M525 Medium Strength self-leveling
M525 Medium Strength self-leveling , using special cement , fine aggregate and foreign brands of polymer spray powder resins and other raw materials such as cement additives refined, with a high flowability, high plasticity self-leveling subgrade material for medium-sized businesses construction , light industry and other occasions.
Feature:
Fast automatic leveling ground, fast-setting , low shrinkage ;
Construction can be freely controlled thickness ;
Construction thickness of 2-4mm, excellent compressive and flexural strength ;
Environmental.
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:
Substrate must be dry , solid, load-bearing , dust, debris hinder bonding , smooth surface . To ensure self-leveling surface strength and adhesion, absorbent substrate recommend using M318 water-based primer ; stone, terrazzo base surface, tiles and other non-absorbent substrate surface, recommend using MSYH M320 non-absorbent primer for treatment.
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 : ≥ 25MPa ( 28 days )
Flexural strength : ≥ 4.0MPa ( 28 days )
Construction Method:
①Substrate clean up after the first choice of a suitable primer brushing the substrate, when the primer has been absorbed by the substrate , start semistate ( approximately 2-6 hours after the primer construction ) , begin self-leveling construction.
②Poured about 6-6.5L water in a mixing container, then slowly add to a bag a bag of 25kg self-leveling, stirring with a mixer until a uniform slurry without groups, pouring the mixture was uniformly, spread with a special blade tooth mouth control the thickness, just finishing construction mixture to prevent direct sunlight and strong wind blowing.
③The initial setting before self-leveling with anti-foaming rollers rolling ground to exclude when mixed into the air. Transmission capacity can be used (20-40 liters / minute) pumping self-leveling slurry.
Precautions:
As the product contains cement , reacts with water to produce highly alkaline , avoid contact with skin, eyes. In case of contact , immediately wash with water , if the skin or eyes hurt, 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.
