Protective Coating
Providing Enhanced Protection to ensure Lasting, Outstanding Performance

Intumescent coatings

Fire protective coatings or intumescent coatings are applied to load-bearing surfaces as a highly effective prevention method against the structural collapse of buildings. Once applied to the surface, the coating or paint acts to delay its deterioration when exposed to intense heat. Temperatures can reach between 200°C to 600°C before the paint’s molecular structure swells, in a controlled manner, to many times its original thickness. This produces a large number of minute bubbles that harden once cooled; creating a protective, carbonaceous char.

There has been a recent surge in demand for intumescent coatings within the architectural design industry due to its consistency. Usually used on steel structures, it can also be applied to timber and plaster. This protective coating performs best with metal structures but can offer protection against fire exposure for wood and plaster in terms of time. For example, a layer of intumescent paint applied to timber can increase its resistance against intense heat to 30, or, in some cases, 60 minutes.

AS utilises industry leader CLM Fireproofing’s specialism and experience to ensure the best results are achieved for all of our clients’ fireproofing needs.

Hot zinc spraying

This is a process whereby zinc wire is passed through a compressed air gun, and heated into liquid form, which is then sprayed onto the substrate creating an even, protective layer. AS uses the arc spraying method instead of flame spraying to ensure a more safe and environmentally friendly approach. Arc spraying forces two electronically charged wires through the gun creating an electric arc that melts the metal, to then be propelled at the surface by the compressed air. From a technical standpoint, arc spraying can reach a higher bond strength which some substrates will require in harsher conditions.

Flame spraying uses the heat produced from the combustion of a mixture of gasses to melt the wire; personal preference would therefore sway a contractor’s choice between the two.

Benefits of a surface protective coating

Protective coating offers a long list of benefits across a variety of requirements, fields, and industries. Discover how it could assist you; no matter the sector you and the surface are in.

Durable & Resistant
Protective coatings will offer an immense amount of resistance to a wide range of pollutants. Intumescent paint and coatings increase substrates' heat resistance allowing for a longer evacuation time in the event of a building fire. Zinc spraying applications enhance the substrate’s durability against harsh conditions such as salt spray and chemical exposure - commonly used in the shipping and marine industry where superstructures and vessels are vulnerable to corrosion.
Environmentally Sustainable
Meeting sustainability standards has become an increasingly important factor across all sectors, and the coatings industry is no different. Protective coating's longevity and resistance actively contribute to a reduction in paint coatings required (minimising the release of VOCs), whilst working to extend the lifespan of equipment and building materials. As a result, this method is highly environmentally beneficial.
Widely Recognised
Intumescent paints aid in structures meeting regulatory fire requirements along with the use of other mediums. If steel beams are exposed, it is an industry-standard for them to be coated in a fireproofing paint which performs as an expanding barrier to ensure fire and extreme heat does not impede the structural integrity of buildings.
Aesthetically Pleasing
Not only do protective coatings provide long-lasting durability against harmful conditions - they also give surfaces a new lease of life. With a wide range of available textures and colours, protective coatings don’t need to be only functional but can be the perfect finish to your machines, equipment and buildings.

Protective Coating FAQs

[wp-faq-schema accordion=1]

How does Protective Coating work?

With the main purpose to preserve and decorate the surface, it is applied to, protective coatings offer a durable and hardy layer to prolong its life and finish. Prior to coatings, preparation takes place to enhance the surface’s texture, usually in the form of blast cleaning. When exposed to contaminants the hardened surface will be able to withstand even the harshest conditions.

How does intumescent coatings work?

Intumescent coatings will provide an expanding, fireproof layer which is designed to prolong the resistance a surface has against fire and extreme heat. The most effective and efficient way to apply this protective coating is by spraying; guaranteeing every inch of the surface is coated sufficiently so it can work as best as possible. Once applied to the surface and exposed to heat, the coating starts to expand and char instead of the surface itself to allow authorities to act and stop the fire spread.

How does hot zinc spray work?

Hot zinc spray gives an extra, hardened coat to repel factors such as salt spray, chemical exposure, and corrosion. Substrates are all prepared, usually with abrasive blasting, which creates a rough outer layer for the zinc to adhere to and bond with. When the melted wire is passed through the gun and sprayed, the metal impacts and fixes onto the surface to provide protection from harsh conditions.

We don’t just offer Protective Coatings

We accommodate an eclectic range of blasting and coating projects throughout East Anglia, the South East and the East Midlands. Ensuring the best results are always achieved, we provide a bespoke approach, tailored to the surface’s needs using our wide range of services.

Powder Coating

A more environmentally friendly approach to product finishing, our powder coating services exceed many national environmental protection standards – minimising wastage and the presence of Volatile Organic Compounds whilst being tough and durable. This modern approach to coating can be used in place of liquid painting and curing, reducing the negative environmental impact of VOCs, whilst producing the same brilliant results.

Blast Cleaning

Many of our blasting services, such as those for brick or stonework, can be performed at the site of the surface for convenience, whilst many smaller components, such as oak beams and motorbikes can be blasted at our dedicated in-house facility. We use a variety of abrasives to achieve the specific finish required, including Australian garnet, copper slag, aluminium oxide, stone grit, recycled glass and glass bead.
