Thin-sets specifically formulated or recommended for stone must be used. White mortar is commonly recommended.
Stone products should be adhered to the substrate by use of a white premium latex modified thin-set mortar. If the stone is mesh-reinforced or water sensitive, a white epoxy adhesive must be used.
Non-sanded grout is highly recommended for polished marble, limestone, travertine, and onyx to prevent scratching.
To protect your natural stone from staining, and discoloration, all natural stone must be sealed before and after grouting. If you do not seal prior to grouting, a grout release must be applied to protect the stone from grout residue. Do not utilize the stone application area until it has been properly sealed. Natural stone should be resealed annually or biannually depending on the type of stone and usage level.
Please see the latest edition of the TCNA Handbook for further instruction.
Since stone expands and contracts, a 100% silicon caulking is recommended in all corners where the stone meets the floor or wherever there is a change of plane.
