System Overview

The Neogard RTS Under Tile System uses PMMA/PUMA technology to provide a system which can return to service as soon as one hour after installation, and can be installed in temperatures down to 20°F/-7°C. The high elongation properties of the PMMA/PUMA materials do not require reinforcement typical of other similar systems.

The system features our RTS 200 Membrane and our 300 RTS Flexible Body Coat with 7992 sand aggregate. The system provides excellent waterproofing performance and provides the grip necessary for thin-set tile installation.
