Hand-finished, built to be inherited
Create a striking, contemporary look in your home or business with our Tessera Black & Grey mosaic wall tiles. Designed to replicate the deep, dramatic tones of an industrial slate finish, these panels offer an impactful design statement for modern interiors. The dark grey and black accents add rich depth and character to your walls, providing a premium aesthetic without the need for specialist tools or messy grout.
Each self adhesive mosaic sheet features a highly detailed brushed metallic and stone effect finish, carefully arranged in staggered slate effect strips. Crafted with a 2mm thickness, these metallic mosaic tiles are specifically designed to help conceal minor surface imperfections on the wall underneath, which might be visible with thinner alternatives. The wipe-clean surface ensures low maintenance day to day, requiring just a damp cloth and mild detergent to keep the dramatic black and grey finish looking pristine.
These versatile peel and stick tiles are an excellent choice when you need quick, low-maintenance kitchen splashback tiles, or for updating feature walls, salon interiors, and modern apartments. Sold in convenient packs of ten, each pack provides approximately 0.9m² of coverage with individual sheets measuring 30cm by 30cm. The lightweight panels are easy to cut and require a simple peel-and-stick application over clean, flat surfaces such as smooth painted gypsum, acrylic panels, or glass. If you prefer a different accent tone, the Tessera range is also available in Black & Gold and Black & Silver.
Select the perfect number of packs for your upcoming project, with UK mainland delivery included in the price when you purchase your Tessera self adhesive wall tiles directly at GalaxiMart.

Frequently Asked Questions
What surfaces can I apply these peel and stick tiles to?
For the best adhesion, apply the tiles to flat, clean, and smooth surfaces such as painted gypsum, glass, acrylic wall panels, or smooth ceramic tiles. They are not recommended for uneven brick, bare plasterboard, unpainted plywood, or oily walls.
Are these self-adhesive mosaic tiles suitable for wet areas?
The tiles are water and steam resistant once fully bonded, making them ideal for kitchen splashbacks. However, they are not suitable for direct wet areas like shower cubicles, and they should be kept away from direct heat sources such as gas hobs.
Is delivery included in the price?
Yes. Every price on this page includes UK mainland delivery, charged per pack and already built into the price you see.

Marble
Wipe with a soft, damp cloth and a pH-neutral cleaner. Re-seal every 6–12 months to maintain the finish. Avoid acidic liquids such as lemon juice or vinegar — blot spills immediately.
Ceramic
Heat and scratch resistant for everyday use. Wipe clean with a damp cloth and mild detergent. Avoid abrasive scourers that could dull the surface.
Wood
Use coasters and placemats to protect the surface. Wipe spills promptly with a dry cloth. Polish periodically with a suitable wood oil and keep out of prolonged direct sunlight to prevent fading.
Velvet
Brush the pile gently in one direction and vacuum on a low setting. Blot spills immediately — never rub — and keep out of direct sunlight.
PU Leather
Wipe clean with a soft, damp cloth. Avoid harsh chemicals, solvents and abrasive cleaners. Keep away from direct heat and prolonged sunlight.
