Cold galvanizing or Make up ?

The literature on cold-galvanising products is extremely dense. Manufacturers and distributors alike release documentation that is, more often than not, sales-oriented. For economic reasons, the vast majority of these aerosols are packaged using liquefied butane or propane gas. Aside from the hazards of these extremely flammable and explosive gases, with a flash point of -58°C, the concentration of the active galvanising ingredient is very low, at around 20-30%. This results in a low cost price and, accordingly, a low retail price. However, only a small surface area can be treated. The real cost is far from clear. Manufacturers rarely commit on this score, with the more reputable stating coverage of 1.2 m² to 1.8 m². Weighing the aerosol before use is very revealing. The primary function of a cold-galvanising product is to protect against corrosion. There is a standardised method to test the performance of a protective anti-corrosion, as set out in the ISO 9227 and ISO 4623-3 standards. Few manufacturers guarantee the performance of their products, considering that in the majority of cases, users require galvanising products for touch-up work; this is known by professionals as "make-up". Nor do they back up these results through test reports carried out by certified laboratories.

We subscribe to different values.
