What are the benefits of spraying cladding?

While some may think of cladding coating as simply a coat of paint to improve the look of a building, it is so much more than that. The benefits of a professional cladding coating on steel, cement, and timber cladding cannot be overstated, especially its protective qualities. Spraying external and internal cladding with top-of-the-line products designed to stand the test of time is essential to keeping your cladding performing at its best.

What will a professional application of cladding coating protect my cladding from?

In this post, we’ll cover what cladding spraying can protect your cladding material from, and why it’s a step that cannot be missed when maintaining and extending the longevity of your property. Let’s discuss the main offenders that can cause damage to your uncoated or old cladding.

Weather

There is no escaping the weather, no matter where you are; if your cladding is outside, it’s going to be exposed to the elements. Rain, hail, snow, and even sun can do damage to cladding materials, from steel to cement, so it’s essential that it is protected against what nature throws at it.

Each area of the world has its own climate that cladding must survive, but here in the UK, with our constant back and forth between bright sun and sheets of rain, cladding faces a real mixed challenge. We use products that are designed to keep their integrity in all weather types, from preventing rain damage to maintaining the cladding’s colour.

UV radiation

The sun can do a lot more damage to cladding and old coatings than you may realise. Those strong UV rays have the power to bleach and fade colour, while the direct heat can curl and peel coatings that are cheap or tired. Once that old coating comes off, the naked material beneath is entirely exposed to the elements and the damage they can cause. What’s worse is that different exterior walls of your building will suffer more than others depending on the direction they face, leaving an uneven and off-putting property facade.

A professional spray coating using industry-leading products acts like SPF for your cladding, protecting it against the sun and its UV radiation to keep it looking fresh.

Corrosion

Corrosion can be the start of your cladding’s failure, especially when the material is metal. Corrosion, often caused by environmental factors, typically appears as rust or the delamination of an old, worn coating. Corrosion is especially common on the cut edges of metal cladding sheets, which are usually left unprotected and unsealed by the manufacturer, leaving them exposed to the elements.

A professional coating of high-performance cladding spray will not only protect the cladding from corrosion, but also treat it. This seal against moisture helps improve the lifespan and durability of your cladding, reducing the likelihood of damage.

Water damage

Water damage can be a real threat to your cladding and property, no matter the source. Whether it’s from rainfall, dripping from overhanging trees, or the air around your site is full of moisture, if your cladding gets wet, it can get damp and deteriorate. When water penetrates the exterior layer of your property, you could face mould, rot, discolouration, leaks, and in some cases, maybe even damage to the building’s structure.

Waterproof cladding coatings prevent water from soaking through and causing these types of damage, improving the longevity of your cladding and helping to prevent future costly cladding replacements or structural repairs.

Dirt and pollutants

Dirt, pollutants, pollen, and grit can stick and collect on uncoated cladding, leading to several problems down the line.

  • Aesthetic depreciation: Dirty walls and surfaces, both internal and external, give properties a neglected appearance that can have a detrimental effect on your business’s reputation.
  • Staining: Dirt and pollutants can discolour your cladding material, especially if it’s made of cement or wood, which can be difficult or impossible to remove.
  • Degradation: Accumulated dirt, dust, and other airborne debris have the power to damage some materials, especially the more porous ones. This can affect the material’s integrity and shorten its lifespan.

With a professional application of a cladding coating, you create a barrier between the cladding and the problem. This dirt-repellant coating is far easier to clean than the cladding itself, meaning grime can simply be sprayed off for easier maintenance.

Aesthetic damage

With a tough and durable coating, your cladding has an extra line of defence against minor physical damage. The coating will catch those scratches and small dings before they hit the cladding material, protecting it against these slight aesthetic impairments. It might not seem like much, but touching up the cladding coating is a lot easier than dealing with scrapes across the raw material that could eventually lead to failure.
