M625 Cementitious thick layer self-leveling
M625 Cement base thick layer self leveling mortar，With the special cement, fine aggregate, polymer resin and other additives of cement powder spray, the product has good mobility , can fast automatic leveling the ground, a construction thickness of up to 5-25mm at room temperature, can walk after 6 hours, When the self leveling is completely dried, the next process can be carried out, shorten the construction period, can be directly in the ground paving tile, wood flooring, carpet, flooring and other materials to provide all kinds of elastic ground leveling intact, solid ideal base, non-toxic and harmless, green environmental protection products.
Features：
Construction thickness of up to 5-25mm;
With good construction;
Quick leveling, high strength;
Low shrinkage, no cracking.
Applicable substrate:
Apply to factories, warehouses, parking lots, hospitals, operation room, family, office and other ground engineering level leveling.
Substrate Preparation:
The base must be dry, firm, load-bearing, dust-free, and free from impurities. In order to ensure the self-leveling surface strength and adhesion, M318/M320 is recommend for absorbent /non-absorbent substrate.
Construction method:
① After cleaning up the grassroots, should choose the appropriate interface agent, when the interface agent in the semi dry state (about 2-6 hours after the bottom coating construction), began to self leveling construction.
②In a container of water poured into the 5L, then slowly add a bag of 25kg self leveling, stirring for 2-3 minutes to uniform group slurry mixer, the mixture is poured, evenly spread, with a spatula to exhibit uniform required thickness, good construction mixture just to prevent direct sunlight by the sun and the wind blowing, The mixture must be completed as soon as possible. The self leveling of the rigid construction should prevent direct sunlight and strong wind blowing. The slurry can be conveyed with a pump capacity (20-40 L / min).
③Before 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/m² ·2mm,the specific amount is determined by the actual conditions and the thickness of the construction base.
