Ground construction process for Emery floor
1. Corner reinforcement:
① The corners should be disposed according to the requirements of the specification;
② Spread the material by hand along the sideband 100 ~ 150mm wide;
③ Smoothing with a spatula;
④ If a cutting seam is required, a hardener should be applied to the place where the cutting seam is set, and the surface should be wiped with a steel spatula.
2. Coverage of design materials:
① Divide the construction surface into a certain area;
② Prepare enough materials for the two-stage construction at the designated locations;
3. Laying hardener (first stage):
① Determine the initial setting time of concrete (light pedestrian traffic leaves a mark of about 3mm);
② Spread 3/5 of the material evenly on the concrete surface. Spread the hardener evenly to prevent uneven surface rigidity and make the surface fall off due to changes in environmental conditions during later use.
① The surface of the material to be spread for the first time becomes dark, indicating that sufficient moisture has been absorbed from the base concrete;
② Use a wooden wiper or electric trowel with a grinding disc to smooth it out;
③ Do not over wipe
④ Check the flatness and adjust it in time with a 2 meter aluminum ruler;
⑤ The corners need to be treated with a spatula;
⑥ Make sure all parts are completely compacted.
6, wipe out:
① The surface to be darkened a second time (the time required is slightly longer)
② Smooth with a steel spatula or an electric spatula with a grinding disc.
After all the materials have been spread and polished, about 1 to 2 hours after the concrete is hard enough not to be damaged, use a diesel trowel with a slanted blade angle to collect the light to the required level.
After the construction of the hardener is completed, in order to prevent the surface moisture from evaporating rapidly and to ensure the stable growth of the strength of the wear-resistant material, YY-HP should be used to maintain the surface within 1 to 6 hours after the construction is completed. The specific use method is as follows:
(1) The material should be stirred well before use.
(2) YY-HP can be evenly sprayed on the surface of the concrete surface after the final calendering is completed. The construction time is about 1 to 6 hours after calendering (depending on the ambient temperature and humidity at the time). If there is no spraying equipment, you can also use a soft brush or roller for construction. Care should be taken during construction to avoid damage to the emery surface layer.
9. Cutting and filling:
Within 2 days after the hardener ground construction is completed, it is recommended to cut the grids according to the design requirements of the building structure. Generally speaking, for concrete frame structures, the column mesh sawing is usually used, and the sawing can also be performed according to the requirements of Party A.
