The ARDEX MC™ RAPID Moisture Control System is a one-coat, 100% solids epoxy moisture management system formulated to suppress excessive moisture vapor emissions in new or existing concrete prior to installing an ARDEX underlayment with flooring or an ARDEX topping with sealer.

Key Features

• One-coat epoxy resin system
• For RH readings up to 100%
• Excellent coverage
• Fast setting – Proceed in as little as 4 hours
• No sand broadcast required for underlayment applications of 1/4” (6 mm) or less
• Reduces moisture vapor emissions to acceptable levels for floor coverings
• Solvent free, alkali resistant
• ASTM E96 – 0.06 perms
• Tenacious bond to substrate
• Use under all standard commercial and residential floor coverings on interior substrates only
• Use under all ARDEX interior toppings (sand broadcast method only)

Installation

Mixing Ratio: Add entire pre-measured contents of Part B (Hardener) into Part A (Resin).
