  1. What is the primary purpose of a surface-applied moisture mitigation system on a concrete slab?

    Answer: To reduce moisture vapor emission to acceptable levels for flooring installation

    Surface-applied moisture mitigation systems are designed to reduce moisture vapor emission rates (MVER) to levels acceptable for flooring adhesive and product warranties.

  2. Which test method measures moisture vapor emission rate (MVER) in pounds per 1,000 sq ft per 24 hours?

    Answer: ASTM F1869 (calcium chloride)

    ASTM F1869 uses the calcium chloride test method to measure moisture vapor emission rate expressed in pounds per 1,000 sq ft per 24 hours.

  3. What relative humidity (RH) reading at 40% slab depth is generally the maximum threshold for installing most resilient flooring?

    Answer: 80% RH

    Most resilient flooring manufacturers specify a maximum of 80% RH at 40% slab depth per ASTM F2170 before installation can proceed.

  4. A two-component epoxy moisture mitigation coating is typically applied in how many coats?

    Answer: Two coats, with the second applied perpendicular to the first

    Two-component epoxy moisture mitigation systems are typically applied in two coats, with the second coat applied perpendicular to the first for uniform coverage.

  5. What surface preparation is most critical before applying a moisture mitigation membrane to concrete?

    Answer: Shot blasting or grinding to achieve an open, porous profile (CSP 2-3)

    Concrete must be mechanically prepared to a CSP 2-3 profile to allow the mitigation coating to properly bond and penetrate the surface.

  6. Which condition would DISQUALIFY a concrete slab from receiving a surface-applied moisture mitigation system?

    Answer: Hydrostatic pressure (water under pressure beneath the slab)

    Hydrostatic pressure (water being forced upward under pressure) cannot be controlled by surface-applied membranes, which are designed for vapor transmission, not standing water pressure.

  7. What does 'pot life' refer to when working with two-component moisture mitigation systems?

    Answer: The time the mixed product remains usable before it hardens

    Pot life is the working time after two components are mixed before the product begins to set and can no longer be applied effectively.
