1. If it is a two-component product, mix the ingredients according to the proportion of liquid, powder and water marked on the product package, and adjust the viscosity of the coating to meet the construction requirements of different parts of the interior and plane. Generally, it can be stirred with an electric stirrer for 3-5 minutes until a uniform slurry of powder clusters is formed, and then it is allowed to stand for 65438 00 minutes to make the slurry fully mature, and then it is stirred for 2 minutes; ? Note: When mixing for the second time, the agitator should be placed at the bottom of the container. Don't do lifting exercise to avoid wrapping the material in the air. The adjusted mud will be used up within 1 hour. ? 2. Use a brown brush or scraper to evenly coat the cement slurry on the fully wet base surface, without clear water, and pay attention to avoid brush leakage. After the previous layer of paint has solidified and produced enough strength, the next layer of paint shall be constructed, and the painting directions of each layer shall be perpendicular to each other. (total thickness1.5 ~ 2mm); ? 3. The joints of the upper and lower water pipes with large cracks and easy deformation should be reinforced with glass fiber grid cloth; ? 4. High-pressure spraying method can also be used for large-scale construction; ? 5. After the coating waterproof layer is qualified, it shall be protected and isolated according to the design requirements. Matters needing attention in construction: 1. During construction, the base should be cleaned to keep it flat, clean and free of dirt; ? 2. Construction must be carried out on the wet base, but there can be no Mingshui; ? 3, 24 hours after the end of the construction should be sprinkler maintenance for 2-3 days; ? 4, waterproof coating packaging should be used up in a short time after opening, not for a long time; ? 5. Do not work on frozen or frosted surfaces, and do not contact for 48 hours when the ambient temperature is lower than 4℃. If construction is really necessary due to the construction period, the construction time can be arranged between sunny days 10:0 ~ 15:00, or warm water (or hot water) can be used to mix materials to speed up the initial setting time and increase the early effect. When the continuous ambient temperature is below minus 4℃, it is suggested to suspend the construction; ? 6. It is not suitable for construction in rain and snow, and the newly constructed surface should not get wet before curing. Within 48 hours after construction, long-term low temperature below 0℃ caused by rain and frost should still be avoided; In the case of poor air circulation or no ventilation conditions (such as closed mines or tunnels), fans or blowers can be used to assist ventilation.
