Product Information

SUPERSEAL Plaster Base Membrane is fastened with plaster plugs on a 12" x 12" grid with perimeter ventilation strips. This system provides plaster and mud coats protection from moisture in underlying walls. The dimples provide a continuous ventilation air gap to dry out surface moisture or drain off water inflow. The plastic mesh ensures efficient bonding of the render or plaster coat.

SUPERSEAL Plaster Base Membrane creates healthy environments by way of the vertical air chamber created by the dimples in the membrane. The air chamber allows moisture to evaporate or drain off, not affecting the wall finish or the interior environment. SUPERSEAL Plaster Base Membrane is the ideal solution in all rooms in contact with the soil (cellars, garages, etc.) and in rooms above earth with rising humidity

Product Applications

SUPERSEAL Plaster Base Membrane is a specialty dimpled sheet used adjacent to damp walls to control moisture and allow resurfacing of above and below-ground structures. It is most commonly used for remediation of leaking commercial block walls, basement walls, tunnel arches, underground wine cellars or any surface requiring ventilation and drainage of damp interior walls.

Product Advantages

  • The integrated mesh provides an excellent bonding surface for plasters, render coats, spray-on foam and gunite, up to 1" (25 mm) thick
  • Optimum isolation of damp rooms
  • Ensures continuous air circulation and permanent dampness control in walls
  • Keeps plaster dry
  • Wide and easy to handle rolls result in rapid and low cost installation
  • Has an excellent chemical-biological resistance rating, is impervious to root penetration, rot-proof and unaffected by soil bacteria and fungi
