Definition & Meaning of "grout bag"

What is a "grout bag"?

A grout bag is a tool used to apply grout, a mixture of cement, sand, and water, into narrow joints between tiles. It is similar to a piping bag used in baking, with a thick, flexible bag and a nozzle at one end. The bag allows for controlled, precise application of grout into the spaces between tiles, making the process cleaner and more efficient. Grout bags are commonly used in tile installation, especially for intricate or detailed grout lines. After the grout is applied, the bag can be cleaned and reused for future projects.
