epoxy preparation

No, epoxy cannot hide cracks—it will telegraph through and eventually crack along the same line. Even hairline cracks must be properly filled and sealed before epoxy application. Attempting to coat over unrepaired cracks leads to premature coating failure, typically within 6-18 months, requiring expensive removal and reinstallation.

Epoxy injection repairs need 24-48 hours at typical Porter Ranch temperatures, while polyurethane sealants require 3-7 days depending on humidity. Cold weather can extend these times significantly. Always verify the repair has fully hardened using the scratch test before proceeding with surface preparation and coating.

Cracks wider than 1/2 inch, those showing vertical displacement over 1/4 inch, or cracks that continue growing over time require structural evaluation. Stair-step patterns, parallel cracks spanning the garage length, or cracks accompanied by sticking doors and sloping floors signal foundation issues that must be addressed before any cosmetic coating work.

We recommend structural assessment when crack patterns indicate active foundation movement because coating over unstable foundations wastes your investment. At (818) 355-3804, we prioritize installations that last decades over quick sales that fail within years. Proper diagnosis protects both your home's structural integrity and your epoxy investment.
