Know the construction process of spraying machine

In the building construction process, we will use a variety of equipment. The use of these different equipment is helpful to the development of our production activities. Spraying machines are used in exterior wall spraying activities. The frequency of use of paint spraying machines is still relatively high. High. What is the performance of the construction process when we use the sprayer for spraying? Don’t underestimate the progress of the construction process, which will affect the spraying effect. Choose the appropriate sprayer to allow our spraying work to be carried out smoothly. It is also more convenient for professional spraying construction personnel to operate.

Grassroots treatment. The base layer should be cleaned and the surface should be cleaned and smoothed. The base layer must be strong. If there are cavities, peeling and other phenomena, it should be repaired and smoothed. Check whether there is any hollow wall phenomenon.

Putty construction. Adjust the putty powder and 108 glue into a paste, stir evenly for local treatment, use gypsum putty for layering and flattening, and wait for 6 hours to dry before spraying the putty powder. After the putty is air-dried for 8 hours, spray the putty twice to make it smooth and smooth.

Polish putty. After the putty is air-dried for 8 hours, polish it with a sander. Polishing should be done slowly, and the floating dust should be cleaned up after the polishing is completed to avoid affecting the subsequent construction.

Paint construction. When using the spraying machine, two people should cooperate with one person to hold the spray gun and the other person to hold the tube, and spray from top to bottom without leaving construction joints during spraying. Finish one spray and wait for it to dry before performing a second spray.
