Polymer Modified Cement-Based Thin Base Coat

Product Group:

Skim Coat & Render System

POLYMiX Fine Mortar Base is a high-quality, polymer-modified, water-resistant cement-based thin base coat specially formulated for direct application onto porous concrete, concrete panels, and plastered surfaces for patching and surface leveling works. It is highly recommended for all internal applications.
Appearance: Grey and white
Adhesion to concrete (28 days): Approx. 0.6 N/mm² (lab condition)
Pot life: 1 hour
Coverage: Approx. 1.3 kg/m²/mm
Recommended Thickness: 2-4mm/build-up/application
Binder: Portland Cement
Filler: Calcium Carbonate Powder/dry graded silica >95% SIO2
Additives: Water-soluble polymers
Properties: Improve consistency, workability, water retention & adhesion
Remove all loose materials or traces of foreign materials and ensure the surface is clean, free of dust and dirt. It is recommended to damp the substrate surface prior to the application of POLYMiX Fine Mortar Base.
Mix thoroughly a bag of 40kg POLYMiX Fine Mortar Base with 11.0-12.0 liters of clean water by using an electrical power mixer for 3 to 5 minutes until a homogeneous paste is achieved. Re-mix the material before re-use if the material is left undisturbed for more than 30 minutes.  
Apply freshly mixed POLYMiX Fine Mortar Base with a steel trowel or spray machine to profile the substrate surface to an average thickness of 2 to 4mm. If application requires more than a single coat, continue to trowel POLYMiX Fine Mortar Base and allow the underlying coat to gain partial curing before applying the subsequent coat to achieve the desired flatness. POLYMiX Plaster Finish can then be applied onto POLYMiX Fine Mortar Base if extra smooth finishing is required.
Packing: 40kg/bag
Shelf life: 6 months
Storage: Keep in cool dry condition
  • Precautions!
  • Clean tools with water before the product dries.
  • Do not apply to extremely absorbent substrate without prior pre-wetting. In hot conditions, protect the 1 surface from drying out rapidly by lightly misting to prevent powderiness.  
  • Do not mix the product with OPC/white cement/lime.
  • Do not apply thinner than the minimum recommended thickness of 2.0mm.
  • It is a good practice not to exceed the recommended thickness/build-up and at a minimum of 2 coats and leave for initial set before applying the subsequent build-up.
  • Do not apply when there is vigorous hacking activity in the vicinity of the application area.
