The substrate must be flat, clean, dry, and free of dust or grease before installing Zellige tiles. For walls, a smooth and rigid surface such as cement backer board or plaster is recommended. In wet areas, such as bathrooms or kitchens, a waterproofing membrane should be applied to protect the substrate from moisture. Zellige tiles are uneven by nature, so a well-prepared surface is crucial for a professional finish.

A high-quality, flexible adhesive like Kerakoll H40 Advanced is recommended for Zellige tile installations. This adhesive allows for adjustments due to the handmade, uneven nature of the tiles and provides strong bonding to both walls and floors. Ensure the adhesive is spread evenly with a notched trowel.

• Adhesive Application: Spread the adhesive on the substrate using a notched trowel. Apply a full bed of adhesive to ensure there are no voids beneath the tiles. Zellige tiles should also be back-buttered (apply adhesive to the back of the tile) to ensure full coverage due to their irregular surface. 
• Tile Placement: Press each tile gently into place, leaving minimal gaps (Zellige tiles are traditionally installed with very thin grout lines or no grout at all). Since the tiles vary in size, shuffle tiles from different boxes to create a natural blend and visually balanced surface. 
• Alignment: Zellige tiles are not uniform, so adjust the tiles by hand to ensure a consistent look. Use a spirit level and spacers (if necessary) to ensure the surface is even, but expect some variation in tile height as part of their rustic charm. 

Zellige tiles are typically installed with very minimal or no grout lines. However, if grout is used, a matching color grout or KerakollFugabellaColor is recommended for its flexibility and water-repellent properties. If grout is desired, make sure it’s applied carefully to avoid filling the irregular edges of the tiles too deeply. Use a narrow grout joint to preserve the authentic look​.

• Grout Application: If grout is used, apply it sparingly with a rubber float, pressing it into the joints without covering too much of the irregular tile surface. Wipe the excess grout from the tile surfaces with a damp sponge. 
• Cleaning: Clean off any grout haze using a clean sponge and water immediately after grouting, wiping diagonally across the tiles.

No, Zellige tiles do not need to be sealed, as they are non-porous and naturally resistant to water and stains. However, proper care should be taken during installation to clean off excess grout and adhesive immediately, as any residue left on the tiles can dry and affect their surface​.

Yes, Zellige tiles are perfectly suitable for use in wet areas such as bathrooms and kitchens due to their non-porous nature and resistance to moisture. However, due to their uneven surface, caution should be taken when installing Zellige tiles on floors in wet areas, as they may not be slip-resistant. It’s better to use them on walls in wet environments​.

Zellige tiles should be cut using a diamond blade wet saw to prevent chipping. Due to the handcrafted nature of the tiles, cutting should be done carefully to maintain the integrity of the tile's finish. Wipe off any residue immediately after cutting to avoid staining​.

Zellige tiles should be cleaned gently using a pH-neutral cleaner, like Fila Cleaner Pro diluted in water (1:200). Use a soft cloth, sponge, or mop to avoid scratching the glaze, and avoid soaking the tiles with excessive water, as the grout lines can absorb moisture. Regular sweeping or dusting is recommended to keep the surface free of dirt and debris.​.

Zellige tiles require minimal maintenance, but regular cleaning and protection of the grout are important: 

• Routine Cleaning: Continue using a neutral pH cleaner for regular maintenance to avoid damaging the glaze. 
• Avoid Abrasive Cleaners: To preserve the tile’s handmade look and feel, avoid using acidic or abrasive cleaners that could damage the surface​. 

Avoid using: 

• Acidic Cleaners: Products containing vinegar, bleach, or ammonia can damage the tile’s glaze and cause discoloration over time. 
• Abrasive Scrubbers: Zellige tiles have a glossy finish that can be scratched easily by steel wool or hard brushes​. 

Zellige tiles are non-porous, but the grout can still be susceptible to staining: 

• Surface Stains: Most surface stains can be wiped away with a mild, neutral cleaner like Fila PS87 Pro. For tougher stains, let the cleaner sit on the tile for a few minutes before wiping it clean. 
• Grout Stains: If the grout becomes stained, use a gentle grout cleaner. Avoid harsh chemicals that could affect the grout colour or integrity​. 

• Regular Sweeping: Sweep or dust the tiles regularly to remove dirt and grit that could scratch the surface. 
• Use Rugs or Mats: Place rugs in high-traffic areas, particularly in entryways, to minimize wear. 
• Furniture Protection: Place felt pads under furniture legs to prevent scratching the tiles. 

Zellige tiles do not require sealing, as they are naturally non-porous and resistant to water. However, the grout should be sealed to protect it from stains and moisture. Grout sealing will help preserve the overall appearance of the installation and make it easier to clean.

