Description
Cayo Guillermo hexagonal mosaic, black-blue with sparkles and 3D relief
Cayo Guillermo is a mosaic made of hexagonal chips with a pyramidal relief, in black and blue, with glittering particles woven in. The surface is grainy and sparkles like a night sky studded with stars.
The result is dramatic and luxurious. The sheets are suitable for modern accent walls in bathrooms and spa areas.
Why choose Cayo Guillermo
- The glass is pore-free – with water absorption of up to 0.04 %, it does not grow mould and does not take up stains or odours.
- The colour withstands sunlight (ISO 4892) and cleaning products (class A under ASTM C650).
- The material tolerates freeze–thaw cycles (ASTM C1026), so it is also suitable for outdoor areas.
- Flexural strength is 55 N/mm² (EN ISO 10545-4), and the surface is smooth and free of defects.
- Eco-friendly composition: 100 % recycled glass, with no lead or cadmium pigments and no heavy metals.

The silicone backing in detail
The chips in a Cayo Guillermo sheet are fixed at the back with small silicone (polyurethane) dots that do not cover the back of the chips. As a result, more than 95 % of each chip stays exposed to the adhesive and the bond is firm.
The backing adds no thickness and stays unchanged by the adhesive, the grout and storage time. The flexible sheet easily follows curved walls, steps and corners.

Applications and use
- Accent wall in a bathroom or spa area
- Kitchen backsplash with pronounced relief
- Receptions, bars and decorative niches
Choosing the grout
A black grout preserves the depth of the colour, while a light grey one highlights the shimmer.
When the mosaic is in a shower or another damp place, use a waterproof or epoxy C2 grout – it lets no moisture through and keeps its colour.
Installation steps
- Preparation. The substrate must be dry, sound, dust-free and level (deviation of up to 2 mm per 2 m). In the shower area, waterproofing is applied first.
- Adhesive. A white flexible cement-based adhesive C2TE S1 is suitable. The glass is slightly translucent, and grey adhesive would stain the colour.
- Application. Using a notched trowel (3–4 mm), spread the adhesive over an area for 2–3 sheets.
- Setting. Press the sheet on evenly with a rubber float and keep the same 2 mm between the individual sheets.
- Cutting. At corners and openings, cut the silicone dots with a utility knife and trim individual chips with glass mosaic nippers.
- Grouting. Start after 24 hours. In damp rooms choose an epoxy or waterproof C2 grout.
- Cleaning. Remove excess grout with a wet sponge while it is still soft; epoxy is cleaned off immediately with a special cleaner.
- Use. The shower can be used once the grout has fully hardened.
Required materials and tools
- C2TE S1 adhesive in white
- grout – epoxy or waterproof
- trowel with 3–4 mm teeth
- rubber float
- cutting knife and special glass mosaic nippers
- bucket, sponge and clean water
The amount of adhesive and grout depends on the evenness of the surface, the absorbency of the substrate and the size of the chips, so check it against the technical data sheets of the chosen products and with your tiler. Add a reserve for cutting to the quantity of mosaic.

Caring for the cladding
- Clean with a soft cloth or sponge and a neutral cleaning product.
- Do not use abrasive powders, wire brushes or acidic products on the grout.
- After a shower, wipe the wall with a rubber squeegee so that no water marks are left.
Ordering
- Cayo Guillermo is sold in multiples of a 1 m² carton.
- Take the quantity you need in one go and add a 5–10 % reserve; that way all cartons will come from the same batch and have the same shade.
Questions and answers
What adhesive does Cayo Guillermo need?
A white flexible cement-based adhesive C2TE S1 – it does not change the colour of the slightly translucent glass.
Which grout should I choose?
For wet areas – an epoxy or waterproof grout.
Can it be laid over old tiles?
Yes, as long as the existing cladding is stable, clean and free of grease; treat it beforehand with a suitable primer.
Is it suitable for a pool with salt water or chlorine?
The mosaic is intended for walls and wet areas, and the glass does not react with cleaning products.
Colour in the photo and in person
Glass mosaic is perceived differently depending on the circumstances, so on site the colour may differ from the one in the photos and visualisations. The following have an influence:
- the screen of the phone, tablet or monitor;
- natural and artificial light;
- the viewing angle;
- the colour of the grout and the adhesive, and the size of the tiled area;
- the surrounding colours – flooring, walls, plants;
- the production batch, in which a slight difference in shade is possible;
- natural differences between individual chips.
The visualisations are indicative. If the exact colour matters, contact us before ordering. Send us the dimensions of the room and we will calculate the square metres and cartons you need.
