How to protect the cement mortar protective layer?

The cement mortar protective layer is often used in the waterproof industry. However, if the maintenance of the cement mortar protective layer is not in place, it will also have cracks, and the natural waterproof performance is completely absent. How to protect the cement mortar protective layer? How can we ensure that the cement mortar protective layer will not crack?

The main method of curing cement mortar is natural conservation. Natural conservation refers to the maintenance of covering mortar, watering, wind, heat preservation, etc. under natural conditions (higher than +5 Â°C). Natural conservation covers watering and plastics. There are two types of film curing.

Covering watering and curing shall be covered with appropriate materials such as straw curtain, sawdust and wet sand within 3-12 hours after the mortar is poured, and often watered to keep it moist. The date of watering maintenance shall not be less than 7 days and nights. The number of watering times per day is suitable to keep the mortar in a sufficient wet state. When the temperature is above 15 Â°C, the water should be watered at least once every 3 hours during the first three days of the mortar pouring, and water should be watered twice at night. In the future maintenance, water should be watered about 3 times every day and night. Under dry weather conditions, the number of watering should be increased appropriately. Large-area floors can be protected by animal water.

The plastic film curing is covered with a plastic film to isolate the mortar from the air, the moisture is no longer evaporated, and the cement is condensed and hardened by the hydration of the moisture in the mortar.
