Recently, Mr. Wang, who is being renovated, received a phone call from Mr. Wang. Mr. Wang complained to us that he had a lot of paint left on his wall decoration, and he couldn’t return it to the factory when he opened the cover. It was very distressing. This is a serious waste phenomenon. Mr. Wang suspected that the construction workers misled him to buy, because the construction workers would get the rebate fee, but they did not know how to calculate the amount of paint, and there was no research. In fact, there are many reasons for the loss of paint. Only "the right medicine" can be solved.
(1) Material calculation errors
For the first time to prepare for the renovation, the calculation of the required materials, resulting in the use of the paint can not be used, and finally can only be idle, resulting in wear and waste. If the decoration selected is the way of contracting and not including materials, most of the paints are purchased by the owner. When the calculation fails to buy too much paint, and all the seals are opened, the endless paint will cause a lot of damage. Waste and wear and tear.
(2) rough surface of the wall
The roughness of the surface of the base layer is an important factor in determining the amount of loss of the primer. The rougher the wall to be coated, the greater the loss of paint. For projects requiring multiple layers of construction, the smoothness of each layer of paint and the smoothing effect of sandpaper after construction will also have a direct impact on the subsequent coating construction loss.
(3) Improper wall painting method
At present, the coating methods of paint generally include brush coating, roller coating, conventional air spraying and high pressure airless spraying. Although the method of using high-pressure airless spraying is relatively fast, the wear of the coating is much greater than that of conventional air spraying, brushing and roller coating.
(4) Improper selection of construction equipment
When using the spraying method, the different selection of the nozzle will also affect the degree of wear of the coating. In order to meet the requirements of the tight construction schedule, the construction unit or the constructor can achieve higher spraying efficiency, and may use a larger spray nozzle to cause waste of paint usage.
(5) Environmental factors
Various environments around the construction also affect coating loss to varying degrees. In windy outdoor locations, paint losses are clearly higher relative to well-ventilated and relatively closed workshops.
(6) The level of operation of the constructor
Due to the different levels of operation of the individual, different construction operators may have different levels of construction loss during construction, especially in projects that require a large amount of construction.
Concerned about surprises
Label: The amount of paint used for decoration is large.
Previous: The "Red and Black" 7 features of the smart toilet are missing. Next: The safe production of paint companies is more important than Taishan.
