Keratech® Eco Flex

Application

For the self-levelling correction of irregular and uneven substrates, with extra-rapid setting and drying, compensated shrinkage and very low Total Volatile Organic Compounds (TVOC's). For use in domestic, commercial and industrial applications and on heat-radiant slabs.

Description

A certified, extra-rapid hardening, eco-friendly, self-levelling mineral product for the high-performance and high-deformability correction of irregular substrates, suitable for use with EMICODE® Green Building. It has low CO2 emissions, very low volatile organic compound emissions and is recyclable as an inert material.

Keratech® Eco Flex develops a high degree of flexibility and dimensional stability, making it suitable to correct deformable substrates, providing high workability and hardness. It is a self-levelling product suitable for the subsequent laying of all types of coverings.

Features and benefits:

  • Suitable for internal use.
  • Thickness of 1–15 mm.
  • HDE technology included, with extended flow.
  • Suitable for laying ceramic tiles, porcelain tiles, natural stone and resilient materials using adhesives.
  • Suitable for laying hardwood floors using adhesives.
  • High dimensional stability and long-lasting performance.
  • Extra-rapid hardening.
  • High flexural strength with Advanced Flex Fiber™.
  • High mechanical resistance.
  • EMICODE® Green Building rating: Eco 4.
  • CE marked to BS EN 13813, contributes to LEED points.

Applications:

For the self-levelling correction of irregular and uneven substrates, with extra-rapid setting and drying, compensated shrinkage and very low Total Volatile Organic Compounds (TVOC's). For use in domestic, commercial and industrial applications and on heat-radiant slabs.
