一、Product Introduction

A self-developed self leveling mortar is made by mixing and processing special cement, selected aggregates, and various active ingredients. Mainly used for repairing general cement pavement and yard, underground parking lots, workshops, shopping malls, exhibition halls, office buildings, and commercial and residential buildings. It has the advantages of smooth repair surface, high strength, and convenient construction.

二、Main characteristics

Convenient construction, mixing with an appropriate amount of water can form a slurry that is approximately a free fluid, which can be quickly unfolded and achieve high flatness;

Fast construction speed, high economic benefits, and shortened construction period;

Good adhesion performance: Strong adhesion, excellent adhesion performance when bonding with concrete and mortar, resistant to frost and sulfate corrosion, non-toxic and non corrosive;

Good crack resistance: able to adapt to the deformation of concrete base without cracking or falling off. There is no cracking, peeling or peeling phenomenon during thin layer repair;

Can be used in damp substrates and environments, and can be used as repair materials.

五、Packaging specifications

Packaging: Paper bag packaging, 25kg/bag, 50kg/bag.

六、Usage

Before construction, ensure that the construction base in the area is solid, clean, free of oil stains, floating dust, loose objects, and other stains;

Use mechanical or manual methods to chisel and groove the construction base surface, rinse the construction base surface clean with water, and apply two coats of interface agent;

Mix the mortar slurry according to the recommended water to material ratio of 0.24 to 0.26. When mechanically mixing, the mixing time should be 5 to 6 minutes;

Pour the mixed slurry into the construction surface, level it with a scraper, and cover it with geotextile for wet curing for seven days when it finally sets.

七、Precautions

The mortar constructed in summer should be protected from direct sunlight and covered with wet geotextile for moisture preservation and curing; During winter, attention should be paid to insulation and maintenance. Hot water mixing and covering with rock wool blankets can be used for insulation. Construction cannot be carried out on rainy days or when the temperature is below 5 ℃ and the wind speed is above level 5;

Storage: Store in a dry and cool place, ensure ventilation, and avoid direct sunlight;

Under normal storage conditions, the storage period is 90 days. If it exceeds 90 days, it must be verified through testing before use.

八、Typical applications

This product is produced in accordance with the JC/T 985-2017 standard for cement-based self leveling mortar for ground use
