What Are The Tools Needed For Plastering?

Plastering a wall may seem like a daunting task, but with the right tools, it can be a smooth and efficient process. In this section, we will discuss the essential tools needed for successful plastering. From the trusty trowel to the versatile plastering float, we will cover each tool's purpose and how it contributes to achieving a flawless finish. So, let's dive into the world of plastering tools and prepare for a successful project.

1. Trowel

A trowel is a necessary tool for plastering walls. Follow this step-by-step guide on how to effectively use a trowel:

  1. Prepare the wall by thoroughly cleaning it and repairing any damages.
  2. Mix the plaster according to the manufacturer's instructions.
  3. Use the trowel to apply the first coat of plaster, starting from the bottom and working your way up.
  4. Smooth out the surface of the plaster with the trowel to remove any excess and create a seamless finish.
  5. Apply the second coat of plaster, using the same technique as before.
  6. Ensure an even and level finish by smoothing out the surface of the plaster with the trowel.

Remember to clean the trowel after each use to maintain its effectiveness.

2. Hawk

A hawk is a necessary tool when it comes to plastering a wall. It serves as a holder and carrier for the plaster during the process. Here are the steps involved in using a hawk:

  1. Place the hawk securely on your non-dominant hand.
  2. Scoop an adequate amount of plaster onto the hawk using a trowel.
  3. Hold the hawk close to the wall where you will be applying the plaster.
  4. With your dominant hand, take plaster from the hawk and apply it onto the wall using a trowel or plastering float.
  5. Repeat the process, ensuring a consistent and even application of plaster.

Using a hawk allows for better control and maneuverability while plastering, resulting in a smoother and more efficient process.

3. Plastering Float

A plastering float is a necessary tool for the process of plastering walls. Its purpose is to spread and smooth the plaster over the surface, ensuring a professional and even finish.

Here is a step-by-step guide on how to properly use a plastering float:

  1. Begin by preparing the plaster mix according to the instructions.
  2. Scoop a generous amount of plaster onto the float.
