Terracotta tile sealing is easily accomplished as terracotta is made from natural clays. This is evident as there are color differences that arise from the firing process. Terracotta tiles do not burn as intensely as other tiles and can be significantly more porous. Therefore, sealing terracotta tiles is crucial to decrease their natural absorption capacity. A good reason to seal terracotta is to protect it from wear and tear. Another is to decrease maintenance and reduce the likelihood of stains. Additionally, sealing the terracotta will give the floor a natural finish that will enhance the color and beauty of the floors.
For terracotta tile floors, it is suggested that you only use cement and clean yellow plaster sand in a 1:1 ratio when grouting the tiles. Grout mix should only be added with jointing liquids where proper and immediate cleanup can be accomplished. If you use prepackaged grout, you must be careful because these materials contain plasticizers, pigments, and latex resins that can cause staining if not properly cleaned immediately after grouting.
When grouting, grout only small areas of the floors at a time because excess grout on the tile surface must be cleaned up immediately before it dries. Grout cleaner can also be added to water to help clean grout easily.
After grouting, you can use an acid-based cleaner to clean away cement residue and grout. After using acid-based cleaners, use another cleaner to neutralize the surface. Neutralizing the surfaces can help prevent the terracotta seal from failing.
Why is a terracotta tile sealer important?
Terracotta, natural stones, clay, and cement tiles are all formed, pressed, or quarried materials. Its natural characteristics cannot be changed; therefore, terracotta must be sealed to protect the material from the following:
1. Terracotta sealing can decrease its porosity, decreasing the chance of permanent staining.
2. A sealant can protect you from chemical attacks from acidic materials such as vinegar, coffee, soda, wine, and sugar.
3. Sealing can make the surface more durable as it can increase its resistance to abrasion.
4. Sealing can also enhance the natural finish of the material.
Here are some things to remember when sealing floors.
1. Allow sufficient time for tile adhesive and grout to dry completely before caulking. Consult its label for the proper drying time.
2. Avoid getting your terracotta floors wet for about 24 hours after sealing.
3. Give your terracotta tile sealer at least 4-8 hours drying time before allowing foot traffic.
