When it comes to bathroom design, unglazed tiles are a popular choice due to their durability, slip resistance, and natural look. Knowing the right approach to selecting and installing unglazed tiles is essential to ensuring their longevity and aesthetic appeal. This guide will explore the best ways to use unglazed tiles for walls and floors, providing you with practical advice to make your bathroom both beautiful and functional.
Introduction
Unglazed tiles are made from natural clay or porcelain without a glassy coating, making them durable, slip-resistant, and, most importantly, suitable for areas prone to moisture. These tiles offer a more natural, earthy aesthetic that can complement various design styles, from rustic to modern. Their consistent color through the tile body makes them less likely to show scratches or chipping, enhancing their longevity.
Choosing the Right Unglazed Tiles
Durability and Performance
Unglazed tiles are known for their high durability and excellent performance in wet environments. Here's why:
- Density and Hardness: Unglazed porcelain tiles are extremely dense and resistant to wear and abrasion. They are ideal for high-traffic areas like bathrooms where foot traffic is heavy.
- Slip Resistance: Unglazed tiles often have textured surfaces, which provide better traction in wet areas, reducing the risk of slips and falls.
- Colorfastness: The color in unglazed tiles runs through the entire body, making scratches or chips less noticeable. This color consistency ensures that the tile retains its appearance over time.
Common Unglazed Tiles for Bathrooms
- Unglazed Porcelain: High-quality, high-density tiles suited for heavy-duty use. These tiles are ideal for bathroom floors and walls.
- Quarry Tiles: Typically made from natural clay, these tiles offer a rustic, traditional look. They are durable and suitable for both walls and floors in wet areas.
- Terracotta: Often used in rustic designs, terracotta tiles provide a warm, earthy feel. However, note that they are more porous and require sealing if used in bathrooms.
Best Unglazed Tiles for Bathroom Walls and Floors
- Floors: Unglazed porcelain and quarry tiles are excellent choices for bathroom floors. They provide superior traction and resistance to water, making them ideal for areas prone to moisture.
- Walls: Unglazed porcelain and terracotta tiles are great for walls, adding a touch of sophistication and durability. Ensure they are properly sealed to mitigate any risk of moisture absorption.
Installation Guide
Preparation
Before installation, ensure the substrate is flat, clean, and dry. Use cement backer boards or a suitable mortar bed to achieve a stable, flat surface:
- Substrate Preparation: Ensure the surface is clean, flat, and free of debris. Use a float or laser level to check for unevenness.
- Adhesive Selection: Use a polymer-modified thinset adhesive for porous substrates, and a high-quality thinset for unglazed porcelain tiles. This ensures a strong bond between the tile and substrate.
- Grout Recommendation: Use epoxy or high-performance cement grouts for their resistance to stains and moisture. Grouts like Mapei Ultracolor Plus FA or Flexcolor CQ work well for unglazed tiles.
Proper Installation
- Substrate Installation:
- Ensure the substrate is clean and free of debris.
- Use cement backer boards or a suitable mortar bed to create a stable foundation.
Allow the substrate to dry completely before proceeding.
Tile Installation:
- Use a notched trowel to spread the adhesive evenly.
- Press each tile into the adhesive with a slight twisting motion to ensure it adheres properly.
Use a straight edge or level to check for evenness and adjust as needed.
Grouting:
- Grout in small sections to allow the material to set evenly.
Wipe excess grout from the tile surface with a damp sponge.
Sealing:
- Apply a water-based or oil-based sealant to fully sealed both the tiles and grout joints.
- Follow the manufacturer's instructions for curing time and apply in thin, even layers.
Curing Times
- Tile Adhesive: Allow the adhesive to cure for at least 24 hours before setting the tiles.
- Grout: Ensure the grout cures completely, typically around 48-72 hours, before the final clean-up.
Pro Tips for Installation
- Seal Immediately: Seal the tile surfaces with a 511 Porous Plus Penetrating Sealer prior to grouting.
- Final Cleaning: After grout curing, clean the surface with a pH-neutral cleaner and apply Fila Matte Finish Protective Wax for added protection.
- Regular Maintenance: Schedule regular resealing according to manufacturer's instructions (every 1-3 years).
Maintenance and Cleaning
Caring for Unglazed Tiles
- Initial Sealing: Apply a penetrating sealer to unglazed tiles before grouting. This helps prevent stains and maintains the tiles' natural appearance.
- Daily Cleaning: Sweep or vacuum regularly to remove loose dirt and debris.
- Weekly Cleaning: Use a pH-neutral cleaner and a soft cloth or brush to keep the surface clean and shiny.
Cleaning and Stain Removal
- General Cleaning: Sweep dust away first, then damp-mop with warm water and a neutral cleaner like Miracle Sealants pH Neutral Tile and Stone Cleaner.
- Stain Removal: For stubborn stains, consider using Miracle Sealants Heavy Duty Cleaner (Acid Substitute).
- Avoid Harsh Chemicals: Use mild, pH-neutral cleaners to prevent dulling the surface.
Long-term Care
- Re-applying Sealer: Periodically re-seal unglazed tiles according to the manufacturer's instructions. This helps protect against future stains and moisture damage.
Common Mistakes to Avoid
Overlooking Substrate Preparation
- Ensure the surface is fully cleaned and primed before installation to avoid issues with adhesion and durability.
Neglecting Proper Sealing
- Failing to seal unglazed tiles before installation can lead to staining and discoloration over time.
Incorrect Grouting
- Improperly mixed or applied grout can lead to poor adhesion and a hazy appearance. Grout in clean, small sections to ensure a consistent finish.
