Plastering a wall is essential to achieving a smooth, flawless surface ready for painting or decoration. Whether you are planning on improving internal walls or need external plasterwork done, understanding the time it takes to plaster a wall can help you plan your renovation project effectively. If you are searching for answers or looking for professional plastering services like decorative plasterwork or external plastering and Skimming Services in Durham, this guide will provide you with clear and practical information.
How Long Does It Take to Plaster a Wall?
The time required to plaster a wall depends on several factors, including the wall size, type of plaster, and the plasterer’s expertise. On average, plastering a standard-sized wall (approximately 12m²) can take between 3 to 4 hours for a first coat and an additional two hours for a finishing coat.
Here’s a general breakdown of the process:
- Preparation and Cleaning: 30 minutes to 1 hour
- Application of the First Coat: 2 to 3 hours for a medium-sized wall
- Allowing the First Coat to Set: 1 to 2 hours
- Applying the Finishing Coat: 1.5 to 2 hours
For smaller walls, the total time may decrease, while larger walls or more intricate decorative plasterwork can take longer. If you’re opting for skimming services, the process might extend based on the size and condition of the exterior walls.
What Factors Influence Plastering Duration?
Several variables can affect how long it takes to plaster a wall. Understanding these factors will help you estimate more accurately and better prepare for the project.
- Wall Size and Condition: Larger walls or walls with cracks and imperfections take more time to prepare and plaster.
- Plaster Type: Materials like lime plaster dry slower compared to modern ready-made plasters. Decorative plasterwork may also require additional time for intricate designs.
- Skill Level: An experienced plasterer in Durham may complete the work faster and more efficiently than someone doing it themselves.
- External vs. Internal Plastering: External plastering services can take longer as they often deal with weather-resilient coatings, which may require additional layering and drying time.
- Drying Time: Humidity levels in Durham can affect the drying and curing process, potentially extending project timelines.
Before you start, it’s always wise to consult with professionals to get a precise time frame tailored to your specific project.
How Long Does Plaster Take to Dry?
Plaster typically takes around 4-7 days to dry completely, but timing depends on the type of plaster and environmental conditions. Drying time is longer if you’re working on external plastering or using certain Decorative Plasterwork materials. Factors that influence drying include:
- Room Humidity: Damp or poorly ventilated environments slow down drying.
- Plaster Type: Standard gypsum plaster dries faster than traditional lime plaster or cement-based variants.
- Thickness of Application: Thicker layers naturally require longer drying periods.
While plaster may feel dry to the touch within a couple of days, it’s important to wait for full curing before decorating, particularly when painting as damp plaster can cause paint to peel or bubble.
Why Is Preparation Crucial Before Plastering?

Good preparation ensures that the plaster adheres properly, provides a smooth finish, and lasts longer. Here are the steps required before plastering begins:
- Clean and Repair the Surface: Remove loose old plaster, dust, and dirt. Fix cracks or holes to create a solid base for the plaster.
- Apply a Base or Bonding Agent: Use bonding agents like PVA glue to enhance plaster adhesion on uneven or smooth surfaces.
- Protect Surroundings: Cover floors, windows, and furniture using protective sheets to prevent mess.
- Inspect for Damp or Mold: Address any dampness issues before applying plaster for lasting results.
Preparing your walls ensures efficient application and a flawless finish. If you’re hiring professionals, they’ll handle the preparation seamlessly for you.
How Is Plaster Applied?
Plastering involves a three-step process for achieving a smooth, polished look. While it may look straightforward, the technique requires skill and precision, especially for large walls or intricate decorative plasterwork.
- First Coat Application: The plasterer spreads an even layer over the surface using a trowel. This step focuses on covering all gaps and imperfections.
- Smoothing and Leveling: After the first coat starts to set, the surface is smoothed and leveled for an even appearance.
- Finishing Coat: A thinner, smoother layer is applied for a polished look, followed by gentle polishing to ensure a high-quality result.
If you require skimming services, the method is adapted to ensure all-weather durability and a neat finish.
Can You Plaster Over Old Plaster?
Yes, you can plaster over old plaster, but specific conditions must be met. The existing plaster must be stable, clean, and free of loose or crumbling sections. If the old surface isn’t in optimal condition, a bonding agent may be required before applying new plaster.
For walls in poor shape, professionals may recommend completely removing the old plaster for better results, particularly for external plasterwork where durability is essential.
What Tools Are Required for Plastering?
To achieve professional results, the right tools are key. A skilled plasterer will typically use the following equipment:
- Plastering Trowel: Essential for spreading and smoothing plaster.
- Hawk Board: Used to hold and carry plaster while applying.
- Bucket Trowel: Ideal for scooping plaster from buckets.
- Plastering Float: Helps in polishing the final coat for a smooth surface.
- Mixing Tools: Used to prepare the plaster mix to the right consistency.
Professional plasterers in Durham usually come equipped with everything needed, saving you the hassle of sourcing these tools.
Should You Hire Professionals to Plaster Walls?
Hiring professional plasterers ensures your walls are beautifully and efficiently finished. While DIY plastering is an option, it can often lead to uneven surfaces or cracks later if you’re not skilled in the process. Here’s why professional services are worth it:
- Expert Technique: Skilled plasterers can handle large or intricate projects like decorative plasterwork.
- Time-Efficient: Projects are completed quickly without compromising on quality.
- Stress-Free: Professionals handle everything, from preparation to cleaning up after the job.
