Advantages & Benefits

High level airtight properties.
Highly flexibility and has an ability to re-form against differential movements.
Cures and hardens without cracking.
Outstanding Adhesion
Excellent value for money
Excellent workability.
Impervious to water.
Permeable to water vapour.
It can be applied with a brush, paintbrush or roller.

Instruction for Use

Knead ARGOTEC HERMETIC with the appropriate amount of water to achieve the optimum consistency (homogeneous, creamy, lump-free mixture with a thick paint-like appearance). The kneaded mortar should always be applied in a minimum of two coats so that a homogeneous coating is obtained.
Apply the first layer of mortar with a brush, pressing on the substrate to ensure adherence in thicknesses of less than 2 mm, trying to ensure that the mortar covers the entire surface. The following coats shall be applied by brush or airless machine and in perpendicular directions once the previous coat has dried (4-24 h depending on environmental conditions)”.
