Which tool is used to spread or smooth plaster on a wall?

• A. Spatula
• B. Trowel
• C. Putty Knife
• D. Paint Roller

Answer: (B)

The tool that spread and smooths plaster on a wall is the trowel. A trowel has a flat steel blade and a handle, specifically designed to spread plaster evenly and then smooth it to a uniform finish. When you apply plaster, you scoop it onto the wall and use the trowel at a slight angle to push and pull the material, filling gaps and creating a smooth surface. Finishing trowels have even smoother blades for the final passes to reduce marks and achieve a slick coat. Other tools aren’t as suited for this job. A spatula or putty knife is better for small patches and filling minor imperfections, not for covering larger areas smoothly. A paint roller is designed for applying paint and would leave texture or uneven thickness on plaster, not the refined finish you get with a trowel.
