Confirm Where This Tile Can Go

Not all ceramic tile performs the same way in every location, and this is one of the biggest differences between ceramic and natural stone or porcelain. Glazed ceramic tile is rated on the PEI scale (0–5), which measures how well the glaze resists surface abrasion. A rating of 0–1 generally means the tile is intended for walls and light-duty vertical surfaces only; 2 suits light residential foot traffic; 3 and above can handle normal to heavy residential and light commercial floor traffic.

Water absorption matters too. Ceramic tile is typically non-vitreous to semi-vitreous, meaning it absorbs more moisture than porcelain, so use in wet areas (shower floors, exterior applications) depends on the specific product's rating and on proper waterproofing behind it. Check the Usage section of your product page, and when in doubt, confirm suitability with your installer before tiling a floor or wet area.

Prepare the 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 — ceramic tile will telegraph imperfections in the surface underneath it. For walls, use cement backer board or a similarly rated tile substrate in any area exposed to moisture, such as showers or backsplashes near a sink; standard drywall is appropriate only in dry wall areas. For wet installations, install a waterproofing or vapor-management membrane behind the tile, following the membrane manufacturer's instructions. Remove moldings, trim, and appliances that would interfere with installation, and undercut door jambs so tile can slide beneath them.

Plan the Layout

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 row of loose tile with spacers along both lines to see how the cuts fall at the edges; if you'll end up with slivers narrower than half a tile, shift the layout by half a tile width to balance the field.

This step matters even more with decorative and hand-painted ceramic tile. If your tile has a directional pattern, a border motif, or corner details meant to align across the field as with many hand-painted Portuguese and Delft-style tiles dry-lay a larger section first to make sure the pattern reads correctly before any adhesive goes down, and plan your cuts so they fall at edges and corners rather than through a focal motif.

Choose and Mix the Right Mortar

Ceramic tile bonds best with a polymer-modified thin-set mortar (look for one meeting ANSI A118.4 or A118.15 performance standards); these offer better flexibility and bond strength than an unmodified, dry-set mortar. Save unmodified thin-set for situations where a waterproofing or crack-isolation membrane manufacturer specifically calls for it. Choose a white thin-set under light-bodied or light-grouted tile to avoid any gray show-through, and a rapid-setting formula if you're working in a shower or need a faster turnaround before grouting. Mix only what you can use in about 30 minutes, following the manufacturer's water ratio exactly adn too much water weakens the bond.

Cut the Tile

Mark cuts with a pencil or fine felt-tip marker. A snap or score-and-snap cutter works well for straight cuts on most glazed ceramic; a wet saw with a tile-rated blade gives cleaner results for precise or curved cuts, and tile nippers can chip away small notches around outlets or fixtures. Cut with the glazed face up to reduce chipping along the cut edge, and ease sharp edges with a rubbing stone if needed. With hand-painted tile, lay out your cuts before cutting so any trimmed pieces land at the edges of the field rather than through the center of a painted motif.

Set the Tile

Using the trowel size recommended on your mortar's packaging, 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. Don't cover your layout lines, and don't spread more mortar than you can tile within about 15 minutes. Back-butter larger-format tile adding a thin layer of mortar to the tile back as well to improve coverage and reduce hollow spots.

Set each tile with a slight push or gentle twist, not a slide, and insert spacers to keep joints even. Leave a perimeter gap of about 1/4" between the tile field and adjoining walls or fixed surfaces to allow for natural movement. Once a section is set, tap tiles gently with a rubber mallet to bed them evenly, then check the surface for lippage while the mortar is still workable. Wipe excess mortar from tile faces and joints with a damp sponge, and avoid walking on floor installations for at least 24 hours.

Grout the Joints

Wait at least 24 hours (or per your mortar's instructions) before grouting. Use sanded grout for joints of about 1/8" or wider, and unsanded grout for narrower joints or on tile with a glaze that scratches easily check with your grout manufacturer if you're unsure which type suits your tile's finish. Mix only what you'll use within about 30 minutes.

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 15–20 minutes, then wipe the surface with a clean, damp sponge, rinsing frequently, until the joints are smooth and even. Once a light haze forms, buff it away with a soft, dry cloth. Avoid acidic or abrasive cleaners on glazed and hand-painted tile when removing grout haze they can dull the glaze or wear at painted detail. Stick to water and a soft cloth or sponge.

Cure, Seal, and Care for the Grout

Glazed ceramic tile itself doesn't need to be sealed the glaze is already the protective, water-resistant layer. What does typically need attention is the grout: most cementitious grout benefits from a penetrating grout sealer once fully cured, generally around 2–3 weeks after installation, to help resist staining. Hold off on heavy foot traffic for about 72 hours after grouting, and don't apply any sealer before the grout has fully cured.

For larger installations, include movement (expansion) joints at the perimeter, at changes of plane, and at regular intervals across large fields, per standard tile industry movement joint guidelines your installer can advise on spacing for your specific project.

Once everything is cured, clean glazed and hand-painted ceramic tile with a pH-neutral cleaner and a soft cloth or mop. Skip vinegar, bleach, and abrasive scouring pads, which can dull the glaze and fade hand-painted decoration over time.
