Solid wood flooring is the ground decoration material that has been dried and processed. Since most of the users can not distinguish their advantages and disadvantages when they buy the floor, together with the improper methods in the construction, many quality problems such as deformation and blackening of the solid wood floor occur, causing unnecessary economic losses. How to buy solid wood flooring? Solid wood flooring is divided into two types according to the depth of surface processing. One is the paint board, that is, the surface of the wooden floor has been painted, and can be used directly after installation; the other is the board, that is, the surface of the wooden floor is not painted, and must be polished and painted after laying. Can use it. The types and price positioning of solid wood flooring are divided into the following categories: rosewood, clouded wood, teak, etc. The most expensive, cherry wood, beech, maple, etc., followed by ash, beech wood and Southeast Asian miscellaneous wood. Solid wood flooring has three grades: AA grade, A grade, and B grade. The AA grade has the highest quality and the least color difference. When testing solid wood flooring, visual defects such as dead knots, insect eyes, oil eyes, tree cores, etc. shall be visually observed. The number of joints shall be less than 3, the depth and length of the crack shall not be greater than 1/5 of the thickness and length, and the slope of the diagonal lines shall be less than 10%. No corrosion point, graphic texture straight. Solid wood floors should also be further tested for their quality: smooth surface finishes, no warpage, uniform, complete, and regular processing of mouth gills, and no burrs or damages are acceptable products. Among them, the moisture content of wood must be specially tested. Floors with high water content must be deformed after installation. The floor water content in the northern area should be less than 10%, and Wuhan should be around 12%. Otherwise, it should not be used. In the purchase of solid wood flooring, should be based on their own actual situation to be determined. First of all, the wood species of the selected solid wood flooring should be determined in accordance with the requirements of the design style, such as the darkness and lightness of the color, the sparseness and denseness of the wood grain, and then be positioned on the basis of their own economic ability. After confirming the above requirements, we should carefully examine the square standard and notch splicing standard of wooden floor: Match two solid wood floor slots to slide, check whether the sliding is smooth, and whether the joint between the board and the board is smooth. In the choice of solid wood flooring, do not be good or bad on the color difference. Solid wood flooring is a natural material, even if it is a tree on the wood, its sun-facing and shady face is also a color. Chromatic aberration is an inevitable factor of natural materials, it does not affect the quality of the floor, nor does it necessarily affect the appearance. In addition, the length and width of solid wood floors should not be considered when selecting products. The long board has high requirements for material selection and large loss, so the price is high. In the construction process, it is not very easy to deform. The small plate material has high utilization rate, low price, and is not easily deformed and is economically applicable.
