A Complete Guide to Wall Plaster: Types, Techniques & Finishes

23, June 2025

Your walls do more than just divide space—they shape how a room looks, feels, and endures over time. And behind every smooth, beautiful wall lies a layer that rarely gets the attention it deserves: wall plaster. Choosing the right plaster and knowing how to apply it can make all the difference between walls that crack and stain—and walls that remain strong, smooth, and stunning for years.

Let’s dive into the world of wall plaster and uncover its types, application techniques, finishes—and a smart, time-saving alternative for the modern builder.

What is Wall Plaster?

Wall plaster is a protective and decorative coating applied over masonry surfaces to create a smooth or textured finish. It plays a crucial role in sealing the surface, leveling undulations, and providing a clean canvas for paint or wallpaper. Beyond aesthetics, a good plaster job enhances wall durability, thermal insulation, and moisture resistance.

Traditionally, plaster was mixed and applied manually, but newer options like ready mixed plaster are changing the game with greater consistency, ease of use, and reduced application time.

Types of Wall Plaster

Understanding the different kinds of plaster is key to choosing the right one for your project:

• Cement Plaster

 A mix of cement and sand and water; this type is commonly used for exterior walls. It provides strength and durability but requires skilled labor and precise curing to prevent cracks.

• Gypsum Plaster

Gypsum-based plaster sets quickly and is ideal for interiors. It's lightweight, has good insulation properties, and does not require water curing but is not water resistant.

• Lime Plaster

 A traditional material, lime plaster is breathable and eco-friendly. It offers excellent workability and is especially used in heritage restoration projects.

• Ready Mixed Plaster

 A game-changer in modern construction, ready mixed plaster comes pre-blended with polymers, additives, and fine fillers. This ensures uniform quality and simplifies on-site application and is also water-resistant.

• Water-Resistant Plaster

Water-resistant plaster is specifically formulated to resist water and moisture, making it an ideal option for damp-prone areas like bathrooms and basements. By incorporating specialized additives, this plaster enhances its ability to repel water, effectively preventing moisture damage and inhibiting mold and mildew growth.

Techniques of Applying Plaster

Applying plaster isn’t just a manual job—it’s an art form that balances timing, consistency, and finesse. Here are the typical steps followed by professionals:

1. Surface Preparation

 Before anything else, the wall must be cleaned of dust, oil, and loose particles. Any cracks or holes should be patched.

2. Applying a Bonding Agent or Splash Coat

 For smooth or non-absorbent surfaces, a bonding coat (such as cement slurry or chemical bonding agent) is applied to improve adhesion.

3. Mixing the Plaster

 For site-mixed plaster, achieving the right consistency is crucial. Too thick, and it becomes hard to spread; too thin, and it will sag or crack. Ready mixed plaster eliminates this uncertainty by offering pre-set consistency.

4. Application

 Plaster is applied in layers. The base coat (also called the scratch coat) is spread evenly, followed by a second coat for leveling. The final coat smoothens the surface.

5. Curing

Cement-based plaster requires curing with water for 7–10 days to prevent cracks.  Ready mixed plasters like Birla White Levelplast often skip this step.

Types of Plaster Finishes

The finish you choose plays a big role in the final appearance and maintenance of your walls. Here are the most popular options:

• Smooth Finish

 Achieved by troweling and polishing the plaster until it becomes silky smooth. Ideal for interiors where painting or wallpaper is planned.

• Sand Faced Finish

 A rough texture created by adding sand to the final coat. Suitable for exteriors as it helps hide minor imperfections.

• Textured Finish

 Created using tools like sponges, brushes, or rollers while the plaster is still wet. This finish adds visual interest and is often used in feature walls.

• Pebble Dash or Roughcast Finish

Common in traditional exteriors, this finish involves throwing small pebbles onto wet plaster to create a coarse surface.

• Stucco Finish

 A decorative plaster finish with layers that can be tinted and molded to create intricate designs—popular in Mediterranean or colonial-style architecture.

Why Opt for Ready Mixed Plaster?

Traditional plastering can be messy, labor-intensive, and inconsistent. Enter ready mixed plaster—a modern alternative that saves time, reduces waste, and improves quality. It’s especially beneficial in large-scale projects where speed and uniformity matter. Plus, it cuts down on on-site mixing errors, leading to a more predictable and superior wall finish.
