How to repaint an old table?

Not all furniture is suitable for painting. The surface of panel furniture is often bonded with a layer of melamine board which is difficult to peel off, and the surface is painted, which has poor adhesion. Compared with the duke of mount deer, solid wood furniture is more suitable for repainting. \x0d\ Tip: In terms of paint, we should also choose products with the same performance as the original paint on the furniture surface, so as to prevent the chemical reaction between the old and new paints and wrinkle the furniture surface. In addition, if water-based wood paint is applied, the wood itself is easy to absorb water, leading to instability. If the problem is serious, there will be slight bulging deformation and oily paint will be more stable. \x0d\ Painting technology of old furniture \x0d\ Painting technology of old furniture is more troublesome than new wood products. There are generally three kinds of paint renovation of old wood furniture: primary color renovation, color enhancement renovation and color change renovation. In addition, you can stick wood grain paper and stick melamine plastic veneer for renovation. Different construction methods should be adopted according to different situations. \x0d\ (1) Paint old white blank furniture: Some white blank furniture has been used for a long time. Although there is no paint, the surface is covered with oil. In this case, as long as the stains are removed by sandpaper polishing and the oil stains are scrubbed by gasoline, the construction can be carried out according to the wood paint process. \x0d\ Some wood products are dry and have not been painted, but they are painted with tung oil. In this case, as long as tung oil is completely dry, scrubbed and smoothed with sandpaper, it can be constructed according to the wood finishing process. \x0d\ (2) Renovation of primary colors: the wood has been painted in ready mixed paint, but the color is not good and needs to be repainted, and the renovation color is the same as the primary colors. There are also two ways to deal with this situation. One is that you don't need a primer, just scrub the oil on the paint film with soapy water or gasoline, and you can repaint it. The other is that all the old paint should be removed before it is completed. When removing the old paint, tie one end of the stick with old cloth or yarn end, dip it in caustic soda solution or sodium hydroxide solution, and use 1~2 times to clean all the old paint surfaces. When the old paint peels off, the solution and the old paint can be quickly washed with clear water, and then dried with a clean cloth. If there are a few places where the old paint has not been removed, you can scrape it off with a glass sheet, then wipe it clean with a dry cloth, and then repaint it with new primary color paint or other colored paints and varnishes. \x0d\ Preparation method of caustic soda solution: take 0.5 kg of quick-drying lime, 0.25 kg of soda ash and 3 kg of clean water. First, clear water is poured into a clean wooden bucket or iron bucket, and then lime is immersed in clear water. Dry lime expands and heats up when it meets water, making the water boil and turn into lime slurry. At this time, you can put a certain proportion of soda ash into the lime slurry, and then mix them evenly with a wooden stick to use. \x0d\ Preparation method of sodium hydroxide solution: industrial sodium hydroxide 0. 1 kg, 60~80? C warm water 0.5 kg. Put sodium hydroxide into an iron drum, then pour warm water into it to become a sodium hydroxide solution, which can be used. When using, keep a certain temperature, and do not let the sodium hydroxide solution cool. \x0d\ In use, since both caustic soda solution and sodium hydroxide solution are corrosive, be careful not to splash on your body during preparation and use, so as not to burn clothes and skin. \x0d\ (3) Color enhancement and renovation: Old wooden furniture will become obsolete after being used for a long time, which will affect the appearance and need color enhancement and renovation. The method is to add color on the basis of the original paint color and apply clear water. The process is similar to the renovation of primary colors. \x0d\ (4) Color-changing renovation: When the wooden furniture is deformed due to thermal expansion and contraction in use, please ask the carpenter to repair it. Refurbished old furniture, with different wood, color and age, can only be changed into mixed colors. The technological process is as follows: degreasing; Scraping oily putty in batches; Sandpaper grinding; Color of paint oil; Cover the lamp. \x0d\ After the renovation of the new house, furniture has become the top priority, but the appearance of the original old furniture is incompatible with the new home, so the renovation of cabinets has been put on the agenda, saving a lot of money for the renovation of my home, and it is low-carbon and environmentally friendly, which can be described as killing two birds with one stone! \x0d\ Tools: Paint remover, wool brush, painting, shovel gloves \x0d\ Buy the paint remover home first. Spray the paint remover evenly on the counter for a few tens of seconds, \x0d\ then you can easily remove the skin with a shovel. \x0d\ Further polishing is needed after shoveling. After the paint is removed, it should be polished before scraping. Here is the scraping process \x0d\ Finally, the bookcase should be left standing for one night after scraping, and then polished and scraped after it is completely dry tomorrow. We used super super sticky powder king, poured it out and mixed it with people, and it dried in less than a minute. So scrape the ash quickly, only one point at a time. \x0d\ The last step is painting. When the ash is dry, start painting. \x0d\ originally intended to paint white, but because the old paint kept returning to the bottom in the process of leveling, the white paint also kept returning to the bottom, and the white was dyed pink. So, be sure to find a paint deep enough to cover the pink! ! On second thought, we chose blue! Why not choose China Resources polyester paint? Because it is high, it is a transformation of old things. It is not cost-effective to use at least materials made in 600 yuan to paint Huarun paint. Finally, I chose ready mixed paint and Shuang Hu brands. Paint is very cheap, 40 yuan, 5 kg a barrel. Thanks to the captain, he helped us buy dark blue everywhere, but we didn't buy any. We had to buy another color paste, a bottle of color paste 10 yuan. Blended with the medium blue painted in Shuanghu Lake, and finally became this color. I feel quite like the Mediterranean style blue! Ok, let's March from the pastoral fresh wind to the Mediterranean mixed wind! This is the color paste I bought. All the bottles went to Shuanghu ready mixed paint, which is close to medium blue, and finally it became this color! \x0d\ Precautions \x0d\ When painting, be careful not to pull quickly, but to move slowly, so as to ensure that each area is sprayed with enough paint remover. If you pull it fast, there will be less paint sprayed on the surface, which will not corrode the paint on the surface and will evaporate quickly.
