Thinset is a type of adhesive mortar used primarily for setting tiles. It is made from a mixture of cement, fine sand, and water-retaining agents, which help it bond well to surfaces. Thinset is commonly used in both indoor and outdoor applications, making it versatile for various tiling projects. This adhesive is applied in a thin layer, allowing for quick drying and easy adjustments during installation. Thinset is suitable for different types of tiles, including ceramic, porcelain, and natural stone, and is often used in conjunction with a trowel to create an even surface for tile placement.
