    Plastering gives a building's walls a smooth, attractive finish by applying a layer of cement, lime, or gypsum. And it's an essential part of the building since you can use it to make all sorts of textures and effects.

    Commercial wall plastering has numerous potential benefits for businesses; this article will teach you all you need to understand them.

    What Is Commercial Wall Plastering?

    Plastering a commercial wall entails applying a thin layer of plaster uniformly and smoothly across the entire surface. This plastering technique is popular among companies and commercial properties because it gives the impression of being well-maintained and attractive.

    Different Types Of Plastering Material

    The plastering material is made using a variety of recipes. The following three categories emerge from this:

    Drywall Plaster

    Most builders prefer drywall plaster due to its fire resistance and acoustic properties. Another advantage of this choice is that it can create room dividers. 

    Gypsum Plaster

    This style's characteristic feature is applying a gypsum and water mixture to walls. Gypsum plaster has a low melting point, is lightweight, and is easy to work with. It is often used on the interior of buildings, specifically on walls and ceilings. Additionally, it is an excellent insulator.

    Lime Plaster

    Construction using lime is , rare even though it is an essential component of this type.

    Cement Plaster

    This type, made by mixing cement, sand, and water, is the most common. This mixture, also known as mortar, is considered the longest-lasting option for outdoor surfaces.

    Wet Plaster

    Wet plaster, manufactured by combining lime, cement, and water, is one of the most popular plaster varieties. Most often, a trowel is used for wet application. 

    Ornamental Plaster

    As its name implies, ornamental plaster is the way to give your walls a little flair. Ornamental plaster is used for various designs, including lettering, waves, and ceiling flowers. 

    Benefits of Commercial Wall Plastering


    An extremely durable and wear-and-tear-proof surface can be achieved by plastering commercial walls. The plaster will thus be resilient enough to withstand the pressures exerted by foot and vehicle traffic in heavily populated regions. Applying heavier layers will extend the plaster's durability even further.

    Protection against Damage from Drops and Scratches

    Any business space that sees heavy foot traffic should have walls plastered with a material that can withstand dings and scratches. Plastering over flaws or cracks in the wall further strengthens it against impacts.

    Strong Bond

    The plaster will not crack or flake when applied to business walls, even in extremely vibratory or otherwise dynamic settings. The strong bonding ensures that the plaster will stay in for an extended period.

    When Should You Consider Commercial Wall Plastering?

    Avoid getting bricks and blocks wet.

    Wall plastering is a great option for homes exposed to the weather, and protecting business facilities from water intrusion is a crucial maintenance chore. Water getting into a building through cracks and holes can ruin the underlying materials and cost a pretty penny.

    Plastering establishes a barrier between the exterior and interior of a building, protecting the interior from water penetration and other types of damage.

    Prepare A Proper Base

    Filling the gaps between bricks or blocks with plaster creates a smoother surface. This increases the likelihood that the structure can sustain the weight of the stored goods and furniture.

    Modify the Concrete Casting Procedure to Take Undulations into Consideration

    If you make any lumps when pouring concrete, you can easily smooth them out by applying plaster. The plaster's ability to hide concrete flaws makes it a great choice for structures with curved ceilings or walls.

    Things That Affect Plastering Costs

    Size Of The Wall

    To give you an accurate quote, the plasterer has to know the dimensions of the wall. Bigger walls mean more plasterboard and other supplies.

    Intricacy Of The Job

    After removing the old plaster, it will take more time and resources to resurface the wall.

    Addition Of Decorative Trims And Finishes

    The plastering project's budget will grow in direct correlation to the design's intricacy and the materials required to realise it.

    FAQs About Plastering

    Common problems include cracking, delamination, uneven texture, efflorescence, and mould growth. These issues can arise due to improper application techniques, poor substrate preparation, or environmental factors.

    Achieving a smooth finish requires using the right plaster mix consistency, applying multiple thin coats, and using proper troweling techniques to achieve uniformity.

    Primers and sealers help improve adhesion, reduce porosity, and enhance the durability of the plaster surface. They also provide a stable base for paint or other finishing treatments.

    Regular maintenance includes inspecting for cracks or damage, repairing any issues promptly, cleaning surfaces as needed, and ensuring proper ventilation to prevent moisture buildup.

    Yes, commercial plastered walls can be embellished with various decorative finishes such as faux, stencilling, or textured coatings to enhance aesthetics and architectural appeal. However, ensuring compatibility with the plaster substrate and following proper application techniques is essential.

    Stages to Plaster Walls on Your Own

    If this is your first time trying plastering on your own, you undoubtedly want it to be as flawless as the work of professionals. An uneven wall that will give you grief every time you look at it is the last thing you need.

