Coating Application
Protective Coating Application in Melbourne
Protective coating application is the process of applying a paint or coating system to a prepared surface so it resists corrosion, wear and environmental damage. We apply specified and non-specified systems — zinc, epoxies, polyurethanes, hi-temp silicones and more — to steel and other substrates, using fully qualified protective coating spray painters. Blasting and coating both happen in house at our Bayswater workshop in Melbourne.
What It Is
Application of Protective Coatings
A protective coating shields the surface underneath it from corrosion, wear and environmental exposure, extending the life of the item. On steel that usually means a system rather than a single product: a primer chosen for adhesion and corrosion resistance, then build and finish coats chosen for the environment and the appearance required.
Because coating performance depends on what happens before the first coat, we blast in the same facility. The surface is prepared and profiled, then coated while it is still clean, rather than being trucked between two businesses in between.
We apply to your specification where you have one — send it through with your enquiry. Where no specification exists, PBC will design a custom specification for your needs.
Step By Step
How the process works
- 1
Send the specification
Send your enquiry with the paint system or specification along with a general arrangement drawing. Photos are always handy but not necessary for project work. If there is no specification, tell us the environment and the finish you need and we will design one.
- 2
Quote and agree the system
We come back with a quote covering surface preparation, the coating system coat by coat, and transport if you want us to arrange it, so the scope is clear before work starts.
- 3
Surface preparation
The item is blasted in our blast room to remove rust, mill scale and old coatings and to leave the profile the primer needs. Preparation is the part that determines how the finished system performs.
- 4
Masking
Threads, machined faces, bearing surfaces, identification plates and anything else that must stay uncoated is masked before the first coat goes on.
- 5
Apply the system
Our fully qualified protective coating spray painters apply the system in order — primer, build coats, finish coats — allowing each coat to cure before the next, as the specification requires.
- 6
Inspection, then collection or delivery
The finished item is checked over, then collected from Bayswater or sent back to you by a courier we arrange at additional cost. Onsite storage lets us hold larger items until you are ready.
Suitability
What surfaces and materials it suits
The systems below are the coating families we apply. The typical uses are written generally: the right system for your item depends on the substrate, the exposure it faces and any specification you are working to, which is what we work through when quoting.
| Coating system | Typically used for |
|---|---|
| Zinc | Corrosion protection on steel, generally as a primer beneath a build and finish coat. |
| Epoxy primers | A high-adhesion, corrosion-resistant first coat on blasted steel, under most industrial systems. |
| High builds and finishes | Building film thickness where a system calls for it, and providing the visible top coat. |
| Hi-temp silicone coatings | Surfaces that run hot, such as exhausts, stacks and hot pipework. |
| Polyurethanes | Durable, colour-retentive finish coats on items exposed to weather, sunlight and handling. |
| Chlorinated rubbers | Chemically resistant coatings for wet and aggressive environments. |
| Alkyd primers and finishes | General-purpose protection and finishing on steelwork in milder exposure. |
| Epoxy and polyester | Tough, chemically resistant coatings where hard-wearing protection is the priority. |
Applications
What it's typically used for
- New structural steel, fabrication and weldments being coated to specification
- Skids, frames and plant being recoated during refurbishment
- Pipe, valve and vessel work in oil and petroleum and process environments
- Industrial fans, dust collection equipment and materials handling gear
- Trailers, decks and truck beds, including non-slip deck coatings
- Streetscape furniture, signage and architectural metalwork
Why PBC
Why choose Profile Blasting and Coatings
Qualified applicators
We have fully qualified protective coating spray painters with the expertise to apply any required specification.
Specification design
If no specification exists for your item, PBC will design a custom specification to suit the substrate, the exposure and the finish you need.
Preparation and coating together
Blasting and coating happen in the same facility at Bayswater, so the surface is coated while it is still clean and correctly profiled.
Broad system range
Zinc, epoxies, high builds, hi-temp silicones, polyurethanes, chlorinated rubbers, alkyds, epoxy and polyester — chosen to suit the job rather than the shelf.
Questions
Protective Coatings FAQs
Our range covers zinc, epoxy primers, high builds and finishes, hi-temp silicone coatings, polyurethanes, chlorinated rubbers, alkyd primers and finishes, and epoxy and polyester. Most industrial work is a multi-coat system rather than a single product — commonly a primer for adhesion and corrosion resistance, then build and finish coats suited to the environment.

Garnet Abrasive Blasting
Garnet abrasive blasting is a surface preparation process that strips rust, mill scale, old paint and contaminants from steel and other substrates, leaving a clean, evenly profiled surface for a protective coating to bond to.

Glass Bead Abrasive Blasting
Glass bead abrasive blasting is a gentler blasting process that cleans contaminants from a surface and leaves a smooth, matte finish rather than cutting a deep profile into it.
