Calcium Chloride Testing: Is Your Floor Ready?

Calcium chloride testing is a vital step in assessing a concrete slab's readiness for covering materials. The test measures a slab's moisture vapor emission rates by placing a pre-weighed calcium chloride disc under a sealed sheet for 24 hours. The accumulated weight helps calculate vapor emission rates, which ideally range between 3-5. Technicians must adhere to specific protocols to ensure accurate results, which include meticulous surface preparation and maintaining the test setup for 60-72 hours.

How to Test Epoxy Bond Strength on Floors

Epoxy bond strength on floors are assessed using specific tools and protocols to ensure adherence to industry standards. Measurement tools include tensile testing machines, peel strength test devices, and surface preparation tools. To determine if a surface is ready for epoxy bonding, technicians conduct various tests such as moisture testing, visual and tactile inspections, pH testing and surface roughness measurements. Pull-off testing, following ASTM D4541 guidelines, measures the epoxy's bond strength by applying a controlled force on the surface.
