Moisture Test Kit: Calcium Chloride (Single Unit) | Vapor Score

Overview

Meet the Vapor Score Moisture Test Kit — Calcium Chloride (Single Unit). This standardized method helps you quantify moisture vapor emission rate (MVER) on concrete subfloors in preparation for flooring, coatings, or adhesive applications. Built around ASTM F1869, the kit provides a practical, numeric figure that aligns with industry expectations while reflecting the current condition of the concrete. The measurement captures the amount of moisture moving into a space over a 24‑hour period across a defined area, empowering you to plan with confidence.

Why choose Vapor Score for moisture testing

• ASTM F1869 accuracy: Reliable moisture vapor testing that supports compliant installations and helps you anticipate common issues before work begins.
• Test with confidence anytime: Durable parts remain reliable over time; the kit seals to resist environmental drift, even in varying temperatures and humidity.
• Protect your investment: Accurate moisture readings can help you avoid costly flooring failures, buckling, or coating delamination by timing installations appropriately.
• DIY, construction & real estate ready: An approachable solution for homeowners, contractors, renovators, and property professionals seeking a clear moisture read.
• Completely easy-to-use: Includes Calcium Chloride test pods, distilled water, and pH test strips, plus step-by-step guidance for both DIYers and pros.

What’s inside and how it works

The kit provides Calcium Chloride test pods, distilled water, and pH test strips to measure moisture vapor and identify potential alkaline conditions that can affect coatings. The test yields a quantitative figure representing moisture vapor emitted over up to 1000 ft2 within a 24-hour window, reflecting the concrete’s current state. For accurate results, perform the test when temperature and humidity are consistent.

What to expect from the results

• Quantitative figure: A numeric moisture read that floor manufacturers often reference when setting thresholds.
• Current-condition indicator: The result reflects present concrete conditions, useful for planning installations.
• Simple interpretation: Compare results against your project’s coating or adhesive requirements to inform scheduling.

Practical use scenarios

• New concrete slabs prepared for flooring, coatings, or adhesives.
• Renovations and environments where precise moisture timing matters.
• Real estate inspections and due diligence to assess substrate readiness.

How to use in a few steps

1. Bring the testing area to a stable temperature and humidity before starting.
2. Set up the Calcium Chloride pods exactly as instructed in the included guide.
3. Seal the test area, then wait 24 hours to capture the emission rate.
4. Read results and compare with manufacturer or project requirements to plan installation timing.

Note: The measurement reflects the current state of the concrete and should be interpreted within the broader context of your project conditions. This kit is designed to support informed decisions, not to guarantee outcomes.
