Zemdrain® MD self-adhesive can be used with all formwork but is particularly suited for special applications including: For steel or plastic forms where stapling is very difficult or impossible „ For formwork with specific geometrical shapes „ For aesthetic concrete where staple marks are „ For small-sized formwork panels Keep material square on the form, remove protective backing, gently press the liner against the form 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. During concreting water and air are drained as usual. Using the well proven Zemdrain® formliner, the usual surface concrete quality will thus be produced.
