The technology of Duram Multithane Jointing Compound
comprises of two elements being the Multithane Std waterproofing membrane and a
curative compound which allows the Multithane Std waterproofing membrane to
fully cure in confined areas at significant thicknesses.
This data sheet should be read in conjunction with
Multithane Std data sheet.
Duram Multithane Jointing Compound therefore has the
advantages of a high performance waterproofing membrane in a pourable
consistency with the through-cure of a two pack system.
Multithane Jointing Compound cures to form a tough,
flexible, seamless jointing compound that bonds firmly to most substrates
(preferably primed) and is capable of withstanding normal structural and
thermal movement and hydrostatic pressure.
Advantages & Benefits
Multithane Jointing Compound represents the highest
standards in waterproofing technology and incorporates the following benefits:
Technology is based on a
proven CSIRO accredited waterproofing membrane.
Fast Curing - usually within
Suitable for permanent
immersion in water.
High strength and puncture
Resistant to a wide range of
pollutants, chemicals and detergents (excluding caustic and corrosive
Almost odourless when cured.
Formulated for long-term
Short-term UV exposure
High hydrostatic pressure
Can be used without primer on
suitable, low moisture content substrates.
Multithane Jointing Compound is ideal to seal and
Large open cracks
NB. This data sheet does not constitute a full
specification as site conditions and requirements vary. Confirmation of
suitability and specification should be sought from the Company regarding
Multithane Jointing Compound is suitable for use on most
sound and dry substrates, usually primed, including concrete, masonry, brick,
cement render or cement topping, fibre-cement board, plaster board, timber and
etch-primed metal. Substrates must be sound clean, and free of oil, grease,
release agents, adhesion reducing contaminates, anti-rust treatments and loose
or friable matter.
Additional information is also contained in Duram’s
General Preparation Guide.
Sound concrete, cement block-work, brick and masonry
substrates generally require no priming.
However, it is preferable to prime and all doubtful
surfaces should be primed.
Suitable primers are Duram Primeseal Duram Multiseal,
Duram Superprime 711 or Duram Primeseal SP.
Primeseal & Multiseal: Apply at 4 m2 per litre and
allow to cure.
Superprime 711 and Primeseal SP:
Apply at 8 m2 per litre and allow to cure.
Metal surface should be lightly abraided and metal etch
primed with Duram ME Primer or Duram Primeseal.
Multithane should be applied to the primed surface as
soon as possible after the primer is dry and within 24 hours. Beyond this
period the cross-linking diminishes. If membrane is not applied within 48 hours
the area should be re-primed.
Damp surface must be primed with Duram Primeseal. Freedom
from surface water and continual dampness is essential.
Add the Multithane Jointing Compound Curative to the
Multithane Std and thoroughly stir so that the curative is completely and
uniformly mixed throughout the product. Avoid air entrapment. Poor mixing will
result in poor and delayed curing and may negate or diminish the performance of
Multithane Std Curative

Insert a suitable backing rod and apply Multithane
Jointing Compound by pouring as required. Avoid over filling the joint and
allowance for the required space above the jointing compound must be allowed
for when under compression.
Whilst joints can be fully filled to virtually any depth
and width, the following should be considered:
For maximum elongation
capability the depth of the Multithane Jointing Compound should approximate but
not exceed half the width of the joint.
For non-porous substrates that
do not provide optimum adhesion such as aluminium, stainless steel or other
smooth surfaces the depth of the Multithane Jointing Compound should
approximate but not exceed half the width of the joint.
Multiple layers of backing rod
and Multithane Jointing Compound may be applied.
As a quide only, a 1000mm long x 10mm wide x 10mm high
joint will required approximately 1 litre of liquid Multithane Jointing
Compound before shrinkage.
Coverage is dependant upon type, porosity and of
substrate and backing rods material.
Multithane Std: 5 and 15 litre cans.
Curative: 300 grms & 900 gms
Avoid spills, as removal is difficult.
Risk is considered low when properly used but it is
important to observe precautions on the can and Material Safety Data Sheet.
Multithane Std is solvent based. The use of solvent
resistant rubber gloves and goggles (against splashes) is recommended.
