How to carry out construction acceptance for mixed oil painting

3. Acceptance of mixed oil painting

The type of paint used shall meet the design requirements. The color of the brushing surface shall be the same and there shall be no traces of brush marks. There shall be no peeling, brushing, anti-rusting, whitening, bottoming, falling, wrinkling, wrinkling, or uneven color. Defects, pull line inspection decoration line, color line straight, error is less than 1 mm, used to touch the paint surface is smooth, no block feel, wood adjacent hardware, glass and walls clean, no traces of oil.

4. Common oil quality problems and treatment methods

(1) Top Paint Brushing: The common quality problems of top paint painting include bottom penetration, anti-alkali, cracking, and uneven coating.

1 through the bottom: The main reason is that the grassroots improper handling and paint too thin, caused by lack of hiding power, the prevention and treatment method is to clean up the oil, rust, etc. when the grassroots treatment, the construction of the paint to adjust the consistency is appropriate, if thinned It can be solved by increasing the number of brushings.

2 Anti-alkali: Mainly because of the dampness of the base layer, the top base must be dry before it can be painted. If there is anti-alkali, it should be reworked and repaired. When the grass is dry, puttying will be done and the painting operation will be carried out.

3 cracking: it is due to putty shrinkage. The main reason is that before the construction, the putty was not completely dry and the putty was scraped again. The second time the putty was not dried, the paint was applied, causing cracking in the back layer of the putty. The construction should wait for the putty to dry again and then scrape it again. The thickness of the putty should not exceed 2 mm. Rework and repair should be scraped first cracked, and then putty scraper, putty and then painted finish.

4 The top is not smooth: The main reason is that in addition to the unsatisfactory base treatment, the paint is too thick and the thickness of the coating is also an important reason. In addition to the prevention and treatment methods, the primary treatment must be smooth and clean, and the consistency of the paint adjustment during construction should be appropriate. The paint brush should be thin every time to prevent accumulation. When repairing, leveling can be done with fine sandpaper.

(2) Mixed oil brushing on wood surface: The common quality defects of brushed oil on wood surface include falling, brushing, bleed, blistering, wrinkles, and rough coating, among which falling, brushing, wrinkles and coating The causes of rough film and its treatment methods are basically the same as that of varnishes, which can be solved by referring to the methods provided by the clean oil construction section. Focus here to solve the problem of blistering and bleeding.

1 Foaming: It is caused by the high moisture content of wood or the wood itself containing oil, especially when the big core board is directly painted and mixed with oil. Outside the poor, the construction environment is too high, the surface of the wood is dry, and the inner layer is not dry yet. During the construction, it is necessary to ensure that the wood is dry and completely removes the grease from the wood. During the operation, it is necessary to wait until the upper layer of the coating is completely dry before painting. When repairing, air bubbles should be removed and the bottom layer should be cleaned. After drying, brush 107 glue and putty putty. After the putty is dry, apply a brush to the surface.

(2) Bleeding: Mainly due to the penetration of dyestuffs in the wood, the penetration of the wood grease or the deeper color of the bottom layer than the surface layer. The method of prevention and treatment is that during construction, the color of the surface layer should be deeper than the bottom layer, and the parts with high dye and lignin content in the wood, such as thrift, must be sealed with the paint film. If bleed occurs, polish the paint before repairing, and then paint again.

5. Estimated duration of mixed oil painting

Mixed oil painting is a high-tech construction project, and it takes a lot of man-hours to work. Generally, all three rooms, two halls, and all wooden furniture paintings require about 10 days of time, of which the primary treatment is about 2 days, and the mixed oil painting is 3 times for 8 days. Around, there are process waiting times. Depending on the quality requirements of the paint, the number of wood furniture, and the drying time of the materials used, the schedule will vary. Mixed oil painting, can not work with other dusty jobs.
