ℹ️
Seam Staining Precaution
Mountain White Marble can absorb oils from fabrication adhesives, potentially causing darkening along seams and edges. Ask your fabricator to seal all cut edges with an impregnating sealer before applying adhesive, and to use a non-staining epoxy rated for natural stone. This simple precaution prevents most seam-staining issues.

Care Instructions
Maintenance recommendations for Mountain White Marble
🧹 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
