Fire Retardant Paints
Fire retardant paints are most frequently used in large scale industrial spaces, public buildings and facilities, or on new builds. They can also be used on smaller DIY projects, but not for those tasks that simply require heat resistant paint, like BBQs and exhaust pipes. Certain substrates and surfaces will require specialist fireproofing coatings, such as varnishes or intumescent paint.

Fire Retardant Paints – Where to Use It, and Where Not To
Fire retardant paints are coatings applied to various materials, primarily wood and wood-based products, to enhance their fire performance. These paints are part of passive fire protection measures, such as fire stopping, which do not require activation to function effectively. Fire retardant paints improve the reaction to fire performance of the surfaces they cover, helping to prevent the spread of flames and reducing the heat released during a fire.
Fire retardant paints are crucial in improving the fire safety of buildings and structures by enhancing their resistance to fire and controlling the spread of flames. There are several types of fire-retardant paints, each designed for specific applications and materials. Here is an overview of the different types, their applications, and typical uses:
Fire Retardant Paints FAQs
Do Fire Retardant Paints Comply with UK Building Regulations?
Yes. Fire retardant paints are tested to recognised standards, including BS 476 and EN 13501, to help meet fire safety requirements. However, full compliance depends on the entire system and structure, not just the paint alone.
How Long Does Fire Protection from Intumescent Paint Last?
Most systems offer fire resistance for 30, 60, 90, or 120 minutes, depending on the product, thickness, and tested system. The duration must match the fire protection rating required for the building or structure.
Can Fire Retardant Paint Be Overcoated with Decorative Finishes?
Yes, many fire retardant coatings allow for overcoating with approved decorative finishes, such as water-based emulsions or flame-retardant topcoats. Always check compatibility before applying additional layers.
Is Fire Retardant Paint a Substitute for Other Fire Protection Measures?
No. Fire retardant coatings are part of a wider passive fire protection strategy. They do not replace alarms, sprinklers, or compartmentation but can enhance fire resistance of materials.
How Is the Correct Thickness of Fire Retardant Paint Determined?
The required thickness is calculated based on substrate type, fire rating, and material dimensions. For intumescent coatings on steel, for example, a loading table or bespoke specification is needed.
Does Fire Retardant Paint Require Professional Application?
Some systems can be brush- or roller-applied by competent tradespeople, but complex projects—especially on steelwork or in high-risk buildings—should be handled by trained fire protection contractors.
