Sovacryl

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.

Application

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

Features

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

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.

Uses

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

Substrate

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.
