Edera Mosaic – Embossed White and Dark Green Chips 25×25 mm

Description

What is Edera mosaic

Edera is a glass-ceramic tile covering made of embossed 25 × 25 mm squares in white, with dark green chips showing through and an embossed surface. The squares are assembled into sheets that are easy to lay.

The light background with a few dark accents gives a calm yet lively look. The dark green squares stand out clearly, and under water in the sun they glitter like pebbles on the bed of a clear stream. It suits a pool with a light edge, a bathroom and an outdoor shower.

Where it is used

• walls in bathrooms and shower cubicles
• the area above the kitchen worktop with an embossed effect
• accents in spa centres, hotels and restaurants

Glass reflects the light and gives the wall depth, so the covering looks different by day and in the evening.

Key benefits

• Non-porous: water absorption is up to 0.04 %, so the glass does not grow mould, absorb stains or hold odours.
• Lasting colour: it fades neither in sunlight (ISO 4892) nor from cleaning agents (class A per ASTM C650).
• Indoors and outdoors: withstands freeze-thaw cycles per ASTM C1026.
• Strength: flexural strength 55 N/mm² and a defect-free surface per EN ISO 10545-2.
• Silicone backing: the sheet is flexible and follows curved walls, steps and corners.
• Eco-friendly material: 100 % recycled glass, with no lead or cadmium pigments and no heavy metals.

Technical specifications

Silicone dot backing instead of mesh or paper

Small silicone (polyurethane) dots join the chips at the back without covering it. Over 95 % of each chip stays free for the adhesive, and the bond is very strong. The backing does not change the height of the mosaic, withstands contact with adhesive and grout, and does not warp while the sheets sit in storage.

• Adhesive: with dots, the adhesive reaches over 95 % of the back of the chip; mesh covers part of it, and with paper the adhesive touches the whole back, but the chips are covered at the front.
• Control during laying: with the silicone backing the chips and joints stay visible the whole time, whereas paper hides them.
• Curves and corners: the flexible silicone sheet bends most easily; a paper sheet tears.
• Finally: with dots there is nothing to remove, whereas paper has to be soaked and peeled off.

Choosing the grout

White grout preserves the light look, while dark green grout makes the chips stand out more. In a shower and under constant moisture, choose epoxy grout or a water-resistant class C2 grout; it does not absorb water and keeps its colour.

How to install

1. Substrate preparation: the surface must be level (deviation of up to 2 mm over 2 m), dry, sound and dust-free. In the shower area, waterproofing is applied first.
2. Adhesive: white flexible cement-based adhesive C2TE S1. The white colour matters because the glass is partly transparent and a grey adhesive would dull it.
3. Application: using a 3–4 mm notched trowel, cover an area for 2–3 sheets.
4. Laying: press the sheet evenly with a rubber float and keep the same 2 mm joint between the sheets.
5. Cutting: where a sheet has to be shortened (corners, nozzles), the dots are cut through with a utility knife, and a single chip is nibbled off with glass mosaic nippers.
6. Grouting: wait a day. Remove excess grout with a damp sponge while it is still soft; epoxy grout is cleaned straight away with a special cleaner.
7. Putting into use: water may run only once the grout has fully hardened.

Prepare the tools as well: a notched trowel and a rubber float, a utility knife, special glass mosaic nippers, a sponge and a bucket of clean water.

How much material to plan for

Calculate the area as height × width for each wall and add an allowance for cutting waste. The approximate adhesive consumption is 2 kg/m² for chips up to 25 mm, 2.5 kg/m² for 40 mm and 3 kg/m² for larger ones; for the grout use the formula (A + B) / (A × B) × C × D × 1.6 kg/m², where for this model the chip is 25 × 25 mm, the thickness is 4 mm and the joint is 2 mm. In practice the quantity varies with the condition of the substrate, the chosen materials, the trowel notch size and the skill of the installer – check it against the technical data sheets of the adhesive and the grout.

Laboratory tests

• UV exposure (ISO 4892): the colour remains unchanged.
• Thermal expansion (EN ISO 10545): the material withstands it.
• Surface (EN ISO 10545-2): all chips are free of defects.
• Water absorption (EN ISO 10545-3): 0.04 % at most.

Care of the covering

• Clean with a soft cloth or sponge and a neutral cleaner.
• Avoid abrasives, wire brushes and acidic cleaners, which damage the grout.
• A rubber squeegee after showering leaves the glass free of drops and stains.

Quantities and batch

The mosaic is sold in multiples of a 1 m² carton. Buy everything at once and add 5–10 % extra – this way the sheets come from one batch and the shade is uniform. It can also be laid over old tiles if they are sound, clean, degreased and primed with a suitable primer.

Colour in photos and in reality

Glass mosaic is perceived differently depending on the screen, the light, the viewing angle, the water in the pool, the colour of the grout and adhesive, the surrounding surfaces and the production batch. A difference between the photos and the actual appearance is therefore possible. The visualisations are illustrative.
