Plastering Frequently Asked Questions

We understand you may have some questions before starting your plastering project with us. To help you make a more informed decision, here are 4 frequently asked questions that have been answered in-depth. For more questions about plastering and rendering see our Frequently Asked Questions page.

Plastering is a skilled craft that involves applying a smooth, durable, and cohesive layer of plaster onto surfaces to create a finished and aesthetically pleasing appearance. The process typically includes the following steps:
Surface Preparation:
Before applying plaster, it's crucial to prepare the surface properly. This involves cleaning the surface of any dirt, dust, or loose particles. If there are existing layers of old plaster, they may need to be removed or repaired.
Application of Plaster Base Coat:
The first layer applied is the base coat, also known as the scratch coat. This coat sometimes consists of a mixture of sand, lime, and cement, creating a strong and stable foundation for the subsequent layers. The base coat is applied evenly and then scratched with a comb-like tool to enhance the adhesion of the next layer.
Application of Plaster Finish Coat:
The finish coat is the final layer that provides the smooth and decorative surface. This coat is a finer mixture of plaster, and it requires precision in application to achieve a flawless appearance. Skilled plasterers use various techniques to create different textures and finishes according to the client's preferences.
Trowel Work:
Trowels, which are flat, pointed tools, are used extensively in plastering. Skilled plasterers employ a combination of techniques such as floating, feathering, and polishing with the trowel to ensure a uniform and attractive finish.
Curing and Drying:
Once the plaster is applied, it needs sufficient time to cure and dry. The curing process is critical for the plaster to achieve its maximum strength and durability. Factors such as temperature and humidity can influence the drying time.
Sanding and Smoothing:
After the plaster has dried, the surface may be sanded to achieve an even smoother finish.
Painting or Sealing:
Depending on the desired final look, the plastered surface may be painted or sealed. This not only enhances the aesthetic appeal but also adds a protective layer to the plaster, extending its lifespan.
It's important to note that plastering is a skill that requires experience and expertise. Professional plasterers have a keen eye for detail and the ability to troubleshoot issues that may arise during the process, ensuring a result that meets both functional and aesthetic expectations.
Plastering serves various functional and aesthetic purposes, making it a valuable and versatile construction technique. Here's a detailed explanation of why plastering is done:
Surface Protection:
Plaster provides a protective layer over walls and ceilings, safeguarding them from external elements such as moisture, weathering, and physical damage. This protection enhances the longevity and structural integrity of the underlying surfaces.
Smooth and Aesthetic Finish:
One of the primary reasons for plastering is to achieve a smooth and visually appealing finish. Plaster allows for the creation of different textures and designs, enhancing the overall aesthetics of interior and exterior spaces. The finish can be customised to meet the specific design preferences of the homeowner or architect.
Enhanced Insulation:
Plastering can contribute to improved insulation by creating a barrier against temperature extremes. The layer of plaster adds a level of thermal resistance, helping to regulate indoor temperatures and reduce energy consumption for heating or cooling.
Fire Resistance:
Plaster is inherently fire-resistant, providing an added layer of safety to structures. In the event of a fire, plaster can act as a barrier, preventing the rapid spread of flames and providing valuable time for evacuation and firefighting efforts.
Structural Stability:
Plastering, especially when applied as a base coat, contributes to the structural stability of walls. It helps in distributing loads evenly and can reinforce weak areas, adding strength to the overall structure.
Repair and Restoration:
Plastering is often employed in the repair and restoration of old or damaged surfaces. It can cover imperfections, cracks, and unevenness, giving a fresh and renewed appearance to walls and ceilings. This is particularly valuable in preserving the historical or architectural integrity of older buildings.
Acoustic Benefits:
