At Paint While U Wait, we are proud to offer intumescent painting in Brynmawr as part of our comprehensive range of spray painting services.
This modern innovation is - literally - a lifesaver, and these specialist paints are now required by law in many industrial, commercial and public buildings in Brynmawr, particularly when structural steel beams are used.
To ensure that these coatings work efficiently and correctly, it is essential that they are installed by a professional painting company like Paint While U Wait.
Intumescent paints are specially formulated coatings that can withstand high temperatures to provide a passive fire protection system for buildings of all types in Brynmawr, but mainly in commercial and industrial buildings. Basically, they are used to protect structural steel internally and externally, although they can be used on other materials (more on this later).
When exposed to heat, intumescent coatings undergo a chemical reaction that causes them to expand, forming a thick, insulting char layer. This layer is designed to protect the structural integrity of buildings by slowing down the time it takes for fire to reach steel beams or other load-bearing elements.
The aim of these coatings is to allow more time for people to be evacuated and for the fire to be extinguished before any permanent or major damage is done to the structure.
At Paint While U Wait, we bring years of experience and a proven track record of excellence to every project. Whether it’s your home, business, or any property in need of revitalization, we deliver results that exceed expectations.






When exposed to extreme heat, a steel structure can be compromised. At temperatures exceeding 550º or above, the load-bearing capacity becomes significantly weaker by around 50%, greatly increasing the risk of collapse.
The chances of a fire breaking out are higher in industrial and commercial buildings, which is why fire safety regulations now stipulate that all buildings using structural steelwork must be coated with intumescent paint.
No, under no circumstances should you try to apply an intumescent paint coating yourself. The application process requires specialist training and is covered by strict regulations, including:
Paint While U Wait's professional intumescent painters in Brynmawr ensure that all rules, regulations and guidelines are followed to the letter. Because of this, you can be confident that your structural fire protection system will work exactly as it should, if or when it is needed.


There are several different types of intumescent coatings, based on either the composition, material, or thickness of application.
Paint While U Wait will advise you on this point to make sure you get the necessary fire protection required by law, and that the fire retardant paint suits the specific needs of your building.
The following guide will explain the main differences to be aware of:
Formulated with organic solvents, these coatings are quick-drying, making them more suitable for situations where a rapid application and curing time is required.
They offer excellent durability and moisture resistance, making them particularly well-suited for environments where exposure to dampness or humidity is a concern. Due to this, they are often used in industrial facilities or outdoor settings where environmental conditions are challenging.
Their performance remains robust, even in the worst circumstances, ensuring long-term fire protection.
This is a low-VOC eco-friendly choice, as the main solvent is water. This makes them ideal for the modern business trying to balance fire safety regulations with sustainability goals.
These coatings require careful application under controlled conditions to provide optimal adhesion and performance. High humidity or freezing temperatures can compromise the coating's effectiveness during the application process.
Because of this, intumescent painting contractors often recommend that these coatings are used on internal features.
Epoxy resins form the binding agent in these coatings, offering exceptional durability and resistance to harsh conditions, including exposure to chemicals, abrasion, and moisture. These characteristics make them particularly suitable for extreme environments such as offshore and marine applications, including oil rigs and ship structures.
However, they generally cure much more slowly than other types, requiring more time until they reach full strength.
Even so, they are extremely robust in severe conditions common in heavy-industry, making them a preferred choice for long-term reliability.
These are so-called because the paint is applied in layers less than 1mm thick (before expansion). They are lightweight and more aesthetically pleasing, as they can be covered with other paints if necessary to provide a less 'industrial' or textured appearance.
Thin film coatings are usually reserved for commercial or residential buildings, providing fire protection for up to 120 minutes.
Thick film coatings are applied in layers from 5mm up to several centimetres in thickness, providing protection for as long as four hours. These are ideal for heavy-duty environments, such as industrial plants, tunnels, and offshore platforms.
The 'char' is the protective layer formed by the chemical reaction in the paint, and this is described as either soft or hard. Once all the vapour is released from the paint, the remaining char slows the transfer of heat to the substrate.
Here's a brief explanation of the difference between the two:
At ambient temperatures, the paint maintains its normal, stable appearance and composition. It's only when exposed to high temperatures that the chemical reaction takes place.


