Performance

Product advantages

Fully elastic.
Creates waterproof covering without joint or juncture.
Offers long service time.
Easy to apply. Applicable with trowel, roller, brush or spraying machine.
Prevents carbonation on concrete.
Does not cause shrinking or cracking.
Highly resistant against chlorine ions.
Applicable on fresh screed and concrete surfaces due to its crack bridging property.
Allows the concrete to breathe due to its water vapour permeable structure.
Resistant to freeze-thaw cycle.
Nontoxic and noncorrosive.
Not affected by vibration and deformation due to its high elasticity.

Use guidance

From selection
to application.

Application

The mixture should be applied on the intended surface in a minimum of two layers. The first layer should be fully dry before the second and any additional layers are applied perpendicular to the previous application. Make sure layers are homogenous and smooth. Application should be in the same direction on each layer. Wait for at least 5-6 hours between layers depending on temperature. Total application thickness of 2-3 mm will be sufficient. Recommended to use waterproofing mesh or seal between layers in order to improve carrying capacity of product. After topcoat application, the surface can be smoothed by means of a dry sponge. After topcoat, substrates should be protected from direct sunlight, air circulation and frost for 3 days. The substrate should be wetted and kept damp if needed.
