Flexible acrylic waterproofing system

Sovacryl is a premixed flexible acrylic waterproofing membrane that can be applied directly from the pail. This product can be used as a 5-layer or 3-layer system.

Sovarcryl Zoom


Generally, Sovacryl membrane is applied using a brush or roller. Due to its elastomeric quality, it may not be possible to get a flat, level finish and brush or roller marks are common. Apply the first coat in one direction and the second coat in a perpendicular direction to the first coat.

Sovacryl 5-layer System

Sovacryl 5-layer fabric reinforced waterproofing system is designed to overcome unevenness of a roof surface by building up the waterproofing membrane thickness. This system is suitable for positive waterproofing of concrete flat roofs in areas with light foot traffic.

Fields of Application

  • Waterproofing of old and new roofs
  • Refurbishment of old concrete roofs and concrete gutters


  • Easy to apply
  • High polymer paste form
  • Mould and fungus resistant
  • Bridges cracks and remains flexible
  • Resistant to ultra violet rays
  • Water-based and non-toxic
  • Available in various colours

(Further information available on the data sheet)

Sovacryl 3-layer System

Sovacryl 3-layer system forms a microporous membrane that waterproofs external surfaces from water seepage and protects it
from deterioration due to carbonation, acid or chemical attack and
other types of environmental pollution.


  • Waterproofing of external walls of old buildings, metal roofs,
    gutters and asbestos roofs
  • Waterproofing of old roof tiles


All surfaces to be waterproofed must be sound. Jet washing or
mechanical abrading is recommended to increase adhesion if
applied on existing surfaces. Old coatings which are stable and
cannot be removed, can remain.
