The Mosaic Mall. Mosaic fibreglass mesh in sticky and non-sticky variants, available in red, yellow, and white colours, provides a durable foundation for mosaics, with the white variant offering better transparency. Non-alkaline fibreglass mesh is generally recommended for use in mosaics over alkaline mesh. This is because alkaline mesh can react with the cement in the mortar or grout used to secure the tiles, causing discoloration or even damage to the tesserae.

Non-alkaline mesh, on the other hand, is chemically inert and does not react with the cement, making it a safer and more reliable choice for mosaic projects. It is also less likely to deteriorate over time and is generally more durable. In summary, non-alkaline fibreglass mesh is the recommended choice for mosaics due to its chemical stability, durability, and compatibility with cement-based adhesives and grouts.
