Everything you need to know about our handcrafted Moroccan terracotta tiles — from material properties and sealing requirements to installation guidance, format differences, climate performance, and how to choose the right tile for your specific outdoor project.
Material & CraftsmanshipMoroccan terracotta tiles are handmade clay tiles produced in Fez, Morocco using natural clay mined from the local hillsides. The production process begins with raw clay that is soaked, filtered, and worked into a malleable state. Tile makers hand-press the clay into wooden molds — no machinery is used at this stage — and the formed tiles are then left to dry in the sun. Once sun-dried, they are kiln-fired in traditional wood-burning ovens at temperatures sufficient to vitrify the clay body and create a durable, dense tile.
The result is an unglazed terracotta tile with a warm reddish-earth tone, a lightly textured surface, and the slight dimensional variation that is inherent to hand production. No two tiles are identical — tone, surface texture, and edge profile vary from piece to piece — and this natural variation is what gives a Moroccan terracotta installation its living, handmade quality. It is not a defect; it is evidence of the production method.
Standard ceramic and porcelain outdoor tiles are industrially produced — machine-pressed, kiln-fired in automated tunnel kilns, and dimensionally controlled to tight tolerances. Every tile in a batch is nearly identical. Moroccan terracotta is the opposite: hand-pressed, fired in traditional kilns where heat distribution is uneven, and finished with natural variation baked in. The aesthetic difference is immediately apparent in an installed floor — terracotta has depth, warmth, and a surface quality that reads as genuinely handmade. Porcelain reads as manufactured, regardless of how accurately it mimics the terracotta look.
Performance differences are also significant. Natural terracotta stays measurably cooler underfoot than porcelain or dense stone in direct sun — critical for pool decks and patios in Arizona, Nevada, Florida, and Texas climates. Porcelain has zero porosity and requires no sealing, but offers no thermal comfort advantage. Terracotta requires proper sealing but rewards the investment with a surface that improves with age rather than simply wearing.
Our Moroccan terracotta collection includes five distinct formats, each suited to different applications:
Yes — unsealed terracotta is porous and will absorb water, pool chemicals, oils, and dirt that cause staining, efflorescence, and surface spalling over time. Sealing is essential before use in any outdoor or wet environment.
The correct sealer is a penetrating impregnating sealer such as Miracle 511 Porous Plus. It soaks into the clay body rather than forming a surface film, which preserves the natural matte appearance of the tile. Apply in two steps: seal the backs and edges of each tile before installation to prevent moisture ingress from behind, then seal the finished top surface after grouting and grout cure. Avoid topcoat sealers that leave a glossy film — these are slippery when wet and peel over time. Re-apply surface sealer annually in high-traffic or heavily exposed areas, or every two to three years in protected covered spaces.
Properly sealed terracotta is low maintenance. For routine cleaning, a mild pH-neutral cleaner or diluted dish soap with a soft brush removes algae, dust, and light soiling. Rinse thoroughly with water after cleaning. For calcium and mineral scale buildup — common in Arizona, Nevada, Utah, and Texas where water hardness is high — apply a diluted mild acid cleaner (such as a 1:10 white vinegar solution or a dedicated tile descaler) to the affected area, allow to dwell for 5–10 minutes, then scrub gently and rinse. Never use abrasive pads, steel wool, or undiluted acid cleaners, which will scratch and etch the tile surface.
Inspect the sealer annually and reapply when water no longer beads on the surface. This is the single most important maintenance task for outdoor terracotta longevity.
Use a polymer-modified thin-set mortar rated for exterior and wet applications. The back-buttering technique is recommended — apply thin-set to both the substrate and the back of each tile — to ensure full coverage and eliminate voids beneath the tile. Because terracotta tiles have natural variation in thickness (a characteristic of hand production), back-buttering also helps create a level finished surface by compensating for this variation.
