ℹ️

Seam Staining Precaution

Oyster White 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.
