Sealing Grout
Sealing cement-based grout is one of the most effective ways to reduce maintenance time and keep tiled surfaces looking clean for longer. A grout sealer penetrates the porous surface and creates a barrier against moisture, staining, and mould growth.
- When to seal: New grout should be sealed once fully cured (typically 48–72 hours after installation). Existing grout should be deep cleaned first, then sealed once dry.
- How often: Most grout sealers last 1–2 years depending on traffic and cleaning frequency. Reapply when water no longer beads on the grout surface.
- Types of sealer: Penetrating sealers soak into the grout and are invisible. Topical sealers sit on the surface and can alter appearance. Penetrating sealers are preferred for most professional applications.
Important: Sealing grout is not a substitute for cleaning. It reduces staining but does not prevent it entirely. Regular maintenance cleaning is still required.
Ongoing Maintenance
Between deep cleans, tiled surfaces are best maintained with a neutral pH cleaner at the correct dilution. Avoid using strong alkaline or acidic cleaners as a routine maintenance product — they degrade grout and tile finishes over time with repeated use.
In wet areas such as showers and wet rooms, encourage clients to squeegee surfaces after use and ensure adequate ventilation to reduce mould growth between cleans.
Common Grout and Tile Mistakes
| Mistake | Why It Matters |
|---|---|
| Using bleach as a routine cleaner | Bleach whitens grout temporarily but does not remove the underlying soiling. Repeated use degrades cement grout over time. |
| Using acid on natural stone | Causes permanent etching and surface damage that cannot be reversed without professional restoration. |
| Not rinsing after cleaning | Chemical residue left on tiles attracts soiling faster and can cause streaking and discolouration. |
| Scrubbing without dwell time | Reduces the effectiveness of the chemical significantly. Always allow the product to work before agitating. |
| Using the same mop water across the whole area | Spreads soiling back onto clean areas. Change water regularly and rinse with clean water as a final pass. |
| Ignoring damaged or missing grout | Cracked or missing grout allows moisture behind tiles, leading to structural damage. Flag this to the client. |
