Re-grouting and Re-caulking: What We Do
- Remove caulk.
- Using HEPA filter dust extraction equipment, remove grout to sufficient depth to allow new grout to bond securely with tile bisque (unglazed body of tile).
- NOTE: Re-grouting without sufficient removal of old grout will result in a temporary cosmetic improvement that will begin chipping and peeling, usually within a few weeks or months. Columbia Tile & Grout will not employ this practice for any reason.
- Kill visible mildew.
- Install new mildew-resistant grout.
- Buff the tile surface to remove grout haze, soap scum, and mineral deposits.
- Recaulk all plane-change joints (e.g. corner joints) and joints between tile and non-tile materials with mildew-resistant caulk. This includes both sides of door frames and tracks.
- Seal all new grout with sealer that repels water and most stains.
- Treat shower or tub surround with Bac-Shield™ anti-microbial to inhibit mold growth.
