Care Instructions
Maintenance recommendations for Atlas Grey
🧹 Daily Cleaning
- Wipe surfaces with a soft, damp cloth or microfiber towel
- Use a pH-neutral stone cleaner — never use acidic or abrasive products
- Avoid lemon, vinegar, wine, or any acidic substance on the surface
- Blot spills immediately — do not wipe, as this spreads the acid
💧 Sealing Schedule
- Sealer type: Yes (impregnator)
- Seal every 1–2 years for normal residential use
- Test with water drops — if absorption occurs within 10 minutes, it's time to reseal
- Always clean the surface thoroughly before applying sealer
- Allow sealer to cure fully before using the surface (typically 24 hours)
⚠️ Warning Signs — Time to Call a Pro
- Dull spots or rings where liquids have sat on the surface
- Visible cracks, chips, or separating seams
- Discoloration or staining that won't clean away
- Surface feels rough or gritty in areas that were previously smooth
- White marks or dulled areas from acid etching (lemon, vinegar, wine)
- Grout deterioration around the stone edges
