Steps for fireproofing with intumescent paint
Fireproof and intumescent paints are a specialized type that require a good usage plan for proper use. In fact, the main intumescent paints can only be handled and used by certified and approved companies. Their costs are high but will provide protection against fires.

1. Assess the surfaces to be protected
The first step is to identify all areas requiring fireproof paint treatment, such as wooden beams, pillars, walls, and metal structures. This assessment determines the scope of work and total budget, which can range from 800 € to 15,000 € depending on the extent of surfaces to be protected.

2. Request quotes from certified companies
Contact multiple specialized fireproofing installers to obtain detailed quotes. Costs vary by surface type: wooden beams from 20 €, pillars from 30 €, and walls from 100 €, making it essential to compare certified offers before deciding.

3. Verify required approvals and certifications
Ensure the company holds required certifications and that the fireproof paint products comply with fire safety regulations. This verification guarantees that the service meets mandatory standards and has legal validity for your property.

4. Prepare and clean the surfaces
Before applying fireproof paint, all surfaces must be thoroughly cleaned, removing dust, rust, old paint, and contaminants. This phase is crucial for ensuring proper adhesion of the fire-resistant coating and preventing additional costs from future repairs.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of fire-resistant paint
Certified intumescent paints have a significantly higher cost than conventional fire-resistant paints. Product quality and certification directly influence the final budget.
Surface area to protect
The square footage to be covered is a determining factor in the total price. Steel structures, wood, concrete, or decorative elements require different amounts of product and application time.
Surface preparation
The initial condition of the material to be fire-proofed affects the cost. If it requires cleaning, sanding, stripping, or prior repairs, the intervention budget will increase significantly.
Number of coats and required thickness
According to applicable fire protection regulations, a specific minimum thickness is required. More coats means more material and labor hours, increasing the final cost.

What is intumescent paint?
Fireproof and intumescent paints are a specialized type that require a good usage plan for proper use. In fact, the main intumescent paints can only be handled and used by certified and approved companies. Their costs are high but will provide protection against fires.
Intumescent paint has a particular characteristic that sets it apart from any other. That characteristic is that when temperature rises due to fire, it swells and creates an insulating foam barrier. This barrier prevents thermal conductivity, so the paint protects the substrate from the action of fire and also from smoke.
General legal aspects regarding fire safety
Fireproof and intumescent paints are a specialized type that require a good usage plan for proper use. In fact, the main intumescent paints can only be handled and used by certified and approved companies. Their costs are high but will provide protection against fires.
Regarding the resistance it offers to flames, it depends on factors such as the type of paint, thickness of the coat, or the surface on which it is applied. That time can range between 30 and 240 minutes.
Difference between fireproof paint and intumescent paint
The general legal framework in Spain regarding fire safety measures is regulated by Royal Decree 2267/2004, which establishes fire safety regulations for industrial establishments, whether warehouses or workshops. Prevention measures are summarized in the Technical Prevention Notes of the National Institute for Occupational Safety and Health (INSHT) through standards 831 and 832.
Special attention must be paid when we are dealing with a building with residential function or if it is an industrial building, knowing which structural elements are required by law to be protected to prevent the destructive ravages of fire. Therefore, reinforced concrete, wooden beams and posts, as well as other steel structures must be properly protected.
The needs for fire protection are covered in the regulations of the Technical Building Code or C.T.E. as it is commonly known, with special attention to section DB-SI. Additionally, the C.T.E. refers to the regulations that each type of business must include, serving as general assumptions. Then you must comply with the specific regulations depending on the Autonomous Community and municipality where the premises or home to be protected with this type of paint is located.
