Tile adhesive is a strong bonding material used to fix tiles onto surfaces such as walls and floors. It provides a durable and long-lasting hold while helping to prevent tiles from shifting or lifting. Tile adhesive is usually available in powder or ready-mixed form and is applied with a trowel. It works on a variety of surfaces including concrete, cement screed, plaster, and drywall. The adhesive ensures proper alignment and spacing of tiles and is suitable for both interior and exterior applications depending on the type.
