Now, more and more floor decoration is used to use self-leveling mortar to decorate the floor. With its own advantages, self-leveling mortar has also lived up to expectations and solved many floor problems in the floor, and has also brought many conveniences.
self-leveling cement mortar fast hardening, high strength, short construction period, 1-2 days can be used, and the delivery and use cycle is short. It is very suitable for floor projects with tight construction periods of , and the project is also basically used.
has said so much, and then we will explain in detail the self-leveling mortar and how to construct it.
cement self-leveling mortar introduction:
cement-based self-leveling mortar introduction: Cement-based self-leveling is a dry-mixed mortar made up of special cement , super-speeding components, natural high-strength aggregates and organic modified components. After mixing with water, it forms fluid slurry with excellent fluidity, which can be quickly spread and leveled with manual assistance.
hardening speed, days can be used for people, but it cannot be made with high thickness. Generally, -8mm.
Features:
1. It has good liquidity , spread evenly, and can well flow into the gap of floor heating pipes .
2. The hardened self-leveling mortar is uniformly distributed , and has good resistance to segregation .
3. The dense structure of self-leveling mortar is conducive to the uniform heat of upward conduction , and can ensure the thermal effect of very well.
4. It has high strength and fast hardening. Usually, you can get on someone in 1-2 days.
5. The shrinkage rate is extremely low, is not prone to cracking , is not prone to delamination and hollowing .
cement self-leveling ground construction practice:
1, sealing work
blocking work is considered the preliminary preparation work for construction. Before the construction of the cement self-leveling ground, should block the door , drain outlet and other parts that may be leaked .
2, base layer processing
Base layer processing includes two aspects. One is that there should be no debris in the construction area, and the other refers to the protrusions and depressions on the ground of the construction area. To remove protrusions and fill depressions. The overall requirement is flat and free of debris .
3, environmental
After the base layer is processed, should close the door and windows to avoid the influence of wind and dust . In addition, if there is a place where is sunny and , can appropriately block , otherwise it will affect the surface quality of the cement self-leveling mortar.
4. Apply interface agent
The function of the brushing interface agent is to cover the back cover. Generally, is applied twice . After the first time is dried, apply the second time. Do not miss it during the brushing process. is as even as possible.
5. Stir
After the interface agent is dried, add water to stir the cement self-leveling powder. The proportion should be strictly followed by the manufacturer's instructions or the guidance of the technical personnel. Try to use mechanical stirring as much as possible to facilitate even stirring.
6. Pouring
After the cement self-leveling powder is added with water and stirred into slurry, you can start pouring. The flow of cement self-leveling mortar is very large, after all, it is limited. Therefore, during the pouring process, you can use auxiliary tools such as scrapers. At the same time, you need to use an exhaust roller to roll it on the cement self-leveling surface to play the role of exhaust. avoids the generation of small pores on the cement self-leveling surface .
7. Maintenance
After the pouring is completed, the cement self-leveling needs to be maintained for a certain period of maintenance. Maintenance is carried out according to the product instructions of each manufacturer. During the maintenance period, no one is allowed to walk, and the air is kept from circulating .
