Construction process of home mounted wood paint: blank plate → grinding → base material sealing (puttying) → grinding → brushing primer (the first time) → grinding → brushing primer (the second to the third time) → full grinding → brushing finish (the first time) → grinding → brushing finish (the second time) 1 The blank treatment can effectively remove the stain, wood wool and wood thorn on the board, so that the board surface is clean and smooth 2 The plate sealing function can effectively seal the plate to prevent the plate from being polluted At the same time, prevent excessive moisture absorption and dissipation of the board, slow down the deformation of the board, enhance the adhesion between the paint film and the board, save the amount of primer, prevent the paint film from sinking, enhance the hardness of the paint film, and slow down the external volatilization of harmful substances such as formaldehyde in the board 3 For hole filling treatment, apply putty and fill wooden holes to reduce the amount of paint and improve the smoothness of paint film 4 The primer shall be used to fill the wooden holes and increase the thickness of the paint film 5 The sanding treatment makes the whole paint film surface flat and smooth, forming a ground glass shape, and enhancing the adhesion between layers 6 The environmental cleaning function reduces the particles on the surface of the paint film, so that the paint film surface has a better coating effect 7 The finishing paint construction plays the role of decoration and protection to ensure the final film effect Precautions for home decoration wood paint Construction: 1 Before use, it shall be carried out in strict accordance with the proportion in the operation manual, and polyester paint shall be diluted to the construction viscosity by adding the matching diluent according to the construction requirements 2 When the multi-component of polyester paint is mixed, it shall be fully stirred and kept for about 15 minutes, so as to facilitate the early maturing reaction between components and eliminate the bubbles generated during mixing 3 When spraying or brushing, ensure that the base material is dry When the substrate is wet, it is easy to cause peeling, blistering and falling off of the paint film At the same time, the thickness of the paint film shall be strictly controlled If the wet paint film is too thick, it will dry for a long time, and it is easy to absorb water in the air to make the paint film white and blister 4 The solvent with low boiling point still has the problem of staying in the film, so it is necessary to pay attention to the control of interlayer interval time during construction Too short interlayer interval is very easy to cause the film bubble, wrinkle, whitening and other diseases 5 During the construction, it is necessary to wear a mask to keep the indoor ventilation, so as to avoid the harmful substances volatilized from the ground dust and solvent from inhaling into the human body The flash point of solvent based wood paint is low Open fire is strictly prohibited at the construction site to prevent fire 6 Avoid construction in rainy season and high air humidity In particular, spraying in high humidity weather is easy to cause white coating; furniture painted in rainy weather can not be stacked to avoid mildew and blackening on the surface of furniture 7 Avoid the simultaneous construction of polyester coating and latex coating It is better to brush the latex coating after the polyester coating is completely dry Because the polyester coating contains free TDI, the volatiles in the painting process will cause the latex coating to turn yellow 8 At present, there are many kinds of new plates, remind painters to make small samples during construction, that is, small area construction, and then large area construction under the condition of no problem, so as to ensure the construction quality to meet the standard requirements Construction acceptance method of home mounted wood paint: 1 Clear wood grain on the paint: This is for wood products with transparent effect of wood paint After the transparent wooden furniture is painted, the grain of the wood is not covered, and the natural material feeling of the wood can be displayed For the owner who requires to present the wood grain effect, when checking the wood paint surface, it is necessary to check whether the grain on the wood surface is clear, whether the brown eye is scraped flat, and whether some other defects on the wood are well covered 2 The color of the paint surface is uniform without color difference: This is for the wood products with color paint effect After the wood furniture with color paint effect is painted, the grain of wood is covered, presenting the color of color paint When the wood paint with color paint effect is accepted, it is necessary to check whether the paint surface is evenly brushed and whether there is a difference in color depth The paint surface is required to be free of brush marks 3 The paint surface shall be smooth, smooth, saturated and plump: during the acceptance, the paint surface can be touched lightly by hand to see whether it is smooth and whether the thickness is uniform High quality wood paint should be smooth and even, without rough and particle, with uniform thickness At the same time, check whether the paint saturation and fullness are good Check the glossiness of the paint surface, and carefully observe whether the reflection is even 4 The paint surface shall be free of defects such as whiteness, granulation, pinhole and crack: due to improper construction of wood paint, various problems may occur on the paint surface For example, there are particles of size on the surface of the paint film; the color is whiter than before, in the form of white fog; there are pinholes of the size of needles; cracks appear on the surface, etc During the acceptance, special attention should be paid to the existence of these serious problems 5 The side and bottom are not painted in place: during the acceptance of wood paint, many people may pay attention to the painting effect and quality of wood paint on the surface of furniture, but often neglect the places where the side, back, inside and bottom of furniture are easily not painted in place Therefore, we must pay attention to this point during the acceptance If the bottom surface can not be seen, we can use the reflection of the mirror to observe 6 Check whether the decoration line and color separation line are straight: for furniture with mixed color paint, when accepting the wood paint, pay attention to check whether the decoration line and color separation line are straight The color separation at the junction of qualified wood paint and two-color paint is even and straight, showing a vertical line, with almost no deviation The color separation line between the two colors is zigzag, extremely unsightly and unqualified During the inspection, the wire can be used for measurement, and the error shall not be greater than 1mm 7 Check whether the hardware adjacent to the wood is clean: if the hardware, glass, wall and ground adjacent to the wood are not well protected during the construction of wood paint, these objects and parts are easy to be stained with paint Therefore, during the acceptance, in addition to the inspection of the wood itself, it is also necessary to check whether adjacent objects and parts of the wood are clean and stained with paint Home of coatings focuses on coatings, paint coatings, coating technology, news and information of fire retardant coatings, coatings, coating technology, decoration knowledge and decoration renderings of fire retardant coatings“