For grout, use a sanded polymer-modified grout with mold and efflorescence resistance rated for outdoor use. On pool deck applications, a grout with flexibility additives handles minor substrate movement without cracking. Grout joint width should be at least 3/16 inch to accommodate the dimensional variation inherent in handmade tiles — narrower joints will result in irregular-looking gaps where tile size varies. Seal the grout along with the tile surface.
We recommend the following overage percentages based on format and layout complexity:
Because all tiles are custom made to order with an 8-week lead time, ordering sufficient quantity upfront is essential. Reordering to supplement an insufficient quantity adds 8 weeks to your project timeline and risks a color variation between production batches.
This depends on the specific application and the severity of the freeze-thaw climate. Properly sealed terracotta in protected applications — covered loggia floors, indoor-outdoor vestibules, sheltered courtyard spaces — performs well in most climates because the sealer prevents moisture ingress that would otherwise freeze and expand within the clay body.
For fully exposed outdoor applications in hard-freeze climates (Park City, Aspen, Vail, Denver, Taos) where temperatures regularly drop well below 20°F, we recommend caution. Our glazed zellige and bejmat tiles carry certified frost-proof ratings and are the better specification for fully exposed pool decks and terraces in these climates. In the desert Southwest — Scottsdale, Las Vegas, Palm Springs, Santa Fe — and across the Sun Belt — Florida, Texas, the Gulf Coast — terracotta performs without limitation for all outdoor applications.
The thermal behaviour of a surface material depends on two properties: thermal conductivity (how quickly heat moves through the material) and thermal mass (how much heat the material stores per unit of temperature rise). Natural terracotta has a porous clay body with lower thermal conductivity than dense porcelain or natural stone — heat moves through it more slowly, and the clay's porous structure also dissipates heat through evaporative cooling where slight surface moisture is present.
In practical terms, this means that on a 110°F afternoon in Phoenix or Las Vegas, a terracotta pool deck will be noticeably cooler underfoot than the same deck finished in porcelain, granite, or concrete. This is not a marginal difference — it is the primary reason terracotta has been the preferred outdoor floor material in North Africa, Southern Spain, and the Middle East for over a millennium. It is a climate performance specification, not merely an aesthetic preference.
Properly sealed Moroccan terracotta tiles are safe for use in pool environments — on pool decks, around spa surrounds, on pool step risers, and on wet-area surfaces. Chlorine splash, salt-water spray, and pool chemical exposure do not damage sealed terracotta surfaces. The glaze or sealer surface is chemically inert and resistant to the pH range of standard pool water maintenance.
The key is maintaining the seal. An unsealed or poorly sealed terracotta tile exposed to pool chemicals will absorb chlorine and mineral-laden water, which can cause discoloration and surface degradation over time. Annual seal inspection and reapplication as needed is the primary maintenance task that protects terracotta in pool environments for the long term.
All Moroccan terracotta tiles are custom made to order in Fez, Morocco. We do not maintain pre-made stock inventory. Lead time is approximately 8 weeks from confirmed order and deposit. Production begins when the order is confirmed — the clay is prepared, molds are set, tiles are pressed, sun-dried, and kiln-fired as a single production run for your project.
We recommend coordinating with your contractor or pool builder to place the tile order at the earliest possible stage of project planning. Tile orders should be confirmed no later than 10 weeks before your intended installation date to allow for the 8-week lead time plus shipping and delivery buffer. For projects with tight timelines, contact us at (415) 259-4820 to discuss what is feasible.
Yes, and we strongly recommend it. Because terracotta tiles are handmade with natural color variation, the tone, surface texture, and warmth of the clay can differ between our photography and the tile as it will appear in your specific outdoor lighting conditions. A sample evaluated in your actual space — next to your coping material, under your local sun angle, against your stucco or stone finish — is far more informative than any online product image.
Sample sets ship within 5–7 business days. Each sample is custom-made (we produce no stock), so there is a sample fee that is credited toward your full project order of at least 50 sq ft. Request samples through our sample request page or by calling (415) 259-4820.
