Installation and Maintenance
Please note that this is not a complete guide to installation and maintenance but some advice on aspects which we from our experience have found to be particularly important.
Installing the tiles
Step 1 - Setting the tiles
Since the tiles are hand-made and therefore subject to color variation we recommend that you batch mix them randomly from different boxes when laying them out in order to balance color and tonal variation.
Make sure that the surface that is to be tiled is level, clean and perfectly dry.
Before laying the tiles briefly dip them in water to remove any dust and in order to pre-wet the back side prior to setting. Alternatively, you can pre-wet the back of the tile using a spray bottle.
Installation of cement tiles requires a double spread of adhesive. Use thin-set mortar and a notched trowel and apply the thin-set both to the substrate and to the back of the tile.
The pattern of the tiles look best with small grout joints (1-3 mm); in some countries insurance company policies require wider joints e.g. in wet areas - please check before installation. Wider joints are also neccessary when using floor heating cables.
When installing press the tiles down firmly into place only by hand - don't use a hammer or rubber mallet since this can crack the tiles.
Work in small areas at a time and avoid getting the thin-set on to the surface of the tile since this can stain the unsealed tile - wipe off any excess thin-set or other dirt immediately so as to avoid it setting in the porous surface.
Once the tiles are set allow to stand until the surface of the tiles is dry. Wipe off any dirt Before proceeding to Step 3. The tiles need to be clean and dry before sealing.
Step 2 - Sealing. Please note that sealing has to be performed before grouting, otherwise grout can penetrate the porous surface of the tiles.
The tiles then have to be sealed in order to protect them from water and dirt. There are numerous products on the market for this purpose e.g. 511 H2O Plus from Miracle Sealants Company, Stain Stop by Lithofin and Mattstone H2O by LTP.
We have found 511 H2O Plus to be particularly efficient and easy to use - see www.miraclesealants.com (in Sweden www.mpdiy.com). Apply twice, apart fromt that follow the instructions on the container. While protecting against dirt this will maintain the original matte (and "raw") look of the tile. If you want a brighter and somewhat darker finish we instead recommend you to use Miracle 511 Seal and Enhance. (LTP has a similar product).
Be aware that sealing in itself does not prevent excess grout (see step 3 - grouting) from sticking to the surface. It is thus of paramount importance that any excess grout on the face of the tiles is wiped off immediately and meticulously.
Step 3 - Grouting
Before grouting tiles should be allowed to dry for at least 24 hours.
Mix the grout to a slightly runny consistency in order to facilitate applying to small grout joints (1-3 mm). Apply the grout to small areas at a time so that any excess grout on the face of the tiles can be wiped off immediately. Use a Scotch-Brite pad if neccessary.
We advise against using dark colored grout with pale tiles and vice versa.
Step 4 - After treatment
Once the tiles are dry we recommend an after treatment with either concentrated soft soap (uncolored, neutral) or a product like Lithofin Easy Care. Alternatively if you want to enhance the colors we recommend you to use a product like Mira Matte by Miracle (not neccessary if you have already used Miracle 511 Seal and Enhance or similar products under Step 3.)
The tiles should be cleaned using mild soap based detergents (diluted soft soap if available in your market) or a product like Lithofin Easy Carre. Repeated cleaning with soft soap will also help maintain a satin finish to the tiles and to an extent acts as a continuous re-sealant.
Depending on the amount of foot traffic the tiles will have to be re-sealed periodically using a penetrating sealer.
Never use acidic cleaners or other acids on cement tiles.
Tiles can be installed outdoors but there are special considerations. Please consult Marrakech Design prior to purchasing tiles with this aim.
Complaints and claims
Inspect your tiles prior to installation. No returns or claims will be accepted once the tiles have been installed. Please note that Marrakech Design will never assume any responsibility for faulty workmanship.
