colorful paint is so named not only because of its luxurious, beautiful and colorful patterns, but also because of its various classified products, which enable consumers to enjoy strong color patterns, strong three-dimensionality, elegant luster, and good appearance and texture relief paint for decoration. Then the editor below gives an example of a professional and systematic analysis of the construction technology and precautions of colorful paint. Friends who are interested in understanding can refer to their own actual situation for analysis.
1. Colorful paint construction technology
1. For the treatment of the base layer, putty should be embedded in uneven, cracked, and rough surfaces. The putty should have a certain strength and water resistance, and should be lightly sanded with iron sand. Usually it is "two batches and two grinds". Putty is generally not prepared with chemical slurry and double powder, but with white cement, old powder and 107 glue , white cement: old powder = 8:2. In addition, repainted walls should be treated separately according to the type of old paint. Sand the surface with 0-1 grit sandpaper. For use in oil-based paint layers. For emulsion coatings, simply remove dust and oil from the surface. Water-soluble coatings require the use of hot water walls.
2. Cover the spray surface 10-20 cm behind the sun corner with a covering such as plastic film. To prevent the colored coated finish on both sides of the horn from being contaminated by spray paint, the covering should be moved to the spray side. After the sprayed surface is completed, do not pull up the coating film when taking off the cover. Be careful.
3. After the putty is embedded in the base layer and dried, apply the mixed paint evenly on the wall from left to right and from top to bottom.
4. Mix the medium coating evenly, pour it into the spray bucket, and use the special spray gun to spray on the wall from top to bottom and from left to right to form a colorful surface. The nozzle moving speed should be uniform and perpendicular to the wall. . When moving the spray gun horizontally, the nozzle should be in a horizontal position.
5. For oil-based paint, when repainting the old wall, you should first sand it with sandpaper, then spray the colorful paint on the surface, and first apply the middle layer of paint. Same as above, for latex paint, this step should be carried out after base layer treatment, while for water-based paint , the procedure is as follows: primer, middle coat, topcoat.
2. Precautions for colorful paint construction
1. Rinse the spray gun and container with water immediately after use.
2. Pay attention to ventilation and fire prevention during construction because it contains organic solvents.
3. In winter, when the viscosity of the surface color paint is too high, the packaging container can be heated in water at 50-60 degrees.
4. Do not thin this coating with thinner and water.
5. Do not mix the middle coat with the base layer.
6. Avoid spraying colored paint on the surface in rainy days and high temperature climates. Pay attention to the influence of climate on the construction of this coating. Construction is not allowed when the construction environment is below 5 degrees Celsius to ensure the gloss, color and durability of the colorful paint. The construction interval of each coating should be determined according to different climates.
It can be seen from this that in order to ensure that colorful paint can achieve satisfactory effects and advantages in the later stage, it is not only necessary to refer to the early control of product quality and brand, but also to learn from the later construction techniques and precautions. For example, the steps and suggestions from the perspective of professionals are given above, so that friends who are interested in understanding or want to do further hands-on operations can continue to practice to ensure satisfactory results.
