True Geology: Sodalite Syenite
Blue Bahia is commercially sold as granite, but is geologically a sodalite syenite. This affects its actual physical and chemical properties.

Slab Yard Diagnostic Protocol
Granite is one of the most reliable countertop stones — durable, heat resistant, and rarely mislabeled. A short verification with your Stone ID Kit confirms the slab matches the spec.

Blue Bahia / Azul Bahia: Test for Calcite Areas
Blue Bahia is a sodalite-rich material sold commercially as granite. Some slabs may contain calcite-bearing areas in the matrix, so acidic spills or cleaners can dull or etch those areas. Test the actual slab before purchase and use pH-neutral care only.
⚡
Factory Resin — Direct Sunlight Caution
Blue Bahia is commonly factory-resined to consolidate fissures and stabilize the slab for sale. Standard resin is often not UV-stable and may discolor or lighten with prolonged direct sunlight. For sunny windows, outdoor kitchens, sunrooms, or exterior use, ask the supplier/fabricator about resin type and UV protection before buying.
ℹ️
True Geology: Sodalite Syenite
Blue Bahia is commercially sold as granite, but it is geologically a sodalite syenite. This distinction matters because true geological classification determines the stone's actual physical and chemical properties — which affects how it performs, how it should be maintained, and how it reacts to acids and moisture.

Care Instructions
Maintenance recommendations for Blue Bahia
🧹 Daily Cleaning
- Wipe surfaces with a soft, damp cloth or microfiber towel
- Use a pH-neutral stone cleaner — never use acidic or abrasive products
💧 Sealing Schedule
- Sealer type: Yes (premium impregnator). Avoid prolonged direct UV/sun exposure unless the fabricator confirms UV-stable resin or protective design measures.
- 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
- Grout deterioration around the stone edges
