1, before cement self-leveling construction, attention should be paid to the mixture ratio of cement self-leveling, and the appropriate mixture ratio has good strength. The ground without strength is often the source of ground ash in the later period, and the starting position of water-greasy self-leveling is also very important. Attention should be paid to ensuring the flatness of the whole ground.

2. A dry powder mortar material, which is made of special cement fine aggregate and various imported polymer additives in strict proportion, is stirred with water to form a self-leveling slurry, and does not contain harmful gases and substances. Now it has been widely used in factories, hospitals, garages and other places.

3. Surface treatment of the base-remove oil stains and loose objects. If there are holes or grooves, they should be leveled with mortar or special putty first. If the height is too high or the bumps should be knocked off or smoothed, so as to save materials and improve the construction quality.

4. No maintenance is required at room temperature. Under high or low temperature conditions, after initial setting, measures such as watering or covering wet sacks and straw mats must be taken for curing 1 ~ 3 days. The ground with heavy traffic needs to be maintained for 3 days before it can pass.