    Here, it would help if you did not take any shortcuts; plastering is an art form, and there is value in following the proper procedures to attain an impeccable outcome.

    To get good results in the end, you have to follow all six processes of plastering. Because of this, we have put together this handy guide to show you the ropes.

    The six-step plastering procedure can be started when the plaster has been mixed, the wall has been prepared, and the suction has been regulated so the plaster does not dry too quickly.

    Stage 1

    Here is where you should apply the initial coat of plaster, which should be around 2 mm thick. Plaster the trowel and start working at an angle, ensuring the front edge is not touching the wall. Smooth the plaster down to the wall in long strokes as you work. Take care not to leave any trowel traces or ridges on this initial layer; a smooth, flat coat free of bulges is paramount.

    Stage 2

    You can use a clean trowel to smooth out the first layer of plaster as it cures, being sure to push away any excess. As with most plastering techniques, the trick is to use lengthy strokes with a firm pressure, maintaining a distance of around 10-15mm from the wall with the leading edge of the trowel.

    Stage 3

    Step three is finished just before the second layer of plaster is applied. Similar to the first step, this second one involves applying half as much plaster, half as thick, and even more forceful pressure to reduce the number of holes in the plaster. It would help if you tried to remain cool because the next procedure should ideally seal any holes you may have made. At this point, you want to spend only a little bit of time filling in the gaps since that could lead to the plaster drying out.

    Stage 4

    If the plaster has lumps or holes, you can use the trowel to smooth them out. The plaster should be sticky and easily compressed into the holes, but it may create additional holes if it is too wet. To prevent dragging or scraping, maintain the trowel at a 10-15mm tilt over the wall. 

    When you press down firmly, don't worry if ridges appear; we can smooth them out afterwards. Be sure to inspect the wall for any holes as you go; if any of them aren't filling up despite your best efforts, apply additional plaster and smooth it down. You must fill most holes, but you must not rush the process; the plaster must cure.

    Stage 5

    In this area, you can use the trowel to press down on any lumps in the plaster firmly. When working with hard, resistant plaster, press the trowel at a broader angle on the wall to soften it; be careful not to scrape off any plaster.

    Stage 6

    The final and sixth stage of plastering should result in a smooth and slightly polished surface. The process starts as soon as the plaster dries and darkens in colour. Finally, press down hard with the trowel across the whole wall. Yeah, that's all!


    Commercial wall plastering is a popular technique used to give walls a smooth, attractive finish by applying a thin layer of cement, lime, or gypsum. It provides numerous benefits for businesses, including durability, protection against damage from drops and scratches, and strong bonding.

    There are three main types of plastering materials: Drywall Plaster, Gypsum Plaster, Lime Plaster, Cement Plaster, Wet Plaster, and Ornamental Plaster. Drywall plaster is preferred due to its fire resistance and acoustic properties, while gypsum plaster is lightweight and easy to work with. Lime plaster is rare but essential in construction. Cement plaster, made by mixing cement, sand, and water, is the most common and longest-lasting option for outdoor surfaces. Wet plaster, made by combining lime, cement, and water, is popular and is often applied using a trowel. Ornamental plaster adds flair to walls and is used for various designs.

    When considering commercial wall plastering, it is important to avoid getting bricks and blocks wet, address issues like diagonal-outs and plum-outs, prepare a proper base, and modify the concrete casting procedure to consider undulations. Plastering gives walls a uniform look, making them easier to decorate with paint or wallpaper, insulation, and creating decorative elements. It also provides low noise levels and hides architectural flaws.

    The cost of hiring a plasterer varies depending on the type of plastering needed. Overall, commercial wall plastering is a crucial aspect of building construction that offers numerous benefits.

    Plastering costs vary depending on the type of plaster used and the size of the wall. Standard plastering costs between $45 to $90 per square metre, while firm plaster costs between $20 to $70. Ornamental plastering is more intricate and labor-intensive, with prices ranging from $16 per square metre to $15-20 per square metre. Additional costs include wall declination, difficulty in breaking in, and costs related to creativity and complexity.

    The size of the wall, the complexity of the job, and the addition of decorative trims and finishes also affect plastering costs. To achieve a flawless plastering job, follow the six-step plastering procedure. This involves applying an initial coat of plaster, smoothing it out as it cures, applying half as much plaster, half as thick, and more forceful pressure to reduce holes. If the plaster has lumps or holes, use the trowel to smooth them out.

    Press down on lumps in the plaster firmly, especially with hard, resistant plaster, and press down hard across the whole wall. The final stage should result in a smooth and slightly polished surface, starting as soon as the plaster dries and darkens in colour.
