Planiprep MRS is an advanced, hydraulic-cement-based skimcoating compound designed for use under moisture-controlling membranes and adhesive systems. It is especially formulated for skimcoating and patching interior horizontal concrete surfaces with high moisture content or where environmental controls are not operational. Planiprep MRS has no moisture vapor emission rate (MVER) limitations and can be installed without testing on properly prepared concrete substrates.

• Easy mixing and smooth application characteristics
• Not affected by high moisture conditions
• Can be placed before HVAC systems or interior finishes are installed
• High compression strength for use in heavy traffic conditions
