Properties
Zemdrain® MD self-adhesive is an addition to the range of
Zemdrain® controlled permeability formwork liners which
includes Zemdrain® MD.
„„ Zemdrain® MD self-adhesive is manufactured from
polypropylene.
Zemdrain® MD self-adhesive can be used with all formwork
but is particularly suited for special applications including:
„„ Upper surface (concrete face): smooth to slightly textured
filter fabric (PP)
For steel or plastic forms where stapling is very difficult or
impossible
„„ Rear side (form work): with special grid (PP) and
adhesive
„„ For formwork with specific geometrical shapes
„„ Adhesive type:PSA (*Pressure Sensitive Adhesive) made
of thermoplastic polymers
„„ For aesthetic concrete where staple marks are
unacceptable
„„ For small-sized formwork panels
„„ Seperating film: LDPE, with silicone coating on one side
„„ Multiple use: 2-3 times possible dependant upon handling
„„ High water/air storage volume, thus also suited for
inclined and horizontal surfaces

Quality convinces
The general requirements of the ‘Zemdrain® Application
Guidleines’ (version dated January 2011) remain applicable
for Zemdrain® MD self-adhesive. However, instructions
relating to tensioning and fixing using staples are now
superseded by the fixing instructions applicable only for
Zemdrain® MD self-adhesive.
Firmly fix in position by applying a uniform pressure to the
surface using a special roller
Concrete surface quality
Precise, computer-contolled application of the PSA-glue* on
the rear side of the formliner ensures that water draining
channels in the grid remain unimpeded. The glued surface is
covered with protective backing, which is simply removed
prior to the application; the formliner can thus simply be
glued to the formwork.
All test reports issued for Zemdrain® MD also apply for the
formliner Zemdrain® MD self-adhesive (except for test reports
and safety data sheets for drinking water applications).
Prior to using Zemdrain® MD self-adhesive please clarify all
technical details with our sales representatives or our
technical department. Phone 1300 737 787
During concreting water and air are drained as usual. Using
the well proven Zemdrain® formliner, the usual surface
concrete quality will thus be produced.
