Natural stone, when installed correctly, will wear beautifully with minimal maintenance. As a natural material with glorious color range, striation and fossilization, natural stone has inherent variation within each piece and between batches, adding to the overall beauty of the installation.
INSPECTION, STORAGE & USAGE
Upon receipt of your order, please inspect all material carefully. Rock Mill will not be responsible for product issues once tiles have been installed. Please report any issues to Rock Mill within 30 days. Exercise care when handling each piece during inspection and installation, as edges can chip and surface can scratch. Keep paper in between each tile to protect the face of the tile. Keep tiles dry and store boxes in a dry area, away from dampness, to avoid staining/damage.
SUBSTRATE & MEMBRANES
Rock Mill recommends that a licensed tile contractor should ALWAYS be consulted for complete and proper installation guidance. With all natural stone, please expect slight color variation within each order. For the best look, mix pieces/tiles from different boxes or crates throughout the install process. Wipe any residue off of tiles before installation.
The substrate or surface upon which the stone will be installed should be clean, solid, even and without cracks. For vertical surfaces, the wall should be plumb. Installation should not begin until substrate meets these conditions. Depending on location and usage of stone, an uncoupling/anti-fracture or water-proofing membrane can be used. This will help with vapor management and efflorescence reduction. Follow specific manufacturer instructions.
Stone should be installed using a high-quality thin-set product, applied by a licensed tile contractor. Apply thin-set/ mortar to the substrate, with the appropriate trowel. Use proper sized notched trowel to ensure full bedding of the stone and leave no trowel marks. To avoid moisture absorption through the stone and for optimal adhesion, it is essential that each tile be back-buttered and fully-bedded for firm support. Follow installation instructions as outlined by the Tile Council of North America.
SEALING PRIOR TO GROUTING
After tiles are clean and dry, apply a high-quality, penetrating sealer that will help protect natural stone from damage caused by water, salts and oil-based stains. Treated surfaces are easier to clean and maintain longer. Apply sealer according to the manufacturer’s specific instructions.
Grout should not be applied until a minimum of 24 hours curing time at 70°F (21°C) has occurred.
Grout-free: Mosaics that are butt-jointed or have varying heights & thicknesses within the pattern do not need to be grouted and installation can proceed to the sealing step.
After the grout has dried and stone surface has been thoroughly wiped clean, apply a 2nd coat of a high-quality, penetrating sealer. It is important that sealer be applied according to the manufacturer’s specific instructions. Due to the nature of natural stone, it is recommended that the first coat of sealer be applied BEFORE grouting and that the second coat be applied AFTER grout has been allowed to set.
Please inspect ALL material upon receipt. Claims will not be honored after installation. Rock Mill considers the actions of the installer/contractor/3rd party that customer authorizes to pick up the material to be the responsibility of the customer.
Rock Mill will not honor claims made by the customer, due to unauthorized or improper installation by customer’s installer/contractor. Please ensure that a sufficient quantity of stone is initially ordered to complete the job.
Add-on orders purchased later may vary slightly as new batches may come from different parts of the quarry and will not be guaranteed to match the original order.
All items that are stocked are located at the Rock Mill Gardena, California warehouse.
