Monument 12x12 Bush Hammered Square Limestone

An easily recognizable material in ancient and modern construction alike, limestone is a strong and beautiful stone that brings natural richness to any surface. Available in three distinct varieties and two finishes, Zia sources limestone for everlasting installations of all kinds.

Limestone is a gift from the earth, formed from natural sedimentary rock. Zia’s limestone collection is quarried and cut outside of Fez, Morocco, where artisans have been cutting and honing this fine building material for centuries.

Each limestone tile is cut from much larger blocks, and then finished by either polishing the surface (honed), or with a high-impact bush hammer machine that uniformly pits the surface of the limestone to create a rough, wonderfully weathered texture.

To ensure proper installation based on unique project and/or site conditions, clients are responsible for hiring a skilled installer that has experience in installing and sealing limestone. Zia Tile is not responsible for installation, ongoing care, or issues arising after receipt and installation of product. If client’s installer deviates from the instructions or recommendations below, this may result in costly and undesirable outcomes.

REVIEWING YOUR ORDER

• Please inspect your order thoroughly, upon receipt. Zia Tile cannot be held responsible for tiles that have already been installed.

• Limestone is a natural stone; therefore, significant variations in color, and subtle variations in shape and size are natural and should be expected in your tiles.

• To account for cuts, pattern, inherent variation, and potential breakage in transit, it is strongly recommended that all orders include a minimum of 15% overage to avoid costly add-on shipping and schedule delays.

BEFORE BEGINNING YOUR INSTALLATION

• As a result of the production process and shipping, your tiles will likely contain a dust residue. Prior to beginning your installation, lay out all tiles and use a heavy spray to remove this residue. Allow all tiles to dry thoroughly before installing.

• Due to the inherent color variation of natural tile, it is very important to blend the tiles from all boxes in your order. You should then lay out all tiles in the installation area and ensure any variation is distributed evenly before beginning your installation.

• There is a face and an underside to limestone tiles, they are not reversible. Prior to installation, ensure you are installing the tile face side up. You may see cut marks or lines from the finishing process which could be present on the underside of the tile.

• Grout color is an important design decision - almost as important as the tile color itself. We recommend exploring Mapei Flexcolor CQ grouts and either selecting a lighter neutral color or matching the grout color as closely as possible to the color of the tile. Visit our website or Instagram to view installation examples to decide what grout color is preferred.

INSTALLATION

REQUIRED MATERIAL

For placing the tiles:

• Sponge

• Bucket

• 1/8” tile spacers

• High quality medium-bed thin set mortar

• Trowel with 1⁄2” semi-circular notches

• Mapei Flexcolor CQ grout

• Grout float

• Grout bag (if using a contrasting color grout)

• Water-cooled tile saw with diamond edge blade

For cleaning and sealing limestone tiles:

• pH neutral cleaner such as Miracle Sealants Heavy Duty Cleaner (Acid Substitute)

• Paint roller, paint tray, sponge and water bucket

• Lint-free cotton cloth

• Penetrating Sealer - 511 Porous Plus Sealer from Miracle Sealants

• For interior applications - Fila Matte Protective Wax

LAYING TILES

• If cuts are required for your installation, all saw cuts must be made with a water-cooled tile saw

FOR FLOOR INSTALLATIONS

• If the subfloor is even and in good condition, a high quality medium-bed thin set is sufficient to set the tiles. Please make sure the subfloor has completely cured (usually a minimum of 30 days) to prevent efflorescence spots from depositing on the surface of the tiles as moisture evaporates through them. Uncured or unsettled sub-surfaces can cause cracks to form in the tile as the sub-surface deforms, so always ensure the sub-surface has cured properly before installing limestone tile. Use of an uncoupling membrane (such as DITRA) may also be advised.

FOR WALL INSTALLATIONS

• Only install limestone tile on stable, even surfaces. In dry areas (i.e. kitchen backsplash), limestone tile may be installed directly to drywall. Never apply tile directly to a painted surface.

• Evenly apply the thin set mixture to the install surface using a trowel. Wet the back of each tile with a sponge before applying the adhesive to the back of each tile, making sure to apply the mixture in the same direction in order to prevent air pockets from forming.

