid wood flooring substrates use odd numbered layers of preforms, usually consisting of seven or nine layers. When making a purchase, you may want to pick up the floor and see how many structural layers it has.
4. Clarify the formaldehyde content of solid wood composite flooring
Multi layered solid wood flooring is composed of multiple wooden veneers assembled and bonded together, and the quality and environmental performance of the floor adhesive are crucial. Once the glue used is poor or even of poor quality, it can seriously exceed the formaldehyde standard and affect the user's physical health. The current mandatory highest standard for floor environmental protection in our country is E1 level, which means that the average formaldehyde release is less than 1.5mg\/L. So it's best to buy E1 grade flooring when making a purchase in order to use it with confidence.
5. Splicing solid wood composite flooring for testing
Take 5 or more pieces of flooring and place them on a glass countertop or flat ground for assembly. After assembly, pat the mortise and tenon tightly with your hand to observe whether the joint is tight, and then touch it with your hand to feel if it is flat. Pick up the assembled multi-layer solid wood composite floor and shake it in your hand to see if it is loose. If there are any prominent tactile or loosening phenomena, it indicates that the product is unqualified.
