1. After the initial setting of concrete, the construction of wear-resistant flooring is carried out. The standard for the initial setting of concrete is generally that after pouring and compacting the concrete for 4-5 hours (depending on the weather), the surface of the concrete should be visually free of bleeding or leave a 3-5mm mark using the "finger pressure test method".
2. Construction technology of wear-resistant flooring materials
(1) Remove the floating slurry and use a mechanical trowel to polish the surface of the concrete to make it compact.
(2) Spread two-thirds of the specified amount of wear-resistant flooring material evenly on the concrete surface, completing one spreading operation. After the wear-resistant flooring material absorbs a certain amount of moisture, perform mechanical trowel polishing operations. Then, after the wear-resistant material has hardened to a certain stage, a secondary material spreading operation (one-third of the material) is carried out.
(3) The mechanical trowel operation should be carried out at least three times after the wear-resistant flooring material that has been spread twice has absorbed moisture. Mechanical trowel operations should be carried out in a criss crossing manner.
(4) The surface polishing operation for wear-resistant flooring materials involves using a mechanical trowel or manual spatula to continuously polish until the surface is completely smooth. Use a manual spatula to complete areas where mechanical construction is not possible, such as column edges or wall corners.
