Application

For professional use in domestic, commercial and industrial applications, such as street furniture, terraces and balconies, swimming pools and fountains, saunas and spas.

Description

Eco-friendly, inorganic mineral adhesive with a low chemical additive content for high performance bonding with no vertical slip and long open time. For use on porcelain tiles, ceramic tiles and natural stone.

Features and benefits:

  • Suitable for internal and external use on walls and floors.
  • Mineral bentonite: Bioflex® contains mineral bentonite which, on contact with the mixing water, transforms into a highly thixotropic adhesive, maintaining shape and thickness under the tile and guaranteeing smooth spreading.
  • Natural NHL lime: Bioflex® contains mineral cement improved with natural NHL lime, which gives the mix greater plasticity and slide. It prevents thickening in the bucket and reduces the use of chemical additives.
  • Plant latex: Bioflex® contains ingredients of plant origin that improve workability and open time. It has a low chemical additive content and does not emit dangerous substances or unpleasant odours.
  • High and low thickness.
  • EMICODE® Green Building rating: Grey: Eco 4; white: Eco 5.
  • CE marked to BS EN 12004, and contributes to LEED points.
  • ISO/ TS 14067 compliant.
