Colorful paint construction dry goods technical paste

China Paint Online News Information: Colorful paint in recent years, in the building facade finish system has gradually become the new favorite of the hipsters, charm and surprise effect to bring the perfect feeling of the boomers. However, the construction technology of colorful paint is a work, the selection of spraying tools, spraying technology, grass-roots treatment, the rational use of paint have certain requirements.multicolored coating construction should choose the appropriate climatic conditions surface spraying, suitable climatic conditions are: temperature above 20 degrees C, relative humidity below 85%;Preparation of coating tools: the selection of Japanese imported special multi-color spray gun (using the best spray gun for Iwata 871 and Feng and PZ-25 type), spray gun diameter is generally 2.5mm, air compressor pressure 0.4 to 0.8Mpa, exhaust volume >0.25m3/min. In order to move and use easily, can be used single-phase (220V) lightweight models, in addition to the preparation of rollers, paint brushes, putty scrapers, spoons, labor protection supplies.treatment of construction substrates: removal of floating ash, loose matter, oil pollution, bulge part of the grinding. The re-alkali wall should be brushed with 5% dilute hydrochloric acid solution, and then washed with water, naturally drying more than 72h. On fiberboard, wood board, the nail head for rust-proof treatment, the plate seams with a thin really good slanted strip paste.
to new walls (cement mortar, machetes, paper lime paste), summer week, winter more than 10 days (water content 10%, PH value of 9.5 below); Sub-filling, the old paint film surface with 0 to 1 sand cloth polishing
bottom, medium paint construction: can be carried out by rolling coating, rolling can not be applied at the corner must be painted brush, must not be missed.paint construction: 1. Before the paint packaging barrel is unopened, shake or roll around before opening the lid, and stir evenly with a wooden stick; 2. Check the spraying tool, turn on the air compressor inflatable, adjust the air pressure to 0.35 to 0.4Mpa, connect a lot of colored spray guns with rubber tubes, carry out air gun test spray, observe the pressure in the effective pressure range (0.25 to 0 .35Mpa); 3. After the spray gun is filled with colorful paint, the paint is first test-sprayed on the test plate to adjust the paint emission and air emission to the suitable after moving to the construction substrate spray, the spray gun is vertically aligned to the painted surface, From the wall to maintain a distance of 30 to 1000px, up and down into a right-angle cross-shaped coating, movement to be smooth, not stop moving in, jump forward, so as to avoid the occurrence of piles, hanging, uneven and other defects;4. Spray the corner and corner, first cover a wall near the corner with a shield 10 to 500px, After spraying, and then block the other side, so as not to appear at the corner of the pattern too dense phenomenon, 5. control the amount of spraying, spray excessive will produce hanging, pattern blur, use too little pattern is scattered grainy, the surface appears rough, coating performance indicators are low. Therefore, the amount of paint should be 3 to 5m2/kg.
