Wall Mosaic

Technical considerations when choosing mosaic for wall applications

Mosaic tiles are a highly versatile and decorative solution for vertical surfaces, especially in bathrooms, kitchens, and wet areas. Unlike floor tiles, wall mosaics are not exposed to high mechanical loads, but they must still meet important technical criteria related to moisture, adhesion, weight, and compatibility with the substrate.

First, the wall surface must be clean, level, dry, and structurally sound. In bathrooms or areas subject to moisture, a proper waterproofing system is essential before installation. This can include liquid membranes or waterproof boards compliant with industry standards.

The type of adhesive depends on the tile material and setting. For dry, interior walls, a ready-mixed adhesive may be suitable. In wet zones, it's crucial to use a flexible cement-based adhesive (C2 classification or higher) for strong, long-lasting bonds.

Lastly, grouting plays both a technical and aesthetic role. For wet areas, we recommend water-repellent or epoxy-based grout to prevent moisture infiltration, stains, and mould. Grout joints are typically between 2 and 3 mm, depending on the mosaic format and pattern.
