How to Make Putty Powder Achieve the Shiny Effect?

The main factors that affected wall putty drying faster by external factors, internal factors, and scraping thickness. External factors are mainly the degree of wetness and dryness of the wall, weather temperature, humidity, light, etc. The main internal cause is the raw material ratio and the additive ratio of putty itself; Batch scraping thickness also affects the drying speed of the putty wall. 

• 1. Wall is too dry: if the wall is too dry, it will absorb a lot of water in the putty, and the putty powder will dry quickly after being put on the wall. In this case, the dry humidity of the wall should be checked first, and the wall should be sprayed with water before the putty, and the construction can be performed after there is no bright water. 

• 2. Temperature is too high: the temperature is high, the light is strong, the water evaporation speed is accelerated, and the putty powder dries quickly on the wall. Especially in summer, to avoid high temperatures, and strong illumination during the period of batch scraping putty, choose the morning and evening low-temperature times for construction. In addition, ingredients increase the amount of cellulose ether added slightly, increase water retention, and reduce water evaporation too fast.

• 3. The problem of additives: cellulose ether is generally added in putty powder, which mainly plays an important role in water retention. Add cellulose ether, to choose the quality of reliable cellulose ether, poor quality, putty water retention, and scraping difficult. The viscosity of cellulose ether should also be moderate, the viscosity is too high, the scraping up is too thick, and labored; The viscosity is too low, the water retention is not enough, and it dries out easily. Generally in the putty powder of 200kg grey calcium, add 3-4kg viscosity of 150000 HPMC. In addition, you can consider adding wood fiber, the price is cheap, and you can retain water and thicken, you can also add a small amount of starch ether, increase the construction, and scrape feel the light non-stick knife. 

• 4. Putty quality problems: some manufacturers in order to save costs, putty ingredients with cement and calcium ash. Putty with highly alkaline cement, will cause hydration too fast, resulting in plastic loss too fast, and construction time is shortened; Grey calcium water absorption is very large, if the amount of add is large, it will also cause putty on the wall dry fast. So in the ratio of raw materials, reduce or not high alkaline cement, reduce the amount of calcium ash, if there is no special purpose, in general, ordinary putty only needs to add 150-200kg of calcium ash enough. 

In the process of putty powder construction, we all want to ensure that the putty wall is bright and strong. How can we achieve the ideal effect? The following is to introduce some reliable construction technology for putty powder for you. 

HPMC for Wall Putty

The construction of putty powder is very exquisite. In general, it is divided into three steps. It is very important to master these three steps. The construction of putty powder needs to be divided into three times scraping and coating and the specific construction of the workers' techniques vary from person to person. 

First, clean up the wall, and the outside of the dust clean, this is to make putty powder better connected with the wall, for the next step is to lay a solid foundation. The first time has a great effect, we should pay special attention to it must be dry, the drier the better, because dry to achieve the above effect. The drying time of the first pass is normally 24 hours, but the specific time varies due to wall conditions and climate conditions. 

Then is the second time, because of the above the construction side, the construction is to further level of metope, but two can't continuous construction, must wait until the first time after it is dry on the second time putty leveling further, the second time putty mixing is not easy to lose, and the second time to ensure that the putty scraping coat after the moisture is absorbed by the first time be bored with a child as soon as possible After the moisture is reduced to a certain extent, the pressing light can be carried out. 

Then is the third time construction putty powder, it is also important to again after the end of the link, the calendar putty powder, in front of construction should be through this step, the concrete is the second time after scraping the coat slightly to a pulp was followed by coating them a third time, and then start calender, achieve the effect of light, strong, brightness and strength is. 

As long as the construction process is in strict accordance with the above steps, the putty powder can completely achieve a bright and strong effect.
