Fill Cracks in the Concrete Floor

What happens here

After confirming the concrete floor's readiness, the next crucial step before epoxy application is to address any existing cracks. Using a dual-barrel caulk gun loaded with a suitable concrete crack filler (often gray in color to blend with concrete), carefully apply the filler into all visible cracks. Hold the caulk gun steady, maintaining a consistent bead of filler along the crack. Ensure the crack is completely filled from bottom to top, creating a smooth, level surface. Some fillers may require tooling or smoothing with a trowel or finger (wearing gloves) after application, though this specific video doesn't show that step. This process helps create a uniform surface for the epoxy, preventing future crack propagation and ensuring a seamless finish.
