Cementitious thick layer self-leveling

Product Description

M625 Cementitious thick layer self-leveling, use the special cement, fine aggregate, polymer spray powder resin and other raw materials such as cement additive refined but become, have good liquidity, can fast automatic leveling the ground and is suitable for large and medium-sized civilian residential and public buildings, commercial and industrial buildings, warehouses, indoor parking lot, such as the fine leveling of the ground at the grass-roots level, The thickness of a single construction can be up to 5m-25mm, at room temperature (above 25℃) and under the condition of good ventilation, it can be used in about 6 hours. The next process can be carried out after self-leveling and completely drying. It can shorten the construction period, provide smooth and sound, solid ideal base. All kinds of elastic floor, ceramic tile, wood floor, carpet, epoxy, polyurethane and other floor materials can be directly pasted on the finished floor.

Construction method

1、Cleaning up substrate, choose the appropriate primer, when the primer in the dry state (about 2-6 hours after the bottom coating), then begin self leveling operation.

2、Add 5L water in the mixing container, and then slowly add a pack of 25kg self-leveling, stir with a blender to uniform no group of pulp, pour out the mixture, evenly spread out, with a special toothed scraper to control the thickness, you can use the transport capacity of 20-40L/min pump slurry, mixture must be used in 20 minutes, prevent direct sunlight and strong wind blowing.

3、Before the initial coagulation, the use of special defoaming roll roll to exclude the air, to ensure uniform thickness.

Reference dosage

M625 cement based self leveling mortar layer thickness is about 3.5kg/㎡∙2mm,the specific amount is determined by the actual conditions and the thickness of the construction base.

Matters needing attention

As this product contains cement, it reacts with water to produce strong alkaline, and avoid contact with skin and eyes. Once in contact, flush immediately with water. If skin or eye is injured, seek medical attention immediately. This product is completely hardened and will not produce any material that affects the body or the environment.
