Plastic flooring should be self-leveling before construction, but some concrete floors are sand-blown, with little strength and very poor smoothness. If this foundation is not treated, it will be self-leveling. In the future, there will be some problems such as bulging and bubbles after plastic flooring is paved. If the simplest method is used to deal with this kind of floor, it will save time and cost, and also ensure that plastic flooring will be paved in the future. No problem. Next, we will share with you our long-term treatment plan of sand on the concrete surface.

　　在混泥土找平處理過程中，有很多時候用戶是通過一些非專業人士處理的。很多時候由于施工不專業，砂漿混泥土采用人工拌和，水泥標號不夠，水泥，砂石料的配比不標準，加水量不太多，砂漿混泥土攪拌不均勻等問題，導致找平后的混泥土地面沒有強度，地面起砂，起灰，按照正常的處理方法是要把原來的找平層全部鏟除，然后重新用標準的砂漿混泥土來找平，但是這種方案施工成本很高。而且所需要的時間長，找平后還需要10-20天的干燥保養時間。這樣一來裝修的時間就會很長，用戶根本沒有時間來等待。遇到這種情況我們的處理方案如下。

　　In the process of leveling concrete, there are many times that users are treated by some non-professional people. Often, because of the unprofessional construction, the manual mixing of mortar and concrete, the insufficient cement label, the non-standard proportion of cement, sand and gravel, the insufficient amount of water added, the uneven mixing of mortar and concrete, etc., the leveled surface of the mixed soil has no strength, the ground starts to sand and ash. According to the normal treatment method, the original leveling layer should be completely removed and then re-leveled. Standard mortar and concrete are used for leveling, but the construction cost of this scheme is very high. And it takes a long time, after leveling, it also needs 10-20 days of dry maintenance time. In this way, the decoration time will be very long, users have no time to wait. In this case, our treatment plan is as follows.

　　先對地面進行全面的清理，清除地面表面的灰塵和沙石。然后用專業的混泥土地面滲透劑，按照1比1加水直接倒在清理干凈的地面上，讓滲透劑完全充分的滲透到地下面，滲透劑滲透后和混泥土產生化學反應，能快速的提高地面的強度。通過48小時的干燥后，如果地面的強度還不能達到想要的標準，那么就用同樣的方法再滲透一次。通過滲透劑滲透過的混泥土地面強度大大提高。節約了時間，一般干燥48小時候就可以開始施工自流平了。如果地面平整度不好，那么可以采用做兩遍自流平。這樣的話成本就比重新鏟除后再用砂漿混泥土找平成本低，而且施工時間還縮短了。如果您有地坪起砂的問題可以來電咨詢，我們將為您提供適合的解決方案。

　　First, the ground should be cleaned up comprehensively, and the dust and sand on the surface of the ground should be removed. Then the professional Infiltrator is used to pour water directly on the clean ground according to the ratio of 1 to 1, so that the Infiltrator can fully penetrate into the underground surface. After infiltration, the Infiltrator reacts with the concrete, which can rapidly improve the strength of the ground. After 48 hours of drying, if the strength of the ground is not up to the desired standard, then the same method is used to infiltrate again. The surface strength of the mixed soil infiltrated by Infiltrator is greatly improved. Save time, usually 48 hours after drying can start construction self-leveling. If the surface roughness is not good, then two self-leveling can be used. In this way, the cost is lower and the construction time is shorter than that of using mortar and concrete to leveling after removing. If you have sand problem on the floor, you can call for consultation, we will provide you with appropriate solutions.
