Fourth, construction methods
1. Construction temperature and humidity: the temperature is between 5℃ ~ 40℃; The humidity is between 30% and 85%. Do not work in wet or cold weather (temperature below 5 ° C or above 35 ° C, relative humidity greater than 85%).
2. Surface treatment: Before painting, the external wall base must meet the following requirements: the base should be firm, no cracking, no powder, no sand, no empty drum, no peeling, no lime burst point and no old coating with poor adhesion; The surface of the base should be flat, the flatness deviation of the wall should be less than 5mm, and the surface should be flat and not only; The facade is vertical, the Yin and Yang Angle is vertical, the square and the missing edge are off, and the depth of the partition joint is consistent and horizontal and vertical; The base should be clean, and the surface should be free of dust, no floating pulp, no oil stains, no rust spots, no mold spots, no salt precipitates and no moss and other debris; Mold and algae must be cleaned; The base should be dry, and the moisture content of the base should not be greater than 10%; The pH value of the base should not be greater than 10. Before coating, the base should be accepted and qualified before painting construction.
3. Dilution: Before use should be stirred evenly, in order to achieve the best brushing effect, rolling coating, brushing can be diluted with no more than 20% (volume ratio) of water according to the actual situation, if the use of airless spraying, can be diluted with no more than 30% (volume ratio) of water according to the actual situation.
4. Construction tools: wool brush, roller (recommended), airless sprayer, etc.
5. Recommended number of construction passes: [usually 1 ~ 2 passes]

5. Instructions for use
1. Before painting, ensure that the surface of the cement wall is firm, smooth, dry, clean and free of floating dust and oil. Note that the moisture content of the wall should be less than 10%, and the pH value of the wall should be less than 10.
2. For the new concrete wall, the coarse sand and loose attachments that protruded from the surface should be removed with the shovel knife first, and the putty of the external wall should be scraped to level; Generally, the wall needs to be embedded with 2 to 3 walls of putty, and the first batch should pay attention to leveling the obvious defects of the wall, such as large water bubble holes, sand holes, honeycomb, pockmarked surface and collapse inequality, for the larger defects to be partially levelled several times, the second and third putty should pay attention to leveling the large surface, and finally grind with 600 mesh sandpaper.
3. For the old wall, the floating ash and powder should be removed first, and the parts such as sand and warping should be removed. For the parts with oil, the original coating should be removed first, the application of detergent that can not be removed is thoroughly cleaned, and the wall is cleaned up with the external wall putty batch embedded 1 to 2 times.

Vii. Security Matters
1. Air circulation should be maintained during construction, and the paint should be away from direct sunlight and heat sources.
2. To avoid contamination of skin and eyes or inhalation of excessive paint mist, please use masks, gloves and other protective equipment. In case of eye contamination, wash immediately with plenty of water and seek medical treatment.
3. Keep out of reach of children.
4. Wash the painting tools with clean water immediately.
