What kind of cement is suitable for floor?

Step 1: Ground base treatment: Before the ground leveling construction, it is necessary to treat the ground base to ensure that the defects such as empty drum and pimple on the ground have been repaired or eradicated. And ensure that the ground base is clean and there are no construction obstacles. In addition, the roots of finished wood products need to be wrapped, and the roots of original indoor facilities need to be wrapped or covered with materials.

Step 2: Facade plastering cake: Determine the leveling thickness according to the type and thickness of decorative materials laid on the ground and the standard line of the finished surface. Generally, the surface plastering thickness is not less than 20mm, and the leveling control line pops up on the wall. According to the leveling control line, plaster cakes around the wall. The size of ash cake is generally 5x5cm, the spacing is 1.5-2.0m, and the upper plane of ash cake is the ground elevation. If the room is large, it must be reinforced. The mixture ratio of mortar materials of plastering cake and standard reinforcement is the same as that of ground plastering.

Step 3: Brush the cement slurry. The role of cement slurry is to make cement mortar more closely combined with the ground. Cement slurry should be prepared according to the ratio of 1: 0.5. When it is ready, brush it on the ground with a broom and other tools to form an adhesive layer.

Step 4: spread cement mortar, that is, after brushing cement mortar, spread cement mortar, and the mixing ratio of cement mortar is cement: sand = 1: 2, and stir it evenly. After paving the cement mortar, pat it flat with a long wooden pole, so that the mortar can be closely combined with the base.

Step 5: the surface is matte polished, and the surface is calendered twice. The first time, when the cement mortar is slightly condensed, and there are footprints when people step on it, but it does not sink, dry the cement surface and then flatten it with an iron trowel. From the corner to the big surface, flatten and polish in turn. Before the final set of cement mortar, press it for the second time, and flatten, compact and flatten the line pressed out for the first time with an iron trowel. And check the flatness with a guide rule at any time.
