Understand the Scratch Test Kit and Its Purpose

What happens here

Before applying any epoxy coating, it's essential to assess the hardness of your concrete floor. A scratch test kit is specifically designed for this purpose. The kit typically contains several 'scratch testers,' which are tools with tips made of different materials, each corresponding to a specific hardness level on a scale (e.g., from 2 to 8). The video shows testers with brass and plastic tips, representing lower hardness values, and proceeds up to higher numbers. The purpose of this test is to determine if your concrete (or existing epoxy layer) is adequately cured and hard enough to properly adhere to new coatings or withstand the intended use. For epoxy floors, the desired hardness range for a successful application is generally between a '5' and '7' on this scale. Understanding this range will guide your preparation process and ensure the longevity of your epoxy floor.
