Plastering with the Right Tools: A Complete DIY Guide 2026

Plastering a wall is the final step in building a partition or infill wall, unless the construction materials are meant to remain exposed. Plaster is a mortar made of cement, lime, and sand (or just lime and sand) with a good consistency that adheres well to bricks. The application is done with a trowel, taking a limited amount and throwing it against the wall with a sharp wrist flick. Then the plaster must be leveled and skimmed, finally touched up and finished with setting coats. Each step requires specific tools that should be part of any DIYer's kit. Whether you're renovating a room or finishing a new wall, having the right home improvement equipment makes all the difference.

Essential Tools for Plastering a Wall

• Trowel for mixing and plastering
• Float for smoothing and leveling
• Hawk for holding mortar
• Sponge float for smoothing finishing coats
• Putty knife for small repairs

Trowel

Usually triangular with a rounded tip. The special right-angle handle allows the mason to forcefully throw a modest amount of mortar against the wall. A quality trowel is a staple in any home improvement toolbox.

Hawk

It is a square board made of wood, metal, or plastic with a bottom handle. It is used to hold a certain amount of mortar for application to the wall with the trowel. For larger projects, consider adding a storage bench to keep your tools organized.

Float

The plaster thrown with the trowel against the wall is smoothed and leveled with various passes of the float. The surface of the tool should be wet to prevent it from sticking to the mix.

Metal Hawk

With the metal hawk, you apply mixes and finishing coats "by pass." The amount to be spread is placed on the blade, which is passed over the wall, releasing a uniform layer of mix.

Sponge Float

Fine-grained finishing coats require prolonged smoothing with this tool. The wet sponge hydrates the surface and smoothes it very evenly. After plastering, proper lighting can highlight the texture of your work.

Putty Knife

Useful in many situations for removing excess, smoothing irregularities, and spreading small amounts of mix where cracks or fissures appear. Ideal for finishing. Pair it with wall decor to complete your room's look.

Useful Tips

Some rustic finishes are achieved with a chiocciola (a small container where the mix is inserted); turning the handle spreads the plaster in a circular pattern. For outdoor plastering projects, check out garden supplies to manage your workspace.

FAQ

What is the best tool for applying plaster?

The trowel is the primary tool for throwing plaster onto a wall. A hawk is used to hold the mortar while working.

How do I smooth plaster after application?

Use a float for initial leveling and a sponge float for final smoothing and finishing coats.

Can I plaster over old paint?

It's not recommended. Old paint should be removed or roughened to ensure proper adhesion. Consider using home improvement tools to prepare the surface.

What type of plaster should I use for bathrooms?

Use a waterproof or cement-based plaster in damp areas like bathrooms. Complete the space with bathroom vanities for a cohesive look.

How long does plaster take to dry?

Drying time varies from 24 hours to several days depending on thickness, humidity, and ventilation. Use outdoor heating or dehumidifiers to speed up the process in cold climates.
