Installing an Encaustic tile is a skill. In order to get the best result, the best way to start is by using an amazing installer. Encaustic tiles require a different skillset compared to installing ceramic tiles. If an installer says he will have a go, say NO. As handmade tiles they require a delicacy and ability.

It is essential that the surface of the tile is level, clean, and perfectly dry. Cement tiles are porous in their natural, raw state. They should be treated with a penetrating sealant wherever they are installed. The sealant will protect the tile from staining. Further sealing and finishing is a question of personal taste and installation location

Work in small areas of just 3-4 feet at a time so that the tiles can be cleaned properly as they are installed. Patterns look best with small grout joints (about 1-2 mm), although a grout joint of 2-4mm is recommended for tiles laid over radiant heat. Cement tiles should be installed with thin-set mortar, using a double-adhesive process, whereby the mortar is applied to a clean, level substrate as well as to the back of the tile using a notched trowel or similar.

If setting the tiles on a concrete slab on grade, provide a moisture barrier.

Otherwise, be certain the concrete substrate is fully cured to prevent white efflorescence spots from showing on the tiles after installation.

Submerge the tiles in clean water before they are laid to remove any dust from the back of the tile.

During installation, tiles should be gently pressed into place by hand; never strike the tiles with a hammer (even a rubber hammer) as this will cause cracking. Be sure to clean off any of the mortar from the face of the tiles as you work

Tiles should be allowed to set for 24 hours before applying grout to the joints with a trowel or sponge.A non-pigmented, flexible, cementitious grout like those available from Laticrete is recommended.Carefully clean the surface of the tile as they are grouted to keep the grout from setting in the tiles’ porous surface. (Even with a pre-sealed tile, it is important to clean the tiles during the various phases of the install.)If any cement residue remains on the face of the tile, a Scotch-Brite pad or fine-grained sandpaper can be used to gently remove the residue. Much care should be taken if doing this as it is easy to damage the seal on the tiles and actual surface of the tile. If the tiles are being cleaned properly as you work, you should not have this issue

Try to use grouts with a low level of pigment. Try to avoid bright colors but if that is part of the design please follow the steps below. Our advice is always trying to use the darkest grout possible that you feel comfortable with, without going darker than the tile. Remember you want to see tiles not the grout.

Once the tiles have been grouted and properly cleaned, leave them until completely dry. Apply 1-2 coats of sealant, allowing it to dry a minimum of 3 hours between coats. Once dry, finish with either Fila Satin or Fila Matt. The sealant will oil and waterproof the tile. Please make sure the tile is completely clean otherwise you will be sealing in any stains.Please make sure you contact the manufacturer as they can give you full directions on the best way to apply their products and dilution levels for encaustic tiles.

Well Yes and no. You can for sure but we would not advise it. However, if you really want to add it and it’s the look you are going for, please make sure:

To seal before and after grouting
Completely saturate and remove any excess that does not soak after a few minutes
Make sure to bleed the grout around the edges of the tile before grouting.
When using these grouts the color could leech into the tile causing what could cause a tramline affect.
Be very delicate when grouting- almost point grouting and be sure not to get any on the tiles.
Pre-clean before each sealing stage

Once the tiles have been grouted and properly cleaned leave them to dry completely. Regardless of where the tiles are installed, a sealant is required to protect the tiles from staining. Depending on the type of sealant used, the appearance of the tile can range from matte to a satin finish. Most tile or hardware companies stock Lithofin products. There is an eco-version but we would recommend the non-eco. Apply 2-3 coats of sealant with a sponge, carefully removing any excess from the tile’s surface. Applying the sealant is not about how many times, its more about completely saturating the tiles and removing anything that does not soak in after a few minutes. Keep repeating this until it is no longer penetrating the tiles. Sealant manufacturers’ instructions should be followed by a professional installer.

One of the attributes of cement tiles is that they improve with age and wear and cleaning. The tiles should be regularly washed with mild soap and water.Never use bleach or acidic products to clean the tiles.Depending on the level of luster you desire, additional coats of sealant or wax can be applied as the tiles’ finish become duller. When the sealants are rubbed into the tiles and polished, a lovely lustrous patina can be achieved. The type of sealant or wax, as well as the number of coats, will impact the look of the tiles, which naturally have a matte finish. Depending on the traffic on the floor, the sealant should be re-applied once every 5 years
