Polypoxy
Polypoxy
Epoxy resin based chemical and abrasion resistant screed
Properties
- High Impact and abrasion resistance
- High compressive, flexural and tensile strength
- Good resistance to chemicals
- Non shrink
- Non tainting
- Solvent free
Description
Polypoxy is a solvent free, non-shrink, epoxy resin based mortar screed. The epoxy screed has excellent mechanical and abrasion resistance properties and is resistant to a wide variety of chemicals. This system is designed to provide a heavy duty topping for industrial floors. The screed can be applied in thicknesses from 4mm to 20mm in a single lay.

- Step by Step
Surface preparation
Clean the surface of all dust, dirt, oil & grease, cement laitance and all loosely adhering particles. New concrete surface shall be at least 28 days old and the surface moisture content less than 5%. Captive/grit blasting and grinding is recommended for the most effective surface preparation. Surface irregularities and blow holes shall be repaired with Polypoxy BF* (Epoxy resin based blow hole filler and skimming mortar) or Ceresit RS 88* (cementitious repair mortar). Alternatively an epoxy resin based scratch coat can be used when repairing larger areas (> 0.5m2). The surface after carrying out the necessary cleaning shall be vacuumed for removing the dust debris left over after the cleaning process.
Priming
The surface shall be primed with a solvent free epoxy primer (Polyprime EP*) @ 4-5 m2/L.
Mixing
Mix part A and B separately for 2 minutes using a heavy duty slow speed drill (300-400rpm) fitted with a spiral mixing paddle. Pour Part B (hardener) and Part A (base) into a separate container and mix well for a few minutes. Add Part C (filler) slowly to the mixed base and hardener and continue mixing for further 3 – 5 minutes until a uniform and homogenous lump free consistency is achieved. As the products are supplied in pre-weighed packs, part mixing is not at all recommended, as the cured product will not achieve its full properties even if there is a small variation in the mixing proportions.
Application
The epoxy screed shall be applied immediately after mixing within its working time. Discharge the mixed mortar from the mixer and place on the floor when the primer is still in a tacky condition. Spread and compact the mortar with a wooden trowel to get a uniform thickness and complete the application with a steel trowel.
