Coating technology: introduction of wood paint construction technology

Core tip: there are two main processes of wood paint One is varnish process As the name implies, this kind of wood paint refers to painting transparent or opaque paint on the wood surface, so as to achieve a beautiful and natural effect; the other is oil mixing process, which is mainly manifested in the choice of colors of the materials used, mainly in the opaque saturation and high color The names of the two kinds of wood paint are different, and the specific construction technology is also very different The construction process of varnish process is more complex, which is divided into 12 steps, as follows: 1 Coloring or tinting oil; 2 Apply varnish to protect primer, which is required in this step Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: there are two main processes of wood paint One is varnish process As the name implies, this kind of wood paint refers to painting transparent or opaque paint on the wood surface, so as to achieve a beautiful and natural effect The other is oil mixing process, which is mainly reflected in the choice of colors of the materials used, mainly in the opaque saturation and high color The names of the two kinds of wood paint are different, and the specific construction technology is also very different The construction process of varnish technology is more complex, which is divided into 12 steps, as follows: 1 Coloring or color mixing oil; 2 Brush varnish to protect the primer In this step, it should be noted that if it is to keep the original color to brush varnish, the surface must be cleaned and the first protective primer shall be applied immediately after the material is purchased The primer is generally the top coat, and the varnish surface must be treated before the wall paint is applied; 3 Clean the dust and dirt on the wood surface; 4 Polish the board surface or wood line surface with sandpaper; 5 Brush the first paint; 6 Mix the prepared color powder, cooked rubber powder and Shuangfei powder into putty after drying out, and cover up such as nail holes and tree scars to make them the same as the original color; 7 Polish the rough part of the color powder with fine sandpaper after drying out, the first time is very important, and make sure to polish the surface; 8 Brush one side of paint below; 9 After drying out, polish the fine sandpaper; 10 Brush the paint again; 11 Wet the surface of the wood with a wet cloth first, and then polish the surface with sandpaper, which is called water grinding; 12 Finally, brush the paint again Generally speaking, in the varnish process, when the last paint is added, it needs to be painted for about 4-8 times in total to have a better effect The more times the surface paint is, the better, but generally not more than 10 times Different from varnish process, oil mixing process is simpler, which is divided into 9 steps, mainly as follows: 1 First clean the dust and dirt on the surface of the wood; 2 Mix the surface of the wood with pig blood ash and double fly powder; 3 Polish it with sandpaper after it is completely dry; 4 Brush the first coat; 5 Mend the defects; 6 Polish it with sandpaper after it is completely dry; 7 Brush the second coat; 8 Polish it with sandpaper after it is completely dry; 9 Apply the third coat of paint In the oil mixing process, the process is relatively simple, and the painting is mainly two to three times The above is the difference between varnish process and oil mixing process Of course, no matter what kind of wood paint process is adopted, it is necessary to clean the dust, oil and other impurities on the wood surface Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
