Saltillo Floor Refinished

 

Here are some photos taken of a recent Saltillo floor we stripped and resealed in Aptos.

Completed with four coats of a high solids floor finish.

Removing the topical finish of this type of floor is VERY time consuming and messy. As the finished starts to break down, red mud develops and can splash the walls. In this case we had a unfinished kitchen to work with so the mess was no big deal. In most situation base boards should be removed so we can scrub right up next to the wall with out fear of damage and the home owner should be prepared to factor in the cost of doing so. Stucco or wood walls the continue all the way to the floor will have to be protected from the splashing.

Another option is to have Connoisseur  just steam clean the floor and apply a coat or two of a topical finish to restore the shine and help hide scratches. Heavy wear and staining will still show to some degree though.

Saltillo tiles are a real conundrum as they are the cheapest tile to purchase but the most difficult to install, clean and maintain.  We have about 300 square feet of Saltillo tiles in our home and love  the look but I warn customers who inquire that a certain mind set has to be in place to not dwell on the floors imperfections but rather embrace their “unique “patina”..

 

 Saltillo tile is a type of terra-cotta tile that originates in Saltillo, Coahuila, Mexico. It is one of the two most famous products of the city, the other being multi-coloured woven sarapes so typical of the region. Saltillo-type tiles are now manufactured at many places in Mexico, and high-fire “Saltillo look” tiles, many from Italy, compete with the terra-cotta originals

Saltillo tile vary in color and shape, but the majority range from in varying hues of reds, oranges and yellows. Tiles are shaped either by pressing quarried clay with a wooden frame (super), or carving out the desired shape (regular). Depending on the raw tile’s placement among other tiles at the time of firing, its color ranges from yellow to a rich orange.

Saltillo tile is highly porous, and soaks in liquid easily. Unlike most ceramic tile, there is no glaze on the top surface of the tile. It is difficult to install as it absorbs water from the thin-set mortar, grout, grease pencils, etc. Once placed, it stains and scuffs easily if not properly sealed and maintained with a quality sealant. Saltillo is probably a poor choice for outdoor installation in freeze-thaw climates, although is a popular choice in warmer climates. During installation the tiles should be handled carefully to avoid stains that can even occur from body oils on the installer’s hands.

Preferred methods for installation invariably relate to its propensity for soaking in liquid. One method involves soaking the tile in water, setting the tile with thin-set mortar, grouting, then sealing both the saltillo and the grout with a quality surface sealant. However, using this method may cause the grout to stick to the surface of the saltillo tile, making it impossible to remove. This method is NOT recommended for do-it-yourselfers.

Another method involves soaking the tile, setting the tile then allowing it to dry, sealing the tile, then grouting. This method prevents the grout from sticking to the tile.

You might ask if it’s possible to seal just the top of the tile before setting…the problem is that soaking the tile allows it to bond more strongly with the mortar, and you probably don’t want to seal the tile, then soak it in water.

A penetrating sealant will maintain the natural look of the tile. You should periodically test the seal by putting a few drops of water on the tile in various places. If the water is absorbed, then another coat of sealant should be applied.

Other surface sealants may give the tile a shiny appearance. As the tile loses its shine, another coat is applied on top of the old sealant. If the finish becomes too worn or uneven, it can be stripped and a new coat applied. However this option is very labor intensive.

Additionally, another coat of sealant can be used on both the saltillo tile and grout. Although inexpensive itself, saltillo is very expensive to have installed. A professional with experience in saltillo will charge $4.50 to $6.00 per square foot for installation and $8.00 to $12.00 a foot to strip and reseal, depending on your locale.

Treatments for saltillo include: coating them with a surface sealant prior to grouting (as mentioned earlier), applying an admixture of linseed oil and paint thinner, applying natural stone color enhancers, applying floor hardeners, applying shine, painting them with a water-based paint, coating them with wood stain, etc. As the tile is incredibly porous it will readily absorb just about any liquid. Please note any of these treatments may be used on the tile, however some of them such as penetrating sealeant, enhancers or linseed oil treatments penetrate into the tile and may affect the ability of later coatings to adhere to the tile. Ultra-durable, water-based polyurethane makes an excellent coating for adding slip resistance, beautiful appearance and protection from penetrating stains. Look for a polyurethane coating that has no VOCs for maximum environmental friendliness.

Saltillo tile may be sealed with a penetrating sealant or a film forming sealant (coating). A film forming sealant will leave a film on the surface of the tile. With multiple coats the film will build an even protective film and gloss that may repel water, oil, grease and efflorescence. A quality acrylic sealant should be used as it will be easy to apply, non-yellowing and long lasting. A quality acrylic floor polish can be applied over the sealed surface for added abrasion and wear protection.

The finished sealed floor should be maintained for best results. For routine cleaning use a neutral cleaner to damp mop the floor (never flood the sealed floor with water). Reapply the polish if areas begin to show wear over time. Maintaining the sealant/polish will greatly extend the life of the sealant and minimize repair needs.
