    Dry lining and plaster are two of the most popular ways to finish off the walls within a building. The dry lining was introduced in the 1900s as an alternative to plaster, which had been the more common method of wall finishing throughout history.

    The dry lining has gained popularity since then, and many contemporary homes now feature it instead of plaster. However, the many available choices can make it difficult for consumers to select the best finish for their home or property for a variety of reasons that we'll examine below.

    For that reason, we have compiled this manual. To aid in your decision regarding the most appropriate approach, we will compare and contrast dry lining with wet plastering below.

    Wet Plastering

    Skilled plasterers frequently employed the method of wet plastering before the advent of plasterboard. Because of its durability, this choice was once favoured by homeowners of older homes and remains a popular option today.

    The walls are plastered from top to bottom without using any plasterboard. Its high adhesion guarantees a complete seal between the materials and the walls. The plaster is then smoothed out for a durable, long-lasting appearance. The ceilings and walls might be plastered with the same solid material.

    Wet plastering, however, does have a few drawbacks.

    Plastering is a labour-intensive process that can take several days, depending on the weather. When factoring in the price of materials and labour, wet plastering is also typically more expensive than alternative methods.

    Wet plastering is the method of choice when restoring older structures or when a superior finish is required. It works especially well on ceilings and walls that need repairing or have irregular surfaces.

    Advantages Of Wet Plastering

    Consider some of the advantages of using wet plastering:


    When plastered while still wet, a surface becomes extremely durable. Once the plaster has dry and set, it makes a strong bond with the substrate below it, increasing the building's longevity and steadiness. In addition, it is durable enough to withstand regular use and is resistant to damage such as cracking.


    The versatility and creative potential of wet plastering cannot be overstated. Skilled plasterers can add visual interest and character to a room by constructing custom textures, patterns, and mouldings. You can put your stamp on things and come up with something special that way.

    It Allows You To Meet Fire Standards

    Wet plastering's fire resistance is a major selling point for homeowners deciding between it and other options. Plastering the walls with water in the event of a fire is an often-overlooked safety measure that might determine whether or not someone lives or dies.


    Damages and flaws in wet plaster are simple to fix. It can be repaired by patching, smoothing, or replastering to make it look new since only the damaged area needs to be replaced rather than the whole thing, this is a better deal financially in the long run.

    It Prevents Noise From Entering

    One of the best parts about this method is that it improves soundproofing compared to dry-lined walls. This is because it's thick, and it reflects noise very well. Because of this, the acoustic quality of a room is maintained at a high level.

    It Has A Great Smooth Appeal

    Plaster is the best material for a smooth, professional look. Its superior aesthetic quality is guaranteed by its silky smooth texture. Once the surface has dried slightly, painting can begin.

    Wet-plastered walls look great and are ready to be painted anytime, so there's no rush to do so during renovation.

    Disadvantages Of Wet Plastering

    Although there are many benefits to using wet plastering, there are also some drawbacks to think about. The primary problems with wet plastering are as follows:

    Drying Time

    Painting or decorating can only be done on wet plaster once completely dried. Plaster can take several days or weeks to dry completely, depending on the humidity level and the thickness of the material. This may impact the overall construction schedule.

    Cleaning Up The Mess

    Creating and applying a wet plaster mixture can be a messy process. Cleaning up the resulting debris, dust, and splatters may be necessary. In addition, plaster waste must be properly disposed of, which can add time to the cleanup process.

    Less Modification Flexibility

    When wet plaster dries and cures, it becomes difficult to make alterations to the wall or ceiling. It is necessary to do more extensive work and damage the existing plaster if additional plumbing, wiring, or structural alterations are to be done. In addition, this rigidity can make it difficult to make necessary alterations or upgrades in the future.


    Wet plastering is a complex and time-consuming process that calls for experts. In addition, wet plaster can take a long time to apply, dry, and cure, especially in larger areas. This may cause the project to run over budget and behind schedule.

