Areas of use
Orobico Grey Polished Marble is a stone related to granite (it is also called "marble-granite") because of its special features. Therefore, it can be used in a wide range of interior and exterior decoration projects. Orobico Grey Marble tiles are recommended for heavy pedestrian traffic areas, with dry conditions, as part of residential or public projects. The 1.2 cm thickness also allows for wall cladding with amazing results.
Features
Marble is a non-foliable metamorphic rock, derived from sedimentary rocks subjected to extreme temperatures and pressures, thus modifying their structure and features. Marble is based on calcite, hence the features:
- density: 2 840 kg/m³
- hardness (Mohs scale): 3.5 – 4
- water absorption: 0.6 %
- mechanical strength (compression): 232.71 MPa
- mechanical strength (bending): 11.24 MPa
- fire rating: class A1 (non-flammable)
Marble polishing is essential for its appearance.
Available sizes
Orobico Grey Marble tiles have a standard size of 61 x 30.5 x 1.2 cm. Cappuccino Polished, Tundra Light Polished, or Palisandro Polished marble are also supplied in similar sizes.

How to install marble
Orobico Grey Marble tiles are laid out with the back butter technique. The steps include:
- Surface cleaning: use an industrial vacuum cleaner to remove debris. The surface must be clean, flat, dry, smooth, and load-bearing.
- After measuring the surface, calculate how many tiles will fit on the surface. It is recommended to have a sketch of your project.
- Make a sample (dry assembly): layout a row (full or partial) of tiles on the surface and determine how to cut the edge tiles (those that do not fit). Number the tiles on the back.
- Check out the finish and colors, and decide the layout. If you want a pattern, simply lay put the tiles according to it, simulating a dry assembly. The tiles will be laid out in the desired color layout.
- Make sure installing conditions are observed: dry tiles (protected from humidity for at least 24 hours before installation), installation temperature: 5 - 25 °C (indoor and outdoor), standard humidity.
- Choose and prepare the adhesive according to the manufacturer's instructions. Weberset Marmo Plus, Weberset Porcelain Max², or Weberset Superflex Max² are recommended.
- Start the assembly. Spread the adhesive evenly on the surface with a notched trowel. Depending on the adhesive cure time, it will be applied on smaller surfaces so that it does not cure before laying out the tile. Apply the adhesive to the backing surface and the tile. For cladding wet areas, minimum adhesive coverage of 95% is needed. Large tiles may develop bumps or deformations during installation. These faults can be compensated with the adhesive, deeper grooves should be practiced in the tile surface, using a 10-20 mm notched trowel. The adhesive is applied by the back butter technique, to ensure perfect adhesion. The adhesive is applied in a straight direction; avoid curves formation with the trowel. A line of small parallel grooves is obtained over which the tiles are laid out. For rectangular tiles, apply the adhesive so that the grooves are transversal to the board width. All these operations aim to increase adhesion.
- Start the tiling in one corner to make sure tiles are aligned properly. Layout the tile directly over the surface and press gently, perhaps moving it slightly back and forth without rotating it. The surface should be flat. A rubber mallet can be used.
- The assembly can be completed with or without a joint, in which case expansion joints are provided (depending on the size of the surface). The tiles are installed as a whole, the spaces at the edge of the tiling surface remaining empty. After fitting the tiles, remove excess adhesive with a damp sponge. If you have underfloor heating, the recommended assembly is with joints. For interior tiling, joints of 1-2 mm are the standard.
- Allow the tiled surface to dry for at least 12 hours or according to adhesive instructions, without stepping on it.
- After installing the full tiles, some uncladded areas are left near edges or for bypassing obstacles. In these places, the tiles should be cut to size. Measure the areas on which the tiles are to be fitted and cut out the cut-outs on each tile, taking care to leave the edge gaps. It is recommended to use a tile-cutting machine equipped with suitable discs.
- Cut out the marked tiles, allow them to dry, and then install them with the same procedure.
- Allow the surface to dry naturally (for 24 hours) without stepping on it.
- Tiles with joints need to be grouted.
- After grouting, remove the excess and allow the surface to dry (for 24 hours).
- Wash the surface with clean water.
Maintenance
Quick and easy 3-step treatments are carried out after installation.
1. Cleaning - is carried out with LTP Grimex, LTP Power Stripper, or other professional cleaners. For stain removal always use specific solutions.
2. Waterproofing - protecting surfaces from dust, water, grease, and staining. LTP MPG, LTP External Stone Sealer, LTO Mattstone H2O are recommended.
3. Maintenance - use neutral cleaners LTP Waxwash and LTP Stonewash.
