First, the process characteristics:
1, real stone paint construction is simple, time-saving, and construction machines and tools are easy to clean;
2. Real stone paint has the advantages of fireproof, waterproof, alkali-resistant, pollution-resistant, non-toxic, tasteless, strong adhesion and never leg color;
3. Real stone paint has good adhesion and freeze-thaw performance;
4. Using real stone paint can prolong the life of buildings.
Second, the scope of application:
This technology is suitable for the decoration of indoor and outdoor walls of various buildings, especially for the decoration of various curved buildings.
Third, the construction preparation:
1, material preparation:
Prepare topcoat, intermediate coat and primer of real stone paint according to design requirements, and configure various decorative topcoats according to design requirements.
2. Preparation of construction machines and tools:
Prepare a corresponding number of tools, such as air compressor, spray gun, hose, brush, roller, etc. According to the division of engineering quantity and construction operation section.
3, construction conditions:
3. 1 The foundation should be firm and not empty;
3.2 The base should be dry, and the moisture content should be less than10%;
3.3 The construction temperature should be higher than 5℃;
3.4 No construction is allowed in rainy and windy days.
Fourth, the construction process:
Five, construction technical measures:
1. Basic treatment: the plastered wall shall be smooth and firm, meeting the requirements of intermediate plastering. Plastering wall should be dry, and then blow be bored with child. After the putty is blown, there shall be no cracks, holes, depressions and other defects in the finish.
2. Brush sealing primer: In order to improve the adhesion of real stone paint, the sealing primer should be brushed on the foundation surface once. The sealing primer can be coated by roller or spray gun. The coating must be uniform and brush leakage is not allowed.
3. Spray imitation stone paint: Before spraying, mix the real stone paint evenly, put it in a special spray gun, and then spray it. The spraying pressure should be controlled at 0.4-0.8Mpa, and the spraying sequence should be from top to bottom and from left to right, and spraying should not be missed. When spraying real stone paint, a thin layer should be sprayed quickly, and then slowly, steadily and evenly. The effect of spraying is related to the size of the nozzle and the distance between the nozzle and the wall. When the diameter of the nozzle is Ф 6-Ф 9, and the distance between the nozzle and the wall is properly adjusted, the ejected light spot is larger and the convexity and concavity are stronger. When the diameter of the nozzle is Ф 3-Ф 6, and the distance between the nozzle and the wall is appropriately reduced, the sprayed spots are small and the decorative surface is relatively flat. However, the distance between the nozzle and the wall should be controlled at about 0.4-0.8M, neither too big nor too small.
4. Polishing: The real stone paint should be solidified after spraying. After 24 hours, when the real stone paint is completely dried, it should be properly polished and the decorative dust should be cleaned.
5. Topcoat: After the topcoat is cleaned, the topcoat shall be sprayed or sprayed. If spraying is used, the spraying pressure should be controlled at 0.3-0.4Mpa.
Six, quality acceptance criteria and quality measures:
1. guarantee project: the variety, grade, model, color and performance of real stone paint (including sealing primer, intermediate paint and top coat) used in the project shall meet the requirements of design and sample selection, and the product certificate shall be available.
2. Basic project: excellent.
3, acceptance criteria:
3. 1 No peeling or peeling is allowed on the facing;
3.2 The facing shall not have alkali returning and color biting;
3.3 There should be no missing coating and spots on the surface;
3.4 The density of decorative points should be uniform, and the spray points of the front and squint should be uniform within the range of 1 m, and contiguous points are not allowed.
3.5 The finish color should be uniform;
3.6 When painting, ensure the cleanliness of surrounding doors and windows, glass and lamps.
4, quality control:
4. 1 Materials must have product certificate and test report when they enter the site;
4.2 Construction personnel shall make technical disclosure before construction;
4.3 During construction, it should be noted that the grass-roots units must be cleaned up, and there should be no oil pollution, dust and empty drum.
4.4 In the process of spraying, attention should be paid to the uniformity of spraying points, and there should be no leakage and sand dropping.
4.5 In the process of construction, there should be part-time or full-time quality inspectors to supervise and inspect each working procedure and strictly control it.
Seven, safety precautions:
1, construction personnel must carry out safety education before entering the site.
2. Before construction, the construction personnel shall make a written safety disclosure.
3. The construction operators shall not laugh and play in the process of construction, and shall conduct civilized construction.
4. Power tools for construction shall not be disassembled at will. If tools are found to be damaged, they should be handed over to specialized personnel for maintenance.
5. Unqualified power tools, electrical boxes, etc. Shall not be used in construction.
