Water resistant self leveling mortar
Water resistant self leveling mortar is the research and development achievement of the "Twelfth Five Year Plan" national science and technology support project "Research on Modification and Application Technology of Ground Self leveling Materials" undertaken by our company.
Water resistant self leveling mortar is composed of cementitious component of ternary system, ultra-fine inorganic filler The prefabricated dry powder processed with a variety of polymer modifiers and multi-stage aggregate can be mixed with water to form a high fluidity slurry, which can be automatically leveled and hardened quickly. You can walk on it or carry out subsequent works in three hours. Effectively solve problems such as uneven ground, difficult leveling, and ground dusting.
Scope of application:
It can be used for the floors of industrial plants, workshops, warehouses, commercial stores, exhibition halls, stadiums, hospitals, stations, squares and other open spaces, as well as the floors of offices, homes, villas, warm small spaces, etc. Accurate leveling and surface laying board Save labor and time.
Superior performance:
1. Good fluidity, easy construction and automatic and accurate leveling.
2. Due to the introduction of ultra-fine suspending agent and thickening component, the product will not segregate and bleed, and has good cohesiveness, smoothness and no hollowing.
3. It has good impermeability, has hydrophobic groups, and is reasonably graded. The hardened body is compact in structure, effectively preventing water infiltration and migration.
4. Of Special adhesive The ordinary silicate gelling system modified by the gelling component is water resistant, non shrinking and anti cracking.
5. People can walk after 3-4 hours; Light traffic can be opened after 24 hours.
6. The elevation is not increased, and the ground layer is thinner up to 2-5mm, saving materials and reducing costs.
7. It is safe, beautiful and pure to use. It has promoted civilized construction, created a high-quality, comfortable and flat space, and paved diversified and beautiful decorative materials, adding gorgeous colors to life.
Construction process:
1. Clear the sundries on the base course, and the base course must be free of cracks, solid, clean, flat, oil stains and other foreign matters. Brush after cleaning roller Brush the interface agent.
2. Add 4.7kg of water to each 25kg bag, and stir for five minutes until there is no caked viscous paste.
3. Mechanical pouring or manual construction shall be adopted, and hanging paving shall be assisted at corners.
4. Let it stand for 5 minutes to fully eliminate bubbles, then wear spiked shoes and use a defoaming roller to fully defoaming.
5. After the slurry hardens, it shall be immediately watered for curing for 1 day. The cushion shall be fully cured, and the surface course shall be sprayed with sealing curing agent and polished as required.