While the fire safety rules specify that structural elements must be coated, these lifesaving paints can be applied to other materials to provide the same level of fire resistance.
Here are some of the materials that we can apply intumescent coatings to if required:
As mentioned above, any steel structure loses half of its load-bearing capacity at 550º or above, and this only worsens as the temperature increases.
Intumescent products slow down the heat transfer to the material without changing the mechanical properties of the steel framework. They also allow more time for emergency services to attend and deal with the situation before it becomes too serious.
Wood is naturally combustible, so it needs an extra helping hand. Paint While U Wait's fire protection painting contractors will treat your wooden surfaces and structural components to slow down combustion and heat penetration.
One of the benefits of intumescent paint for wooden features is that it preserves the wood's natural appearance. This makes it ideal for applications where aesthetics and fire safety are equally important, such as in architectural or decorative timber structures.
While concrete is naturally fire resistant, high temperatures can cause it to spall. This is when cracks form and pieces break off, exposing the reinforcement bars beneath, which can potentially weaken the structure.
Intumescent coatings for concrete enhance its fire resistance by forming a protective barrier during high temperatures, reducing the risk of spalling and helping to maintain the structure's integrity. This type of intumescent fireproofing is especially valuable in infrastructure like tunnels and high-rise buildings, where prolonged exposure to fire can be catastrophic.
Some intumescent coatings are designed for plastic pipe protection or to safeguard other types of lightweight and versatile materials, including composites.
These are increasingly used in the manufacturing and industrial sectors due to their high strength-to-weight ratio and flexibility. However, they are also highly susceptible to rapid burning and deformation under fire conditions.
Paint While U Wait intumescent fire protection services increase the fire resistance of these materials by applying a suitable coating. The insulating char layer forms a fire barrier that slows ignition and flame spread, helping you to meet stringent safety laws while retaining the functionality of the materials.
Although commonly used on steel beams, these versatile coatings can be applied to many other features, including:
These few examples illustrate the usefulness of intumescent coatings, but there are many others we could mention. Please contact us to discover more!


Intumescent painting services are regarded as a cost-effective solution in the long term. While the initial costs are generally higher than other forms of fire protection, such as extra fire doors and partitions, they provide a far higher level of protection, potentially saving you a vast amount of money.
On average, intumescent painting contractors charge between £12 and £25 per square metre for commercial buildings and £18 to £40 for industrial settings, depending on the size and scale of the project as well as the type of paint used and the thickness required.
As for labour costs, a typical intumescent painting project may be between £20 to £50 per hour depending on the complexity of the work and location.
Additionally, we need to factor in the fire resistance duration (e.g. 30, 60, 90 or 120 minutes) as well as the substrate type and environmental conditions.

In the event of a fire, intumescent coatings expand by up to fifty times their original thickness! It's this insulating layer that prevents fire damage and reduces the chances of structural collapse.
The thicker the initial coat, the more protection it provides in the event of a fire.
Heat damage and smoke damage are two of the worst effects of any fire, aside from the risk to life, and intumescent paint is brilliantly engineered to limit these, potentially saving you a vast amount of money in repairs and renovation.


Fire protection coating isn't just about protecting buildings in Brynmawr, it's also about keeping humans safe. In fact, this is their main purpose - saving the physical structure is a secondary concern, albeit an important one.

Intumescent painting is a fireproofing technique that uses special coatings to protect structures from fire damage. The paint expands when exposed to heat, forming a protective layer that insulates the material beneath.
Intumescent paint works by expanding when heated, forming a thick, insulating layer that prevents fire from reaching the surface beneath. This helps to delay the spread of fire and protect the integrity of the structure.
Using intumescent paint provides an effective and cost-efficient solution for enhancing fire safety. It forms a protective layer on surfaces, slowing down the spread of fire and potentially saving lives and property.
Intumescent paint can be applied to various surfaces, including steel, timber, concrete, and plasterboard. It is commonly used in buildings, warehouses, and industrial sites for fire protection.
The longevity of intumescent paint depends on factors like application thickness, surface condition, and exposure to environmental elements. Typically, it can last up to 10-15 years if maintained properly.
The cost of intumescent painting varies based on the size of the area to be covered, the type of surface, and the complexity of the job. On average, prices range from £10 to £30 per square metre.
