Jointing mortar is a specialized mixture used to fill the gaps or joints between paving stones, bricks, or tiles. It serves both decorative and functional purposes by providing stability to the structure while preventing weeds, dirt, and moisture from entering the gaps. Typically made from a blend of sand, cement, and sometimes polymer additives, jointing mortar hardens over time, creating a strong bond between the individual units. There are different types of jointing mortars, such as traditional dry mix, polymer-based, and grout, each offering varying levels of flexibility, durability, and ease of use. Some types are designed for specific applications, like paving or tiling, and may be either applied wet or dry. The mortar can also be weather-resistant, ensuring long-lasting protection against rain, frost, and UV exposure. In summary, jointing mortar ensures the structural integrity and aesthetic finish of paved surfaces, improving their lifespan and performance.
