Renovation of old houses is like modifying a work that has already taken shape. It takes more time to work than a new house – but as long as the old house can be decorated with craftsmanship, the ingenious use of decoration paint can also rejuvenate the old house. Now the experts introduce the readers to the knowledge about the purchase of old house decoration paints.
First, carefully design, find the renovation of the project before the renovation of the old house, the decoration company also has to carry out the overall design, involving the treatment of the facade wall, ceiling and other places, it is best to send professionals to conduct on-site exploration of the house. Such as wall, floor, ceiling, etc., whether there are obvious cracks, whether it is flat, whether there is falling off and sanding. If the above problems exist, the base layer should be repaired. When repairing, it is best to use environmentally friendly interior wall putty. The product is environmentally friendly, non-toxic and non-irritating. No matter the old wall, it has very strong adhesion. Its strong permeability is like playing on the wall. Innumerable nails are added, so that the original cracked or powdered hollow wall is polished and smooth, smooth and smooth, and convenient for the construction of latex paint.
Second, the focus on the doors and windows to renovate the doors and windows in the old house should be one of the key points of the transformation. The degree of photochemicalization of doors and windows is divided into several cases. First, if the wooden doors and windows are peeled and deformed, the characteristics of the wood itself change, and the redo must be removed. If the material is compact, the surface paint film is intact, and it can be used during the second construction. Use a decorative panel to make use of it. Second, steel doors and windows, security windows, if the surface paint film peeling off, the main body is rusted or cracked, must also take the corresponding measures to transform.
Generally speaking, due to the long time, it is difficult to express the natural texture of wood by using varnish, so it is necessary to use solid wood lacquer at this time, so that it can not only cover the old lacquer surface, but also give different according to the new decoration style. The color achieves the magical effect of decaying.
Third, the renovation of the old house wall, the top surface of the old house should focus on the decorative materials. Among them, the wall coating is the most typical. The wall top layer of the old house will have different degrees of cracking, chalking and mildew after years of use. If these problems are not solved properly, the paint of the back brush will also appear color. Uneven effects of unevenness, rough surface and peeling. This requires an advanced pretreatment of the base layer such as the top surface of the wall.
In particular, with the development of coatings over the past few years, different performances and different types of coatings can be selected by consumers. If the owner is on the first floor, they can recommend environmentally friendly mildew interior latex paint, such as children at home. Easy to scrub interior wall paint.
SIC
Emery, also known as Silicon Carbide (SiC), is produced by high-temperature smelting of resistance furnaces using quartz sand, petroleum coke (or coal coke), and sawdust (need to add salt when green silicon carbide is produced). Silicon carbide also has a rare mineral, Moissanite, in nature. Silicon carbide is also called Carbon silica. Among the non-oxide high-tech refractory raw materials such as C, N, B, etc., silicon carbide is the most widely used and the most economical one, and it can be called gold grit or refractory sand. At present, China's industrial production of silicon carbide is divided into two types of Black Silicon Carbide and green silicon carbide, are hexagonal crystals, the specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320kg/mm2.
Silicon carbide has two common basic varieties of black silicon carbide and green silicon carbide, both of which are α-SiC. 1 Black silicon carbide contains about 95% of SiC. Its toughness is higher than that of green silicon carbide. It is mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. 2 Green silicon carbide contains more than 97% SiC, self-sharpening, mostly used for processing hard alloys, titanium alloys and optical glass, also used for honing cylinder liners and grinding high-speed steel cutters. In addition, there is cubic silicon carbide, which is a yellow-green crystal made by a special process, used for the production of abrasives for bearing superfinishing, surface roughness can be processed from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 micron.
