Step 1: Prepare the Substrate
Prepare a clean, dry and perfectly level concrete substrate before installation.
Do not install cement tiles directly onto a fresh concrete or an unlevelled compacted cement-sand base, as this may cause tiles to become uneven, loose, cracked or broken over time.
Allow approximately 20mm below the finished floor level:
- 15mm for the 20x20mm cement tile
- 4mm for the adhesive or mortar bed
Tiles can be installed by using tile adhesive or thin-bed mortar. For good adhesion:
- Lightly soak the tiles in clean water before installation.
- Apply adhesive or mortar evenly to both the substrate and the back of the tile using a notched trowel.
Carefully place the tiles to avoid chipping the edges.
After laying, adjust and level the tiles using straightedge and hand pressure. Do not use a rubber mallet as impact may cause cracks.
Maintain a very narrow joint of approximately 1mm between tiles.
Immediately remove any excess adhesive or mortar from the tile surfaces and edges using damp cloth or sponge.
Do not allow adhesive or mortar to dry on the tile surface, as it may become difficult to remove.
Protect the finished floor and allow the adhesive or mortar to cure completely before grouting.
Step 5: Grouting
Fill the joints with suitable cementitious grout.
White grout is generally recommended for the most neutral appearance, white other colors may be selected according to the design.
Remove excess grout from the tile surface before it dries.
Step 6: Cleaning and Sealing
After grouting, clean the floor with mild soap and clean water and allow it to dry completely.
Apply suitable penetrating sealer from qualified manufacturer according to the manufacturer's instructions.
Always test the sealer on one tile or a small inconspicuous area before applying it to the entire floor.
Step 7: Periodic Resealing
Depending on traffic and usage, reseal the floor every 12-24 months or as recommended by the sealer manufacturer.
TIPS
- Encaustic cement tile is handmade product made from natural materials and may have slight variations in color and appearance. Check and mix tiles from different batches or boxes before installation to achieve a more uniform overall appearance.
- Carefully align the tiles to maintain the intended pattern throughout the floor
- Calcareous spots and efflorescense may naturally appear on cement tile surfaces due to the reaction between cement, water and minerals. These may gradually disappeared with normal use.
- Keep the joints narrow and consistent to maintain the intended pattern.
- A properly levelled substrate will facilitate subsequent cleaning and polishing.
- Ensure that all tiles are properly aligned and level during installation. Cement tiles cannot be ground down or water-polished like marble or terrazzo after installation.
