M518 Common self-leveling
M518 common self-leveling, using special cement, fine aggregate, polymer spray powder resins and other raw materials such as cement additives refined, with a high flowability, high plasticity self-leveling subgrade material for laying all types of resilient flooring , carpet, wood floors and other ground material provides smooth, intact, ideal solid substrate, non-toxic, harmless, green products. Apply compressive strength less demanding place in homes, offices, small commercial facilities.
Feature:
Fast automatic leveling ground, fast-setting, low shrinkage;
Construction can be freely controlled thickness ;
Construction thickness of 2-4mm;
Affordable.
Applicable Substrate :
Applicable to all types of flooring, carpets, tiles, floor tiles and other materials, to provide smooth, intact, solid substrate ideals, is non-toxic green products.
Substrate Treatment:
The substrate must be dry, firm, bearing, dust, debris hinder bonding, smooth surface . Has a good compressive strength. In order to ensure the self-leveling surface strength and adhesion,Recommend using M318 multi-function water-based primer. Stone, terrazzo base surface, tiles and other non-absorbent substrate surface, recommend using MSYH M320 non-absorbent primer for treatment.
Construction Method:
①Substrate clean up after the first selection M318 water-based primer brushing the substrate, when the primer has been absorbed by the substrate, in a semi-state ( 2-6 hours after the primer construction ), begin self-leveling construction.
②The accession to the 6-6.5L of water in the mixing vessel, and then slowly add a package of 25kg self leveling, with stirring for 2-3 minutes, the mixture is poured, evenly spread, using special tooth mouth scraper control thickness, the mixture must be used within 20 minutes, just the construction of good self leveling to prevent direct sunlight and the strong wind.
③The initial setting before self-leveling with anti-foaming rollers rolling ground to exclude when mixed into the air.
Technical Parameters:
Mixing ratio : 25kg powder : 6-6.5L water
Coverage: Approximately 3.5kg/m²·2mm
Constructability time: About 20 minutes
Viable human time : About 4 hours later
Flooring may need time : Waiting for self-leveling completely dry
Compressive strength : ≥ 20MPa ( 28 days )
Flexural strength : ≥ 4 MPa ( 28 days )
Precautions:
As the product contains cement, reacts with water to produce highly alkaline, avoid contact with skin, eyes; once contact, immediately flush 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 Shelf life is 6 months.
