Construction steps of fulette real stone paint
Real stone paint is also called imitation stone paint or stone paint, which belongs to the scope of synthetic resin emulsion sand wall architectural coatings. However, the aggregate gradation used in coatings is more reasonable than that of past colored sand coatings, and the color is richer, the shape is more realistic, the construction method is more delicate, and the application scope is more extensive. Real stone paint is a kind of paint with strong artistic quality in architectural coatings.
I. construction tools:
1. Scaffolds: scaffolds must be 30-40 cm away from the painted wall, and there should be no horizontal water bar against the wall, and there should be no foot, hand and eye on the wall. It is advisable to use hanging rails and bridges. During the construction of bamboo scaffold, proper construction distance shall be set aside.
2. The air compressor with power above 5kW, sufficient air volume and pressure of 0.5-1.0mpa has three air pipes, which can meet the simultaneous construction of more than three people and can automatically control the pressure.
3. Spray gun: the upper pot spray gun has a capacity of 500ml and a diameter of more than 1.3mm. The capacity should not be too large and the operation is inconvenient. If the diameter is small, the construction speed is slow and large area construction is not suitable.
4. Nozzles of various diameters: 4mm, 5mm, 6mm, 8mm, etc. the smaller the diameter is, the smoother the spraying will be. The larger the diameter is, the larger the spot will be, and the stronger the concave convex feeling will be.
5. A set of airless spray gun.
6. Rubber pipe: oxygen pipe, 8mm in diameter.
7. Brush, roller and blade.
8. Shelter tools: plastic cloth, fiberboard, pushpin, tape.
Construction technology of real stone paint:
① for the acceptance of the painted base, the hollowing and cracks on the wall surface shall be reworked by the painted base. Clean the floating sand, sand particles and other sundries on the wall, and maintain the wall for one to two weeks, with pH < 10
② mark and mark according to the design requirements, mark with black line, and paste with tape. In order to ensure the horizontal and vertical, the master setting die shall be used as the marking line. In addition, the non brush part of the wall shall be sealed with tape and film to prevent pollution.
③ apply elastic putty. This product is a two-component product. Pour two components of the package into the container, fully mix them into paste paste without particles and precipitates for use. Use a spatula to directly apply the above paste paste on the base surface. The dosage is controlled within 2 kg / ㎡. The putty is completely dry (about 24 hours), and enter the next process.
④ one coat of alkali resistant primer shall be applied to the roller, and the roller shall be evenly applied with the same direction. The joints of the upper and lower coating layers shall be free of trace and the color shall be the same.
⑤ spray the real stone paint in two times, and the air pressure is generally 0.6-0.8mpa. When spraying, the objects not to be sprayed shall be pasted with newspaper or completely isolated with tape. The dosage is about 5kg / m2.
⑥ remove the adhesive tape immediately after spraying. Be careful when removing the adhesive tape, which will not affect the cutting angle of the coating film. Remove the adhesive tape as far as possible and do not pull it forward.
⑦ after the real stone paint is hardened, grind the sharp corner particles on the surface of the real stone paint to about 30-50%, which can increase aesthetic feeling, reduce sharpness and avoid dust accumulation.
⑧ after the real stone paint is completely hardened, roll or spray the top coat.
⑨ comprehensively inspect the painted wall, correct the problems found in time, clean and clean the site.
Construction process of real stone paint with different colors:
1. The white and light colored real stone paint construction wall shall be scraped with white cement first, which shall be flat without obvious batch mark; or the colored liquid primer shall be directly applied, and then the middle layer and surface layer shall be sprayed as required;
2. The construction primer of dark stone paint shall be sprayed according to the regulations. In the middle layer of construction, only one thin layer shall be sprayed, the thickness shall be controlled at 1-2mm, and then the top coat shall be applied.
