How to clean the cement mortar after it dries?

It can be removed by the following methods:

1. After the cement concrete floor is paved, it should be maintained in time. In the early stages of maintenance, in order to prevent the cement concrete from being exposed to the sun and rain, the floor maintenance should be done by spraying curing agents or using plastic films.

2. Use the maintenance method of spraying curing agent. The thickness of the spraying agent must ensure that the curing film is formed. The spray should meet the water retention rate ≧85%. Curing agents whose water retention rate is unqualified or which affect the strength of cement concrete shall not be used.

3. When using plastic film for maintenance, its thickness must be appropriate. Where two films are joined, the joint length shall not be less than 1 meter. The plastic film must be tightly covered on the outdoor floor to prevent it from hanging and being torn or lifted by the wind.

4. When using coverings for watering maintenance, water should be sprinkled in time. The number of waterings should be based on weather conditions to ensure that the coverings are always moist during the curing period. Sprinkle water 1 to 2 times a day on cloudy days and every day on sunny days. Sprinkle water 2 to 3 times. When people put coverings on the road, they must not step on the anti-slip structure of the floor, and they must not let people, animals, or vehicles step on the floor.