Yes, Zellige tiles can be used outdoors as they are frost-resistant and non-porous. However, care should be taken: 

• Regular Cleaning: Maintain outdoor Zellige tiles by cleaning them regularly with a pH-neutral cleaner to remove dirt and debris. 
• Avoid Harsh Conditions: Although Zellige tiles are durable, avoid exposing them to extreme weather conditions for prolonged periods without maintenance 

For a successful tile installation, you will need the following basic tools: 

• Notched Trowel: Used to apply adhesive evenly to the substrate and tile back. 
• Tile Spacers: Essential for ensuring uniform grout lines between tiles. 
• Tile Cutter or Wet Saw: For cutting tiles to size, especially for intricate layouts. 
• Rubber Mallet: Helps gently tap tiles into place without damaging the surface. 
• Level: Ensures that the tiles are installed evenly across the surface. 
• Grout Float: Used to apply grout into the joints between tiles. 
• Sponge: For cleaning off excess grout during and after installation 

The type of adhesive will depend on the tile material and installation environment. Kerakoll H40 Advanced adhesive is highly recommended for various tile types due to its superior flexibility, rapid setting, and structural bonding capabilities: 

• Cement-Based Terrazzo: Use Kerakoll H40 Advanced, a flexible, multipurpose gel adhesive suitable for heavy tiles and large formats. It provides structural support, prevents vertical slip, and works well with substrates like concrete, screeds, and plywood​. 
• Resin-Based Terrazzo: H40 Extreme is ideal for resin-based terrazzo because it accommodates slight substrate movement while ensuring strong adhesion – it also reduces the amount of water in the installation – thereby avoiding moisture-related issues.  
• Porcelain and Ceramic Tiles: Kerakoll H40 Advanced also performs excellently with porcelain and ceramic tiles, offering great flexibility, ensuring full bed adhesion, and preventing tile movement during installation​.

We offer two main types of decorative grouts that are suitable for various applications: 

• Fugabella Color: A resin-cement grout ideal for grouting ceramic tiles, mosaics, and natural stones. It offers: 
• High water repellency and very low water absorption. 
• Superior flexibility and high surface hardness, preventing mold and bacteria growth. 
• Suitable for both internal and external use with excellent color uniformity, available in 50 shades​(Brochure_Color_Fill_psw…)​(H40 Advanced - Data She…). 
• Fugalite Color: A waterproof resin grout that provides stain-proof, chemical, and mechanical resistance. It is ideal for high-traffic and moisture-prone areas such as kitchens and bathrooms. It is also HACCP/EC certified for food hygiene applications and available in 50 colours​. 

Yes, priming or waterproofing the substrate is often required: 

• Waterproofing Membrane: In areas like wet rooms, bathrooms, or external environments, use Kerakoll Aquastop Nanoflex to protect the substrate from water damage. 
• Primer: For absorbent substrates, apply Kerakoll Primer A Eco to improve adhesion and bonding between the tiles and substrate​. 

Grout cracking is usually caused by one of two main issues: 

1. Movement in the Substrate: If the substrate underneath the tiles is not stable or has movement, it can cause stress on the grout, leading to cracks. 
2. Incorrect Grout Mixing: If the grout is mixed with too much water, it can become porous, which weakens the grout and makes it prone to cracking. Ensure proper grout consistency and use a flexible grout in areas that may experience movement. 

Cracking in tiles is often related to substrate movement or improper adhesive application: 

• Movement in the Substrate: If the substrate is unstable or there is movement (e.g., in wooden subfloors), this movement transfers to the tiles, causing them to crack. 
• Improper Adhesive Application: If the wrong adhesive was used or applied unevenly, it can result in voids underneath the tiles, making them susceptible to cracking. Always use a suitable adhesive like Kerakoll H40 Advanced and ensure full adhesive coverage under each tile​. 

A haze on newly installed tiles is usually caused by grout residue left on the surface: 

• Grout Residue: Grout haze is common after installation. To remove it, use a cleaner specifically designed for grout residue removal. 
• Sealed Tiles: If the tiles were sealed before cleaning, the sealer may need to be stripped to properly clean off the grout. Allow the tiles to dry completely before resealing​.

Loose tiles can occur when they are not properly adhered to the substrate. This may be due to: 

• Existing Loose Tiling: If the existing tiles were loose or the substrate was not prepared correctly, new tiles placed over them may not bond properly. It’s essential to ensure that the substrate is solid and free of loose debris​. 
• Improper Adhesive Coverage: Ensure that adhesive is applied evenly across the entire back of the tile (back-buttering) to prevent voids that lead to loose tiles​. 

Grout discoloration is usually caused by improper mixing or cleaning: 

• Incorrect Water-to-Grout Ratio: Adding too much water to grout can weaken its structure, making it prone to discoloration. Always follow the manufacturer’s recommended water-to-grout ratio. 
• Uneven Grout Batches: If different batches of grout are used for the same installation, there may be slight variations in colour. For consistency, mix all the grout needed for a project at once. 

A hollow sound under tiles usually indicates poor bonding with the substrate: 

• Incomplete Adhesive Coverage: If the adhesive wasn’t spread evenly, voids may form under the tiles, causing them to sound hollow. 

An uneven surface is often due to improper levelling of the substrate or inconsistent tile placement: 

• Uneven Substrate: If the substrate is not level, it can lead to tiles being placed unevenly. Always level the substrate using a levelling compound before starting the installation​. 
• Improper Tile Spacing: If spacers are not used or tiles are not aligned carefully, the surface may be uneven. Adjust tiles carefully during installation and check frequently with a level​.
