Right primer, right topcoat, applied inside the recoat window and in the right conditions. Any coating looks right on the day it is sprayed. The question is whether it is still holding twelve months into service.
A coating system is chosen against two things: the environment the plant actually works in, and how long you need it to last. Not what is on the shelf, and not what was used last time.
That means a machine going to a coastal site gets a different system to one working in a sheltered inland yard, even if the client wants the same colour. We will explain the difference and let you decide.
“Even colour, sharp lines, and components finished down to the wheels and steps.”
What finished actually meansTell it where the plant works and how long you need the finish to last. It will give you the corrosivity category, an indicative preparation grade and a starting point for the system. Useful for scoping a job or sanity checking a quote you have been given.
| Reference standard | AS/NZS 2312.1 — protection of structural steel against atmospheric corrosion by protective coatings (paint). |
|---|---|
| Corrosivity | System matched to the corrosivity category and the design life specified, per ISO 9223 categories C2 to C5 and immersion classes. |
| Film thickness | Dry film thickness checked against the specification and recorded. |
| Recoat window | Each coat applied inside the manufacturer's stated window. Outside it, adhesion is a gamble. |
| Conditions | Substrate temperature, dew point and humidity considered before application, not after. |
Anyone can spray a flat panel. The difference shows up on the steps, the wheels, the handrails and the bits an inspector actually puts their hands on.
Spray application has real constraints. Better you hear them now than after a start date is locked in.
| Mobile application | We work at your site or yard. Without a fixed booth, ambient conditions matter and weather affects scheduling. A workshop is planned. |
|---|---|
| Isocyanates | Two pack polyurethane contains isocyanates. Application requires exclusion zones, respiratory protection and controlled access. It affects who else can be on site. |
| Overspray | Adjacent plant, vehicles and structures need masking or separation. Site layout drives the method. |
| Colour matching | We match to brand and fleet colours. Exact matches to a weathered existing finish are not always achievable, and we will say so. |
| Certification | We are not a certified coatings inspector. Where a project requires third party inspection or NACE/ACA certified sign-off, that is engaged separately. |
Send it through. If we cannot achieve it we will tell you before you commit, not after.
