As a new type of coating product of 21st century, the water in sand multi-color coating in the construction coating industry has injected fresh blood into the construction and decoration industry. Sand in water architectural coating has all the characteristics of common architectural coating, and it has strong weather resistance, crack resistance, environmental protection and granite like properties. However, the quality of sand in water multi-color coating needs to be paid attention to, which is a relatively complex coating process. In a word, the following five points should be considered in principle for the construction of the new type of coating water sand coating:
01 raw material selection
We must choose the manufacturers with good quality, because good materials are the basis of the quality of finished products, and we should carry out a careful examination on the spot.
02 batch purchase
Due to the difference of main color points, the material calculation should be done before construction. Try to choose the one with large manufacturer and large number of cylinders to ensure one-time purchase. The more batches are purchased, the more likely quality problems and different color points will appear.
03 base material conditions
Architectural coatings are generally used for heat preservation, but also for ordinary walls. If the outer coating construction is to be carried out, the base material must be carefully and strictly inspected to see if it can meet the construction requirements. If it can not meet the construction requirements, it should not be reluctantly handled or repaired as soon as possible.
04 weather conditions
Exterior wall coating construction belongs to outdoor operation, there will be many weather factors that will directly affect the quality of our project. Such as temperature, wind, precipitation, etc. When the environmental humidity is greater than 85%, rainy days, the temperature drops below 6 ℃, and the wind force is greater than level 4, sand in water construction is strictly prohibited.
05 construction management
The construction of exterior wall coating is a complex and detailed project. In particular, the construction of the outer wall of sand in water multi-color coating should be more careful. For example, the spraying of sand spots in water bags should avoid novice operations as much as possible. For example, before the construction, it is necessary to carry out the preliminary training work to coordinate everyone's work. The fewer the master painters, the better. It's better to have only one person to spray, but it's a bit unrealistic. At least we need to call several master painters together to work out the spraying effect plan and start spraying again.
