The old house renovation decoration ground treatment method and matters needing attention

Floor decoration, floor tiles, and stone materials are commonly used for floor decoration. When the floor is re-decorated, different floors will have different treatment methods. Generally speaking, there are no two ways to replace or completely remove and replace the floor decoration materials. The following explains the ground treatment methods and precautions for the renovation of the old house.

floor

If the original floor is solid wood and it is kept well, it may be possible to dismantle the loose parts without reinforcement or adjustment. But generally do not consider repainting on the original floor, because when the new paint is repainted and paint brand and paint on the original floor do not match, there will be a chemical reaction, will damage the paint, serious will stain the floor Plates, causing the floor not to be used. If paint remover is used to remove the original paint and repaint it, the construction cost is relatively high. Even the cost of artificial paint and paint remover will reach more than 120 yuan per square meter, and it is difficult to maintain the original appearance of the floor. Hand brushing also makes it difficult to guarantee the quality and effectiveness of the paint.

If the original floor is a composite floor, if the service life is less than five years and there is no serious wear, you can continue to use it, but check the integrity of the floor and whether it is loose. It should be noted that if you want to make a partial repair or replacement, the colors, textures, and surface finishes of newly-purchased flooring are very different from those of floors that have been used for several years. The other is if local replacement or repair must look for professional manufacturers, do not give decoration construction team to do it.

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.

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 the renovation of the floor, it is recommended that consumers consult a professional supervisor 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.
