The solid wood flooring currently on the market mainly consists of teak, eucalyptus, ash, birch and medium and high-grade imported wood.
Solid wood flooring generally has two types, one is a long strip wood floor, the length is generally between 45cm ~ 90cm, the thickness is more than 1.6cm, the width is more than 6cm, it is not directly bonded to the ground, the keel must be played below Or a large core plate as a layer; the other is a short ultra-thin type, which is directly bonded to the ground, and its quality requirements are mainly high dryness and low sleepiness.
Some details of the solid wood floor laying process need to be noted: First, the size of the keel raft should not be too thick, otherwise it will affect the space utilization, the general thickness can be 4 × 1.5 ~ 2cm; Second, can not use cement nails, but should be used After the electric shovel is hit, use wooden wedges and screws to nail into the ground about 2.5cm. 3. After the keel raft is installed, it will not move left and right. Therefore, it is no longer necessary to fix it with cement mortar, so that the floor will not be caused by insufficient curing time. Arch or tile-like deformation; Fourth, for home installation, foam pad, 9mm plywood can be used, if used, should use 12cm ~ 18cm plywood, and should be divided into 4 ~ 6 pieces, well keel The surface of the board is nailed. Since the quality of solid wood flooring sold on the market is different, the most obvious ones are different lengths. Therefore, it is recommended to purchase the solid wood flooring as much as possible without exceeding 60cm in length and 7.5cm in width. Although long, it is easy to assemble, but the long one is easy to be skewed, warped, and easily deformed, while the short solid wood floor is not easy to warp. Moreover, the gap between the boards and the fight are well grasped.
The standard for the installation of solid wood flooring is: the paving is firm, no empty drum, cracking, skewing, warping, overflowing glue, stains, etc.; the seam between the board and the board should be straight and the seams should be tight, and the joint width should be about 1mm. The skirting board is closely connected to the floor, and the wall surface should be close to the wall without gaps. Another point to note is that the number of solid wood flooring should be slightly increased compared to the actual laying area. Generally, the room of 20 square meters is increased by 1 square meter for consumption. In addition, whoever buys the floor will be laid, so that it can be guaranteed for one year. In case of quality problems, it is easier to solve.
How to identify composite wood
Solid wood composite wood flooring is a new type of flooring between solid wood flooring and laminate flooring. It has the natural texture, texture and elasticity of solid wood flooring, and has the advantages of strengthening the floor's resistance to deformation and easy cleaning. The wood-based composite floor is made of wood and sliced ​​into thin slices, criss-crossed, and multi-layered and combined to make the wood fibers intertwined to maintain stable properties.
To choose solid wood composite flooring, we must first select the appearance quality, not only depends on whether the color, texture and paint quality of the surface wood meet the grade standard. Generally, there should be no decay, dead knots, joint holes, wormholes, skinned resin capsules, cracks or Wood defects such as loose seams, wood texture and color perception are harmonious, paint finish should be uniform, no bubbles, small white spots, etc., the surface should not have obvious stains and damage. When selecting the appearance, you should also look at the tongue and the groove around the floor for defects. It should be complete.
Secondly, it is necessary to select whether the size of the product is the same as the size, width and thickness of the product you purchased, and then check whether the dimensional tolerance of the product is consistent with the purchased grade. Method of measurement: It is possible to take a plurality of floors in the same package and assemble them by themselves. After assembly, observe whether the joints of the rafts and grooves are tight. At the same time, the floor after splicing can be touched by hand, if there is a high and low protrusion The phenomenon indicates that the product is unqualified. After touching the hand, pick up two pieces of assembled multi-layer solid wood floor and shake it in your hand to see if it is loose. In short, there can be no looseness.
Finally, picking intrinsic quality is a key indicator of composite wood flooring. It can be seen from the water swell thickness expansion rate that its waterproof and moisture-proof performance is as low as possible, preferably less than 2%, and secondly less than 5%. The pyrotechnics are burned on the surface, and if there are no traces, the fire protection coefficient is high. Formaldehyde content is an indicator that cannot be ignored. According to national regulations, the formaldehyde content per 100 grams of floor should not exceed 9 mg.
In addition, the experts also pointed out that consumers should carefully inquire about the difference between different grades of composite flooring when purchasing laminate flooring, and remember the code of the selected grades of products, and check whether the code on the packaging matches.
The key to choosing laminate flooring
Reinforced composite wood flooring is generally made up of four layers, namely wear layer, decorative layer, substrate layer and bottom layer.
The bottom layer, that is, the moisture-proof layer, is generally made of polyester material, which can block the moisture and moisture from the ground, thereby protecting the floor from the moisture of the ground and balancing with the above layers.
