We have heard of all the spray paints, and we all know that it is generally used when we decorate the house, but when we were working, we found that we didn’t understand it at all. However, it is an indispensable project during the renovation, so we need to know the painting process before the decoration. Today small just like we take a look at the painting process painting process and construction considerations it!
Spray paint process:
(1), painting
Painting the paint on the surface of the object with a manual brush is called painting. Its characteristics are: saving paint, tooling, easy to apply, easy to master, and flexible. The disadvantages are: high labor intensity and low productivity. For quick-drying paints, the applicability is poor. If the operation is not skilled, the paint film is prone to cracks, sag and unevenness. Before painting, the paint must be evenly mixed (to prevent precipitation of pigment during storage), and adjusted to the appropriate viscosity, generally judged by experience: after lifting with a brush, the natural drop of each minute is 30-50 drops/min. should. Less dip and more brush, from top to bottom, from left to right, first inside and outside, first oblique and straight, first difficult, easy to apply, vertical and horizontal brushing. The last time you apply the brush, you should also pay attention to: the vertical surface should be from top to bottom; for the horizontal surface should be in the direction of light.
(2), painting
Using a special spray gun as a tool, the compressed air is used as a paint flow, and the paint is sprayed from the nozzle of the spray gun into a uniform misty liquid, and uniformly dispersed on the surface of the object is called spray paint. The characteristics of the paint are: the film is thin and uniform, smooth and flat, all parts can be sprayed, no dead angle, high construction efficiency, 5-10 times better than painting, suitable for large-area surface and artificially difficult to apply Brushed dead angle deformed surface.
Painting construction precautions:
Prevent too dry
During the painting process, the air humidity should be changed. If the humidity is too high, the paint will dry very slowly. This will not only affect the progress of the project, but also affect the quality of the paint in the decoration. If it is too dry, then it will be too dry. It will make the paint dry too quickly, and cracks will occur, so it will not be worth the loss.
Dark paint should pay attention
If you like the darker living room space, you will naturally choose a darker paint. It should be noted that when using dark paint, try not to add any thinner to the paint. The paint we used did not show chromatic aberration, and if the color difference was slightly noticed, the whole room would be difficult to read.
Pay attention to fire prevention during dry season
Paints such as paints are relatively flammable and explosive, so pay special attention to fire prevention during the dry season to avoid accidents due to temporary scams. At the same time, when choosing materials such as paint, pay more attention to the relevant national standards. Some paints do not seem to have much problem, but they are not strictly enforced according to national standards on some issues such as safety. It is also very dangerous to use.
Paint stain on the surface
The appearance of stains on the surface of the paint is very affecting the appearance. We should pay more attention to these problems during the construction of the paint to avoid affecting the overall beauty. When we encounter such a problem, we need to analyze the root cause of the problem and find out the cause before we can solve it. We can first apply a primer containing aluminum powder to the part to be painted before the start of the paint construction, so as to avoid a similar problem to a large extent.
The paint process is actually a very deep study. They all say that the three-point woodwork is seven-point paint, so we still need to pay more attention to it when painting. The above is the small-scale today's painting process and paint painting construction precautions. This is the end. For more information, please stay tuned to the renovation home.
