Product Information

Don't Let Damp Concrete Ruin Your Project-

Penetrate and Seal the Substrate with Just One Coat!

Problem Solver on Damp Concrete

SCHÖNOX EPA RAPID is a two-part, epoxy-based moisture mitigation system. It is designed to be a problem solver for damp concrete (after the concrete is visually dry). It will reduce moisture vapor emission rates from 100% RH (or 25 lbs/1,000 sq ft/24 hours) to suitable levels before applying SCHÖNOX underlayments.

This solvent-free, 100% solids epoxy has a low viscosity, so it penetrates deep into the substrate. It is waterproof, resistant to chemical loadings, can be used on both interior and exterior surfaces.

Easy to Apply, Dries Fast

When properly applied, SCHÖNOX EPA RAPID will penetrate and fully seal the substrate with a single coat. Treated floors are ready for leveling (after back roll) in as little as 2-3 hours (at 65°F floor temperature).

Multiple Applications

SCHÖNOX EPA RAPID may be used as a migration barrier over abated concrete slabs prior to installing SCHÖNOX underlayments. It can also be used as a primer to solidify substrates, such as wood, gypsum-based substrates, or adhesive residues.

Meets and Exceeds Industry Requirements

SCHÖNOX EPA RAPID meets or exceeds the requirements of ASTM F3010-13. It also complies to SCAQMD 1113.

Key Specifications:

  • Coverage Rate: Approximately 300 sq ft per unit (Note: The finished application must cover the substrate completely without any voids or pinholes to ensure moisture vapor suppression)
  • Ready for Leveling (after back roll): After approximately 2-3 hours at 65°F floor temperature
  • LEED: EQc2 Low-Emitting Materials - 1 to 3 points
  • Working Time: Approximately 10 minutes at 65°F
  • Working Temperature: Not below 50°F floor temperature (recommended: > 65°F, relative humidity 74%)
  • Shelf Life: 24 months, unopened
  • Storage Temperature: not below 41°F
  • Color: Transparent Amber
  • Density: 1.1 kg/l (mixed material)
  • Permeance (ASTM): ‰¤ 0.1 perm

*All values are approximate at 65 °F floor temperature, are subject to local climatic fluctuations and vary according to the absorbency of the substrate and to the applicator device. Lower temperatures will lengthen the working and curing time, higher temperatures may shorten it significantly. Do not install underlayment or topping before the substrate has dried thoroughly.
