A flawless epoxy floor starts with flawless preparation—and that includes repairing every crack in the concrete. Whether you’re installing epoxy in a garage, warehouse, basement, or commercial space, cracks must be opened, cleaned, and filled before coating. This is where concrete crack chasers and router bits become essential tools.
Used by flooring contractors worldwide, these tools help ensure proper adhesion, prevent future cracking through the coating, and create long‑lasting epoxy floors. Below is a breakdown of the best crack chasers and router bits for epoxy floor prep in 2026.
Why Crack Chasers Matter for Epoxy Installation
Concrete naturally expands, contracts, and shifts, causing small or deep cracks. If you apply epoxy without addressing these:
Cracks will telegraph through the coating
Moisture can penetrate and weaken adhesion
Epoxy may split or peel
Repairs become costly
Crack chasers widen and clean cracks into a “V‑groove,” making them easier to fill with epoxy crack filler or polyurea joint repair material.
