Maroon Di Notte Marble Tile 16"x24"x1/2" Cottage finish

Confirm Where This Tile Can Go

Check the Usage section of your product page for wall, floor, exterior, and pool or spa suitability, and confirm with your installer. Cottage-finish marble is often rated for a wide range of applications, including outdoor floors and walls, but confirm this specific product's freeze-thaw performance for your climate before committing to an exterior installation, since this varies by stone type.

Prepare a Flat, Sound Substrate

Tile can be installed over most structurally sound substrates that are clean, flat, dry, and free of wax, dust, grease, and other debris. Repair, patch, and level any damaged or uneven areas. For walls, use cement backer board or a similarly rated substrate in any area exposed to moisture. Waterproofing beneath the tile is recommended for most floor installations, and is essential in showers, pool surrounds, and other wet areas.

Plan the Layout, Including Free-Length Sequencing if Applicable

Mark the center point of opposing walls and snap chalk lines that intersect at the center of the room or wall field, checking that they're perfectly square. Dry-lay a section of tile with spacers along both lines, blending pieces from multiple boxes as you go.

If your tile comes in a free-length format, plan the sequence of lengths before any adhesive goes down. Lay out enough of the field to check that end joints in adjacent rows don't line up, and that shorter and longer pieces are distributed evenly rather than clustering by size. This is much easier to adjust during a dry layout than after tiles are set.

Choose the Right Mortar

A premium white thin-set meeting ANSI A118.4 or A118.15 is a good baseline, and for larger formats, a large-and-heavy-tile mortar gives better support. Back-butter each tile, adding mortar to the tile back as well as the substrate, for full support and a level surface. If you're working with black marble or another moisture-sensitive stone type, confirm the right mortar with your supplier before you start; this is worth double-checking on Cottage-finish collections specifically, since black is a common color option here.

Seal Before Grouting

Apply a penetrating, impregnating sealer to the tile face before grouting. This acts as a grout release, keeping grout pigment and moisture from soaking into the stone during the grouting process. Follow the sealer's instructions for cure time before you move on to grouting, and keep the tile protected from dust and spills in the meantime.

Cut and Handle the Tile

Mark cuts with a pencil or grease pencil. A wet saw with a stone-rated blade gives the cleanest, most controlled cut. Keep in mind that a cut edge will come out straight and smooth, not chiseled, since that texture is worked into the edge before the tile reaches you; plan cuts so they land at walls, corners, or other spots where a straight edge is less noticeable. If a prominent cut edge needs to match the field's chiseled character, ask your fabricator about hand-finishing it to blend in.

Set the Tile

Spread mortar with the flat side of the trowel, then comb it into ridges with the notched side held at roughly a 45-degree angle, using the trowel size recommended for this tile's weight and format. Don't cover your layout lines, and don't spread more mortar than you can tile within about 15 minutes. Set each tile with a slight push or gentle twist, not a slide, and use spacers or tile leveling clips, especially on larger formats, to keep the surface flush. Because the chiseled edges are naturally irregular, a joint on the more generous side often reads better here than a tight one; check your specific product's recommended joint width, or ask your installer based on how much edge variation you see as you lay it out. Leave a perimeter gap of about 1/4" between the tile field and adjoining walls or fixed surfaces. Wipe excess mortar from the tile face as you go. Avoid walking on the installation for at least 24 hours, or as long as your specific mortar recommends.

Grout the Joints

Wait at least 24 hours, or per your mortar's instructions, before grouting. Work in manageable sections and wipe away excess grout as you go rather than grouting a large area all at once, since marble can stain from grout that's allowed to sit too long. Spread grout diagonally across the joints with a rubber float held at a 45-degree angle to pack it fully, then hold the float closer to 90 degrees to scrape excess from the tile face. Let the grout firm up for 15 to 20 minutes, then wipe the surface with a clean, damp sponge, rinsing frequently, until the joints are smooth and even. Never use vinegar or any other acidic cleaner on marble; it will etch the stone. Use a pH-neutral, stone-safe haze remover instead, and test it in an inconspicuous spot first.

Seal Again, Then Care for the Finish Over Time

Once the grout has cured, apply the sealer's final coat or coats across the whole surface, following the manufacturer's instructions. Plan to reseal roughly every six to twelve months, similar to honed marble.

Sealing protects against staining, but not etching, the dull mark left behind when an acid touches marble on contact. A cottage finish's matte surface means etching and light scratches are much less noticeable here than on a polished tile, which is a real practical advantage in busy kitchens, bathrooms, and outdoor spaces. Wipe up spills like wine, coffee, citrus juice, and tomato-based food promptly, and clean with a cleaner made specifically for natural stone. Skip vinegar, bleach, ammonia, and most general-purpose household cleaners, since many are acidic. Regular sweeping or a vacuum without a beater bar, followed by a damp pH-neutral mop, will keep the surface looking its best, and pay a little extra attention to the chiseled edges, where dust and debris can settle more than on a flat, machine-cut edge.
