Finishing Cement hard finish requires adding binders in which ratio?

• A. 3:1
• B. 1:3
• C. 1:1
• D. 2:1

Answer: (A)

To get a hard finish, the binder combination should favor cement, since cement provides the early strength and hardness that define a hard surface. A mix with three parts cement to one part lime gives a dense, durable finish: the cement sets quickly and hardens well, while the lime adds some workability and helps control shrinkage cracks without compromising too much on strength. If there’s too much lime (for example, a 1:3 ratio), the surface becomes softer and slower to gain full hardness. Balanced ratios like 1:1 or 2:1 would not deliver the same level of hardness and durability as the 3:1 mix.
