This is dependent on the specific tile used as not all tiles are suitable for garage floor installation. Since every application and installation is different, we strongly recommend consulting an installer who has experience with this type of installation, who is properly licensed and insured, and will provide a suitable warranty to cover your application. Your installer should verify the conditions and application meet local requirements or industry expectations. Any installation guidelines are not intended to supersede federal, state, or local regulations which may require modifying the existing installation, materials, or structural components. The customer assumes responsibility for compliance with all building codes.
