FAQ

Can faces wall ceramics also be laid without joints?

Yes, you can lay faces with a shadow joint or a normal joint. The ceramics make either option possible.

How are the ceramics bonded to the surface in commercial projects?

Simply with silicone or a standard mounting adhesive available on the market.

Can the ceramics also be laid in a shower or wet room?

Some faces glazes can be used in shower applications or wet rooms; some cannot. Here you will find an overview of all the faces glazes which are suitable for wet rooms and their corresponding fitting recommendations.

How should the ceramics be bonded and joined in dry and wet areas?

Here you will find our fitting recommendation for dry applications and wet applications. Just the certainty you need when planning and laying tiles.

You have two options when it comes to joints: a cartridge or a sponge. It’s this simple:

Are the ceramics also suitable for outdoors?

No, the ceramics are not designed to withstand frost. Fluctuations in temperature can lead to cracks, water entrapment and spalling in the glaze, which in turn causes damage to the ceramics.

Can plug sockets or fittings also be integrated into the 3D surfaces of the faces tiles?

Yes, if you wish, we can create recesses on the tile elements for different plug sockets or fittings. Individual measurement specifications or custom developments are also possible. Just get in touch!

Is it possible to have custom glazes based on NCS, Pantone, RAL or Farrow and Ball, or another color palette?

Yes, for a development flat-rate fee of €150.00, we can produce something precisely according to your color specifications. In glossy or matt, it’s up to you.

Are custom shapes or radii possible?

Yes, feel free to make a request. As a manufacturer, we love these kinds of challenges.

Can faces tiles be sawn/cut to size?

Yes, the size of our faces tiles can be adapted using conventional water jet cutters, tile cutters or a Flex angle grinder.

How much do the wall ceramics weigh per m²?

This is variable and depends on the respective faces series. The following overview gives you a good basis for planning:

How should the ceramics be cleaned or cared for?

The most important thing first: thanks to their surface characteristics and glaze, ceramic tiles have outstanding cleaning qualities and are very resistant to stains. The more sculptural or rough the tile, the more dust and dirt can accumulate on its surface. Only use strong cleaning agents in an emergency, and avoid using cleaning agents containing hydrofluoric acid or fluoride. These compounds can damage the ceramic surface, even in low concentrations.

Instead, simply use lukewarm water or biodegradable, environmentally-friendly washing agents or neutral cleaning agents for minor dirt. Less is more!

The first clean (final construction cleaning)

You need to be quick if you want to remove construction dust and dirt containing cement from the joints. This is because hardened cement residue can only be removed with special acidic cleaners which, in turn, are so aggressive that they will attack the cement-based grouting material. It is therefore worthwhile to protect joints in advance by wetting them first, and rinsing the entire surface directly after the grouting work.

Ongoing care

In spite of this, regular cleaning is simple and uncomplicated. Dry dirt can simply be brushed away or, ideally, removed with a vacuum cleaner. Depending on the degree of dirt, wet cleaning can be carried out using environmentally-friendly, general household cleaning agents or slightly acidic or alkaline cleaning agents. Additions such as vinegar-based cleaners or neutral soap are also suitable. On the other hand, you should avoid products which contain cosmetic care agents. Over time, this may cause sticky deposits to form which make the tiles more difficult to clean and affect their appearance.