    Higher Cost 

    Compared to alternative wall and ceiling finishing options, wet plastering is typically more expensive. The price reflects the supplies and the expert labour needed for installation. Additional expenses stem from the potential requirement for specialised tools and equipment.

    Application Is Limited To Dry Areas

    Plastering that is applied while wet cannot be used in constantly wet rooms, such as bathrooms and wet rooms. Plaster that has been damaged by moisture may eventually deteriorate or develop mould. Dry lining or tiling are two alternatives that can be used in this situation.

    Risk Of Cracking

    While a wet plaster finish can be strong, it is not completely crack-proof. Plaster cracks can develop for various reasons, including building settlement, temperature fluctuations, and vibrations.

    However, the likelihood of cracking can be reduced with regular maintenance, preventative measures, and the correction of underlying structural problems.


    Drylining begins with the plasterboards being cut to size and shape for the walls. Next, they are attached to a wooden framework at the future wall's location. Then, the seams, walls, and crevices are taped with fibreglass mesh.

    The wall is then provided with three coats of joint compound to smooth it out and prepare it for painting. Wet plaster skimming is much more common than the joint and tape method because it leaves a smoother finish.

    Advantages Of Drylining

    Dry lining, also known as drywall installation, is common in the building industry due to its many benefits. The primary advantages of dry lining are as follows:


    When compared to wet plastering, dry lining typically has lower costs. This is because dry lining materials, like plasterboard and fixing accessories, are cheap and easy. In addition, due to the reduced need for labour, it is a more cost-effective option for new construction or renovations.

    Moisture Resistance

    Plasterboard that can withstand high moisture levels is available in moist environments like bathrooms and kitchens. These gypsum panels are treated to resist moisture and mildew growth. Dry lining provides a functional answer for damp areas without sacrificing design or longevity.

    Decoration Ease

    Dry lining creates a blank canvas on which to paint or hang wallpaper. Plasterboard is simple to install and even simpler to decorate with paint, wallpaper, or other options. The uniformity of the surface texture guarantees a polished appearance and frees up design options.

    Modification Flexibility

    Dry lining facilitates upcoming alterations and modifications. Plasterboard is simple to modify, remove, or replace to accommodate alterations to the building's electrical, plumbing, or other systems. Since dry lining can be easily modified in the future, it's a sensible option for potentially changing uses.

    Speed And Efficiency 

    Dry lining is a more efficient alternative to wet plastering. It is not necessary to apply wet plaster or wait for it to dry before installing plasterboard sheets on a wall or ceiling. As a result, labour costs, both in time and money, can be reduced.

    Versatility And Installation Ease

    Dry lining can be applied to many different materials, including masonry, metal stud walls, and wood frames. It's a versatile approach that works well with various architectural styles. When compared to wet plastering, the installation process is straightforward and necessitates fewer specialised skills, making it available to a wider range of construction professionals.

    Improved Insulation

    When walls and ceilings are dry-lined, they become more energy efficient and quieter. In addition, it is possible to improve heat retention and soundproofing by inserting insulation materials like mineral wool or foam boards into the space between the plasterboard and the wall. This aids in reducing utility costs and making a space more pleasant to spend time in.

    Minimal Disruption

    Dry lining is a low-mess method of construction. Unlike traditional wet plastering, very little dust and debris are produced during installation. Thus, it finds application in new builds and remodels where a sanitary workplace is a priority, thus reducing cleaning time and occupant inconvenience.

    Disadvantages Of Dry Lining

    There are some disadvantages to dry lining that must be weighed against its benefits. Some disadvantages of dry lining include the following:

    Considerations For The Environment

    Plasterboard, used in dry lining, is manufactured from gypsum, a nonrenewable resource. As a result, Plasterboard can have negative effects on the environment during both its production and disposal. To lessen the damage done to the environment by dry lining, it is essential to implement eco-friendly measures like recycling and waste reduction.

