>>> This site friend floor installation diagram As second-hand housing continues to heat up, second-hand housing renovation has become a hot spot, and renovations such as renovation of the floor and renovation of stone materials have also started. Because the renovation of the floor is cheap, many second-hand homeowners plan to completely renovate the old floor. However, according to experts, only solid wood flooring, solid wood flooring and bamboo flooring with a surface thickness of 4 mm can be refurbished. In addition, local refurbishment can also cause new and old differences between floors, so consumers cannot blindly refurbish the floor. Floor surface thickness requirements Floor retreading is to restore the old floor as new by sanding, scraping, painting, and waxing the floor surface. Compared with repurchasing the floor, the old floor is adapted to the indoor environment, with better stability and much lower renovation costs. However, according to experts, not all floors can be refurbished. There is a layer of aluminum oxide wear-resistant layer on the surface of the laminate floor. The refurbishment of the floor will damage the wear-resistant layer and cause the aging of the floor to increase. Therefore, the laminate flooring cannot be refurbished. Only solid wood flooring, engineered wood flooring and bamboo flooring with a surface thickness of 4 mm can be refurbished. Because the surface of the floor after grinding several times, will be polished off 1-2 mm, if the floor surface is too thin, it will polish the middle layer, thus affecting the floor life. Pay attention to monitoring the quality of renovation At present, there are very few specialized floor retreaders, and most of the businesses involved in this business are Procter & Gamble. In order to ensure the quality of floor renovation, it is recommended that consumers request professional supervision personnel to supervise the construction. Floor renovation is divided into grinding, scraping, coloring, painting, waxing and polishing five steps. When sanding, the sander should use 40-, 80-, and 120-grit sandpaper in order (the larger the mesh, the smaller the sandpaper particles, the less noticeable the scratches are after grinding). Sand three times, then puttying the floor, and then The floor is painted or shaded. Because the texture of the solid wood surface is natural, it cannot change the color, but can only adjust the depth of the floor color. Before retreading, all items in the house should be removed to ensure that the house is clean and dusty when painted. The floor generally requires brush primer and two coats of paint. If the surface of the polished floor is flawed, it is necessary to brush the primer several times depending on the situation. Once the paint is completely dry, it can be brushed again. Therefore, the renovation of the floor usually takes 4 days. Partial refurbishment is not good The overall refurbishment of the floor of a room is better. It can basically achieve the effect of a new floor, but the partial renovation will result in the difference between the floor and the floor. The longer the service life of the floor, the more obvious the difference between the old and the new. Damaged, mildewed and deformed floors may not be refurbished. Floor mildew generally goes deep inside the floor. The surface of the polished floor is still subject to moldy spots; floor deformation and damage cannot be remedied by sanding. If only a small part of the floor is damaged, mildewed, and deformed, it can be replaced with a floor of the same color. If there is no floor with the same color, you can choose a floor with similar colors and color and distress it to minimize the chromatic aberration. If most of the floors have been damaged or have become mildewed or deformed, it is recommended to purchase them again. Floor Paint Interior Decoration Room Cleaning Company
