Description:
At 350% elongation, Aussietex III is classified as a "Class III Membrane" (high extensibility) within the new AS 3740-2004 "Waterproofing of wet areas within the residential buildings". Under the Standard, the more a membrane stretches without tearing, or bends without breaking when subjected to joint movement, the better it is suited to waterproofing, especially when used in conjunction with the appropriate bond breaker type and application. Aussietex III should only be applied by a fully trained operator.

Characteristics:
  1. 1:1 (volume) mix ratio.
  2. LOW PRESSURE plural component equipment is required to apply Aussietex III.
  3. 100% solids and exceptionally low V.O.C’s.
  4. Fast build to required thickness (reduces labour and time).
  5. Fast Tack Free Time (TFT) of 2 minutes.
  6. Fast curing for quick turn around times(can walk on after 30 minutes).
  7. Excellent resistance to long term exposure to moisture.
  8. Will not corrode.
  9. Resistance to mould and fungal growth.
  10. Good abraision resistance and toughness.
  11. Bonds to most substrates when the appropriate surface preparation and recommended primers are used.
  12. Long term retention of flexibility.
  13. Although Aussitex III is resistant to UV and weathering some colours may change more than others with exposure. (Rate of colour change depends on application thickness, choice of colour, addition of aggregate into top coat and exposure to UV).

Surface Preparation:

  1. Concrete: ~ Surface should be clean and slightly rough. Prime with a single coat of 100WB.
  2. Aluminium: ~ Degrease. Abraisive grit to blast to Class 2½ blast.

Adhering Tiles and Carpets:
Tiles, artificial grass, paints and other coatings may be applied over Aussietex III. Advice needs to be obtained.

  1. Tiles ~ Several companies have tested and approved the use of their adhesives for adhering to Aussietex III for use in waterproofing applications. It is important that applicators carry out work to AS 3958 Part 1, 1991.
  2. Adhering Artificial Grass and Outdoor Carpet ~ Several companies have tested and approved the use of their artificial grass adhesive over Aussietex III.

Application Thickness:
Minimum coating thickness of 1.0mm is recommended. Several millimeters can be achieved very quickly by allowing 50-60 seconds to elapse between passes.

Abrasive coatings ~ Light to Heavy Duty 4mm - 7mm
Corrosion protection 1.5mm - 3mm
Waterproofing ~ Standard Duty 1mm - 2mm

Uses:
Aussietex III may be used in many application some of which are ...

  • Waterproofing Membrane
  • Protective Coatings
  • Corrosion Resistance
  • Electrical Insulation
  • Sound Control
  • Abrasion Resistance

Equipment Used For Application:
Use low-pressure spray equipment. Pre-heating the containers before use in colder weather will improve the finished quality of the membrane. Only applicators trained in the use of this machinery should be allowed to apply Aussietex III.

Cure Details:
The cure rate of this product is dependant on the ambient and surface temperatures.

Storage & Processing Characteristics:
  • Store in original containers, tightly sealed, until required. (Urethane components suffer from moisture contamination).
  • Don't leave Part A for extended periods in the processing equipment. Replace it with LiquiLube.
  • Store containers above 15°C to maintain them in good condition.
  • For best results ore-condition containers to 30°C.
  • The substrate should be at least 20°C or hotter for best application results.
