Description

Features:

  • RIW Cementflex, when mixed, exhibits a good degree of thixotropy to enable ease of application by brush or spray techniques to give an even finish with no sagging even in vertical situations.
  • It hydrates to form a durable, highly alkaline, permanently elastomeric coating which not only protects the concrete, or other substrates, from water penetration and carbon dioxide diffusion, but also accommodates movement in cracks.
  • The elastomeric coating maintains its flexibility under permanent immersion and when exposed externally.
  • Non-hazardous and ideally suited for application in confined spaces.
  • Must be applied to damp substrates.
  • Non-toxic when cured.
  • Applied by spray – brush or trowel applications can be employed but care must be taken to ensure that no air is trapped into the surface.
  • CE marked.

Substrate:

  • The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth.
  • The concrete sub-base should be a minimum of 20 N/ mm².

Application rate:

1.6 kg/mm/m².

Application temperature:

5–35°C.

Usage:

  • Suitable for waterproofing and protecting concrete and masonry structures which exhibit cracking, and where further movement is expected.
  • Typical applications include preventing water ingress into basements, cellars and other below ground structures.
  • Also suitable for waterproofing of exposed or buried roofs, and as a crack isolation membrane on concrete floors or screeds.
  • The coating is not a decorative finish and may temporarily discolour until uniformally weathered.