Plaster has natural acoustic properties that can help absorb and dampen sound. This is especially beneficial in creating quieter and more comfortable living or working environments by reducing noise transmission between rooms.
Versatility:
Plastering is a versatile technique that can be applied to various surfaces, including brick, concrete, and wood. This versatility makes it a popular choice for both new construction and renovation projects.
Plastering serves a multifaceted purpose, including protection, aesthetics, insulation, and structural reinforcement. Whether for modern design preferences or the preservation of historical structures, plastering remains a fundamental and adaptable component of construction and renovation practices.
If you’re thinking of having a go at plastering a room yourself, preparing a room for plastering is a vital step to ensure a smooth and successful plastering process. Here's a short but detailed guide on how to prepare your room for plastering:
Clear the Space:
Remove all furniture, decorations, and other items from the room. This includes covering floors with protective materials to prevent damage or staining from the plaster.
Protect Fixtures and Fittings:
Cover light fixtures, switches, outlets, and any other fixtures with plastic sheeting or painter's tape to shield them from plaster splatter. This precaution helps in maintaining the functionality and appearance of these elements.
Repair and Clean Walls:
Inspect the walls for any existing damage, such as cracks or holes. Repair these imperfections with patching compound or joint compound. Clean the walls thoroughly to remove dust, dirt, and grease, as a clean surface ensures better adhesion of the plaster.
Remove Wallpaper or Peeling Paint:
If there is wallpaper or peeling paint on the walls, it should be removed to create a smooth and even surface for the plaster. Use a wallpaper scraper or sandpaper to eliminate any existing coverings.
Apply a Bonding Agent:
Before plastering, applying a bonding agent to the walls can enhance the adhesion of the plaster. This is particularly important if the walls are highly porous or have been repaired recently. Follow the manufacturer's instructions for the bonding agent.
Cover Floors:
Protect the floor by covering it with drop cloths or plastic sheets. Plastering can be a messy process, and covering the floor prevents plaster from staining or damaging the flooring material.
Mask Off Adjacent Surfaces:
Use painter's tape and plastic sheeting to mask off adjacent surfaces that won't be plastered, such as windows, doors, and trim. This ensures a clean and defined finish without excess plaster on unintended areas.
Ensure Proper Ventilation:
Adequate ventilation is essential during plastering. Open windows and doors to allow fresh air circulation and promote the drying process. Proper ventilation also helps in dissipating any odours associated with the plastering materials.
Secure Electrical Outlets:
If there are electrical outlets on the walls, consider removing the cover plates and securing the outlets with plastic wrap or bags. This prevents plaster from entering the outlets and interfering with the electrical components.
Consult a Professional:
High quality plastering requires a professional. So if you're unsure about any aspect of the preparation process, it's advisable to consult with a professional plasterer. They can provide guidance on specific considerations for your room and ensure that the preparation and application is done correctly.
By following these steps, you'll create an ideal environment for the plastering process, leading to a more successful and visually pleasing outcome.
Plastering costs can vary, and plasterers typically offer two pricing structures: a day rate for larger jobs and a price per project. The day rate is commonly applied to extensive projects, and plasterers determine their rates based on their experience and skill level. On average, day rates for professional plasterers range between £250 and £450.
The price per project is a more flexible option that takes into account various factors:
Cost of Materials:
The type and quantity of materials required for plastering significantly influence the overall cost. High-quality materials may result in a slightly higher price but often lead to a more durable and aesthetically pleasing finish.
Duration of the Project:
The length of time it takes to complete the plastering job is a key consideration. More extensive or intricate projects may require additional time, impacting the overall cost.
Complexity of the Work:
The complexity of the plastering work is another factor influencing pricing. Intricate designs or challenging surfaces may require extra attention and skill, affecting the overall project cost.

