Finishing plaster is your ticket to smooth, flawless walls and ceilings, giving any room a professional touch. Whether you’re sprucing up your home or tackling a DIY project, mastering finishing plaster is easier than you think with the right tools and techniques.
Dive into our step-by-step guide to transform your space with a seamless, polished look. Let’s get started and make your surfaces shine!
Step 1: Prepare the Surface
Before applying finishing plaster, it is important to ensure that the surface is clean and free of any debris or loose material. Use a scraper or sandpaper to remove any bumps, cracks, or imperfections on the surface.
If the surface is extremely uneven, you may need to use a filler or joint compound to level it out. This step is crucial for achieving a smooth finish.
Step 2: Gather Your Tools and Materials
To apply finishing plaster, you will need a hawk (a flat piece of metal with a handle for holding the plaster), a trowel (a flat, rectangular tool for spreading the plaster), a bucket of water, and the finishing plaster itself.
It is important to use high-quality tools. This will make the application process easier and result in a better finish.
Step 3: Mix the Finishing Plaster
Follow the instructions on the packaging to mix the finishing plaster with water in your bucket. It is important to mix it thoroughly until it has a smooth, creamy consistency. If the plaster is too thick, add more water and if it is too thin, add more plaster.
Step 4: Apply the Plaster
Start by loading your hawk with a small amount of plaster. Hold the trowel at a 45-degree angle and spread the plaster onto the surface in a thin, even layer.
Work in small sections and use long, smooth strokes to avoid leaving ridges or marks. It is important to keep the trowel clean throughout this process by wiping off any excess plaster on the edge of the hawk.

Step 5: Smooth and Level the Plaster
After applying the first coat of plaster, use your trowel for surface smoothing. Hold it flat against the surface and move in a circular motion, lightly pressing down on any bumps or ridges. If necessary, you can wait until the plaster has partially dried before using a damp sponge to further smooth out the surface.
Step 6: Sand and Repeat
Wall finishing plaster may require multiple coats for a perfect finish. Once the first coat is dry, sand down any rough spots or high points and apply a second coat following the same steps as before.
If needed, you can continue with additional coats until you are satisfied with the result. Just be sure to let each coat dry completely before applying another one.
Step 7: Finishing Touches
Once the final coat of plaster is dry, you can add texture or decorative finishes. You might use a sponge for a stucco effect or a trowel to create swirls for an artistic look. You can also paint over the dried plaster to add color and personality to your walls or ceiling.
