Boston Protect Cold Galvanising Black Zinc 400g

Boston is an Australian brand of aerosol maintenance and protective coating products supplying tradespeople, maintenance teams, and industrial operations with fast-apply aerosol solutions for surface priming, rust protection, and zinc-rich cold galvanising. Their aerosol range is formulated for use on steel and metal surfaces in industrial and construction environments where brush or roller application is impractical or where a fast, portable coating solution is required.

Boston aerosol paints and protective coatings deliver ready-to-use surface preparation and protection in a pressurised spray can, suited to field and maintenance applications where speed and portability are priorities. The range includes aerosol primers for surface preparation and a zinc-rich cold galvanising coating that provides cathodic protection on steel surfaces in place of hot-dip or electroplated galvanising.

Where this product is used

Boston aerosol coatings are used across maintenance, construction, and fabrication:

• Steel surface priming prior to topcoat application in maintenance painting of structures, equipment, and fabricated components.
• Touch-up and repair of galvanised steel where cut edges, drilled holes, or damaged areas require zinc protection to restore corrosion resistance.
• On-site and field maintenance applications where brush or spray equipment is unavailable and a ready-to-use aerosol is the practical solution.

Key specifications

Selecting the right option

Boston Aerosol Paint Primer is the first choice for surface preparation — it provides a bonding layer for topcoats and improves adhesion on clean steel. Boston Protect Cold Galvanising is selected where bare steel must be restored to a galvanised finish — it contains zinc particles that provide cathodic protection comparable to hot-dip galvanising in many service environments. Select can size (250 g or 400 g) based on coverage area required.
