Be aware that in 2012
Queensland Building Services with the support of major building contractors,
will be cracking down on waterproof membrane quality – more precisely, the dry
film thickness (DFT) of applied liquid waterproof membranes.
Take responsibility and
be pro-active -
Know your product data – Chemind Data Sheets give minimum DFT as well as Preparation
and Application information.
Use appropriate equipment – Chemind has suitable brushes
○ Water Based (Newflex WAM Fibre) – use a 32mm nap roller
○ Polyurethane (Aquagard M Zero VOC Grey) – use a 22mm
Check wet film thickness (WFT) regularly – as a guide:
○ Water Based (e.g. Newflex WAM Fibre) – 1 litre/m² = 1mm
WFT = 0.6mm DFT
○ Polyurethane (e.g. Aquagard M Zero VOC Grey) – 1
litre/m² = 1mm WFT = 1.0mm DFT
Do not be coerced into performing substandard work -
If directed to performing work that does not comply with
Australian Standards or manufacturer’s instructions, protect yourself. It is
your right and responsibility to notify the builder by issuing a
Non-Conformance Report (NCR) and stating that any works performed will not be warranted.
Final DFT is simply a
matter of the quantity of product used. All manufacturers make recommendations
for required thickness.
QBSA inspectors may
remove samples from site and have them scientifically evaluated to verify that
the product complies with manufacturer’s requirements.
In recent years CHEMIND R&D has developed high
performance, high quality polyurethanes under the Aquagard M banner. These new generation waterproofing elastomers are
fully compliant with AS3740, AS/NZS4858 and AS4654.
Aquagard M polyurethane with confidence – these membranes have:
high % volume solids and certainty of drying
best value per mm DFT – cheaper than any
water-based membrane for equivalent DFT
proven long life and in-service durability
safe to use internally with the unique Chemind Aquagard M Zero VOC
