Step 1: Prepare a perfectly level concrete surface to install cement tiles. It is not recommend to lay down the cement tiles directly on a fresh concrete or a layer compacted cement/sand. Over time, this incorrect technique will create uneven floor tiles that could easily become loose, crack or break.
Be mind to calculate 20mm below the line of the intended floor height (15mm for 20x20 tiles and 4mm for mortar).
Step 2: The tiles can be installed by using either glue/adhesive or thin mortar layer bed. To have a good adherence of floors:
- Submerge tiles in a water basin before the installation.
- It is necessary to trowel glue or mortar on both surfaces of leveled surface and at back of tiles by using a toothed paint scraper.
Step 5: Fulfill the joints by grouting liquid. Color of this liquid should be white for the most suitable in any case. Other colors can be used on owner preference. Remove all excessive grouting materials before it is dried.
Step 6: Wash the floors with soap and clean water and leave floors dried completely, then apply suitable penetrating sealer from qualified manufacturers to have the most expecting floor finishes. It is strongly suggested to test sealer with one single tile before apply the whole floor.
Step 7: Depending on traffic frequency, repeat this sealing process every 12-24 months.
TIPS
- Encaustic cement tile is handmade product and made from natural materials so the tiles are subject to contain color variations. It is necessary to check tiles randomly before installation to have better distribution of tiles between laying areas to achieve the most uniform floors.
- Take care to align the tiles so that a regular pattern is maintained throughout the floor
- There will be some calcareous spots on tile surfaces as character of cement tiles to be naturally caused by reaction between chemical factors in cement and water. Those spots will be disappeared automatically from 1 to 2 months afterward of using
- Don't leave any space among the squares. Adjust the squares to form the design well
- A good leveling of your ground will facilitate its polishing.
- Ensure that the tiles are perfectly level throughout the installation, because cement tiles can't be reduced or water polished like marble or terrazzo.
