- ATLAS GRAWIS S is produced as a dry mixture of the highest quality cement binder, aggregates and specially selected modifying agents.
- Theoptimally selected formulation - ensures appropriate adhesion of the adhesive to polystyrene foam and excellent working parameters. When applied to the substrate, the adhesive does not roll, tear or pull, and thanks to the extended open time, it allows a larger working area to be covered.
- High adhesion to the substrate and polystyrene foam - due to the increased content of polymer dispersions, it exhibits high adhesion to mineral substrates and to EPS panels (white and graphite), and enables the bonding of thermal insulation panels even with a thickness of 50 cm.
- Fibre strength - the fibres in the product provide additional dispersed reinforcement, so the mortar is protected against micro-cracks and has better mechanical resistance.
- Maximum adhesion after 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 build-up - studding can be started after:
- 24 hours, at a temperature of approx. +20 °C and a humidity level of up to 80% (lower temperatures extend and higher temperatures shorten the drying time),
- 48 hours, if at that time the temperature is between +5 °C and +10 °C and humidity up to 80%.
- High viscosity - the adhesive does not slip off the trowel or the board surface. This allows work to be carried out more quickly while reducing material waste.
