Many people think that the cause of sand on the cement floor is man-made. In fact, it is not just man-made but there are other reasons. For example, if the cement ratio is light, it will be affected if it is not well prepared. To put it simply, during the decoration process, the ratio of water to sand and gravel is too much, and the cement material is too little, thus forming The water seepage of cement mortar will reduce the strength of the surface of the cement floor, which will lead to the cause of sanding on the cement floor. In addition, the quality of the purchased sand is not up to standard, and there will be certain quality problems when using cement and lime. If you use unqualified cement or substandard lime, it is likely to cause sand on the ground .
Concrete hardener is specially developed to solve the problems of dust, sand and insufficient strength on concrete floors and walls. It is a new type of water-based composite material with a unique formula. It can penetrate 3-10mm into the surface of concrete to form a three-dimensional network of dense whole, thereby greatly improving the surface strength of concrete, hardening the base layer, and preventing sand and dust. The effect and service life are the same as those of concrete, and the construction is simple, just paint on the concrete surface.
