Installation Guide
Substrate Treatment:
The base must be dry, firm, load-bearing, dust-free, no obstruction to bonding sundries, smooth surface;
Base without hollow drum, with good compressive strength; In order to ensure good adhesion, the base is sealed with MSYH primer. M318 water-based primer is recommended for absorbent base and M320 non-absorbent primer is recommended for non-absorbent base.
Construction method:
1.Cleaning up substrate, choose the appropriate primer, when the primer in the dry state, then begin self leveling operation.
2. Pouring 6L water into container, slowly adding a bag of 25Kg powder, stirring for 3-5 minutes to uniform , evenly spread, with a spatula to exhibit uniform as required thickness, prevent direct sunlight and the wind blowing.
3.Before the initial coagulation, the use of special defoaming roll to exclude the air, to ensure uniform thickness.
Notes:
As the product reacts with water to produce highly alkaline, avoid contact with skin, eyes. In case of contact, immediately wash with water; If skin or eye injury, seek immediate medical attention. This product will not produce the body, environmental impact material after hardening.
Packaging and Storage:
25kg composite bag. The product shall be kept indoors, pay attention to moisture, prevent freezing, solarization. Stacked on pallets no more than eight layers,Under the condition of good moisture-proof measures the shelf life of six months.
