Vapor Score Calcium Chloride Test Kit – Moisture Test for Concrete (Single Unit)

Moisture in concrete can impact flooring adhesion and coating performance. The Vapor Score Calcium Chloride Test Kit provides a quantitative snapshot of moisture vapor emission rate (MVER) based on the widely used ASTM F1869 method. This industry-standard approach helps you gauge slab readiness before installing adhesives, coatings, or finishes without guessing.

Designed for versatility, the kit remains sealed and ready for use anytime. Durable construction and a sealed package mean you can conduct reliable moisture analysis even when outdoor conditions fluctuate. The test yields results in pounds of water evaporating from a 1000 ft2 area over a 24-hour period, offering a practical data point to compare against manufacturer guidelines. Note that readings reflect the slab's current condition under the test temperature and humidity, so plan testing accordingly.

Why consider this kit

Precision matters when preparing a subfloor. The method provides a tangible figure that can support scheduling and product selection for flooring, coatings, or adhesives. While results are not a guarantee, they can guide decisions and help you avoid surprises once a project moves forward.

• Precise, industry-standard testing to support surface preparation decisions.
• Easy-to-use design with clear instructions for DIYers and professionals.
• Helps you anticipate moisture-related risks before installation and reduce rework.

Who is this kit for

Ideal for homeowners, builders, renovators, and property professionals who need a practical moisture check before flooring or coating projects. It fits both new pours and existing slabs, supporting a range of project timelines and budgets.

What’s included and how it works

• Calcium Chloride test pods and distilled water for moisture analysis.
• pH test strips to assess alkalinity that can affect coatings.
• Clear, step-by-step instructions to guide both DIYers and professionals.

To perform the test, place the pod assembly on a prepared concrete surface under controlled temperature and humidity. After 24 hours, weigh the pod to derive a moisture emission reading. The result reflects the current slab condition and should be interpreted alongside manufacturer requirements for your flooring or coating system.

Key benefits at a glance

• ASTM F1869 standard-based approach for dependable accuracy.
• Durable, sealed kit with no expiration date when stored properly.
• Suitable for a variety of professionals and DIY projects, enabling informed planning.

Note: Environmental changes can influence readings. Use these data as part of a broader readiness assessment to plan flooring and coatings with greater confidence.