    Imperfections On The Surface

    Surface flaws or structural irregularities may become more noticeable after being dry-lined. For example, Plasterboard joints and bumps may be more obvious on uneven walls and ceilings. A smooth and even finish can only be created by properly preparing the surface, which may involve levelling or skim coating.

    Moisture Susceptibility

    It is possible to find plasterboard resistant to moisture, but moisture damage is common in typical dry-lining materials. Therefore, providing adequate moisture barriers and ventilation systems is important to minimise moisture seepage, mould growth, and plasterboard deterioration in high-humidity rooms like bathrooms and kitchens.

    Lower Soundproofing

    When compared to wet plaster, the soundproofing provided by dry lining is only slightly better. Although it does dampen sound somewhat, it may not be as effective as multiple layers of wet plaster at reducing or eliminating noise. Therefore, optimal acoustic performance can only be achieved by including extra soundproofing measures such as insulating materials.

    Difficulties In Repair

    Plasterboard damage repair can be more difficult than wet plastering in some cases. Removing and replacing an element is possible if the damaged region is a significant enough sheet of plasterboard rather than just the damaged section. However, particularly in areas with restricted access or those with intricate finishes, this can add unnecessary expenses and cause disruptions.

    Fire Resistance Is Lower

    Plasterboard and other dry-lining materials are less fireproof than wet plaster. Fire-resistant plasterboard exists; however, it may not be as effective as wet plaster in protecting against flames and high temperatures. Therefore, additional fireproofing measures may be needed to meet specific fire safety regulations.

    Design Flexibility Is Limited

    When compared to wet plastering, dry lining severely restricts interior design options. Wet plaster's smooth and seamless finishes are often more adaptable to creating complex patterns, textures, and bespoke designs. However, due to its foundation in prefabricated plasterboard sheets, the dry lining may limit your ability to express yourself creatively.

    Reduced Durability

    When compared to wet plastering, dry lining typically has a shorter lifespan. Dry lining requires plasterboard, which can be easily broken by bumps or soaked through by too much humidity. In high-traffic areas or anywhere else where impact resistance is essential, it may not hold up as well as wet plaster.

    Factors To Consider

    Wet plastering and dry lining each have advantages and disadvantages that must be weighed when a building or remodelling project is planned. Considering these aspects, you can zero in on a strategy that best fits the needs of your project. Here are the most crucial considerations:

    Building Standards And Regulations

    Know the local construction codes and standards that will affect your project. Depending on where you live, you may need to adhere to standards like wall and ceiling finishes, fire safety, soundproofing, and moisture resistance. Make sure the approach you take follows all the rules and guidelines that apply.

    Requirements For Noise And Thermal Insulation

    Think about how much sound and heat you want to keep out of the room. Compared to the dry lining, the soundproofing properties of wet plastering are superior. Wet plastering may be the best option if soundproofing is a top priority. Consider the area's thermal insulation requirements and select the best approach to meet those needs so residents can live comfortably.

    Availability Of Skilled Labor

    Think about the accessibility of trained workers in each technique. You need to know what you're doing to get a professional look when wet plastering. Determine if experienced experts in your area are readily available and willing to work with the desired approach. Since dry lining requires less specialised knowledge, it could be easier to find qualified workers.

    Project Specifications And Requirements

    Determine how your project will be affected by each of these factors. Consider the building's function ( residential, commercial, etc.), desired aesthetics, and practical needs. Determine if the dry lining or wet plastering would be more suitable for fulfilling these needs.

    Considerations For Moisture And Dampness

    Determine the humidity level in the room where the wall or ceiling will be installed. Wet plastering is a good option for areas with high humidity or potential water exposure due to its increased resistance to moisture. However, to address moisture and dampness issues effectively, the dry lining may be paired with other measures, such as moisture barriers or specialised plasterboard.

