Intumescent Paint Contractors Services
Galco can apply any intumescent coatings to meet your required specifications. As a passive fire protection coating, it can come in R60, R90 & R120 which provides up to 60, 90 or 120 minutes of fire protection for structural steel.
We apply it in-house using our new plural-component spray equipment, which allows reduced waste. Thanks to the unique characteristics of intumescent paint, it allows Galco to offer quick turnaround times.
Both Sherwin Williams products come in ‘Light Grey’, however, we are able to provide additional colours that can be applied as a topcoat to meet any visual or aesthetic requirements.
Although intumescent coatings have a life cycle of 20-25 years and shouldn’t require any additional reinforcement once applied, we are happy to offer on-site inspections and touch-up method statements if required to ensure total fire protection.

590°C
In only 3.5 minutes, the heat from a house fire can reach over 590°C.
2-4 hours
Intumescent products provide 2-4 hours for occupants to escape.
What is passive fire protection?
While active fire protection systems, such as sprinklers, can extinguish fires, passive fire protection is designed to prevent the spread of fire and contain it in defined compartments to minimize damage and – even more importantly – to allow people in other compartments time to evacuate safely.
In the event of a fire, the heat and smoke will spread through penetrations and joints in the walls and floors, causing damage, endangering people and potentially also blocking escape routes.
Passive fire protection coatings are reactive, meaning that when the intumescent coating comes into contact with fire or extreme heat the coating starts to expand, producing a protective charcoal layer around the steel, preventing it from collapsing.
Intumescent passive fire protection solutions are designed to be able to seal all different types of building joints and penetrations, in order to help keep fire in defined compartments for a certain period of time, thereby allowing people to evacuate safely.
How do intumescent paints work?
Steel doesn‘t burn but under full weight it loses its stability at about 500/550°C.
If the period up until the attainment of the critical temperature of the structural component fails to comply with the fire resistance period required by the Building Regulations, protective measures must be taken
An intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescent materials used in fire protection will increase their volume significantly under the influence of heat (typically at 300°C – 500°C).
This physical process is one of the main principles for passive fire protection products: Intumescent sealants are able to close gaps in and around service penetration seals very quickly in the event that a fire occurs.
The purpose of intumescent products is the prevention of the structural collapse of the building, which can occur if load-bearing steel elements reach a critical state.
Benefits of Intumescent Paint
- Fire-proofing – intumescent paint work as a fire proof, providing essential additional time in case of an emergency.
- Prolonged life – intumescent paint prolongs the life of structural steel surfaces.
- Insulation – intumescent paint acts as an insulator, protecting structures from damage and deformation.
- Aesthetics – intumescent paint provides an aesthetically pleasing wherever it is applied but particularly on structural steel surfaces.
- Limits the spread of fire by containing it in a single compartment in its area of origin
- Slows the spread of toxic gas and black smoke, allowing people more time to escape more safely
- Provides vital escape time for people during fire incidents
- Protects escape routes, building structure and critical structural members
- Minimizes costs to rebuild after the fire
- Protects owners’ built assets
