1. Concrete requirements
1) Compactness: Refer to the concrete building strength standard (C25 /4000PSI)
2) Flatness: Using 3m ruler to measure, the error is not more than 3mm.
3) Slop: Ensure the drainage,Horizontal slop is not more than 5‰, Vertical slop is not more than 3‰.
4) Maintenance: The new concrete should maintain no less than 28days, the first 7days should pour water conservation.
5) Crack: the new concrete must cut after pouring water conservation, each part size should be 6X8m. the crack width should be 6~8mm,the depth is not less than 30m
Note: It suggest to build the new concrete ,in case of the old concrete sink ,deformation,or crack too much. the new concrete thickness should be ≥ 80mm.
2.Concrete base processing
1) Cut : The normal crack in right-angle, please cut it in V shape with width in 40- 50mm,the depth in 20mm
2) Wash: Polish the convex and the loose. Clean the floor by water and dilute hydrochloric acid
(concentration: 5~8%) ; Before the next step, ensure there is no dilute hydrochloric acid and the floor is dry.
Note: Marking down the ponding when cleaning, Some projects clean only by water.
If possible, we suggest to polish the base .
3) Primer : Before primer, the concrete base must be totally dry.
Feature: in order to seal the concrete hole, then after buffer coat, it is not easy to delaminating and bubble.
