- ATLAS GRAWIS U is produced as a dry mixture of the highest quality cement binder, aggregates and specially selected modifying additives.
- Flexible - has 3D reinforcement - fibres in the product provide additional dispersed reinforcement, thanks to which the mortar is protected against microcracks and has better mechanical resistance.
- Maximum adhesion after just 24 hours - adhesion to polystyrene foam after 24 hours (measured at + 20 °C) is a minimum of 0.08 MPa, and for concrete a minimum of 0.25 MPa and allows rapid commencement of additional fixing of thermal insulation with mechanical fasteners.
- Rapid strength gain - priming for plaster or studding can be started after:
- 24 hours, at a temperature of approx. +20 °C and humidity of up to 80% (lower temperatures extend and higher temperatures shorten the drying time).
- 48 hours, if during this time the temperature is between +5 °C and +10 °C and the humidity is up to 80%.
- Allows polystyrene foam to be fixed with adhesive only in buildings up to 12 metres high - in cases and façade locations where mechanical fixing is not a necessity due to other factors, e.g. in the corners of buildings or in the event of strong wind loads.
- High durability during use - through the high proportion of redispersible polymers, microfibres and special additives and modifiers, an increase in the adhesive's durability, resistance to weather and thermal effects has been achieved.
- Optimally selected formulation - ensures proper adhesion of the adhesive to polystyrene foam and excellent working parameters. When applied to the substrate, the adhesive does not roll, tear or pull.
- High viscosity - the adhesive does not slip from the trowel or from the surface of the board - this allows to carry out work faster and at the same time reduces the loss of material.
- It has high ad hesion - due to the increased content of polymer dispersions, it shows high adhesion to mineral surfaces and to EPS panels. This parameter is also favourably influenced by the varied, tight bulk stack of the aggregate mixture. The mortar adheres strongly to difficult substrates, e.g. surfaces covered with strongly adhering layers of paint.
