At Southern Liquid systems we offer specialist coatings for industrial and commercial buildings which suffer from cut edge corrosion. We have a deep knowledge of liquid waterproofing products and will be able to find the best one to maximise the lifespan of any commercial or industrial roofing which suffers from corrosion. Often we can extend the lifespan of the roof by as much as 25 years.
When metal cladding on a roof is suffering from corrosion, replacing the entire roof is nearly always avoidable. This obviously saves you the financial cost of replacing the roof, but also removes the need to halt business operations. After all most metal roof cladding systems are found on industrial and commercial buildings. Most of the time the optimal solution for corrosion on metal roof sheets is to apply a cut edge corrosion treatment. The best way to do this is to apply a coat of liquid polyurethane to encapsulate the existing cladding system.
If you have any questions about how you can treat cut edge corrosion or require a quotation for a cut edge corrosion treatment project please get in touch or call us on 0207 7818153. One of our expert surveyors will be happy to help you.
Cut edge corrosion treatment is the application of a protective coating to a metal roof sheet which has started to suffer from corrosion. This happens when the protective plastic coating which covers the metal cladding starts to erode as it is exposed to the elements. This starts on the exposed metal edges where the cladding is cut to size. This starting point where cut edge corrosion occurs is a progressive problem as over time the erosion will works its way further into the metal roof sheet. Once identified you should treat cut edge corrosion as soon as possible.
The first thing to do when treating cut edge corrosion on metal cladding is to prepare the surface for treatment. The whole of the roof cladding needs to be cleaned down using a pressure washer. This will remove any lose dirt, paint and any other form of debris.
Now all of the end joints should be sealed with a PU compatible sealant. In most cases it is wise to use a primer before applying the cut edge protection. However, this is not always the case. To be sure you should conduct a peel test. If a primer is used, you should wait until it has cured before taping all the sheet laps on the metal roof system. It is recommended to use butyl tape to do this.
Next, the cut edge protection should be applied over the surface. This can be either an acrylic-based or polyurethane-based sealant. We strongly advise choosing a polyurethane based sealant due to it's superior elasticity and long term performance.
Applying a quality protective coating, primarily extends the life expectancy of an industrial roof. However, it also enhances the aesthetic of any roof and can provide benefits to curb appeal and company branding.
Fixing cut edge corrosion is a straightforward process. After an in-depth inspection of locations to be worked on, contractors need to have a pre-start meeting to go over the scope of work, key dates which need to be met, as well as any health and safety measures necessary for completing the job. Once all details are established, it's time to get started.
The process begins by a power-washing method which clears away any loose coatings and prepares the surface for the application of our cut edge protection system. Roofers then conduct a hand grinding process to eliminate corrosion, feathering back the original coating in order to create an encapsulated tight edge that will be fortified with the cutting-edge system.
To attain a mid-sheet overlap, roofers then start by applying sealant to form the fillet of lap joint and then apply base coat. Another option here is to use butyl tape. The best coating for cut edge protection is liquid polyurethane. This can often be in a colour which will complement the client's roof sheets.
For gutter edges, a single coating should always be applied. In some situations a topcoat should be added for optimum protection. This will be completely dependant upon the system used and the manufacturers specific guidelines.
Cut edge treatment is an effective solution for those looking to repair or upgrade their roof without having to replace the entire structure. The process is relatively straightforward and offers a clear advantage over traditional silicone-based roof systems. With polyurethane solutions being better than acrylic based liquids. Keep in mind however, cut edge corrosion treatment does have its limitations, so it's important for owners to discuss all options with a contractor before beginning any project.
Though the Cut Edge Corrosion Treatment is designed to offer a high level of protection, it does have some key limitations. For starters, the treatment only works on steel reinforcements that are exposed to the elements. This means that if there are any areas on the roof where metal isn't visible – such as underneath insulation or flashing – then those areas won’t be fully protected against corrosion.
This treatment won’t protect against physical damage from heavy machinery like cranes or forklifts, and can also be easily damaged by foot traffic from people walking on it. So while cut edge corrosion treatment is an effective solution for protecting your roof’s exposed steel reinforcement, it should be used in conjunction with other safeguards to ensure your roof remains safe and secure.
It is important to note that this application process is not a substitute for regular maintenance and inspections. As with any system, the cut edge corrosion treatment requires periodic inspections in order to identify potential problems before they become more serious. Contractors will need to periodically check and re-coat the surface if necessary to keep it functioning properly over time.
Using a liquid coating to protect a roof which has started to suffer from cut edge corrosion is a great option. Not only does it provide superior protection and extends the lifespan of the roof. It is more cost-effective than removing defective metal cladding (or the whole roof). Furthermore, it is a simple process which will provide zero to minimal disruption. It can also be an aesthetically pleasing solution with a range of colours available.
That being said, there are still some drawbacks to consider when it comes to treating cut edge corrosion on your roof. The main issue is that these systems require periodic maintenance and inspections in order to remain effective over time. As such, owners will need to factor in recurring costs for inspections and repairs into their budget. Another important point to consider is how badly damage is the roof at the point the cut edge protection needs to be applied.
With cut edge protection, the ultimate objective is to protect the existing roof. Therefore, eliminating the need to tear it apart and replace it. A liquid coating will eliminate any problems caused by corrosion for at least 10 years. There are however other options similar to cut edge protection which provide additional protection against corrosion. These include the use of zinc-based primers, coatings and replacement pre-galvanised steel sheets as well as different types of sealants.
Ultimately, there is no one-size-fits all solution when it comes to preventing and treating corrosion on a roof. It’s important for owners to consider all available options before making any decisions regarding their roofs. Regardless of whether they choose cut edge protection or not. Taking the time to compare different solutions in terms of cost, durability and effectiveness, will ensure owners make the right choice for their property’s specific needs.
Cut edge corrosion is one of the most common issues industrial and commercial building owners face when it comes to metal roofs. This type of corrosion occurs primarily due to moisture, such as rain or condensation getting into the cut edge of metal cladding. Other ways corrosion can occur on an industrial building can be from improper installation techniques or using incompatible materials together such as aluminium and steel which can cause reactions which result in corrosion.
Fortunately, this problem can be prevented with the help of liquid coatings. These systems help protect against water damage and prevent the issue from occurring in the first place. As a result, owners can be secure knowing their roofs are secure and protected against potential problems down the line.
Silicone-based treatments are another popular option for preventing cut edge corrosion on metal roofs. While these systems can be effective, there are a few limitations which should be considered before making any decisions. Primarily, silicone-based treatments tend to only protect against corrosion from water and don’t offer the same level of protection as liquid polyurethane systems. Additionally, they can discolour over time and need to be reapplied regularly in order to remain effective. We have also found silicone based treatments do not hold up as well over time.
This is why liquid polyurethane is our coating of choice to treat corrosion. It provides superior protection against corrosion, due to it having increased elasticity. It is also more durable than both silicon and acrylic based treatments. Furthermore, they are easy to install and come in a variety of colors so owners can customise their roofs’ appearance as needed.
In conclusion, liquid coatings are an excellent way to protect and treat metal roofs suffering from corrosion. Not only does it offer superior protection, but it’s also cost-effective and easy to install. The only downside is it requires regular maintenance and inspections in order to remain effective over time. There are also some situations where a roof is too badly corroded to be treated.
It’s important for owners to consider all available options. With the right precautions in place, they can ensure that their structures stay safe and secure for years to come.
