ROMEX 2-component resin products, including D1, D2000, DRAIN, W1000 and D4000 HR are designed to be used in combination with ROMEX FILLER SAND. The resin binder alone does not create a finished jointing mortar, so the proper filler sand must be mixed with the 2-component system to achieve the required consistency, joint stability, and long-term performance.

ROMEX FILLER SAND is sold separately and should be ordered along with the appropriate 2-component product to ensure the system is installed correctly.
