The construction process of water bag and colorful exterior wall coating ( 2)

Second, cement asperity note 1 preparation: paint on the surface of the water content should be lower than 8%, if you have any oil, dirt and surface dirt, must first clear. If the paint surface have float ash, honeycomb, such as uneven phenomenon, should be tinkered with before construction and leveling. 2 according to the construction requirements and construction details for three purposes: permeability primer is about 0. 15 kg/square meters. Waterborne multicolor paint under the same color paint is about 0. 3 kg/square meters. Waterborne multicolor paint coating about 0. 4 kg/square meters. Acrylic acid polyurethane varnish 0. : 25 kg/m2 4 primer evenly infiltration primer on the grassroots, infiltrate into cement is smooth surface, can adjust the absorption of the base surface uniformity, increase the surface strength of cement and smooth surface. Coating process, should pay attention to the basal surface is dry, prevent infiltration primer for basal surface moisture permeability, in the basal surface film formation, effect to the coating adhesion. The same color primer (5 相同颜色启动) Two types: ( The same color) Primer application can increase the base of the tensile strength and adhesion material, and provide complete continuous joint waterproofing membrane, avoid joint crack ooze water. Spraying is the main method. Construction, wind pressure and the nozzle diameter should be paid attention to the coordination, to ensure uniform coating. Construction interval should be more than 4 hours. 6 jointing: jointing tape should be according to the plan of design with a chalk line paste and calibration. Positioned required specifications of the tape on the calibration parts. Adhesive tape, firmness, and should be paid attention to so as not to fall off. Should be planning and positioning of the end of the tape, upper and lower, so that the tear. 7 secondary coating: color paint coating is the first to test the spray gun diameter, pressure etc. According to the appearance of the coating, spray paint in large quantities. Spraying, the spray gun should be at a certain speed and distance of the operation, the nozzle and the spray coating surface shall be maintained in parallel. The end of the spray should be in joint position. Continue to spray, not dry coating is required. If dry, fine particles is very easy to overlap. The best one in the same area. So in the basal surface is not dry continue to spray. 8. Directions: tear tape. After coating the coating material, according to the connection position with initial and plan, up and down, in turn, will be torn off. Be careful not to damage the integrity of the slotted.
