Understanding the Construction Precautions for Imitation Stone Coatings
Stone-like CoatingWhat should be noted during the construction of stone-like coating? Let's analyze it briefly together. Wall base treatment (please refer to GB/T50210-2001). 1. Flatness check: Use a 2m ruler to check the standard and mark obvious uneven areas with colored pens. 2. Patching: Hollow areas should be treated with a partition, and holes or obvious depressions should be repaired with cement mortar, while less noticeable areas can be filled with oily patches. 3. Sanding: Use a grinding wheel to match the protruding parts with the repaired areas (2 mm). 4. Dust removal and cleaning: Use brushes, scrapers, etc., to remove attachments and dust from the wall. When repairing large areas of the wall, pre-treatment of the divisions should be done. For the metal rods extending from the wall, rust treatment should be done first to prevent future water pipe contamination of the coating surface. 5. Positioning and snapping lines: It is required to use sheets or markers to position the separation seams, with a width of 2.0 cm for the separation seams, and a positioning line of 1.6 cm should be snapped with a chalk line.
Stone-like CoatingWhat should be noted for the base coat painting? Let's analyze it briefly together. 1. When brushing, use a brush or roller and strive to apply it evenly. 2. Use a cross-rolling coating method to ensure no missed spots and an even coating. 3. The coating should be done from top to bottom in the building, with each painting section divided by natural seams, corners, and junctions, and each coating area should be completed as much as possible in one go. 4. Non-compliance with technical requirements and patching treatment. 5. The base coat should be dry (about 12 hours) before proceeding to the next process.
The following points should be noted for the division and protection of the finished stone-like coating: 1. The intermediate coating should use the main color of the coating. 2. When coating, use spraying or rolling methods. 3. Cross spraying or cross rolling should be used to ensure an even coating and uniform color. 4. Painting should be done from top to bottom in the building. 5. Patching treatment for non-compliance with technical requirements. 6. After one coating, a second coating should be done at specified intervals.
What is the sprayable multi-color coating of stone-like coating like? Let's analyze it briefly together. 1. No filtering is needed, avoid vigorous mixing, just place the main material in the pressure tank for spraying. 2. Use the spraying method to ensure the main layer is even, with uniform thickness, and adjust the air pressure to the appropriate size, paying attention to the internal pressure of the tank, ideally adjusting to 0.05 MPa. 3. One or multiple variable sprays can be done, first spraying a thin layer, then spraying two cross sprays. The spray gun should maintain a certain speed, and the nozzle should generally be perpendicular to the spray surface, with a suitable distance of 30-40 cm. 4. After spraying, it needs to dry completely for more than 24 hours before applying the mask coating. 5. Requirements: consistent color, no obvious flow, leakage, or penetration phenomena. 6. For color separation and division, tape should be used, and each segment should be immediately torn off after application.
What is the gloss finish paint of stone-like coating like? Let's analyze it briefly together. 1. Use a spray gun for spraying, and each sprayed surface should be completed in one go as much as possible, with construction done from top to bottom in the building, using natural seams and corners as boundaries. If there are no seams in a large area, the upper and lower connection method should be used to avoid traces at the paint joints. 2. Precautions when using spraying tools. (1) Air pump pressure is 8 kg, the diameter of the air pump pressure cylinder pipeline should match the diameter of the airbrush pipeline, with the airbrush pipeline diameter being 8#-12#. (2) The discharge pipe from the pressure cylinder to the spray gun should be less than 4 meters. (3) Control the air pressure in the pressure tank at 0.5-1.5 kg (below 1.5 kg). (4) The pressure tank cap needs to be tightened with a wrench, with no air leakage. (5) The pressure cylinder, pipeline, and spray gun should be cleaned thoroughly after each use, and during breaks in spraying, the spray gun can be soaked in clean water to dry the inlet material and prevent clogging.
