USES

As a protective decorative and waterproofing coating for concrete, mortar, brick and stone facades.

FEATURES/BENEFITS

- Highly flexible & durable
- Self cleaning, low dirt retention - Resists fungi & algae growth
- Large range of durable colours.
- Vapour permeable (allows facade substrate to breath).
- Prevents chloride ion, sulfide ion and carbon dioxide attack.

ADVANTAGES

- Fibre reinforced: Excellent strength, eliminates need for reinforcing mat.
- Flexible: Accommodates normal building movement.
- Advanced acrylic: Will not re-emulsify.
- Designed for tiling: Fully compatible with CLI- tile system adhesives.
- Water based, low odour and easy cleaning for undertile waterproofing in shower recesses.
- Conforms to the requirements of AS/NZ 4858:2004 Wet Area Membranes (Ref: CSIRO Report 3879).
*Critical areas include areas where the membrane is applied at greater than 0.5mm or over impermeable substances such as over bond breakers or incorporating other reinforcement. Longer drying times are necessary in these areas.

SUBSTRATE PREPARATION

Exposed concrete without old coatings:
The surface must be clean, sound, dry and free from loose or friable particles. Suitable preparation methods are steam, high pressure water jetting or blastcleaning.

Exposed concrete with old coating:
Old coatings must be tested for their adequate adhesion to the substrate - adhesion test average > 0.8 N/mm with no single value below 0.5 N/mm .

If there is inadequate adhesion then:
- Old coatings must be completely removed by suitable methods and the substrate must be sufficiently sound and prepared before coating.

If there is adequate adhesion then:
- Thorough cleaning of all surfaces is required, by steam cleaning or high pressure water jetting.

MIXING

For normal usage, CLI – AQUA SEAL is supplied ready for use. Stir thoroughly prior to application. For use on very absorbent substrates, add up to a maximum of 10% water stir well prior to use.

APPLICATION METHOD / TOOLS

CLI - AQUA SEAL can be applied by brush, short pile roller or airless spray. The second coat should be applied in a cross wise direction to achieve optimum opacity.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
