Paint is an important part of interior decorating, and it is prone to some thorny problems that make people helpless. In fact, as long as the real cause of the problem is identified, it is not difficult to have satisfactory results for the remedy of the disease. The following is a solution to the problem that paint is easy to produce, so that you can be more comfortable in the interior decoration. The peeling of the paint may be due to the fact that the surface is too smooth. If the original paint is lacquer or powder (with untreated sizing paint), the new paint will not stick to the surface. Or it may be wood decay or metal rust, or peeling off due to poor paint quality. A small area of ​​paint is peeling off. It can be sanded with fine sandpaper, then putty put on it, brushed with a primer and repainted. Exfoliation over a large area must scrape all the paint off and repaint it. First, the paint blisters will be punctured, if there is water, which means that the paint layer underneath or behind the infiltration of moisture, the sun a sun, the water evaporated into vapor, it will paint up into a bubble. At this point, the blistering paint is removed with a hot air gun, the wood is allowed to dry naturally, then the primer is applied, and finally the entire repair surface is repainted. If there is no water in the bubble, it may be cracked wood grain, there is a small amount of air, the sun through the sun, the air expands, the paint bulge. Faced with this situation, first scrape off the blistering paint, then use a resin filler to fill the cracks, repaint it, or use no filler. After the paint is peeled off, apply a microporous paint directly. Most cracks appear to be removed with a chemical paint remover or hot air gun and then repainted. If the fracture range is not large, then sanding blocks or wet or dry sandpaper can be used to dilute the broken paint. After the surface has been smoothed, apply putty, apply a primer, and repaint it. Paint paint flowing once is too thick, it will cause runny. The paint can not be dry yet. Brush it with a brush. If the paint has started to dry, dry it. Use a fine sandpaper to smooth the paint, clean the surface, clean it with a damp cloth, and re-apply it. Outer paint, be careful not to brush too thick. There are many causes of smear on the surface of a stained paint. For example, the moisture in the latex paint dissolves the substance on the wall and the paint surface is rusted. The wall surface that is rubbed with the steel wool will cause rust spots, and the dark pipe inside the wall will appear with stains. In order to prevent stains, a layer of primer containing aluminum powder may be applied first. If stains are present, remove the emulsion paint at the stains first, brush the primer layer containing aluminum powder, and then re-paint. The problem of moldy discoloration occurs most often on wet paint surfaces. When water vapor condenses on glass or metal surfaces, brownish-black stains are often generated. At this point can be used fungicides, according to the instructions of the instructions to deal with moldy parts, to be killed after the mold, the surface clean and then re-paint. The reason for the loss of luster is that no primer has been applied, or that the primer and the inner layer of paint have not been dried and there is a light paint directly on the paint. As a result, the light paint is absorbed by the wood and loses luster. The poor quality of glossy paint is also a reason. Grind the old paint with wet or dry sandpaper, brush the dust, wipe the surface with a clean, damp cloth, and dry the paint again. It is important to pay attention to the fact that paint is applied in very low temperatures and the paint film may lose its luster after it has dried. The wrinkling of the film is usually caused by the second pass of the first pass of the paint. At this time, the solvent in the lower layer paint will affect the upper layer of the film to make it wrinkle. In this case, the wrinkled paint film can be removed by chemical amalgamation or heating and repainted. Remember, we must wait until the first time after the paint is dry before we can go on the second pass. Rough paint The newly painted surface is rough, usually the paint brush used is not clean or contaminated by the surrounding environment. It is also possible that the paint is mixed with patent leather, that it is not precipitated and filtered before use, that the filter paper or the paint is stained with dust. In order to prevent these problems from occurring, clean paint brushes and paint buckets must be used. Before using the old paint, be sure to filter it with paint filter paper or clean nylon stockings. In addition, the painted surface should be covered with a cover or cardboard when the paint is dry to prevent dusting. If the paint is rough, after it has dried, use a wet or dry sandpaper to polish it and clean it, then repaint it. Pay special attention to the paint brush must be clean. The appearance of dark spots on the surface of the painted wood may be caused by the fact that the wood section was not sealed before being painted, and the sun was exposed to the sun, the wood section was heated, and the resin leaked from the wood section. At this point scraper can be used to scrape off the paint, and then polished with fine sandpaper to expose the knots, seal the knot with a knotted paint, and wait until dry, and then re-paint. The paint does not dry well in the room or the temperature is too low, the paint will dry slowly. It is possible to open all doors and windows to promote ventilation, or put a heater indoors to increase room temperature. If it still fails to solve the problem, it may be that the painted surface is greasy. This can be removed with a chemical paint remover or a heating method, thoroughly rubbing the surface, and then repainting. The lacquer sticks to the bug as much as possible. When the paint is not dry, remove the bug, and then use a brush to dip a little oil to gently repair the surface. If the paint has started to dry, wait for the paint film to harden completely and wipe off the bug. This will not make the surface messy with wooden boards and plywood. Plywood is made up of three or more layers of odd-numbered wood veneers that are glued perpendicularly to each other in the direction of the fibers. Commonly known as plywood and plywood. There are many species of plywood produced. At present, ash, beech, birch, masson pine and some imported logs are mainly used. Plywood has the characteristics of uniform material, small moisture absorption, large size, no warpage, beautiful surface pattern, and strong decorative properties. Walls and ceilings are generally made of 5mm thick plywood. If there are sound absorption requirements, they can be processed into perforated plywood with different apertures, different hole pitches, and different patterns according to the pattern. 