Description:
Aussietex II is a two component
flexible cementitious waterproof membrane ideal for use in internal
wet areas. Aussietex II provides
toughness and tensile strength through the employment of integral fibre
reinforcement. Advanced acrylic polymers combined with cements and special
fine fillers achieve an excellent flexible waterproof membrane barrier
particularly suited for under tiles in internal locations.

Application Directions:
Substrate preparation
The surface must be clean and sound, free of dust, loose particles, cement
laitance, grease, rust, sawdust, paint and mortar droppings. All wall
and flooring boards must be fixed as per manufacturer’s instructions.
Drainage needs to be provided and locations of constant water exposure
(e.g. shower stalls) and falls in the order of 15mm per 1m should be provided.
All connecting building parts of different materials, construction joints
and cracks, wall and floor junctions, drainage outlets, door to sill on
slider doors, internal and external corners, allow the Aussietex
II to accommodate movement by filling the joint with polyurethane
sealant before applying the Aussietex II.
Priming
Apply 1 coat of Hi-Tek WB to a clean substrate by roller or brush at 7
to 10m² per litre depending on substrate. Allow Hi-Tek WB to dry
before application of Aussietex II.
(Approximately 15 to 30 minutes depending on temperature and porosity
of substrate).
Mixing
Leave part A (liquid) in mixing bucket and gradually add part B (powder)
while using an electric drill/mixer equipped with a grout-mixing paddle.
Mix for 5 minutes and until a homogeneous and lump free consistency is
achieved. Allow to stand for 5 minutes, and then restir before use. Do
not change mixing proportions nor add water.
Application
Aussietex II can be applied with
roller, squeegee, brush or trowel. For large areas it may be sprayed using
a suitable worm type mixer/pump. Apply at least 2 coats of Aussietex
II with an average thickness of 1mm WFT each. Apply evenly
to the surface achieving a continuous film allowing the first coat to
dry before application of second coat. Ensure the system terminates correctly
under flashings if being turned up and down into the floor wastes or drainage
outlets. A one coat prestripe is recommended over cracks, wall floor intersections,
down into drainage wastes etc as these locations are where movement is
to be expected in service.
NB. Do not apply externally if rain is anticipated
within 2 hours.
Estimating Data:
The consumption of Aussietex II
depends on substrate smoothness and requirements, however as a guide:
| Waterproofing |
2litres/m² |
| Yield per kit is |
18 litres |
Coverage of mixed kit is 9m² based on 2 applications at 1mm WFT
with cured thickness of 1.5mm to 1.6mm.
Hi-Tek WB (as a primer)
As a guide: 7-10m²/L
Curing:
Curing depends on the ambient temperature; however as a guide Aussietex
II becomes firm touch dry after 2 hours curing at 23ºC.
Full cure is achieved after approx. 7 days. In locations where the membrane
is thick (e.g. corners) and/or applied over sealant curing will be slowed
down.
Homogeneous hardening and waterproofing are only achieved when too rapid
drying out is avoided. Protect fresh coats against exposure to strong
wind and direct sunlight. Once dry, Aussietex II
needs no additional after treatment and is ready for tiling over.
Cleaning:
Tools should be cleaned with water before the Aussietex
II hardens.
Shelf Life:
When stored in the cool and dry. Aussietex II
can be stored for 12 months in tightly closed original containers. Do
not allow Part A to freeze. Once frozen, Part A becomes unusable.
Packaging:
Available in 40kg kit comprising:
Precautions:
Ausietex II is non-toxic,
but as with other product containing Portland cement, it has an alkaline
nature and thus can be irritating to skin and eyes. Wear dust masks, goggles
and gloves when handling. Wash off splashes of material with clean water.
If irritation persists, seek medical advice. For full safety and first
aid instructions, refer to the product Material
Safety Data Sheets. |
