RIO 1000
Premium bonding mortar for thin natural stone & manufactured veneers.
A factory-blended, polymer-modified mortar engineered for superior bond strength, sag resistance, and workability — the upgrade over standard Type S or field-mixed mortars.
Built for the most demanding veneer installations
RIO 1000 is a polymer-modified, factory-blended mortar specifically designed for bonding thin natural stone and manufactured veneers. Advanced technology and high-quality ingredients deliver excellent workability, greater sag and efflorescence resistance, and superior bond strength — making it the right choice for challenging applications like stacked stone.