2, fiberboard. According to the bulk density, it can be divided into hard fiberboard, semi-hard fiberboard and soft fiberboard. Hard fiberboard is mainly used for the panel of the ceiling and partition wall. The board surface is drilled to form various patterns. The surface is sprayed with various paints, and the decorative effect is better. Hard fiberboard sound absorption, waterproof performance, durable, screen, easy construction. 3, wood wool board, wood board, particle board. Will be wood, wood chips, shavings, etc., after drying and adding adhesive after mixing, is divided into low density board, medium density board, high density board, particle board standard thickness is 19mm, there are 9mm, 15mm thickness, Can do partition board, ceiling and so on. 4, thin wood plywood. The ash, willow, wood, birch, etc. are cut into thin slices of 0.1-0.5mm thickness, and plywood is used as the base material. The pattern is beautiful and the decoration is good. Plastic plate 1, PVC plastic decorative plate. With a smooth surface, colorful, waterproof, corrosion resistance and other characteristics. 2, calcium plastic decorative board. Also known as calcium plastic foam decorative acoustic board, divided into general board and non-flammable board two. This kind of decorative board is made of polyethylene resin added with inorganic fillers. It has a variety of concave and convex patterns or perforation patterns on the surface. It has the characteristics of light weight, heat preservation, sound absorption, heat insulation, insect resistance, water resistance, and small deformation, and it is beautiful in appearance. The construction is convenient, but its durability and aging resistance are slightly inferior. 3, polyethylene foam decorative sound-absorbing panels. With heat insulation, sound insulation, fire protection, light weight and other characteristics. Gypsum board It uses gypsum as the main material, adding fibers, adhesives, and modifiers, and mixing, pressing, and drying. With fire protection, sound insulation, heat insulation, light weight, high strength, low shrinkage and other characteristics and good stability, no aging, pest control, available nails, saws, planing, sticking and other methods of construction. Widely used in ceilings, partitions, interior walls, and plywood. Gypsum board is divided into ordinary paper gypsum board, fiber gypsum board, gypsum board 3 kinds. Inorganic fiber board is divided into mineral wool decorative sound-absorbing board, glass wool decorative sound-absorbing board, cement asbestos sound-absorbing board, etc., with sound absorption, fire prevention, heat insulation, heat preservation, easy construction and so on. Metal decorative plate 1, color coated steel plate. It is made of hot-rolled steel plate and galvanized steel plate coated with 0.4-0.5mm soft or semi-rigid polyvinyl chloride plastic film. It has heat and corrosion resistance and can be used as wallboard. 2, aluminum alloy decorative plate. It is also called aluminum alloy pressure plate or ceiling buckle plate. It is made of aluminum and aluminum alloy as raw materials. It is processed by roll pressing and cold pressing into various sections of metal plate. It has light weight, high strength, good rigidity, corrosion resistance and long-lasting. Durable and other excellent performance. After the surface of the board has been anodized or painted and sprayed, a variety of colors required for decoration can be formed. 3, mirror stainless steel decorative panel. It is made of special polished stainless steel sheet. Its characteristics are as bright as a mirror surface, reflectivity, deformation rate and high-level mirror almost the same, and fire-resistant, moisture-resistant, no deformation, no broken, easy installation, but should be hard material scratches. Previous article: Geothermal floor - the warmth and comfort of the soles Of the current renovation, composite wood flooring is very popular with everyone. It has a wooden texture and color, gives a more natural, warm and healthy feeling, and it is relatively easy to clean, install, and relatively cheap compared with solid wood flooring, so it has been very popular recently. There are a lot of brands on the market, and all of them are made from Sweden, Germany, and other foreign brands. They look very similar in appearance. Some ads are very powerful, some are very luxurious, some are very low, and the package is only about 90 yuan. Some of them are original, Hong Kong is open and the like. Consumers will find it dazzling and have no choice. How should we choose? To identify the quality of laminate flooring, it is generally necessary to identify from the following aspects: 1. Whether the surface texture is clear and whether the deep layer is even; 2. If the opening is neat, put a few pieces together, and the seam between them should be very It feels small when you touch it. As shown on the left, the surface on the floor should be very smooth. Third, the aging test: Put a few pieces of different brands of composite wood flooring into the water and cook for a few hours, the pros and cons of it immediately emerged, the poor quality of the body is broken bones, good quality will only have a small deformation. However, in addition to the quality of the floor itself, installation and maintenance are also important. When installing, it is best to do waterproofing, especially kitchen and toilet entrances and entrances, balcony entrances. Frequently exposed parts of water, such as kitchen and toilet doors, should be covered with a small piece of carpet to absorb unexpected moisture. As regards maintenance, it is mainly to prevent the surface of the wooden floor from being scratched because it is irreparable. Related topic articles:
