Generally, after the floor tile is laid for 24 hours, the owner can sprinkle water with a kettle every 5-6 hours and maintain it for 1-2 days. Don't walk on it during maintenance, even if things are paved, you can't trample them at will, which will destroy the hardening effect of cement and the quality of tile paving. Because of the large volume of concrete and the thick cement floor, the floor tiles need to be watered and maintained. When these massive cements have high hydration heat and are exposed to air, especially in high temperature and dry environment, they will shrink sharply and crack easily. All cement must be slag portland cement (low hydration heat and slow early strength growth). This is a structural requirement. The same is true of cement for interior decoration. Whether the wall brick is pasted firmly depends on the treatment of the foundation wall (according to the actual situation, handle the moisture content and smoothness of the foundation wall, and never use the mortar pasted with the wall brick to find the vertical error or horizontal error of the foundation wall.

After that, the key problems of brick are that the thickness error of paste mortar is too large, which leads to different shrinkage values, insufficient or excessive brick infiltration, irregular operation and responsibility. , will pull the brick away), and the standardization of operation. In general, cement mortar will start to solidify after 2 hours, and it can walk on it after 48 hours, but it takes 4 or 5 days to completely dry, so it can be covered with sawdust at room temperature after 24 hours and watered for 48 hours. Don't step on it during curing until it is stable.
