What Is Intumescent Coating?

Intumescent coating refers to a specialised paint-like substance that we apply to structures for enhanced fire protection. These coatings expand when exposed to heat, forming an insulating char layer.

This layer helps to prolong the structural integrity of steel and wood elements during a fire. Intumescent coatings contain binders, catalysts, and carbon agents that essentially delay the rise in temperature of the substrate to which they are applied.

This technology is crucial in meeting fire safety standards like BS 476 and EN 13501, ensuring buildings maintain stability for a specified duration under fire. The coatings can be applied using spray equipment, brushes, or rollers, depending on the project requirements.

Our typical projects involve commercial buildings, warehouses, and industrial facilities, where maintaining structural integrity during a fire is vital. Clients benefit from our expertise in applying both thin film and thick film intumescent coatings, suitable for different exposure conditions.

Our service helps in safeguarding assets and ensuring compliance with safety regulations.

What Types of Intumescent Coating Are Available?

We provide several types of intumescent coatings to meet different fire protection needs:

Water-Based Intumescent Coatings: Ideal for indoor applications, these coatings offer excellent fire resistance and are environmentally friendly. They are particularly suitable for residential and commercial buildings due to their low VOC content.
Solvent-Based Intumescent Coatings: Suitable for harsh environments, these provide durability and resistance to humidity. They are often used in offshore and marine structures, where high endurance is required against moisture and salt spray.
Epoxy-Based Intumescent Coatings: Used for industrial purposes, they deliver superior adhesion and chemical resistance. Commonly applied in petrochemical facilities, they can withstand extreme temperatures and chemical exposure.
Acrylic Intumescent Coatings: These offer a smooth finish for architectural projects and are ideal for ensuring aesthetic continuity while providing fire protection. Permanent structures often benefit from their UV resistance and colour retention.

Each type is designed to meet specific requirements, and we can help determine the right choice for your project.

What Surfaces Does Intumescent Coating Work On?

SB3 Coatings applies intumescent coatings to a variety of surfaces to ensure optimal fire protection. These include structural steel, wooden beams, walls, and ceilings.

For structural steel, we measure the specific thickness of the coating required based on the fire resistance period needed, typically 30 to 120 minutes. On wooden beams, our coatings retain the natural aesthetics while enhancing fire performance.

We also work with plasterboard surfaces, where we prepare them to meet specific fire rating requirements in compliance with BS EN 13381 standards. Our coatings are not suitable for use on plastic surfaces or other non-structural materials that do not require fireproofing.

We use airless spray equipment for clean and efficient application, especially on extensive surface areas. Speak with us today to determine the best solution for your project.

When Is Intumescent Coating Needed?

Intumescent coating is essential when building regulations demand enhanced fire safety. It expands when exposed to high temperatures, forming an insulating layer that protects steel beams and columns from the intense heat of a fire, crucial for maintaining structural integrity.

Buildings susceptible to fire risks, such as commercial structures, residential apartments, and public facilities, benefit significantly.

Industries dealing with flammable materials, like chemical plants and refineries, often require intumescent coatings. Additionally, areas with specific fire rating requirements, such as airports and hospitals, regularly incorporate it to meet safety standards.

New builds, renovations, or properties near fire-prone areas should consider intumescent coatings as a preventive measure. For a tailored assessment, contact SB3 Coatings.

How Does Intumescent Coating Work?

At SB3 Coatings, we follow a precise application process to ensure optimal fire resistance and structural safety:

Surface Preparation: Cleaning the substrate to remove dirt, grease, or rust, then applying an anti-corrosive primer to enhance adhesion. We use abrasive blasting for steel surfaces to achieve the necessary cleanliness and surface profile as per ISO 8501-1 standards.
Application of Base Coat: Applying the first layer, which ensures a smooth and uniform coverage, facilitating better adherence of the subsequent intumescent layers. The base coat also acts as a sealant, protecting the substrate from moisture.
Intumescent Coating: We apply the main intumescent layer using either spray equipment for large areas or brushes for small, detailed sections. The coating expands when exposed to heat, forming an insulating char layer to protect structures during a fire. Thickness is determined by the fire rating required, typically measured in microns.
Final Inspection: Our team conducts a thorough inspection to verify the coating's thickness and continuity, ensuring compliance with BS 476 standards and fulfilling client specifications. Additional checks involve verifying the curing duration and environmental conditions for optimum performance.

With our approach, we ensure the safe and effective implementation of intumescent coatings tailored to different building types and client needs.

How Long Does Intumescent Coating Take?

The application of intumescent coating typically takes around two to three days for an average-sized project. This involves surface preparation, including cleaning and priming, to ensure the coating adheres properly.

We use airless sprayers or manual application methods depending on the structure size and complexity. Drying time depends on the specific product used and environmental conditions but usually takes 24 to 48 hours.

Humidity and temperature can affect drying, with controlled indoor settings often facilitating faster curing than outdoor environments.

Intumescent coatings are usually applied in several layers, each needing adequate time to dry for optimal fire protection performance. The coatings expand when exposed to high heat, offering fire resistance of up to 120 minutes, crucial for safety compliance in commercial and residential properties.
