1. After a period of time, the embossed floor has a large crack. What is the reason? Can it be repaired?
Reasons for the occurrence of large cracks: the base concrete did not meet the C30 standard; the vibration was insufficient; the maintenance was insufficient or the expansion joints were not cut in time; the large cracks could not be repaired, and they could only be cut off and redone.
2. In the construction of embossed floor, I feel that the protective agent is not enough, and the surface layer is not bright enough, why?
Because the previous construction did not meet the requirements of the construction process, the surface of the finished product was not smooth and dense, there was too much sand and pores, and the protective agent penetrated into the finished product in large quantities, so the protective agent did not cover the surface of the finished product.
3. Why does the surface of the finished embossed floor appear white? How to avoid it?
Caused by water quality problems; before applying the protective agent, did not wait until the ground was completely dry. Solution: After finding the whitening place, wash the whitening place with clean water or water mixed with a trace of hydrochloric acid, wait for thorough drying to observe whether there is whitening phenomenon, if there is, repeat the above operation until there is no Only whitening can protect the agent.
4. Construction process of embossed floor:
1). Compression molding process: It is a molding process that uses hardener and mold release powder and mold compression and coating with protective agent in the initial setting stage of the newly made concrete surface layer.
2). Construction of decorative surface layer: After the completion of the construction process of the concrete surface layer of the civil construction until the initial smoothing, the slurry is first lifted and smoothed, then the hardener is thrown on the concrete surface layer and then smoothed.
3). After the hardener process is completed, the mold release powder is then sprayed. When the concrete is not yet solidified, the mold can be used for compression molding.
4). After molding, the ground can be cleaned with a high-pressure water gun after 24 hours in normal weather.
5). After washing, wait for the concrete surface to dry completely, then roll (or spray) the protective agent.
6). The protective agent can be used normally after drying. The normal temperature is about 1-2 days. When the temperature is low, it needs 2-5 days.
