Skim Coat & Render System

POLYMiX Thin Plaster is a high quality polymer modified water-resistant cement-based thin plaster specially formulated for direct single product application onto concrete and plastered surfaces for patching and surface levelling & smoothening works. POLYMiX Thin Plaster is also designed as a fairing coat onto POLYMiX Render and PolyCrete Repair Mortar surfaces. It is suitable for internal applications only and not recommended to be applied onto painted surfaces and all cured smoothened cement-based finish surface.

Properties : Improved consistency, workability, water retention & adhesion
Remove all loose materials or traces of foreign materials and ensure surface cleaned, free of dust and dirt. It is recommended to damp the substrate surface prior to the application of POLYMiX Thin Plaster. All pinholes on substrate should be patched up with POLYMiX Fine Mortar Base prior to application.
Mix thoroughly a bag of 40kg POLYMiX Thin Plaster with 13.0-14.0 litres of clean water by using an electrical power mixer for 3 to 5 minutes until the 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 Thin Plaster with steel trowel or spray machine to profile the substrate surface to an average thickness of 1 to 2mm. If application requires more than a single layer, continue to trowel POLYMiX Thin Plaster and to allow the underlying layer to gain partial curing before applying the subsequent layer to achieve the desired flatness and smoothness, and is recommended to be applied in 2 coats.
Packing : 40kg/bag
Shelf life : 6 months
Storage Keep in cool dry condition
  • Temperature range for use 10°C-40°C 
  • Clean tools with water before the product dries
  • Do not apply to extremely absorbent substrate without prior pre-wetting. In hot conditions, protect the finish 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 1.0mm.
  • Mechanical or manual sanding with any sand paper are strictly prohibited. Sanding will loosen the cohesion and thereby causes powderiness.
  • Do not apply when there is vigorous hacking activities in the vicinity of the application area
