FAQ
Answer 1 - We have a large balcony project and the Architect has requested that it be painted after Hot Dip Galvanising. We have heard that most paint will not adhere directly to freshly galvanised steel. Is this true and how should we overcome this problem?
In general most paints will not adhere to freshly galvanised steelwork. The traditional method was to etch the surface with etch primers, T-wash or by a light sweep blast. All of these are expensive and in the case of some primers can be unpleasat to work with and cause environmental issues.
Thankfully this is no longer necessary. Ongoing research and development has led to the introduction of Galvacoat, a top quality paint that will adhere directly to freshly galvanised steel. This two pack polyurethane paint is readily available in all RAL and BS colours and is simple to apply by spray or brush.
Galvacoat has been approved by Dublin Corporation and specified by many top practices. There are several high profile applications where Galvacoat has been used details of which can be found by clicking on the ‘Case Histories ’ section of this website or on the links below.
Questions
Question 2 :
How long does it take to galvanise steel?
Question 3 :
Can I specify a thicker coating than normal and if so, will I achieve a correspondingly increased lifespan from my steel?
Question 4 :
We recently had to carry out some remedial work on site, prior to erecting a Hot Dip Galvanised steel structure. The architect on the job was concerned that we might have intrinsically damaged the corrosion protection of the steel. Is this the case ?