    Considerations For Budget And Cost

    Consider the financial limitations you face before beginning the project. For example, applying wet plaster requires more time, dedication, and expertise, which can lead to a higher price per square foot. However, dry lining typically saves money because it requires less installation time and materials. Consider your financial constraints and choose the approach that best fits them.

    Flexibility For Modifications

    Think of the chances of changes happening in the near future. For example, renovations to the electrical system, plumbing, or other components are easier to implement when a building is dry-lined. On the other hand, wet plastering can be more difficult to access and modify than dry plastering, and it can potentially damage the current plaster.


    Dry lining and plaster are two common choices for interior wall finishing. Dry lining replaced the more traditional process of using plaster and became popular in the twentieth century. Since then, its popularity has skyrocketed, and many modern homes now use it in place of plaster. However, consumers may struggle to choose the ideal finish for their home or property due to the abundance of options.

    Wet plastering is time-consuming and costly because it requires multiple people working on the project at once and depends on the weather. When repairing older buildings or when a high-quality finish is essential, this is the technique of choice. It's perfect for patching holes in the ceiling or smoothing down bumps in the wall.

    Wet plastering has many benefits, such as its longevity, adaptability, fire resistance, repairability, noise reduction, and sleek aesthetic. Drying time, cleaning up the mess, reduced modification flexibility, prolonged application to dry regions, increased expense, and the possibility of cracking are among of the disadvantages.

    The benefits of dry lining, commonly known as drywall installation, include low costs, resistance to moisture, and simplicity of design. Since dry lining materials are less expensive and simpler to install, they are a more economical choice for building or remodelling projects. It's a practical solution that won't compromise on style or durability, even in humid environments.

    FAQs About Wet Plastering and Dry Lining

    Yes, wet plastering can be used in bathrooms and wet areas. Wet plastering is a method that involves applying a wet mixture of plaster, sand, and water directly onto the walls or ceilings. It can provide a smooth and durable surface that is resistant to moisture. 

    This makes wet plastering suitable for areas prone to high humidity, such as bathrooms, shower areas, or other wet spaces. It helps create a protective layer that can withstand moisture and prevent damage to the underlying structure. However, it's important to ensure proper ventilation and use moisture-resistant materials in conjunction with wet plastering to maintain the integrity of the finish and prevent issues like mould or dampness.

    No, dry lining is not suitable for external walls. Dry lining refers to adding an internal layer of plasterboard or similar materials to existing walls, typically for insulation or aesthetic purposes. It is primarily used for interior walls and is not designed to withstand the weather conditions and external exposure that external walls face. Other methods, such as traditional brick or block construction, rendering, or cladding, are more appropriate for external walls.

    The time it takes for wet plaster to dry can vary depending on various factors, such as temperature, humidity, and the thickness of the plaster layer. Generally, it takes about 1 to 3 days for plaster to dry to the touch. However, the plaster can take up to several weeks to fully cure and reach its maximum hardness. During this curing period, it is important to allow proper ventilation and avoid applying additional moisture to the plaster to ensure a thorough drying process.

    Yes, the dry lining can be used for decorative purposes. Dry lining involves adding an internal layer of plasterboard or similar materials to existing walls, and these surfaces can be further enhanced with decorative finishes. 

    Once the dry lining is in place, it can be painted, wallpapered, or adorned with various decorative techniques such as texturing, stencilling, or adding decorative panels. In addition, dry lining provides a smooth and even surface, making it suitable for creating aesthetically pleasing walls and enhancing a room's overall decor.

    The effectiveness of soundproofing methods depends on various factors, such as the level of noise, the construction of the room, and personal preferences. However, some commonly used methods for soundproofing a room include adding insulation materials, sealing air gaps, using double-glazed windows, and installing acoustic panels or soundproof curtains. 

    The best method for soundproofing a room depends on the specific needs and circumstances of the space. Therefore, combining multiple techniques to achieve the desired level of sound insulation is often recommended. Consulting with a professional or conducting research specific to your situation can help determine the most suitable method for your needs.
