Rough surface water package more colored stone coating for cement construction pay attention to the matter

1. Adjustment of basic level surface, remove dust and cement powder crumbs, its clear, and level off or repair the surface again. 2. At the grass-roots level surface treatment: the easiest and most difficult to deal with rough surface is powder sand surface. Generally speaking, the rough surface of the touch will drop to the ground, or fine sand powder will be iron objects scratch. This is the most difficult treatment. Usually, the rough surface with wood float, this is the most possible problem mentioned above. At ordinary times, therefore, had better use iron float or steel float will surface, so as not to appear this kind of phenomenon, on the surface and recover time should be paid attention to. Screeding should be used immediately after the 'main construction technology of' iron ( Steel) Trowel. Ready to paint on the surface of the water content should be lower than 8%. On the surface of the oil pollution, dust and dirt should be clear in the first place. If the paint surface have float ash, honeycomb, such as uneven phenomenon, should be tinkered with before construction is flat and level. 2. According to the construction requirements and construction details for the construction of 3. Multi-functional primer dosage is about 0. 15 kg/square meters. The same color primer water-based colorful coating is about 0. 3 kg/square meters. Waterborne multicolor paint coating about 0. 4 kilograms per square metre. Silicon a crylic-acid varnish is about 0. 25 kg/m2. 4. Coat: permeable primer coating evenly on the grassroots, seeping into the cement, 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. 5. Two (same color primer coating: The same color) Primer application can increase the base of the tensile strength and adhesion material, provide complete continuous joint waterproofing membrane, so as to 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. Joint: joint tape should be according to the plan of design joint with a chalk line mark. Mark part should be labelled as the standard joint tape. Adhesive tape, firmness, and should be paid attention to so as not to fall off. The tail end of the seam tape, upper and lower should be designed to be easy to tear. 7. Intermediate coating: color paint coating need to first test conditions, such as spray gun diameter, air pressure. 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 without spray drying. If dry, it is difficult to resist the weight of the tiny particles overlap. The same location and the size of the area should be completed at a time. In the process of spraying, the best in the basal surface does not continue to spray drying. 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. 9. Paint coating: transparent paint can use ordinary paint spraying coating. When spraying uniformity should be paid attention to, in order to avoid the uneven coating caused by uneven luster. 10. Clean: after spraying, curing materials shall be removed, and clean up the contaminated parts.
