Sample Exam Questions

Worked examples for ASCENTIS Vocational Plastering Techniques — try each before revealing the answer

What is the primary purpose of applying a scratch coat in traditional three-coat plastering?

Answer: To provide a key for the subsequent coats to bond to

The scratch coat is the first coat applied to the background. It is scratched with a comb or devil float to create a rough texture, which provides a mechanical key for the next coat (the float coat) to adhere to. The finish coat is for smoothness, and leveling is done with the float coat.

What is the purpose of applying a scratch coat in three-coat plastering?

Answer: To provide a key for the next coat to bond to

The scratch coat is the first coat applied to a wall. It is scratched with a comb or nail to create a rough texture, which provides a mechanical key for the second coat (the brown coat) to adhere to. This ensures a strong bond between coats.

Which of the following is the correct ratio for a standard browning plaster mix for backing coats?

Answer: 1 part cement to 3 parts sand

A common mix for browning plaster (a backing coat) is 1 part cement to 3 parts sand, sometimes with a plasticizer. This ratio provides good strength and workability. Too much cement (1:1) can cause cracking, while too little (1:4) may be weak.

What is the main reason for using a hawk and trowel when applying plaster?

Answer: To hold and apply plaster efficiently with one hand while using the trowel

The hawk is a flat board with a handle underneath, held in one hand to hold a supply of plaster. The trowel is used in the other hand to scoop plaster from the hawk and apply it to the wall. This allows for continuous application without constantly bending down to a bucket.

During the final setting stage of finishing plaster, what does 'troweling up' achieve?

Answer: It compacts the surface and brings a creamy layer to the top for a smooth finish

Troweling up is done when the plaster has begun to set but is still workable. The trowel is used with pressure to compact the plaster, forcing fine particles and moisture to the surface, which creates a dense, smooth, and polished finish. This is essential for a high-quality final coat.

A plasterer is about to skim a newly plastered wall. What should they do first to ensure proper adhesion?

Answer: Dampen the wall with water to control suction

When skimming over a backing coat, the suction of the background must be controlled. If the wall is too dry, it will suck moisture out of the skim coat too quickly, causing it to crack or not adhere properly. Dampening the wall with a brush or spray reduces suction and allows the skim to set evenly. Bonding agents are used on non-porous surfaces, not on fresh plaster.
