Sealed or unsealed — both work in AZ
Travertine is naturally porous, which is exactly why it stays cool underfoot. Sealing trades a bit of that breathability for stain resistance and color enhancement. In Phoenix, most homeowners go unsealed (cooler) unless they have heavy red-wine-and-monsoon-mud lifestyle.
If you do seal
- Use a penetrating, breathable sealer — never a topical "wet look" film around a pool (it gets slippery).
- Reseal every 2–3 years.
- Apply in spring before monsoon, on a clean dry deck, two thin coats.
- Test a small area first — some sealers darken travertine permanently.
Routine maintenance
Rinse monthly, scrub stains with pH-neutral cleaner, never acid (it etches the stone). Re-sand joints every 3–4 years with polymeric sand. Replace any cracked piece immediately — water under one tile spreads fast.
