Victoria Bramley, Product Manager at Okarno, looks at why the popularity of roll-applied coverings continues to grow
One of the main benefits of roller-applied coverings is their ease of use and time-saving efficiency. Unlike trowel coverings, which need more application effort and can be troublesome to attain a smooth finish, a roller-applied product can be easier to apply quickly and uniformly.
This speed is particularly beneficial for site teams working to tight deadlines, allowing them to complete projects faster and avoid having to wait for specialist trades.
While roller-applied coverings have significant benefits, they shouldn’t be viewed as a one-size-fits-all solution for every plastering need.
In some situations, as we explore below, there are still scenarios where professional plastering skills are irreplaceable, particularly for major repairs or heritage restoration projects. The key lies in understanding the appropriate applications for each method and choosing the right approach for each specific project.
Here we look at some common questions that our customers ask about roller-applied coverings:
What are roller-applied coverings?
They comprise a unique formula of ready-mixed materials that are supplied in tubs and used for smoothing walls and ceilings. Whether dealing with nail pops, cracks or other minor surface flaws, they can help restore a smooth, even finish. For larger gaps and cracks, roller-applied coverings can be used with scrim or joint tape for a stronger, longer-lasting job.
Are they easy to apply?
Yes, roller-applied coverings are designed for quick and easy application. It’s possible to roll our Dalapro Roll Nova directly from the tub, making it accessible for users with minimal experience in plastering. The fact that it’s grey in colour, makes it easy to see where it has been applied, ensuring complete coverage. It is simply rolled straight onto the wall, smoothed with a skimming blade and left to dry.
What tools do I need?
You will need a medium to high-pile roller (preferably 9 inches for best results) and roller pole. Once the covering has been applied to the wall, you’ll need a skimming blade to smooth it. This application method tends to be cleaner, with reduced spillage and less need for extensive preparation.
What kind of substrates can I cover?
The creamy texture of our roller-applied covering ensures smooth application and excellent adhesion to various surfaces, including plasterboard, concrete and even textured finishes, making it suitable for both minor repairs and larger wall coverings.
What is the drying time?
With an average drying time of around eight hours, roller-applied coverings allow you to apply the product in the late afternoon, and it will dry the following day, depending on environmental conditions such as humidity and temperature. Good ventilation can help speed up the drying process.
How do I prepare the surface before application?
Proper surface preparation is still crucial to ensure optimal adhesion and finish. It’s essential to sand the surface and fill deep cracks before application. Ensure that the surface is clean, dry and free from loose debris. Taping around sockets and fixtures can help achieve a cleaner application and prevent mess.
Are roller-applied coverings a replacement for all traditional plastering techniques?
While effective for surface repairs, roller-applied coverings cannot entirely replace traditional plastering techniques, especially for more complex jobs.
Can I use it on textured surfaces?
Yes, roller-applied coverings like Dalapro Roll Nova can be applied over textured surfaces on walls and ceilings. However, it is recommended to sand down the most pronounced textures to ensure a smoother finish. Multiple thin coats may be necessary to achieve the desired result without adding excessive weight or moisture that could compromise the underlying surface.
Can I paint over roller-applied coverings?
Yes, once the covering has dried and been sanded to a smooth finish, it is ready for painting. Ensure that the surface is dust-free before applying.
Where can I buy roller-applied coverings?
Our Dalapro Roll Nova 12-litre tubs, which will cover 12m2 at 1mm thick, can be purchased from merchants and stockists nationally.
Last word
Undoubtedly, roller-applied coverings offer numerous benefits, including ease of use and time efficiency. However, they do not substitute traditional plastering techniques in all scenarios. Understanding the strengths and limitations of each method is crucial for achieving the best results on site. By combining the advantages of both approaches, contractors can create high-quality finishes that stand the test of time and provide your customers with value for money.
