ISOMAT ISOFLEX Waterproofing membrane for flat roofs and tiled roofs redbrown 5kg

ISOFLEX is an elastomeric, water-based, 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 conditions and

aging.

• High whiteness and solar reflectance.

• Improvement of building energy efficiency by

decreasing the roof temperature.

The white is certified as cool paint.

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

waterproofing solution for roof details, such as

corners, edges and joints between different

adjacent materials, as well as for 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

(30 g/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.

The technical information and instructions supplied in this datasheet are based on the knowledge and experience of the Research and

Development Department of our company and on results from long-term applications of the product in practice. The recommendations and

suggestions referring to the use of the product are provided without guarantee, since site conditions during the applications are beyond the

control of our company. Therefore the user is responsible for confirming that the chosen product is suitable for the envisaged application. The

present edition of this technical datasheet automatically cancels any previous one concerning the same product. | Edition: 23.04.2024

Subsequently, two extra layers of ISOFLEX are

applied over the entire surface.

Consumption: approx. 1.5 kg/m2

, depending on the

substrate.

In case there are dense, multiple cracks all over

the surface, it is strongly recommended to fully

reinforce ISOFLEX membrane with 100 cm wide

strips of fiberglass mesh (65 g/m2

) or polyester

fleece (30 g/m2

). These placed strips must overlap

by 5-10 cm.

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: 2.0-2.5 kg/m2

, depending on the

substrate and 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: 200-250 g/m of crack length.

Tools should be cleaned with water while ISOFLEX

is still fresh.

Packaging

ISOFLEX is supplied in plastic containers of 1 kg,

5 kg, 13 kg and 25 kg.

Shelf life – Storage

24 months from production date if stored in

original, unopened packaging at temperatures