Plastering plays a crucial role in creating a barrier against moisture and, when done correctly, can contribute to preventing mould growth. Here's how plastering helps address and mitigate mould-related issues:
Moisture Barrier:
Plaster acts as a protective barrier on walls, helping to prevent the penetration of moisture. Moisture is a key factor in mould development, and by inhibiting its entry, plastering reduces the conditions favorable to mould growth.

Use of Anti-Mould Additives:
Some modern plaster formulations include additives with anti-mould properties. These additives inhibit the growth of mould and mildew, providing an additional layer of protection.
Addressing Existing Issues:
Plastering often involves addressing any existing issues on walls, such as cracks or damage. Repairing these imperfections eliminates potential areas where moisture can accumulate, reducing the risk of mould formation.
Important Considerations:
While plastering is a valuable preventive measure, it is essential to address the root causes of moisture, such as leaks or poor ventilation, to effectively combat mould growth.
In areas with persistent moisture problems, additional measures such as waterproofing or using moisture-resistant plasterboard may be recommended.
Regular maintenance and prompt repairs to any water damage are crucial in maintaining the effectiveness of plaster in mould prevention.
Consultation and Professional Advice:
For homeowners in Worcestershire concerned about mould issues, consulting with a professional plasterer is advisable. A thorough assessment of the specific conditions of the property can help determine the most effective plastering solutions to prevent mould.
At Redline Plastering, our experienced team not only provides expert plastering services but also offers tailored advice on moisture prevention strategies. Contact us for a consultation to discuss your concerns and explore effective solutions to protect your walls from mould.
Plastering a wall can be a valuable step in managing and preventing damp issues, but it's essential to understand the limitations and considerations involved. Plastering contributes to damp prevention in the following ways:
Moisture Barrier:
Plaster acts as a barrier, helping to prevent moisture from penetrating the wall. By creating a sealed surface, it reduces the absorption of water and minimizes the potential for dampness.

Plaster provides an additional layer of protection for the wall. This coating helps safeguard the structure from water ingress, limiting the potential for damp-related problems.
However, it's important to note:
Identification of Underlying Causes:
Plastering alone may not solve damp issues caused by underlying problems such as leaks, poor ventilation, or issues with the building's damp-proof course. It's crucial to identify and address these root causes for a comprehensive solution.
Ventilation:
Adequate ventilation is essential to prevent condensation-related dampness. Plastering should be complemented by proper ventilation strategies to maintain a healthy indoor environment.
Severity of Damp Issues:
The effectiveness of plastering in stopping damp depends on the severity and type of damp. In cases of severe or specific types of damp problems, additional measures such as damp-proofing treatments may be necessary.
Professional Assessment:
For homeowners in Worcestershire dealing with damp concerns, seeking a professional assessment from experienced plasterers is advisable. A thorough evaluation of the property allows for tailored recommendations and the implementation of effective solutions.

What plaster do plasterers use?

Plasterers in the UK commonly use leading brands such as British Gypsum, Thistle, and Knauf. These brands offer a range of plaster products, including multi-finish and board finish, tailored to different applications. Professional plasterers select the type of plaster based on project requirements, ensuring a high-quality and durable finish.

Where does plaster come from?

Plaster is derived from gypsum, a naturally occurring mineral. Gypsum is extracted from mines and quarries worldwide. Once mined, it undergoes a calcination process, where it is heated to remove water content and converted into a powder. This gypsum powder is then mixed with water to create the plaster used by plasterers in construction and finishing applications.

What is lime plastering?

Lime plastering is a traditional building material that uses lime as a binder instead of cement. It consists of lime, sand, and water, creating a breathable and flexible finish. Lime plaster is valued for its ability to allow walls to "breathe," preventing moisture buildup and promoting a healthier indoor environment. It is often chosen for historic preservation projects and eco-friendly construction due to its sustainable and natural properties.

When plastering, how long do you leave between coats?

The drying time between plaster coats depends on factors like humidity, temperature, and the type of plaster used. Typically, a base coat needs to dry for 24-48 hours before applying the finish coat. However, it's essential to follow the manufacturer's guidelines and ensure the plaster is completely dry and firm before proceeding with the next coat.

Who plasters walls?

Professional plasterers specialise in plastering walls. They are skilled tradespeople with expertise in applying and finishing plaster to create smooth, even surfaces. Plasterers work in various settings, including residential, commercial, and industrial projects, providing their services for new constructions, renovations, and repairs. Hiring a qualified and experienced plasterer ensures a high-quality finish for interior and exterior walls.

Are plasterers and decorators separate trades?

Yes, plasterers and decorators are typically separate trades. Plasterers focus on preparing and finishing surfaces, applying materials like plaster to create a smooth base for paint or wallpaper. Decorators, on the other hand, specialise in the application of decorative finishes such as paint, wallpaper, and other aesthetic enhancements. While some professionals may have skills in both areas, they are distinct trades with different expertise and tasks.