• Lay limestone tile in accordance with the drying time required for the thin set used. Press the tiles into place. Using a rubber mallet, compact the limestone tiles evenly on the adhesive to ensure consistent contact.

• Ensure the tiles are perfectly flat during installation.

• Place in small sections, no larger than 2’x2’, at a time, using 1/8” tile spacers to separate the tiles.

• Immediately wipe off any residual thin set from the surface of the tiles. Thin set can be incredibly difficult to remove without damaging the tiles if left too long.

• After the tiles have been laid, allow the thin set at least 48 hours to cure before sealing and grouting.

PRE-GROUT SEALING

• Limestone tiles must be sealed on-site. Use a pH neutral cleaner before sealing; products made to clean natural stone are usually suitable. Use of acidic cleaners will damage the tiles and should be avoided.

• After your thin set has cured, your tiles have been cleaned and prior to grouting, apply 511 Porous Plus sealer in thin layers until the tiles become fully saturated, wiping off any excess sealer before it dries. Do not over-seal as thick or excessive application of sealant can dry unevenly and result in an undesirable waxy film on the surface of the tiles. Allow sealer to cure, typically 1-2 days; always follow the sealant manufacturer’s application instructions.

• Do not proceed to grouting unless your sealer is fully cured!

GROUTING

• Using MAPEI FLEXCOLOR CQ GROUT, fill in the gaps between the tiles with a rubber grout float. Grout in small areas, no larger than 2’x2’, at a time. DO NOT grout the entire surface at once, as the tiles can stain from excess grout that is extremely difficult to remove later. Instead, grout small areas and immediately wipe away the excess grout as you go. Contrasting grout can stain or leave a grout haze and should be avoided unless hand grouting or using a grout bag.

• Allow the grout to fully cure, usually 48 hours.

TOP COAT SEALER

• Completely clean and dry the tiles with pH neutral detergent, removing any residual mortar or debris. Never leave spills, drips, footprints, or any other marks on the tiles prior to sealing.

FOR INTERIOR INSTALLATIONS

• Apply Fila Matte Finish Protective Wax in thin layers until the tiles are fully coated, wiping off any excess sealer before it dries. Do not over-seal as thick or excessive application of sealant can dry unevenly and result in an undesirable waxy film on the surface of the tiles. Allow sealer to cure, typically 1-2 days before using the space. Always follow the sealant manufacturer’s application instructions.

FOR OUTDOOR INSTALLATIONS

• Apply 511 Porous Plus sealer in thin layers until the tiles are fully coated, wiping off any excess sealer before it dries. Do not over-seal as thick or excessive application of sealant can dry unevenly and result in an undesirable waxy film on the surface of the tiles. Allow sealer to cure, typically 24-48 hours before using the space. Always follow the sealant manufacturer’s application instructions. DO NOT use Fila Matte Finish Protective Wax in outdoor applications as UV rays can cause discoloration over time.

• ALWAYS cover the tiles with durable paperboard during and after installation to prevent damage and/or staining of the tiles until construction is complete.

TRIM

• We recommend installing limestone from floor to ceiling or bringing drywall flush with the finished surface of your tile to eliminate the need for trim.

• If you have an exposed edge with your design, we recommend mitering your tile. Your experienced installer should be familiar with cutting the edges at a 45-degree angle to create a corner out of two tiles. This will mimic a finished trim piece and can easily be done on site to get the finished look without ordering custom trim.

• If you do require trim, we recommend Schluter strips, which can be found at www.schluter.com.

ONGOING MAINTENANCE

Limestone tile is a natural stone product. As such, clients should expect natural wear and patina to occur to the finish over time.

CLEANING

• Vacuum or sweep tile regularly to remove abrasive material that can scratch the surface.

• Promptly clean up any spills, especially oil and grease. Un-cleaned spills can cause stains.

• Floors and walls can be wiped or mopped with warm, clean water and a pH neutral cleaner.

• Limestone tiles should be cleaned using pH neutral cleaners ONLY. Use of acidic cleaners will damage the tiles. For regular cleaning, we recommend Miracle Sealants pH Neutral Tile and Stone Cleaner. For heavier stains, we recommend Miracle Sealants Heavy Duty Cleaner.

RE-SEALING

• Limestone tile should be re-sealed as often as needed, depending on traffic and wear and in accordance with sealant manufacturer’s instructions.
