1, grassroots cleaning

At the internal corner where the base of skirting board and rest board intersect with the ground wall, the wall of skirting board needs to be thoroughly cleaned, the mortar falling to the ground and the protruding part that affects the thickness of the surface layer should be chiseled flat, and the reserved buried iron should be chiseled clean.

2. Weld step corner protection steel bar

According to the geometric dimension line of stair step, accurately locate the corner position of step, and weld the fixed corner protector and embedded iron pieces. The position of the corner protector fixed by welding shall be accurate, the error between the height and width of the steps shall be less than 5mm, the height difference between two adjacent steps shall be less than 10 mm, and the corner protector shall be straight and the length shall be the lateral width of the steps. After all the corner protectors are welded, clean the treadboards, and pay attention to protection in the subsequent construction process to prevent deformation caused by trampling and collision.

3. Sprinkle water to wet the floor. Sprinkle water to wet the floor one day in advance, with sufficient water, and keep the ground wet during construction the next day.

4. Brush the cement slurry again. Clean the wet base surface and brush the plain cement slurry with a water cement ratio of about 0.5, and brush it together with the mortar to prevent air drying.

5. Pave cement mortar pressure head with corner protector as reinforcement, and pave socks cement mortar with mortar ratio of 1:2 and consistency less than 35cm; Spread it firmly with a wooden trowel, then rub it flat, pay attention to the founder of the angle of Yin and Yang, and check it with a ruler at any time; Sprinkle 1: 1 dry cement sand surface slightly after the water is poured, and smooth it with an iron trowel after absorbing water.

6, the second time calendering

Press the flat head completely. When the cement mortar condenses and people step on it but it doesn't sink, press it for the second time with an iron trowel. Require no pressure leakage, flat light, horizontal and vertical angle of yin and yang.

The above is the matters needing attention about the decoration of cast-in-place stairs and the construction process of cement stairs, hoping to bring help to friends in need.
