Product description

Recommended for substrate preparation for bonding ceramic and stone cladding, for underlays of the ATLAS SMS and ATLAS SAM screeds applied on critical substrates.

Properties

ATLAS ULTRAGRUNT is a ready-to-use mass produced on the basis of polymer resins with the addition of selected quartz aggregate.
It has excellent adhesion to non-absorbent substrates and to substrates with a very smooth surface – for concrete substrates the adhesion is a minimum of 1.0 MPa.
The addition of selected quartz aggregate increases the adhesion of the applied layers – by developing an effective surface between the substrate and the material to be laid. Creates a rough surface for the application of the next layer.
Designed for application at elevated temperatures – recommended for use between 5 °C and 35 °C, indoors and outdoors.
It is a fast-drying primer – laying another layer after just 4 hours.
