We’ll review the differences between our two favorite terracotta tiles
Let's compare the differences between our two favorite terracotta tiles. Before we proceed, we’ll review the definition of terracotta tile.
Terracotta loosely translates to baked earth. Terracotta is generally a clay based, fired earthenware or ceramic. Unless specified, terracotta is typically unglazed and porous. Terracotta is often used for tableware, pottery, roofing, building materials and of course tiles.
Cotto and Saltillo are two types of terracotta tiles with their own unique characteristics. However, both types of terracotta tiles are handmade. Handmade tiles exhibit natural variations, which are inherent traits of natural materials they are made of. These variations in color, texture and sheen are not defects but rather a natural part of the product. We highly recommend ordering samples before making a final purchase to confirm and appreciate these natural variations in each tile.
Color Variation
Saltillo is a natural terracotta with color variations, while Cotto comes in three color variation, red, amber, and brown.
Cotto tiles are available in three color options: Sienna, Umber, and Tierra.
Each color option has slight color variations, ranging from darker to lighter shades.
Traditional Saltillo tile has a wide range of colors.
Gloss and Satin sealed terracotta range from dark reds to gold tones. This is because the sealer deepens the natural clay color, creating a darker color variation resulting in warmer tones and hues.
Matte sealed terracotta tiles range from peach to soft yellows due to the natural state of the clay body. This is most similar to unsealed terracotta when it comes to color, but with minimal layers of sealer to protect from water absorbtion.
Terracotta tiles can vary in color within the same tile.
Size Options
Both Cotto and Saltillo tiles are available in various shapes and sizes. From conventional squares to interlocking patterns.
Keep in mind that Saltillo tiles will range much more in size than Cotto tiles.
Often Saltillo tiles will have variations in size up to ¼ inch different from one tile to another. Due to size variation, Saltillo tiles are going to require a larger grout joint than Cotto tiles. Larger grout joints are ideal for achieving design aesthetics like “hacienda” or “old world”.
Cotto tiles have far less size variation and can be installed with tighter grout joints.
Thickness
Saltillo tiles are going to be significantly thicker than Cotto tiles. Saltillo tiles are about ¾ inch thick. Whereas Spanish Cotto tiles are about ½ inch thick.
Keep size variation in mind for smooth installation!
Density
You should also consider density when comparing both tiles.
Saltillo tiles are hand pressed into wooden molds using the weight of the tile maker, making Saltillo tiles less dense.
Saltillo tiles are fired at a lower temperature which makes them more porous.
The differences in density and firing temperatures result in Saltillo tile being more irregular, slightly “pillow topped”, and porous.
Cotto tiles are denser because of the use of machinery and can be fired at a higher temperature.
Cotto is more refined and less porous. Because of the heavier texture and density, Cotto tiles tend to trap more dirt and require more maintenance to keep clean.
Sealing
Some Saltillo tiles will require sealing due to their porous nature. Saltillo tiles are available in a range of sealed finishes from high gloss to matte.
Often Saltillo seal finishes are referred to as glaze. However, sealer is not glaze. Sealer is dried onto the surface while glaze is fired. Unlike glazing, sealers must be maintained and eventually reapplied. Saltillo tiles that are not adequately sealed are highly susceptible to staining. Saltillo tiles should always be sealed. Read more about Saltillo tile sealer options here.
Cotto, a much denser product, however, they require sealing.
Because Cotto tiles are so dense, it may be difficult for a thick sealer to penetrate properly and dry evenly on the face of the tile. As a result, the sealer will eventually start flaking off the surface, so make sure to choose the proper sealer for the best results.
Only penetrating sealers should be used on Cotto. We recommend the usage of a high quality penetrating sealer such as 511 Impregnator or 511 Porous Plus. ALWAYS test a small area before sealing all of your tile to ensure compatibility.
We recommend taking a look at our Clay Care products. These maintenance items have been carefully tested with our products, and they are designed to preserve your tiles' beauty, ensuring their longevity and durability. From sealers to cleaners, purchasing these maintenance items together with your tiles not only simplifies your order but also prepares you to enjoy your tiles for a long time.
Slip Resistance
It's important to consider slippage when using terracotta on the floor.
Saltillo tiles are generally going to be more slippery, since they require a sealer and have a smooth surface.
Cotto tiles have a significantly rougher surface than Saltillo, making them ideal for indoor or outdoor uses. Cotto tiles are not slippery when wet.
Pricing
Cotto tiles are more expensive than Saltillo because they require more time to produce and are fired at a higher temperature. Saltillo tiles start at lower price per square foot than Cotto tiles
