Duram Crystoflex 2 Part Cementitious Membrane

Recommended Primer:

1. Primeseal MC ( Moisture Cure)  2 Part Epoxy Primer for damp and existing membranes. 

Product Description

Crystoflex (Powder & Liquid Resin) Powder is the powder part of the two parts that make up Crystoflex. Crystoflex Powder is not a complete product and cannot be used on its own and should only used in conjunction with Crystoflex Liquid. Here follows information on Crystoflex, which is available under its own data sheet. Crystoflex is two part waterproofing membrane comprising of a liquid component of selected polymers and a powder component of selected cements, fillers and aggregates. When mixed together to form a brush-able or roll-able slurry, it provides a strong, hydrostatic pressure resistant, flexible waterproofing membrane. Crystoflex was formulated for immersed or ponding situations such as the waterproofing of water tanks and water features but is just as suitable for non-immersed applications such as roofs or under0tile waterproofing. Crystoflex complies with AS/NZS 4020:2002 Testing of Products For Use In Contact With Drinking Water – Australian Water Quality Centre Report Number 4007/92.1595.

Product Uses

Crystoflex is suitable for many waterproofing applications, but is particularly useful for areas requiring hydrostatic pressure resistance and immersed applications including:

• Water retaining structures such as concrete tanks, ponds, pools, fountains and water features.
• Crystoflex is suitable for contact with drinking water.
• Retaining walls, planter boxes.
• Roofs (top coated with Azcoflex TR or Azcothane as recommended).
• Under tile waterproofing on balconies, terraces, podiums and decks.

Product Benefits and Advantages

• Suitable for contact with drinking water.
• Meets the ‘Green Star’ environmental criteria.
• Very low VOC levels.
• Designed for applications where hydrostatic pressure resistance is required.
• Suitable for immersion in water.
• Two pack yet flexible.
• Quick drying.
• Can be applied to damp surfaces.
• Can be topped, tiled, or coated.
• Easy and safe to use.
• Compatible with most tile adhesives.
• Suitable for use in confined areas.
• Can be coated.
• Can be rendered with a polymer render or standard render with bonding additive.

• Crystoflex is flexible and can withstand normal building movement but it has limited elongation and hence will not tolerate
  excessive movement or cracking of the substrate. Cracks and gaps must be independently sealed and waterproofed.
• If the water is to be treated with chlorine, ensure that chlorine levels are maintained below swimming pool concentrations,
  recommended range 60-160PPM. High doses of chlorine may ‘burn’ and degrade the membrane.
