Martínez Cano, Canarias: Metal protection
In 2023, the metal protection at Martínez Cano, Canarias was made with ProLine PU AL Primer, ProLine PU 1000 TC.
01 · Project overview
What is this project?
In 2023, the metal protection at Martínez Cano, Canarias was made with ProLine PU AL Primer, ProLine PU 1000 TC. The Canary Islands add salt wind to a strong sun. Edges and fixings feel that before the middle of a roof does.
This one is metal protection.
The system named for this job is Krypton ProLine PU C5H.
Krypton Chemical makes the resin. The crew on site applies it. On Martínez Cano, Canarias the details have to get the same film as the open field, and the cure has to finish before the building goes back to work.

02 · The challenge
What did this structure ask of the system?
Steel outdoors fails at the edges, the welds and the fixings, not in the middle of a flat bar. Water sits in a lap, and the coating that was thin there is the first to open.
Martínez Cano, Canarias: Metal protection is that kind of duty. The surface has to be got back to sound metal, the edges striped before the full coat, and the film thick enough that a handrail still has a coating after people lean on it.
03 · The solution
Which system was trusted here?
The system trusted here is the one named for the job: ProLine PU AL Primer, ProLine PU 1000 TC. It is chosen because it matches the substrate and the exposure, not because every building wants the same can.
The build-up is there to survive the exposure this structure actually has, including the lines where workmanship usually goes thin.
04 · Application
How is the system built?
Steel is prepared back to a sound, rough surface. Mill scale, rust and old film that has lost its bond come off. Edges, welds and fixings are striped before the full coat, because those are the places a spray or a roller leaves thin. Salt and dirt are washed off, and the steel is dry before the coating goes on.
The full coat then covers the stripe, at a film that can take a hand and the weather. A walkway is not a roof. People lean on it, chains knock it, and rain sits in the joints. The coating has to be there after that, not only on the day it looked finished.
On Martínez Cano, Canarias: Metal protection the metal is the substrate and the problem. Mill scale looks stable and is not. A coating over scale fails in sheets the first winter. Edges cut in the workshop are sharp, and a wet film pulls away from a sharp edge, so the stripe coat is not optional. Welds are rough and hold moisture. They are cleaned and striped too.
Outdoor steel in this climate cycles every day. The film has to stick, and it has to have thickness left after a year of hands, weather and the odd knock. A walkway is worse than a roof in one way: people touch it. The coating is a barrier first and a colour second.
Inspection is simple and it is visual. Holidays on edges, missed backs of bars, and fixings that were coated only on the face. Those are the places to look before the job is called finished.
05 · Results
What does a job like this stand behind?
Martínez Cano, Canarias: Metal protection has one standard. The coating is still doing its job after the building is back in use, at the details as well as in the middle.
Figures for cure, thickness and strength, where they are given, come from the product data sheets. They are not a test cut out of this building.
What this asks of Martínez Cano, Canarias: Metal protection is workmanship at the difficult line. The open field is the easy part of a resin job. Outlets, edges, penetrations and changes of plane are where thickness goes missing, and where water or wear finds the gap. The same products and the same care belong there, and the cure is allowed to finish before the building goes back into use. That is the difference between a coating that was simply applied and a system that stays in service.

When was the work done?
2023.
Which products were used?
ProLine PU AL Primer, ProLine PU 1000 TC.
Where does a metal coating fail?
At edges, welds and fixings, where the film is thinnest and water sits.
Why stripe the edges first?
A full coat over a bare edge is still thin on the edge. A stripe coat puts thickness where the weather starts.
