Application Process:

Proper application of HempaFire Pro is essential to achieve maximum fire resistance and long-term durability. Follow these easy steps to ensure correct installation on different surfaces like wood, metal, and concrete.

Step 1: Surface Preparation

• Clean the surface thoroughly to remove dust, grease, oil, or loose particles.

• For steel or metal, remove any rust using sandpaper or a wire brush.

• On concrete or plaster, ensure the surface is dry, fully cured, and free of moisture.

• Use a suitable primer if required (consult technical data sheet).

Step 2: Mixing the Product

• Stir the HempaFire Pro coating thoroughly before application.

• Use a mechanical stirrer to achieve a uniform and lump-free mix.

• Do not dilute unless recommended by the manufacturer.

Step 3: Application

• Apply the product using a brush, roller, or airless spray.

• Maintain a consistent wet film thickness as specified in the datasheet (typically 300–400 microns).

• Apply multiple coats if required, allowing drying time between layers.

• Ensure good ventilation during and after application.

Step 4: Drying and Curing

• Allow each coat to dry completely (usually 4–6 hours per coat at 25°C).

• Final curing may take up to 24–48 hours depending on humidity and temperature.

• Avoid exposing the coated surface to water or mechanical stress before it’s fully cured.

Safety Precautions:

• Use protective gloves, eyewear, and a mask.

• Keep the area well-ventilated during application.

• Store the product in a cool, dry place, away from direct sunlight.

Application Tools Required:

• Paintbrush / Roller / Airless Spray

• Stirring stick or mechanical mixer

• Sandpaper or wire brush (for surface prep)

• Primer (if applicable)

Hempacore and Hempafire intumescent products have been tested, assessed and certified for a range
of approvals for the fire protection of structural steel. Please consult the Product Data Sheet for more
information. For latest information about country specific approvals, please contact your local Hempel
representative.
Reference throughout this document is made to industry best practice guidelines such as “European
Industry Best Practice Guide on the application of intumescent coatings to constructional steel –
CEPE/EAIPC/EAPFP 2015” and ASFP Technical Guidance Document TGD11 “Code of practice for
the specification & on-site installation of intumescent coatings”.
For the primers and topcoats used as part of the Hempacore and Hempafire coating systems, data
can be found in the relevant Product Data Sheets and the “Hempacore / Hempafire Cellulosic PFP
Approved primer/topcoat” list.
Storage conditions: Hempacore and Hempafire single pack solvent-borne products must be kept/stored in dry areas,
always protected from direct sun light and frost, during storage and also during transport. During
storage, containers must remain sealed.
Recommended storage and transportation conditions are between 5°C and 40°C. The shelf life of the
product may vary depending on the storage conditions.
To facilitate the spraying of the product, it is recommended to store it between 15°C – 25°C-conditions
for at least 12 hours before the start of the application.
The shelf life of each product can be found in the corresponding Product Data Sheet (PDS).
Substrates and surface
preparation
Hempacore and Hempafire single pack solvent-borne products can be used for the fire protection of
structural carbon steel and other structural metallic substrates that are covered in their approvals,
depending the product this may include galvanised steel, stainless steel and thermally sprayed
aluminium and/or zinc.
For each substrate, only certain primers at a specified film thickness can be used. Specific details can
be found in the corresponding Product Data Sheet and the “Hempacore / Hempafire Cellulosic PFP
Approved primer/topcoat” list. Please contact Hempel for specific information.
On carbon steel a cleanliness of Sa2½ must be achieved with a surface roughness of Medium (G)
(ISO 8503-2) prior primer application. for further details see Hempel’s Technical Guidance for Surface
preparation guidance. ST3 cleaning prior primer application is only allowed for repair areas, and
restricts the primer selection. Galvanised and metallised steel require separate approval which is
intumescent-product specific. Contact your Hempel representative for details on approved substrates,
surface preparation and primers supported.
All relevant substrates to be coated with Hempacore or Hempafire single pack solvent-borne products
must be clean, dry and free from contamination. Dirt, salts, oil and grease have to be properly removed
with suitable detergent and high pressure fresh water cleaning.
Primers: Hempacore and Hempafire single pack solvent-borne intumescent products must always be applied
over an approved primer or primer system which has been tested for compatibility and performance in
fire scenarios.
Hempacore and Hempafire single pack solvent-borne intumescent products may under no
circumstances be applied directly to the steel or substrate’s surface.
