Description
Cala Gonone is a glass-ceramic mix for walls in bathrooms, showers and other wet rooms. The square chips are 25 × 25 mm, in the colour “turquoise-blue mix”, and the sheets are easy to lay thanks to the silicone backing. The model has the code MOSFBZM055.
Colour and mood
Greenish and blue pieces intertwine like gently rippling water, and the gloss is fresh and lively. It suits showers, spa walls and seaside-style bathrooms best, and brings the feeling of a shallow lagoon on a sunny day.
Why choose this model
- Non-porous glass: water absorption of up to 0.04%, so the surface does not hold on to stains and odours.
- A colour that lasts: neither light (ISO 4892) nor cleaning products (class A under ASTM C650) alter it.
- Strength: it withstands flexural stress of up to 55 N/mm² and has a smooth, defect-free surface.
- Frost resistance: it passes the freeze–thaw test (ASTM C1026).
- Clean composition: made entirely of recycled glass, with no lead, cadmium or other heavy metals in the colourants.
A white grout emphasises the freshness of the mix, while a grey one calms the colours.
Silicone dot backing
In the Cala Gonone sheets, the chips are fixed with small silicone (polyurethane) dots that do not cover their backs. As a result, more than 95% of the back of every chip is exposed to the mortar and adhesion is secure. The backing does not add thickness to the cladding, withstands the chemistry of the adhesive and grout and does not warp in storage. The sheet bends easily and follows rounded surfaces, steps and corners.
| Comparison | Silicone dots | Mesh | Paper |
|---|---|---|---|
| Area exposed to the mortar | over 95% | reduced by the mesh | full, but the paper is on the face |
| Control over the pattern | you see chips and joints | you see chips | the pattern is covered |
| Curved surfaces | easiest – the sheet is flexible | easy | awkward – the paper tears |
| Finishing | no extra work | no extra work | the paper is dampened and peeled off |

How much material you need
Calculate the area of each wall (height times width) and add an allowance for offcuts. For the adhesive, count on about 2 kg per m² for chips up to 25 mm. For the grout, use a calculation of the type (A + B) / (A × B) × C × D × 1.6 kg per m², where A and B are the sides of the chip, C is the thickness and D is the joint width; here these are 25 × 25 mm, 4 mm and 2 mm. The figures are approximate and depend on the substrate, adhesive, grout, trowel and installer – confirm them against the technical data sheets of the materials.
Sold by the carton of 1 m². Take the whole area plus a 5–10% allowance in a single order so that batches do not differ.
Installation step by step
- The substrate must be sound, dry, free of dust and with a deviation from flatness of no more than 2 mm over 2 m. In the shower zone, waterproofing is applied first.
- Fix with a white flexible cementitious mortar of class C2TE S1; a grey one would slightly darken the translucent glass.
- Spread the adhesive with a notched trowel (3–4 mm teeth) over an area sufficient for two or three sheets.
- Lay the sheet and press it down with a rubber float; keep the same 2 mm gap between individual sheets.
- Where a sheet has to be shortened – corners, sockets, pipes – cut the silicone links with a utility knife and cut individual chips with glass mosaic nippers.
- Grout after one day; for the shower, epoxy grout or a waterproof class C2 grout works best.
- Clean off grout residue with a damp sponge before it dries.
- Use the shower only after the grout has fully cured.
Prepare in advance: waterproofing for the shower zone, white adhesive C2TE S1, epoxy or waterproof class C2 grout; a notched trowel with 3–4 mm teeth; a rubber float; a utility knife; glass mosaic nippers; a sponge; a bucket of clean water.
Care and maintenance
- A soft sponge and a neutral cleaner are enough for everyday care.
- Do not use abrasive powders, wire brushes or acids – they damage the grout.
- After showering, go over the surface with a glass squeegee – this leaves no water marks.
Frequently asked questions
What do I fix it with?
White flexible cementitious adhesive of class C2TE S1; white keeps the exact colour of the glass.
Which grout is the right choice?
Wet areas require epoxy or waterproof grout. A white grout emphasises the freshness of the mix, while a grey one calms the colours.
Can I take a smaller quantity?
No – it is sold in whole cartons of 1 m². Choose the whole area you need at once so that it all comes from the same batch.
How does it behave with chlorine and salt water?
This model is meant for walls and wet areas, not for a pool; the glass is not affected by cleaning products.
May it be fixed over old tiling?
Yes, as long as the old tiles are firm, clean, degreased and treated with a suitable primer.
Photo versus reality
Glass is a variable material, and its colour is perceived differently depending on the conditions. There may be a difference between the photos and the mosaic on site because of:
- the monitor or phone – screen settings and brightness;
- the lighting – direct sun, an overcast sky or lamps;
- the viewing angle – glass reflects differently at different angles;
- the shade of the grout and adhesive and the size of the tiled area;
- the surroundings – coping, paving, walls, greenery;
- the batch – with a different production run the tone may differ slightly;
- the natural variety of the chips within a mix.
