ISOMAT ISOFLEX WATERPROOFING FOR ROOFS

ISOFLEX is an elastomeric, waterborne, liquid waterproofing membrane for flat roofs. Has
excellent bonding to various substrates, such as concrete, wood, metal and any type of
waterproofing membranes and is applicable even to irregular substrates. After curing, it forms a
continuous, elastic, waterproof and vaporpermeable membrane, without seams or joints, offering:
 High elasticity.
 High resistance to weather and aging.
 High whiteness and solar reflectance.
 Improvement of building energy efficiency by
decreasing the roof temperature.
Certified according to EN 1504-2 and classified as
a coating for surface protection of concrete. CE marked. Certificate No.: 2032-CPR-10.11.

Fields of application
ISOFLEX is ideal for waterproofing flat roofs, curved roofs, etc. Constitutes a simple and safe
solution for waterproofing roof details, such as corners, edges and joints between different
adjacent materials, as well as isolated cracks. Furthermore, thanks to its high solar reflectance, it
can be used as cool roof paint.

Directions for use
1. Substrate preparation
The substrate must be dry, clean, free of grease,
loose particles, dust, etc. Any existing cavities in
concrete should be filled in advance. The substrate
can be primed with the special primer ISOPRIMER with a consumption of approx. 200 g/m2.

2. Application
a) Full-surface waterproofing
ISOFLEX is applied by brush or roller in two layers,
after the primer has dried. The second layer should
be applied crosswise after the first one has dried.
In areas with severe cracks, it is recommended to
reinforce ISOFLEX with a 10 cm wide strip of fiberglass mesh (65 g/m2) or polyester fleece (30g/m2) along the cracks. In that case, after the
primer has dried, the first layer of ISOFLEX is applied along the cracks and, while still fresh, the 10 cm wide strip of fiberglass mesh or polyester
fleece is embedded lengthwise

Subsequently, two extra layers of ISOFLEX are applied over the entire surface.
Consumption: approx. 1.5 kg/m2, depending on the substrate.
In case of dense, multiple cracks appearing all over the surface, it is strongly recommended to
fully reinforce ISOFLEX membrane with 100cm wide strips of fiberglass mesh (65 g/m2) or polyester fleece (30 g/m2). These placed strips
must overlap by 5-10cm.

After the primer has dried, a first layer of ISOFLEX is applied to a width of 100 cm (as wide as the
upcoming reinforcement), and, while still fresh, a strip of fiberglass mesh or polyester fleece is
embedded. The same application process is followed until the remaining surface is covered.
Subsequently, two extra layers of ISOFLEX are applied over the entire surface.
Consumption: approximately 2.0-2.5 kg/m2, depending on the substrate and the type of
reinforcement.

b) Local waterproofing of cracks In this case, the primer is applied on the substrate
only along the cracks to a width of 10-12 cm. After the primer has dried, the first ISOFLEX layer is
applied and, while still fresh, a 10 cm wide strip of fiberglass mesh (65 g/m2) or polyester fleece
(30 g/m2) is embedded lengthwise. Subsequently, two extra ISOFLEX layers are
applied along the cracks, completely covering the reinforcement.
Consumption: approximately 200-250 g/m of crack length.
Tools should be cleaned with water, while ISOFLEX is still fresh.


Shelf life – Storage
24 months from production date if stored in
original, unopened packaging at temperatures
between +5°C and +35°C. Protect from direct
sunlight and frost.
