Understanding the differences between drywall and solid wall plastering is essential for construction or renovation projects. Both methods are widely used in modern construction but have unique characteristics that make them suitable for different applications.

Whether you are a homeowner, a contractor, or simply curious, this article will help you explore the advantages and disadvantages of drywall and solid wall plastering, allowing you to make a well-informed choice for your project.

Let’s dive into details about both methods, materials, installation processes, and practical benefits.

Let’s get straight to the point.

Drywall and solid wall plastering are two common methods for building interior walls, each with pros and cons. Drywall, made from gypsum, is affordable, quick to install, fire-resistant, and easy to repair but less durable. It is prone to moisture damage and easily cracks at seams.

On the other hand, solid wall plastering offers exceptional durability, a polished finish, superior soundproofing, and fire resistance, but it is more expensive, labour-intensive, and harder to repair. The choice between the two depends on cost, installation time, durability, and specific project needs.

What Is Drywall?

Drywall, commonly called plasterboard, gypsum board, or wallboard, is a popular building material for creating interior walls and ceilings. The drywall core is made from gypsum, a mineral known for its fireproofing and soundproofing qualities. This gypsum core is layered between two thick sheets of paper, which provides the panel with stability and ease of installation.

Installation Process

Drywall installation is a relatively straightforward process. First, the panels are cut to fit the dimensions of the walls or ceilings. They are then secured to the structure with nails or screws. After the panels are in place, the seams are covered with a joint compound called drywall mud. Once the compound dries, the surface is sanded to create a smooth finish, ready for painting or other decorative treatments.

Common Uses

Drywall is widely used in residential and commercial buildings due to its affordability, versatility, and ease of installation. It is available in various thicknesses to accommodate different needs, with 0.5 inches (12.7 mm) being the most common. Thicker varieties are also available for enhanced soundproofing or additional strength.

Advantages Of Drywall

1. Cost-Effective
   • Drywall is one of the most economical options for creating interior walls. Its low cost makes it an attractive option for large construction or renovation projects.
2. Quick and Easy Installation
   • Since drywall panels are pre-cut, installation is quick and requires less labour. Applying joint compound and sanding is a relatively simple process that speeds up the project.
3. Versatility in Design
   • Drywall provides a smooth, flat surface that can be easily painted, wallpapered, or decorated, giving homeowners a wide range of customisation options.
4. Fire-Resistant
   • The gypsum core in drywall offers natural fire resistance, making it a safer option for interior walls and adding an extra layer of protection against fire hazards.
5. Soundproofing and Insulation
   • Drywall offers decent soundproofing and thermal insulation, which helps maintain a comfortable indoor environment by reducing noise and retaining heat.
6. Ease of Repair
   • The drywall can be easily repaired. Small holes and cracks can be patched with joint compounds, and larger sections can be replaced if necessary.

Disadvantages Of Drywall

1. Vulnerability to Moisture
   • Standard drywall is not moisture-resistant, making it susceptible to damage in humid areas like bathrooms and basements. While moisture-resistant drywall is available, it is more expensive and may not fully resolve issues in wet environments.
2. Limited Durability
   • Drywall is more prone to damage from impacts or moisture than solid wall plastering. It can easily dent or puncture, making it less durable in high-traffic areas.
3. Heavy Panels
   • Drywall panels, especially larger ones, can be quite heavy. Installation may require extra hands or specialised equipment to maneuver them into place.
4. Potential for Cracks at Joints
   • If not properly finished, the joints between drywall panels are susceptible to cracking. These cracks may become more visible over time, especially in areas prone to structural movement or moisture.

What Is Solid Wall Plastering?

Solid wall plastering is an older construction method that involves applying a mixture of cement, sand, and water directly onto masonry or concrete walls. This technique has been used for centuries and is known for its durability and polished finish. It can be used for interior and exterior walls, offering excellent insulation properties and a long-lasting surface.

Application Process

The application process for solid wall plastering is labour-intensive and requires several layers of plaster to be applied in stages. First, a rough base coat is applied to the wall. Additional layers are added as the plaster sets, creating a smooth finish. Depending on the thickness of the plaster and the weather conditions, it can take several days to dry completely.

Common Uses

Solid wall plastering is often used in older buildings, high-end construction projects, or homes that require long-lasting finishes. Its durability and ability to provide a smooth surface make it ideal for areas that demand higher quality.

Advantages Of Solid Wall Plastering

1. Exceptional Durability
   • Once applied, solid wall plastering creates a dense, hard surface more resistant to wear and tear than drywall. It’s a great option for high-traffic areas where durability is essential.
2. Smooth and Polished Finish
   • Solid wall plastering offers a seamless and highly polished finish that surpasses drywall in aesthetic appeal. The absence of seams between panels ensures a flawless appearance without weak points where cracks could develop.
3. Fire Resistance
   • Like drywall, solid wall plastering is fire-resistant due to its cement-based composition, providing extra safety for your building.
4. Superior Soundproofing
   • Thanks to its dense structure, solid wall plastering offers excellent soundproofing capabilities, making it an ideal choice for spaces that require noise reduction, such as recording studios or offices.
5. Mould-Resistant
   • Plaster is naturally resistant to mould and mildew, which makes it suitable for humid environments such as kitchens or bathrooms.

Disadvantages Of Solid Wall Plastering

1. Higher Installation Costs
   • Solid wall plastering is significantly more expensive than drywall due to the higher cost of materials and the labour required for installation. Skilled workers are often needed to ensure a smooth and even finish.
2. Time-Consuming Installation
   • Unlike drywall, which can be installed in a matter of days, solid wall plastering can take up to a week or more to apply and dry. This extended timeline can slow down the overall construction process.
3. Difficulty in Making Repairs
   • If solid plaster walls are damaged, repairs can be difficult and costly. Fixing a crack or hole often requires removing and replacing large sections of the plaster, which is more labour-intensive than patching drywall.
4. Limited Design Flexibility
   • While solid wall plastering offers a smooth finish, it is less flexible than drywall for design modifications. Making structural changes or adding features to plastered walls is more challenging.
