產品描述

Polar Bear cementitious self-levelling materials consist of a blend of selected cements, superplasticizer, and aggregates modified with polymers and flow agents. It is used in conjunction with Polar Bear Primer. Polar Bear cementitious self-levelling 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.
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 20MPa 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-levelling 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.
