Water-retaining agent: Self-leveling materials are constructed on the ground base, and the construction thickness is relatively thin, and the water is easily absorbed by the ground base, resulting in insufficient hydration of the material, cracks on the surface, and reduced strength.

Dry mortar generally uses Portland cement as the cementing material, and the amount of cementing material generally accounts for 20% to 40% of the dry powder mortar; most of the fine aggregate is quartz sand, and the amount is large, and it generally needs to be dried and screened.

Vinyl acetate-co-ethylene copolymers (VAE), available from SLEOCHEM in powder form, are white, free-flowing, dry powders that are readily redispersed into water to re-form a stable emulsion. Sometimes called “solid latex,”
