Coating process: wood paint coating construction process

Key tips: 1 Classification of Waterborne Wood Coatings The color paint of water-based wood coatings mainly includes solid color paint and transparent color paint Solid color paint is similar to the mixed paint of solvent type paint, which contains a lot of coloring pigments and fillers, with high covering power It can cover solid wood grain on wood and present the true color of paint Transparent color paint changes the color of wood itself, does not cover the wood grain, but makes the wood texture more prominent and personalized The two kinds of color paints are usually applied by spraying and brushing, especially in home decoration and simple industrial production The water-based coating is the combination of temperature and 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: 1

changes the color of wood itself, does not cover the wood grain, but makes the wood texture more prominent and personalized The two kinds of color paints are usually applied by spraying and brushing, especially in home decoration and simple industrial production Waterborne coating is one of the most sensitive coatings to temperature and humidity Because many properties are different from solvent coating, and wood fiber structure determines wood's hydrophilicity and high sensitivity to water, the coating process and experience of solvent coating cannot be applied in construction 2 The preparation and coating before coating shall be carried out after the completion of carpentry work No matter how narrow and limited the space environment is, the construction site must be clean and free of dust, fly ash and disorderly objects, so as to avoid affecting the construction quality The best condition of coating environment is room temperature (about 23 ℃), and the temperature is constant, the humidity is below 70%, with soft ventilation Under this condition, it can ensure the rapid evaporation of water and reduce the phenomenon of grain formation and long hair thorn The coating effect will be affected if the ambient temperature is lower than 15 ℃ or higher than 30 ℃ The coating should be carried out in a sunny day Before the spraying construction, the parts that do not need to be painted must be covered tightly to avoid the paint mist The soft brush shall be used for brushing It is required that the hair shall not be shed, soft and strong in water absorption Before use, the bristles which are not firmly fixed shall be smoothed, cleaned with clear water, and then used after the water is dried It must be noted that before the brush is dipped in the paint, it must be moistened with water in advance, but there shall be no water drop, otherwise the paint brush will be dried and scrapped quickly, or the paint retained at the root of the brush will become dry and dross, which will affect the coating effect Before using the paint, it is necessary to mix it well, especially for the color paint and the paint with extinction powder Don't mix the paint by concussion In order to ensure the painting quality, the water-based coating must be filtered before use The varnish shall be filtered with a filter screen of more than 300 mesh, the paint shall be filtered with a filter screen of more than 200 mesh, or the paper core filter of corresponding mesh shall be used 3 The solid color paint of the coating process can be directly applied on the wood surface, or the color paint can be applied after puttying and priming The painting method of transparent paint is to paint (wipe) the wood surface before applying varnish or transparent paint Compared with the pre coloring (rubbing) method, it is not easy to get a uniform coloring film when transparent dye is dissolved in the water-based paint and applied directly to the wood surface Because the uneven surface and small gap of the wood surface cause the uneven thickness of the film, the color of the thick film is deep, and the color of the thin part is light, so that the uniform effect of the whole paint surface is very poor See Fig 1 for painting construction flow chart of color paint Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire
