CPCCPD3033 – Apply intumescent coatings

Plan and prepare.

• Review work instructions to apply intumescent coatings.
• Plan all work to meet relevant requirements of work health and safety (WHS), Commonwealth and state or territory legislation, environmental plans and obligations, manufacturers’ specifications, and workplace requirements.
• Select and fit personal protective equipment (PPE) as required for each task.
• Inspect work site, assess hazards and apply risk controls, including required signage and barricades.
• Identify materials appropriate to the work application, calculate quantities and prepare, handle safely and locate ready for use.
• Select tools and equipment, check for serviceability and rectify and report any faults.

Prepare work area and surfaces.

• Set-up area for application processes to suit surfaces to be coated.
• Protect surrounding surfaces with drop sheets, masking or removal of objects.
• Check that where doors, windows and associated furniture are removed they are safely stacked, stored and protected.
• Check work site to ensure provision of adequate ventilation and implementation of precautions to prevent fire and explosion.
• Implement measures to ensure application area remains free of dust and foreign matter.
• Check surface to be coated for sufficient clearance for the expansion of the coating in the case of a fire.
• Strip surface completely of any pre-existing finish.

Apply priming and intumescent coatings to timber.

• Apply priming coat to ensure adhesion of intumescent coating.
• Apply intumescent coating by brush, roller or airless spray, maintaining required temperature and humidity.
• Use measuring gauges to determine wet film thickness.
• Apply top/finish coat to manufacturers’ specifications.
• Protect the finish against abrasion and humidity during drying and curing.
• Use measuring gauges to determine dry film thickness to ensure completed coat meets manufacturer’s specifications.

Apply priming and intumescent coatings to structural metal.

• Blast or wire-brush metal surface to prepare for intumescent coating.
• De-grease galvanised steel.
• Measure the temperature of the surface to ensure it meets the manufacturers’ specifications.
• Apply priming coat to ensure adhesion of coating.
• Apply intumescent coating by brush, roller or airless spray, maintaining required temperature and humidity.
• Use measuring gauges to determine wet film thickness.
• Apply top/finish coat to manufacturers’ specifications.
• Protect the finish against abrasion and humidity during drying and curing.
• Use measuring gauges to determine dry film thickness to ensure completed coat meets manufacturers’ specifications.

Clean up.

• Clean up, meeting all legislative and workplace requirements for safety, waste disposal, materials handling and protection of the environment.
• Clear work area, reuse or recycle materials and place waste and unwanted materials into job waste bins or rubbish stockpile.
• Check and maintain tools and equipment and clean with appropriate solvents.
• Dispose of paint waste and water and solvents used in cleaning tools and equipment in an environmentally sustainable manner.
• Store tools, equipment and sealed unused materials to avoid spontaneous ignition.
