Fire-resistant coatings & intumescent spray painting for commercial, industrial, and residential buildings. Certified fireproofing solutions that slow fire spread and meet UK regulations.
Fire-Resistant Coating Services We Offer
Intumescent Coatings for Structural Steel
Intumescent fireproof coatings expand when exposed to heat, creating an insulating barrier that protects steelwork for 30, 60, or 120 minutes, preventing structural collapse. We apply thin-film intumescent coatings to beams, columns, and load-bearing structures, ensuring full compliance with BS 476 and EN 13381 fire protection standards.
Fire-Retardant Paint for Walls & Ceilings
Our fire-retardant coatings are designed for plasterboard, concrete, timber, and existing painted surfaces, slowing down the combustion process and limiting fire spread. This is an ideal solution for commercial buildings, offices, and public spaces looking to improve their fire resistance.
Fireproof Coatings for Wood & Timber
We offer fire-resistant clear and coloured coatings for doors, panels, and wood surfaces, ensuring compliance with Class 0 and Class 1 fire safety ratings. Our coatings maintain the natural look of wood while providing essential fire protection.
Cementitious Fireproofing for Industrial Sites
For large-scale warehouses, factories, and industrial units, we apply cementitious fireproof coatings, offering high-performance passive fire protection for steel and concrete structures.
Thermal Barrier Coatings for High-Heat Resistance
Our thermal barrier coatings (TBCs) provide insulation and fire resistance for high-temperature environments, including power plants, storage facilities, and aerospace industries.
Our Process – How We Apply Fire-Resistant Coatings
1. Surface Preparation
- Cleaning, degreasing, and priming surfaces to ensure maximum adhesion.
- Masking and protecting surrounding areas from overspray.
2. Application of Fire-Resistant Coating
- Spray application of intumescent or fire-retardant coatings using airless spray technology.
- Multiple layers applied to meet required fire resistance ratings.
3. Quality Control & Compliance Checks
- Thickness testing to ensure coatings meet fire safety certification standards.
- Final inspection and certification provided upon completion.
What Are Fire-Resistant Coatings and Why Do You Need Them?
Fire-resistant coatings provide critical fire protection for buildings, structural steel, wood, and other materials, helping to slow fire spread and reduce heat transfer. These coatings are essential for commercial buildings, warehouses, offices, and residential properties to ensure compliance with UK fire safety laws and insurance requirements. Our intumescent coatings expand when exposed to heat, creating an insulating layer that prevents premature structural failure. Investing in fire-resistant coatings not only enhances safety and compliance but also offers long-term protection against extreme temperatures.
How Intumescent Coatings Provide Fire Protection for Steel & Structures
Structural steel can lose its load-bearing capacity in just minutes during a fire. Intumescent coatings are designed to expand up to 50 times their original thickness, forming a protective char layer that insulates the steel and prevents it from reaching critical temperatures. This extends fire resistance ratings to 30, 60, 90, or 120 minutes, giving emergency services crucial time to respond. Our spray-applied intumescent coatings meet BS 476 and EN 13381 standards, ensuring full regulatory compliance for commercial and industrial buildings.
Fire-Retardant Paint for Walls, Ceilings & Wood Surfaces
Fire-retardant coatings are essential for walls, ceilings, doors, and timber structures, reducing the flammability of surfaces and limiting the spread of fire. Whether you need fireproofing for office spaces, hotels, or public buildings, our fire-retardant paints provide Class 0 and Class 1 fire ratings, ensuring compliance with building regulations. Available in clear or coloured finishes, these coatings are ideal for protecting both modern and heritage buildingswhile maintaining aesthetic appeal.
Cementitious & Thermal Barrier Coatings for Industrial & High-Heat Environments
For warehouses, manufacturing plants, and industrial facilities, cementitious fireproofing provides high-performance passive fire protection for steel and concrete structures. These thick, spray-applied coatings withstand extreme temperatures, preventing heat transfer and delaying structural collapse. Our thermal barrier coatings offer additional high-heat insulation, making them perfect for storage facilities, power plants, and aerospace applications.

Have questions in mind?
Read our FAQs below.
Fire-retardant paint slows down combustion and prevents fire from spreading, while intumescent coatings expand when exposed to heat, forming a thick, insulating barrier that protects structural steel and other materials from fire damage.
Fire-resistant coatings provide long-term protection, but lifespan varies based on environmental conditions and coating type. Intumescent coatings for steel can last up to 30 years, while fire-retardant paints may need reapplication after 5-10 years, depending on wear and exposure.
Yes, UK building regulations require fire protection for commercial, industrial, and residential buildings. Structural steel must meet fire resistance ratings of 30-120 minutes, while walls, ceilings, and doors must comply with Class 0 and Class 1 fire safety standards.
Absolutely. Our fireproof coatings can be applied to new and existing buildings, including steel structures, wooden surfaces, walls, ceilings, and industrial cladding. We assess each surface to ensure optimal adhesion and compliance with fire safety regulations.
Application time depends on surface area, number of coatings, and fire resistance rating required. Small-scale projects can be completed in 1-2 days, while large commercial buildings may take several days. Airless spray application speeds up the process while ensuring a smooth, even finish.
Not necessarily. Fire-retardant coatings come in clear or tinted options, allowing you to maintain the original look of wood or painted surfaces. Intumescent coatings can be left exposed or top-coated with decorative finishes to match your building’s aesthetics.
