Technical Specifications
Dimensional Stability
ASTM C-531 Thermal Coefficient of Linear Expansion tested. 3.3 x 10-5in./in.°F
Do not attempt to install material if the temperature of the Stonres RTZ-2 components and substrate are not within 65 to 85°F/18 to 30°C. The cure time and application properties of the material are severely affected if the temperatures are outside of this range. Stonres RTZ-2 Mortar material is mixed just prior to use in accordance with prescribed directions. The base material is then screed rake applied or by hand with notched trowel. Additional Part C is broadcasted into the surface immediately after raking/troweling. The material is then spike rolled to help embed the chips as well as provide additional air release and leveling. After a minimum of 20 hours curing time, sand the surface of the RTZ Mortar using the recommended grit sandpapers. Squeegee apply and backroll Stonres Groutcoat with a medium nap roller. After 4 hours of minimum cure time, roller apply Stonseal CF7. After 12 hours of cure, inspect and apply Stonres RTZ Skim Coat as per the directions. Apply a second coat of Stonseal CF7. Allow a minimum of 12 hours of cure before foot traffic and 48 hours before washdown/cleaning procedures commence. (Reference the Stonseal CF7 Product Data for further details.) Note: Two coats of Stonseal CF7 are required for all applications of Stonres RTZ-2. Detailed application instructions can be found in the Stonres RTZ-2 Directions.
Suitable Substrates
Suitable for application over properly prepared concrete, wood or steel surfaces. It is not recommended for use over asphalt, mastic, gypsum-based products, brick, or painted surfaces.

Maintenance
For regular maintenance, use Stonkleen DG2 with a mop and bucket or an automatic floor scrubbing machine. Deep cleaning for healthcare environments may require diluted Stonkleen AS9 to remove sanitizing and disinfecting films and residues that are left behind from health code protocols that, over time, will leave heavy build-up and dull the floor.
