Joint Filling & Sealing in Gilbert.
Joint Filling & Sealing is the pre-polish or pre-coating work that determines whether the final surface lasts. Control-joint fill with semi-rigid polyurea that flexes with the slab and grinds flush under the final polish. The unsung component of every long-life polished concrete floor.
Most polished concrete failures are prep failures. Skipped grinding, missed joint repair, untreated cracks, insufficient densification , every one of these shows up six months later as a worn surface, a delamination, or a polish that didn’t hold. Mint runs joint filling as a standalone service for GCs and facility managers who want the prep done right before another contractor handles the finish , or as part of a full polished concrete or coating install.

Questions, answered.
Do you do joint filling as a standalone service?
Yes. Mint runs joint filling as standalone scope for GCs and facility managers who want the prep handled correctly before another contractor finishes the floor. All work is ROC-licensed and Danny Carpenter-led. Schedule via the free walkthrough form.
What standards do you work to on joint filling?
ICRI CSP standards for surface profiling, coating manufacturer’s spec for any pre-coating prep, polished concrete protocol for any pre-polish prep. Documentation goes to the project team on request and a copy of the AZ ROC-348746 license is available for any contract.
Is dust control included?
Yes. Every Mint joint filling job runs under HEPA-filtered vacuum systems suitable for occupied buildings. Diamond grinding produces dust, not solvent fumes, so ventilation requirements are straightforward.
