Paint the old generation's real stone paint experience summary!

With the improvement of construction technology, urban tall buildings are no longer unusual, today and you share a lifetime of paint of the old generation summed up the real stone paint experience:
to do a good external wall real stone paint effect first step is to the grass-roots treatment and testing, testing is mainly divided into five steps, if these five steps testing are qualified then we can make qualified external wall real stone paint project.
1, strength: low grass strength will affect the adhesion of the coating. Qualified grass-roots should not drop powder, no sand, no empty drum, layering, cracking and stripping phenomenon,

.
2, flatness: the unevenness of the grass roots will affect the final decorative effect of real stone paint. There are four main aspects of flatness inspection: surface flat, yin and yang angle vertical, facade vertical, yin and yang angle square.
3, dryness: the grass moisture comes from mixed cement, moisture will bring alkaline substances to the surface to damage the coating. The base must be thoroughly dried before painting.
4, acidity and alkalinity: how much alkaline base will affect the bonding of the coating, but also cause the coating color change, peeling, whitening, flowering and other quality accidents. The primary pH value should be less than 10.
5, cleaning degree: remove the surface of the grass pulp, dust, oil, etc. , so that the surface is conducive to the bonding of the coating.
The most important thing is that the real stone paint also need to pay great attention to the construction, in the continuous practice summed up the following ten experiences:
1, because the real stone paint itself is heavier and the amount of larger, the general use is the use of large packaging specifications, in long-distance transport or shelved for too long, precipitation will occur, the opening barrel construction should be the best electric drill mixer mixing uniform, before the factory has adjusted the construction viscosity, do not recommend water dilution viscosity, indeed, thick water.
2, it is recommended to use hanging basket spray real stone paint, scaffolding spray will leave scaffolding joints, do not remove scaffolding can not be seen, after removal is more obvious.
3, temperature: usually in 5 degrees C above 35 degrees C below the temperature conditions of construction, humidity: suitable for construction of air humidity of 60%-70%, rainy days can not be constructed;
4, air compressor air pressure to reach more than 8kg, the actual amount of coating per square about 3.5KG to 4.5KG, more intense concave shape real stone paint will be used 5 to 6KG, so the real stone paint coating rate will be due to the product itself particle size, product construction modeling, roughness of the base surface and differences, before construction should be based on the site test coating rate.
5, on the sand loss problem when spraying: regardless of any spray will have loss occurred, the sand loss phenomenon in spraying should be based on the viscosity of construction products, construction air pressure, construction personnel techniques, etc. to determine, it is recommended to do product construction testing before the start of the project.
6, about the phenomenon of spraying flowers: real stone paint hair flowers are more common, the phenomenon of hair flowers is not sprayed uniformly, especially in dark paint, spray thick place and spray thin place color is not consistent, spraying is recommended thin spray many times, multiple molding can avoid hair flowers, recommended to use the same color primer.
7, about chroma: the product arrived at the scene first small area spray test real stone paint color, real stone paint color in line with the standard model can be large-scale construction, because real stone paint is basically the use of natural color sand raw material configuration, so there will be a slight color difference between batches, which is normal phenomenon, it is recommended that the same batch of materials used in the construction of the same group of people to build on the same wall. The whole wall should be top-down, one breath into one go, to avoid intermittent construction caused by the old and new colors. Plane effects and hair effects produce sensory differences, noting that certain colors differ in backlight and positive light, direct sunlight, and refractive conditions.
repair color difference: after the construction of a wall as far as possible to leave a few barrels of the same batch of products in order to repair the defective wall during the project sweep phase, to avoid the color difference caused by the sweeping tail repair phenomenon. If there are two batches of real stone paint on the same wall, it is best to press 1:1 at the joint two batches to stir well to evenly construct excessive chroma, construction a distance after the construction of the second batch.
8, whitening: whitening has 2 cases, one is the concrete wall re-alkali phenomenon, fingers will touch the white powder. Second, there is no rolling cover glossy paint when there is no such phenomenon, after rolling paint appears white, like fog on top, this is because the surface of the real stone paint is rough, rolling coating glossy paint did not roll evenly, resulting in the surface paint piled up in the groove will appear this phenomenon, the best use of spray construction, real stone paint construction after 48 hours immediately after the cover paint.
9, window sill, platform location spray precautions: because the window sill, platform location is better spray, easy to cause a one-time thick coating phenomenon, in the spray window sill and platform position should be the window sill and platform above the falling gravel removed clean, and then sprayed window sill or platform position.
