General product information
-
Coarse-grained terrazzo tiles are the robust flooring classic of the 20s / 30s.
This characteristic floor still enlivens many hallways and entrances, bathrooms and kitchens today. The coarse-grained Carrara marble aggregate with its natural inclusions and elegant white tone makes all colours, including darker shades, appear light and warm.
The terrazzo floor - a floor that makes an impact!
- Terrazzo has been known as a floor covering since ancient times. This robust material can still be admired today in numerous Venetian palazzos from the Renaissance period. In the past, terrazzo was painstakingly cast on site as an entire surface. Terrazzo tiles now allow for more flexible use.
White, red, grey and black are the four typical terrazzo colours that we offer as plain tiles or mosaic tiles.

Surface
Like cement floor tiles, terrazzo tiles have an open-pored surface. They must be impregnated after installation (see below). Use and maintenance care with moisturising soft soap will create a protective patina over time, bringing the floor to life. Caution is advised with acidic products (red wine, vinegar, etc.). These should be removed immediately if necessary. Manufacture
Terrazzo tiles are traditionally made from a mixture of coloured cement mosaic tiles and coloured aggregates, without synthetic resins or other plastics. The mixture is filled into appropriate templates, pressed at high pressure and then dried. The tiles are then sanded to give them their typical surface appearance.Suitability
Terrazzo tiles are hard-wearing and wear-resistant (similar to marble). Thanks to their slip resistance (R9), they are also suitable for wet rooms such as corridors, entrance areas and bathrooms. If the water is very calcareous, it is not advisable to lay them in shower areas, as they should not be cleaned with acidic cleaning agents.Terrazzo tiles are also suitable for underfloor heating if the floor is heated evenly and at a normal water temperature (22-28°C). Excessive temperature fluctuations should be avoided.
The tiles are only partially frost-resistant and are not suitable for outdoor use.
Specific product features
The characteristic grain of the terrazzo tiles means that the individual tile patterns are not absolutely precise. This slight irregularity gives the floor its own charm. The tiles are sanded with a 120 grit. This process can sometimes cause individual small grains to be torn out at the edges of the slabs, resulting in slight rock breakouts or uneven edges.

Maintenance
Every cleaning process consists of cleaning and maintenance. It is important that the cleaning effect is not achieved with acidic cleaning agents, but with alkaline, slightly moisturising cleaners !!! Acidic cleaning agents roughen the surface and should not be used under any circumstances. Coarse soiling can also be removed with scouring powder (e.g. ATA) and a brush. Traditionally, cement mosaic tiles and terrazzo floors were cleaned with a moisturising soft soap - soft soap contributes to floor care through natural moisturising.Good things take time - a patina only builds up over time and protects the floors maintained in this way.
. Laying
The installation work must be carried out by an installer who is familiar with the specific material properties. We accept no liability for improper installation.- Install on a clean, level and absolutely dry surface. A damp substrate can cause stains on the tile surface.
- Mix tiles from several tile packs together
- Use a fast-setting adhesive with crystalline water binding (e.g. VIA tile adhesive and VIA primer, ARRDEX S20, ARDEX S28 or MAPEI MAPESTONE 1). Moisture penetration should be minimised to avoid capping and cracking. ATTENTION: Do not overwater the rapid adhesive!
- Apply cementitious adhesive with a 10-tooth notch, also apply adhesive to the underside of the slab (buttering-floating method). Work on as small an area as possible.
- Align carefully by hand to avoid overlaps - lay with the narrowest possible joint of max. 1 to 2 mm
The panels are best cut with a diamond blade. Even mitres can be designed so precisely that clean joints on outer edges are possible. Cutting should be carried out dry.
If the laid floor still needs to be covered, this should be done with a breathable material.
Grouting
The tiles are grouted with a slurry consisting of two parts trass cement and one part quartz sand (finest grain size up to 0.3 mm), which are mixed to a yoghurt-like consistency with the addition of water. Do not use ready-made grouts that contain plastic, as these can form a grey haze! Do not use grouting aids, as these prevent subsequent impregnation! Only grout in white, cream or light grey shades should be used. Do not use coloured grouts! The grout is pressed into the joints with a grouting board or spatula and worked in until the joints no longer fall. The grout should not be wiped over the entire floor. Once a section that is easily accessible has been completed, this area should be completely cleaned. Please do not use acids or "cement residue remover" to remove stains!Silicone grouting should be applied before the impregnation is applied. Use a natural stone silicone without vinegar crosslinker to avoid discolouration.
Impregnation
Terrazzo behaves like natural stone or other open-pored materials: If dirt is absorbed into the tiles, it can be assumed that the impregnation is insufficient.Optimal impregnation is only possible if the floor is clean and completely dry and the oil penetrates deeply through the capillary effect. A meaningful test area must be created before complete impregnation. If the oil does not absorb, only a wafer-thin layer will form on the surface through which liquids can diffuse.
Impregnation is carried out with VIA panel oil. Suitable tools are a paint roller (foam) and a commercially available vibrating polishing machine. Soak the foam roller with panel oil to achieve an evenly saturated application of the oil. If the oil is initially absorbed by the surface, re-oil until a thin excess remains. Immediately polish the excess oil into the surface using a polishing machine. Work in easily accessible sections of approx. 3 tile rows towards the exit. The floor can be walked on after one day. After 7 days, the oil is fully cured and the floor is ready for use. The floor must not be cleaned during the curing time.
After the impregnation process, the floor must not absorb any more liquid. This can be checked with a few drops of water. This is the only way to ensure that no dirt is deposited on the surface and that it is easy to clean.
Note: The floor should not be cleaned with grease-dissolving cleaning agents or microfibre cloths for a lengthy period of time. Otherwise, the protective oil will be removed from the floor and dirt can penetrate again.
Basic cleaning
After installation, thorough cleaning is the basis for impregnation. After sweeping or vacuuming the floor, possibly also removing mortar and paint residues, the surface should be wiped with a slightly damp cloth. Coarse building soiling can be scrubbed off with scouring powder after light pre-wetting. Acidification is not permitted! Then wipe the boards sparingly with clean water and allow to dry thoroughly.Maintenance cleaning and care
Every cleaning process consists of cleaning and care. It is important that the cleaning effect is not achieved with acidic cleaning agents, but with alkaline, slightly moisturising agents !!! Acidic cleaning agents roughen the surface and should not be used under any circumstances. Traditionally, cement tile floors were cleaned with soft soap - soft soap contributes to floor care through natural re-greasing. Coarser soiling can be removed with a "Glitzi" sponge and ATA (cleaning agent) or with a so-called "cleaning stone".Good things take time - a patina only builds up over time and protects the floors maintained in this way.
Reconditioning
The boards are given an additional shine by polishing them with diamond polishing pads. Different grit polishing pads are applied one after the other.Source of supply Additional products
