Concrete Moisture Test Kit: Emission Test, 12-Pack

Concrete Moisture Test Kit – Emission Test (12-Pack)

The Concrete Moisture Test Kit (12-Pack) is a reliable solution for measuring moisture vapor emission rate (MVER) in concrete slabs before flooring installation. Moisture movement through concrete is a leading cause of floor covering failures. Unlike electronic meters that only show saturation levels, this kit uses the industry-standard calcium chloride method to measure the actual rate of moisture emission from the slab surface.

Accurate MVER testing helps contractors, inspectors, and builders determine whether a concrete slab is ready for coatings, adhesives, epoxy, or floor coverings. Conducting the test early prevents costly failures caused by excess moisture.

How the Calcium Chloride Test Works

The calcium chloride test is widely accepted in flooring and construction for moisture emission measurement. A pre-weighed container of moisture-absorbing calcium chloride is placed on the concrete surface and sealed under a plastic dome with a butyl rubber gasket. For reliable results, testing should take place when the building’s temperature and humidity reflect normal use conditions.

After 60 to 72 hours, the dome is removed and the calcium chloride dish is sealed and re-weighed. The increase in weight, along with exposure time and test area, is used to calculate moisture emission. Results are expressed as pounds of moisture per 1,000 square feet in 24 hours, providing a clear picture of the slab’s condition.

Recommended Testing Guidelines

To meet manufacturer and industry requirements:

• Conduct three tests for the first 500 sq ft

• Add one test for every additional 500 sq ft

• Test each area separately prior to flooring or coating installation

Following these guidelines ensures accurate results and flooring performance.

What’s Included in the Kit

Each 12-pack kit contains:

• Sealed calcium chloride dishes

• Plastic test domes with pre-installed butyl rubber gaskets

• Three pH test strips with color chart

Including pH testing helps identify alkalinity levels, which can affect adhesive performance and flooring durability.

Benefits

• Accurate moisture emission measurement using an industry-approved method

• Helps prevent flooring failures caused by excess moisture

• Easy to use on site or in lab environments

• Supports compliance with flooring manufacturer guidelines

• Trusted method recommended by industry organizations

Leading authorities in flooring testing emphasize the importance of moisture and pH testing before installation. Using this test kit helps ensure coatings, epoxies, and floor coverings adhere properly and perform well over time.

Summary

The Concrete Moisture Test Kit (12-Pack) provides contractors and flooring professionals with dependable moisture emission testing. Its industry-standard calcium chloride method delivers accurate results that support informed installation decisions and help protect against moisture-related flooring issues.
