Water color paint construction process

A, 1 wall foundation requirements. Base should level off, smooth, firm, without holes, crisp powder, such as peeling, peeling, pulverization phenomenon. Yin and Yang Angle should be straight. 2. Surface with no dirt, dust, grease, paint, advertising, colour and other impurities. 3. Brick walls, Windows, such as easy to crack crack parts must be carried out by processing, pool, such as lotus pond water storage unit must be waterproof processing. 4. The various components of metope, embedded parts, plumbing, electrical, air conditioning pipe should be installed ahead of schedule, according to design requirements shall not be exposed to the mortar on the surface of all components. Waterproof wall around should make the necessary antirust processing. 5. Ph value is less than 10, on the surface of the substrate water content is less than 8%. 2. 1 base surface treatment. Cleaning: check and clean the base level, can not have waste, oil, floating dust and other dirt. 2. Water: if the base is too dry, water first, until the walls moist. 3. Repair ( High low repair repair) : the concave and convex part clearly marked with a marker pen. If the hole is apparent, with cement mortar early repair some parts significantly higher. Using sand mill grinding, coarse powder putty to repair is not obvious. Less than 1 flatness requirement. 0 mm, 4. For the quality of the hollow out hollowed part and extend 10 cm part should be removed, and then add putty repair level off. 5. Open base with a chisel, v-shaped formation, and then use putty to repair. 6. If the window edge line of Yin and Yang Angle of straightness is more than 3 mm, should use putty to repair. Before the repair, application of water wet base level, and on the edge of the window cutting groove outward. 7. Use sand paper burnish, 180 after completion of the above processing base, remove loose layer on the surface of the base, to ensure that the bond strength of putty. 3. Fill the glue and patch 1 cracks. 1 when the split joint function. High grade decorative function: can be divided according to the designer or the owner of the free will, increase the stereo feeling, to reflect the adornment concept of owner. 2 have the effect of expansion joint: buffer and lower wall cracking stress, prevent metope micro cracks caused by thermal expansion and cold contraction. (3) to provide flatness convenient operation: after segmentation, relatively split surface flatness than operation the whole bedding face much easier. 2. Tools batch knife, blade, arc tube, scale, mixer, cutting machine, straight edge, ink fountain. 3. The construction method ( 1) The setting of grid nodes and positioning: the depth and width of the grid nodes, the horizontal and vertical direction, and the overall distribution should be carried out in accordance with the requirements of party a, and in accordance with the specifications prescribed by the party a or the elastic line and the grid. ( 2) To horizontal flat vertical frame, frame joint sundries shall be removed or grease, dirt, etc. Rinse the seam dust. ( 3) Points seam filling repair: joint special partial filling putty, uniform depth, before each filled with sand grinding, seam water wet points; Repair the missing foot, etc. Make clear edges. ( 4) Circular tube into half arc after 4, the whole batch of leveling anti-cracking putty batch leveling anti-cracking putty, drag the putty with two meters long aluminum alloy guide ruler, vertical blow again, first level blow again, foot speed and force should be balanced, otherwise will be directed along the ulnar direction to form a wave and affect the flatness; 5. When spraying alkali resistant primer construction ( Brush and roller is acceptable) 。 With airless spray gun evenly spraying thin. Construction temperature above 10 ℃, enhanced additionally is about 0. 25/㎡。 Six, color intermediate paint twice mixing with the curly hair cylinder intermediate paint twice. Be careful not to miss paper or paper is too thick, lead to sagging. Roller coating on the surface of the particles must be kept evenly. Seven.
