Comparison between spray plaster and traditional plaster

When it comes to plastering walls, homeowners and contractors have traditionally relied on manual application. This time-honoured technique involves mixing the plaster powder with water, applying it to the wall using a hawk and trowel, and then meticulously smoothing the surface to achieve a smooth, flawless finish. While traditional plaster has been the go-to option for so many years, introducing spray plaster in the UK will revolutionise how we approach this essential construction task.
Spray plaster, as the name suggests, utilises an airless sprayer and spray gun to apply a layer of plaster onto the surface. This more modern approach offers several distinct advantages over the traditional method. Unlike the laborious process of manually spreading and smoothing plaster with a hawk and trowel, spray plaster can be applied quickly and efficiently, saving valuable time and effort. The use of skimming blades replaces the trowel, covering a larger area and making the process even more time-efficient.
Spray plaster is a product that is easy to sand, enabling the plaster to be applied in hard-to-reach areas and around intricate architectural features with ease. This makes spray plaster an ideal choice for complex projects or renovations where traditional plaster may prove challenging to work with. Furthermore, the reduced physical exertion required for spray plaster application can be particularly beneficial for larger-scale projects or for those who may have physical limitations, providing a more comfortable working experience.

Benefits of spray plaster

The advantages of spray plaster over traditional plaster extend far beyond the application process. One of the most significant benefits is the considerable time savings it offers. Spray plaster and the spray application method is significantly faster than the manual process, with 1 -3 days drying time depending on the weather, allowing contractors and homeowners to complete their projects in a much shorter timeframe compared to the time it takes for Multi-Finish to dry. This increased efficiency can be particularly valuable when time is of the essence, such as commercial renovations or tight project deadlines.

Not only does spray plaster save time, but it also delivers a superior level 5 finish. The spray gun’s even distribution of plaster results in a smooth, consistent surface that requires minimal sanding or additional finishing work. This high-quality finish is a testament to the professional look that spray plaster can achieve, surpassing the traditional plaster application.

Another notable benefit of spray plaster is the reduced mess and waste associated with the process. Traditional plaster application can be a messy and labour-intensive endeavour, often discarding excess material or requiring extensive cleanup. Also, you need access to water when using traditional multi-finish, whereas spray plaster is ready-mixed, making life a lot easier.

In contrast, spray plaster minimises the amount of overspray and waste, as the airless sprayer allows for precise control and targeted application. Spray plaster not only saves time and effort during the project but also reduces the environmental impact and disposal costs associated with traditional plaster waste.

Faster application and drying time

One of the most significant advantages of spray plaster is the speed at which it can be applied. The spray application method is significantly faster than the manual process, allowing contractors and homeowners to complete their projects in a shorter timeframe. But the biggest game changer is the time spray plaster takes to dry! We have done new builds and extensions ourselves using spray plaster but have also worked over spray plaster as decorators, and we know the time saved on drying times alone is a massive benefit.

Depending on the substrate the plaster is going over, you need to apply two coats of spray plaster. Generally speaking, you would be looking at two coats over plasterboard, for example. In the warmer months, you can apply both coats on the same day, leaving them to dry for 24-48 hours before painting. Just imagine the time you would have to wait for traditional plaster.

Improved coverage and finish

One of the standout features of spray plaster is its ability to provide a superior, consistent level 5 finish compared to traditional plaster application. Unlike manual plaster application, where unevenness and inconsistencies can be challenging to avoid, the spray technique ensures a flawless, seamless finish. The sprayer can reach into corners, around intricate architectural features, and other hard-to-access areas, allowing for coverage without uneven patches and is really easy to sand.
Moreover, the spray plaster’s ability to create a smooth, consistent surface can also enhance the space’s overall aesthetic. The absence of visible seams in larger areas where traditional multi-finish would have dried out doesn’t happen with spray plaster. You can keep a wet edge for longer, and it blends perfectly. Another win for spray plaster is that it is white, so you don’t get that damp, dark feel in the room once it’s been completed. Instead, you get a clean, bright space to work with.

Reduced mess and waste

One of the most significant advantages of spray plaster is the reduced mess and waste associated with the application process. The application of traditional plaster can be messy and labour-intensive, often resulting in excess material being discarded or requiring extensive cleanup. Spray plaster, in comparison, is efficient, clean and tidy. As the plaster does not need to be mixed with water, you can use it as you need it, so there is minimal wastage, and unused product in the machine can be transferred back into a tub and used later. The messiest part is setting up and cleaning down the sprayer, but that’s not only fun but easy in comparison.


This reduction in mess and waste saves time and effort during the project. It has a positive impact on the environment. By minimising the amount of plaster material that ends up in landfills or requires particular disposal, spray plaster is more eco-friendly than traditional plaster. This can particularly appeal to homeowners and contractors who are conscious of their environmental footprint and seek to adopt more sustainable construction practices.

Enhanced durability and resistance

In addition to the application and aesthetic benefits, spray plaster offers enhanced durability and resistance compared to traditional plaster. The spray application process results in a more consistent and uniform plaster layer, which can contribute to its long-term performance and resilience. Although spray plaster may seem less durable than traditional plaster, the spray plaster hardens and becomes very durable once painted. Moreover, if the plaster becomes damaged, then it can easily be repaired and painted, making spray plaster the best and most up-to-date solution.

Cost-effectiveness of spray plaster

While the initial investment in spray plaster equipment may be higher than the tools required for traditional plaster application, the long-term cost-effectiveness of this approach should be considered. The increased efficiency, reduced waste, and enhanced durability of spray plaster can ultimately result in significant cost savings over a project’s lifetime.


The faster application and drying times associated with spray plaster can lead to reduced labour costs, as fewer people are required to complete the job in a shorter timeframe. Additionally, the decreased amount of waste and cleanup required can further contribute to cost savings, as less material needs to be purchased, transported, and disposed of.


Moreover, the improved finish and enhanced durability of spray plaster can translate to reduced maintenance and repair costs down the line. The seamless, crack-resistant surface created by the spray application process can help extend the plaster’s lifespan, potentially reducing the need for costly touch-ups or full-scale re plastering in the future. This long-term durability can be particularly beneficial for commercial or institutional buildings, where the cost savings can be substantial.
