ATLAS GRAWIS S 25kg – EPS Insulation Board Adhesive

ATLAS GRAWIS S is a high-performance, fibre-reinforced cement-based adhesive mortar designed for fixing expanded polystyrene (EPS) insulation boards in external wall insulation systems (EWI/ETICS).

Suitable for both white and graphite EPS boards, its carefully formulated composition provides strong adhesion to suitable building substrates and insulation boards. Its high viscosity helps prevent the adhesive from slipping during application, supporting accurate and secure board installation.

Key Features

Fibre-reinforced formulation: Helps improve mechanical performance and resistance to microcracking.
Suitable for white and graphite EPS: Designed for standard and graphite polystyrene insulation boards.
High adhesion: Provides strong bonding to suitable mineral substrates and EPS insulation.
Rapid strength development: Mechanical fixing can generally begin after 24 hours under suitable conditions.
High viscosity: Helps keep adhesive in place during application and board positioning.
Thick insulation compatibility: Suitable for fixing EPS boards up to 500mm thick.
For new builds and renovations: Suitable for external wall insulation on new buildings and existing properties undergoing thermal refurbishment.

Suitable Applications

ATLAS GRAWIS S is intended for:

Fixing EPS insulation boards to suitable exterior walls.
External wall insulation systems using white or graphite EPS.
Thermal upgrades to existing buildings.
Insulation projects involving energy-efficient and passive building construction.

Always follow the current ATLAS technical data sheet and the requirements of the selected insulation system.
