Concrete Crack Repair Before Epoxy
Cracks left unaddressed are the number-one path to a failed coating. Proper repair is part of prep, not an add-on.
Types of Cracks
Hairline shrinkage, structural, control-joint failure, and settlement.
Repair Method
Route the crack open, vacuum clean, fill with a low-viscosity resin or polymer, and re-grind flush.
Control Joints
Existing control joints are honored or filled with a semi-rigid material depending on the design.
Frequently Asked Questions
Do all cracks need repair?
Working cracks and any crack wider than a hairline must be routed and filled before coating.
Will the crack show through the coating?
Structural cracks may telegraph over time. Cosmetic hairline cracks are typically hidden after repair and flake broadcast.
