5.1 Recommend the ratio that will be used to obtain a smooth plaster finish for interior walls, using one bag of cement - NSC Civil Technology Construction - Question 5 - 2023 - Paper 1

1. Clean the Surface: Remove any debris or foreign materials from the concrete surface to ensure proper adhesion.

2. Moisten the Concrete: Lightly dampen the concrete surface to prevent excessive absorption of water from the screed mix.

3. Apply Bonding Agent: Use a bonding agent to enhance the grip between the screed and the concrete base.

Monolithic screed refers to a type of screeding process where the screed is applied in a single, continuous layer. This method allows for a seamless finish that is more durable and reduces the chances of cracks and delamination.

1. Prepare the Surface: Ensure the stop end is clean and free of dust or loose material.

2. Apply a Bonding Agent: Spread a suitable bonding agent to ensure good adhesion of the plaster.

3. First Coat Application: Apply the first coat of plaster to the stop end, making sure to fill any gaps effectively.

4. Smooth the Surface: After the first coat has set, smooth the surface using a plastering tool.

5. Final Coat: Apply a final coat of plaster for finishing, ensuring that it is even and blends with the surrounding wall.

1. Aesthetic Appeal: Gauged arches provide a more refined and visually appealing finish compared to rough arches, making them suitable for architectural features.

2. Structural Integrity: The use of wedge-shaped bricks in gauged arches ensures a more stable and load-bearing structure, reducing the risk of failure.

The sketch should illustrate half of the wooden turning piece with the appropriate dimensions, showing the curves for the semi-circular arch and indicating the open laggings.

Refer to the provided answer sheet and accurately depict the two consecutive brick courses, ensuring they are aligned properly according to English bond specifications.
