Real stone paint construction is simple, easy to dry and time-saving, easy construction and so on. Then, what is the practice of real stone painting on the exterior wall ? Many people may not be aware of it. Don't worry, let's take a look at the relevant knowledge of the real stone paint practice of the outer wall .
What is real stone paint
Real stone paint is a coating that resembles marble and granite. It is mainly made of natural stone powders of various colors and applied to the effect of imitation stone on the external walls of buildings. Therefore, it is also called liquid stone. The building with real stone lacquer decoration has a natural and natural color, giving people an elegant, harmonious and dignified sense of beauty. It is suitable for indoor and outdoor decoration of various types of buildings. Especially on the curved buildings, it is vivid and lifelike, with a natural return effect. Real stone paint has fireproof, waterproof, acid and alkali resistance, and pollution resistance. Non-toxic, odorless, strong adhesion, never fade, etc., can effectively prevent the external environment from corroding the building and prolong the life of the building. Because the real stone paint has good adhesion and freeze-thaw resistance, it is suitable for Use in cold areas.
Real stone paint advantages
Advantage I: Highly decorative, high-viscosity coating that mimics natural stone, marble and granite
Natural color, texture of natural stone, a variety of line design, can provide a variety of three-dimensional shape of the pattern structure, can visually highlight the elegance of the entire building and the dignity of the beauty, is the best alternative drywall stone.
Advantage two: wide application
It can be used for various base surfaces such as cement brick walls, foams, plasters, aluminum plates, and glass, and can be painted arbitrarily with the shape of the building.
Advantage three: water-based environmental protection
Real stone paint uses water-based emulsion, non-toxic environmental protection, in line with people's requirements for environmental protection.
Four advantages: good stain resistance
90% of the dirt is difficult to adhere to. After the rain has washed away, it is as bright as new and easier to clean by hand.
Advantage 5: long service life
High quality real stone paint can last up to 15 years.
Advantage six: economic benefits
Good quality real stone paint, a square meter of the market price of about 70-150 yuan (including construction), dry hanging stone with installation costs at least 400 yuan / square meter above, in contrast, real stone paint occupies absolute cost-effective advantage.
Advantage seven: no security risks
The use of stone dry hanging on the external walls will impose an additional burden of thousands of tons, seriously endangering life and property. Real stone paint materials 4-5kg/m2, only 1/30 of the stone weight, strong adhesion, will not fall off like the stone as a whole, effectively protect safety.

Introduction to the practice of real stone paint on the outside wall
First, construction preparation:
1, the main material: 1.1 material: exterior stone paint, primer, topcoat, putty, cement, 801 glue. 1.2 Material Quality Requirements: The paint must have a paint performance test report and a paint poison content test report.
2, the main equipment: air compressor, electric spray gun, hand-held electric mixer, simple leveler, line package, hair rollers, brushes, knife, argon arc welding machine, electric drill and so on.
Second, the operating conditions:
1. The doors and windows are protected as required, and the gap around the hole is blocked.
2. The original wall surface is completed and meets the design requirements. It is accepted according to the standard of the plastering surface, meets the conditions for spraying the slurry, completes the repair of the equipment hole, and smooths the hole around with cement mortar. All the walls need to be air-dried. . It is required that the surface of the grass-roots level be smooth and dry (the surface of the cement mortar should be maintained for more than 15 days), and there should be no floating ash, asphalt and other stains, and PH<10, moisture content <10%.
3. Double racks or movable baskets must comply with national safety regulations. 4. All finished doors and windows should be protected in advance.
Third, the operating process:
1. Process flow: wall surface treatment, acceptance → original wall surface treatment → elastic wire, grid, adhesive stripe → brush sealer primer → paste dividing line → use special hair roller to brush → spray stone paint → brush surface Paint → local repair.
2. Grassroots treatment: after the acceptance of the grass-roots level, do a partial repair. Requirements: smooth, smooth, no oil, no holes, no trachoma, flat, straight.
3. Brush closed primer: The primer is rolled on the base layer, requiring uniform brushing and five leaks.
4. Paste dividing lines: In order to ensure uniform brushing effect, it is recommended to use plastic strips for dividing lines.
5. Special spray guns for spraying: Requirements: Use a special spray gun for spraying, should ensure that the pattern is uniform, no section, no connection. After spraying, let it dry naturally for about 6 hours to ensure that the paint is applied on the dry surface.
6. Brush finish: requirements: uniform, no brushing phenomenon, color lines to clear lines, straight, straight.
7. Check the quality of construction and repair other parts after local pollution.
Fourth, quality standards:
1. Assurance items: The variety, color and quality of the products must meet the design requirements and be submitted to the construction in time.
2. The surface of the finished product is required to be free from obvious defects, leaks, bottoms, and falling.
V. Finished product protection:
1. During the construction, protect the doors, windows and the construction site.
2. The construction sequence from bottom to top is strictly prohibited to avoid acceptance pollution.
3. Do not damage the wall coating when you remove the shelf or drop the basket.
4. Finished finished products are prohibited from being stomped to prevent contamination.
Six, should pay attention to the quality issues:
1. Connection phenomenon: The main reason is due to the overlapping of the coating and the unevenness of the finish. Therefore, in the construction process, the following measures should be taken to avoid the connection phenomenon. 1.1 The interface should be thrown on the dividing line. 1.2 The best construction is to survive once and not to be repaired. This requires layer acceptance and strict quality control so as to avoid the phenomenon of catch-up.
2. Hollowing and cracking phenomenon: The main reason is that the bottom layer plastering is not caused by the construction of the technical requirements. Therefore, before the construction, the inspection and acceptance of the wall surface should be carried out according to the standard of the inspection of the cement mortar plastering surface. Otherwise, the surface layer Paint cannot be applied.
3. The phenomenon of lice in the surface layer: The main reason: In the construction of cast-in-place concrete, due to the stencils caused by the stencil joints, the plastering process must be modified to reach the plaster before the surface layer is applied. The standard to avoid this phenomenon after surface construction.
VII. Finished product protection:
1. Clean the surrounding environment before painting to prevent dust from flying and affect the quality of brushing.
2. Before the construction, the door and the easy-to-paint wall should be shielded and protected to prevent cross-border pollution.
3. Do not step on the finished part when applying. Dismantling and turning the shelves is the soil layer where the salt spinning collisions and pollution have ended.
4. After the paint finishes dry, protect the mouth, corner, etc. in time to prevent collision damage.
Editor's summary: The above is the introduction of the practice of exterior wall real stone paint coating classroom: construction team how to control the actual use of the external walls of the relevant introduction of the situation, hoping to help meet the needs of friends!
