Installation Guide
Preparation
How do I prepare the surface for installing encaustic cement tiles? 

Before installation, ensure the surface is dry, level, and completely cured. Remove any dust, grease, or other debris. For areas with significant moisture, like bathrooms or kitchens, apply a waterproofing membrane to prevent moisture from penetrating the substrate. Cement tiles are porous, so it’s crucial that the substrate is solid and waterproof.

What adhesive should I use for encaustic cement tiles? 

Use a rapid-setting, flexible adhesive like Kerakoll H40 Advanced to install encaustic cement tiles. This type of adhesive minimizes water absorption and provides strong bonding, even on substrates that are prone to movement, such as wood or plaster​

How do I install encaustic cement tiles?
  • Adhesive Application: Apply adhesive to both the substrate and the back of the tile (back-buttering) using a notched trowel. Work in small areas (0.2-0.5m²) to ensure even coverage. 
  • Tile Placement: Lay tiles carefully by hand, pressing them firmly into the adhesive. Do not use a hammer or mallet as this can cause micro-cracks in the tiles. Ensure that the tiles are level using a spirit level, and use spacers to maintain a narrow grout line (traditionally 1-2mm). 
  • Curing: Let the tiles sit undisturbed for 12-15 hours to allow the adhesive to dry before sealing and grouting​. 
What grout should I use for encaustic cement tiles? Can I use a dark grout?  

For grouting, we recommend using Kerakoll Fugabella Color or a similar resin-cement grout. Avoid dark-coloured grout as it can stain the surface of the cement tiles. Pre-seal the tiles with Fila PRW200 before applying the grout to protect them from stains. Ensure that grout is pressed thoroughly into the joints. 

How do I grout encaustic cement tiles?
  • Grout Application: Apply the grout carefully with a rubber float, ensuring the joints are fully filled. 
  • Cleaning: Clean off excess grout immediately using a damp sponge, working diagonally across the tiles to avoid disturbing the grout in the joints. 
  • Curing: Let the grout cure for at least 24 hours before sealing​ 
Do I need to seal encaustic cement tiles?

Yes, sealing is essential to protect encaustic cement tiles from stains and moisture. After installation, apply a pre-grouting sealant such as Fila PRW200 to protect the tiles during the grouting process. After grouting, use Fila MP90 Eco Extreme to provide long-term protection. In high-traffic areas or wet rooms, we recommend reapplying the sealant every 12-18 months​.

Can encaustic cement tiles be used in wet areas? 

Yes, encaustic cement tiles can be used in wet areas like bathrooms and kitchens, but they must be sealed properly to protect against water absorption. Ensure the substrate is waterproof, and use a waterproof grout like FugaliteColor. Re-seal the tiles regularly to maintain their integrity in moisture-prone environments​

How do I cut encaustic cement tiles? 

Use a diamond cutter or angle grinder to cut encaustic cement tiles. The surface may become wet or dirty during the cutting process, so clean it immediately to prevent staining. After cutting, wipe the tiles with a damp cloth to remove any debris​

Maintenance and Care
How do I clean encaustic cement tiles on a daily basis? 

For regular cleaning, use a pH-neutral cleaner such as Fila Cleaner Pro diluted in water (1:200). Encaustic cement tiles are porous and should be cleaned gently using a soft mop or cloth. Avoid using excessive water, as these tiles can absorb moisture. Promptly wipe up any spills to avoid staining. Ensure the cleaning product is compatible with both the tiles and the grout.

How do I maintain encaustic cement tiles in the long term? 
  • Regular Sealing: Encaustic cement tiles need to be sealed regularly to prevent staining and moisture absorption. After installation, seal the tiles with a penetrating sealer like Fila MP90 Eco Extreme. Reapply the sealer every 12-18 months, or more often in high-traffic or moisture-prone areas. 
  • Deep Cleaning: For stubborn dirt or grime, use Fila PS87 Pro. Dilute the cleaner (1:5) for deep cleaning, followed by a thorough rinse with clean water. Avoid harsh chemical cleaners that can degrade the surface or the sealant. 

 

What should I avoid when cleaning encaustic cement tiles? 

Avoid using: 

  • Acidic Cleaners: Products with acids or harsh chemicals, such as vinegar, bleach, or ammonia, can damage the tile surface and the grout. Acids can etch the surface, leaving permanent marks. 
  • Abrasive Scrubbers: Avoid using abrasive pads or steel wool, which can scratch the tile’s delicate surface. 
How do I handle stains on encaustic cement tiles? 

For different types of stains: 

  • Oil and Grease: Use a degreasing product like Fila SR95 to lift grease stains. Apply it directly to the stain, let it sit, and wipe away with a soft cloth. 
  • Wine, Coffee, or Organic Stains: Use Fila PS87 Pro to gently remove organic stains. Scrub lightly with a non-abrasive sponge, then rinse with water. 
How do I protect encaustic cement tiles from scratches and damage? 
  • Use Rugs and Mats: Place rugs or mats in high-traffic areas to minimize wear and tear on the tile surface. Entryways, kitchens, and hallways benefit from additional protection. 
  • Furniture Pads: Use felt pads under furniture legs to avoid scratching the tiles 
How often should I reseal encaustic cement tiles? 

Encaustic cement tiles should be resealed every 12-18 months, depending on the amount of traffic and exposure to moisture. Sealing protects the tiles from absorbing liquids and prevents staining. Test the sealer by sprinkling water on the surface—if the water absorbs instead of beading up, it’s time to reseal.

Can encaustic cement tiles be used outdoors? How do I maintain them in exterior applications? 

Yes, encaustic cement tiles can be used outdoors, but they require more frequent sealing and care to protect against weather elements. In outdoor applications: 

  • Regular Sealing: Seal the tiles more frequently (every 6-12 months) due to exposure to rain, UV light, and temperature changes. 
  • Winter Maintenance: In cold climates, avoid using salt or de-icing chemicals, as they can damage the tile surface

Troubleshooting
Why is my grout cracking? 

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. 
Why are my tiles cracking? 

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​.
Why do my newly installed tiles appear hazy?

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​.
What causes loose tiles?

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​. 

 

Why is my grout discoloured? 

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. 
Why do my tiles sound hollow when tapped? 

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. 
Why is the tile surface uneven? 

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​.
