Product Description
Product Description
Polar Bear cementitious self-leveling materials consist of a blend of selected cements, superplasticizer, and aggregates modified with polymers and flow agents. Polar Bear cementitious self-leveling materials are supplied as pre-blended powder which requires only the addition of water on site to produce a self smoothing, free flowing material. These materials are designed for installation by a continuous mixer pump, but can also be applied by hand.
Advantage
1. Fast application by pump, enables large areas of floor to be completed in a working day
2. Rapid hardening and curing allows speedy access for foot traffic, the 4h compressive strength can be above 10.0Mpa.
3. One pack product, applied by pump eliminates on-site batching and ensures consistency of mixed product
4. Dimensionally stable, can be installed in large areas
5. Excellent adhesion to prepared substrates, the bonding strength can reach 2.9Mpa in 28d age.
6. Environmental friendly.
Uses
1. As an self leveling floor for the concrete surface (indoor or outdoor).
2. Repair works for the concrete surface.
3. Reinforcement for the concrete structure
4. Grouting works for bolt holes, secondary pouring in the equipment installation.
5. Urgent repair and build in concrete projects.
Application Instructions
Preparation
1. The substrate should be clean, sound and free from loose material and contamination such as plaster, oil, paint and grease. The substrate should have a compressive strength of at least 15MPa and a surface tensile strength of at least 1MPa (pull-off strength).
2. Excess laitance should be removed by mechanical methods followed by vacuuming and water cleaning to remove dust debris.
3. Oil and grease can be removed by chemical detergent followed by water cleaning.
4. New concrete should be at least 14 days old.
5. In case of porous substrate or hot weather, the substrate should be ponded with clean water for 1~3 hours before priming.
Priming
The object of priming is to seal the substrate to prevent air release from the subfloor rising and forming bubbles and pinholes on the surface. Extremely porous substrates may require two priming/sealing coats. Primer coats must be allowed to dry before applying the self-leveling material.
Pumping or mixing by hand
1. This is a specialized activity and the product must be applied by a recommended contractor who has been fully trained in the use of the product and equipment.
2. In case of installation by hand, pour the mixing water into the clean mixing vessel. Add the whole bag of powder slowly to the water, mixing continuously with a heavy duty drill fitted with a suitable paddle. Mixing should continue for at least 3 - 5 minutes
3. Whatever pumping or mixing by hand, make sure that a smooth creamy consistency is obtained.
4. Do not mix more material than can be reasonably laid within the flow time of the material. However, ensure that subsequent mixes are ready to enable continuous pouring.
Pouring
1. Make sure there is no ponding of primer before pouring the material.
2. Pump should be used for large area application.
3. Pour the mixed material on to the dry primed surface, spread with trowel and allow self-smoothing. Roll surface with the purpose made spiked roller. Best results are achieved when the pouring and leveling is a continuous process.
Cleaning
The material should be removed from tools and equipment with clean water immediately after use. Hardened material can only be removed mechanically.
Storage
Polar Bear self-levelling material should be stored on pallets in dry conditions. Under these conditions the product will have a shelf-life of 6 months.
