Such as construction on wet base
.
However, due to the volatilization of a large number of easily resistant organic solvents during construction, it is easy to pollute the environment
.
Internal corners, upper and lower openings generally need to be painted with a brush in advance
.
The quality of base treatment directly affects the adhesion, service life and decoration effect of the coating, so we must pay attention to this process before coating construction
.
Whether it is water-soluble or solvent type, the putty layer is required to be firmly combined with the base course and coating surface course
.
In recent years, China’s architectural coatings industry has developed rapidly, the demand for various new architectural coatings is growing, and has shown good technical and economic effects in practical application
The second course is leveled on this basis and polished with fine sandpaper

shall be covered with plastic to prevent water splashing
.
It has the characteristics of rich expressiveness, strong three-dimensional sense, flexibility, plasticity, strong adhesion, scrubbing, acid and alkali resistance, no fading, no peeling, no cracking, easy maintenance and recoating
.
Then wash it with clean water
.
Because the film is compact, it usually has the characteristics of good hardness, luster, water resistance, acid and alkali resistance, good weather resistance and pollution resistance
.
With the continuous development and progress of social economy, buildings increasingly pursue external aesthetics, which requires complex exterior wall decoration
.
Empty drum, crisp crack, peeling and sanding shall be cleaned with a shovel and steel wire brush, washed with clean water, and then repaired
.
It is easy to peel and fall off
.
Less than one roll length shall be left for final treatment
.
To control the construction quality, we must work hard on material selection, putty layer, base course drying degree and key details of brushing in order to achieve good results
.
After the rolled wall pattern is dry, cover it with paper for supplementary rolling
.
During the construction of putty layer, try to smooth the interface without leaving joints
.
The requirements and methods of surface treatment are also different for different matrix materials
.
After the elastic coating is applied on the outer wall, with the volatilization of the solvent contained in the coating, the film-forming substances and other nonvolatile components form a uniform and continuous film
.
Before the initial setting of the top coat of the coating layer, it cannot be washed by rain
.
However, once the construction quality is not controlled well, there will be bad phenomena such as bubbling and falling off
.
