What tool is used to shape, waterproof, and beautify mortar joints in masonry?

• A. Hammer
• B. Jointer
• C. Trowel
• D. Saw

Answer: (B)

The jointer is specifically designed for shaping, waterproofing, and enhancing the appearance of mortar joints in masonry work. When masons finish laying bricks or stones, the mortar joints need to be finished properly to ensure both aesthetics and durability. The jointer allows the mason to create a uniform joint that not only looks neat but also helps to prevent water infiltration by creating a concave, beveled, or flat joint profile, depending on the type of jointer used. Using a jointer also compresses the mortar in the joint, which can help to strengthen it over time. This tool is fundamental in achieving a professional finish and ensuring that the masonry work is not only structurally sound but visually appealing.
