How to avoid grouting material powder, CGM grout material to give you advice

How to avoid grouting material off powder CGM grout material gave you suggest grouting material powder is possible problems in the application, it may be caused by improper construction, in order to avoid this situation, our company specially summarizes the method to avoid grouting material powder or work off, hope can help you use the grouting material. First of all, the grouting material itself has good water retention, prevent serious bleeding in grouting material surface water cement ratio is too large.
