Arkimix ACR

Versatile polymer latex for cementitious mixes used in plastering (rendering), floor screeds, and external rendering.

Arkimix ACR is a copolymer emulsion designed to act as an modifier for cementitious mixes used in plastering (rendering), floor screeds, and external rendering to improve mechanical properties and enhance water resistance.

Uses

  • Used as a modifier for cementitious plaster (rendering).
  • Suitable for floor screeds.
  • Ideal for cementitious external rendering.
  • Improves the water resistance of cementitious mixes.
  • Enhances the performance of cementitious applications.

Advantages

  • Increased durability and toughness.
  • High resistance to water penetration.
  • Accelerated early-stage hardening.
  • Improved tensile and flexural properties.
  • Reduced shrinkage.
  • Good resistance to abrasion and wear.
  • Reduced bleeding (water segregation) in concrete.
  • Improved bond strength to surfaces.

Usage Instructions

Follow each step for best results.

01 Surface Preparation
Use fresh cement and well-graded aggregates that are free from excess fines. Ensure that all materials are compatible with the intended application and meet the required design standards.
It is preferred to use a pan mixer. Manual mixing is allowed when the total weight of the mix is less than 25 kg. Add the required quantity of sand and cement to the mixer, then add Arkimix ACR and mix for 2 minutes, then gradually add water until the desired consistency is achieved.
Apply the modified plaster (render), floor screed, or external rendering using standard application techniques. Avoid using excessive water, as modified mixes may appear more workable than they actually are. Do not over-trowel or over-work the surface.
Clean all tools and equipment with water before the material dries and hardens. Hardened material can only be removed mechanically.
