How to topcoat or paint chrome or metal

Discover our special clearcoat for metals !

This topcoat serves as a adhesion primer and corrosion protection.
Its the only clearcoat that can be applied directly over all metals (silver, zinc, aluminum, steel, galvanized..)
This clearcoat allows to achieve very interesting effects for colouring metals, still keeping the aspect and the grain of the metal, but adding gloss and a colourful depth.

The Celiron topcoat (that’s his name) comes in 14 translucent colours, and also in others

*One can even apply topcoat over chrome and give it colour: To achieve this, read our paragraph below

Painting on metal when its bare, yes, it may seem easy!
but the question we should ask is: Will the paint adhere?

The answer is no, because metals are not a substrate that allows the penetration of paints or clearcoats; there is no adherence.
In addition, the ferrous metals inevitably become rusty by oxidation.

For these two reasons, it is necessary to use an anti-rust adhesion primer.
These products contain silanes or phosphating agents (these are known as very effective “Wash Primer”) that interact with the metal surface,
by chemically transforming it (interatomic bonds), and create the adhesion strength.

Such problems do not occur over a painted metal : in this case, you only have to slightly deglaze then paint directly!

Some chrome paints are specially made to cover directly the metals and play their anti corrosion role.

Identify the type of metal!
It is very difficult to create adherence on-ferrous metals:
alloys, zinc, aluminum, and especially chromium

How to paint over chrome?

This question is regularly put to us.
“Hard chrome” is an extremely tough and impenetrable surface. Needless to say it is very difficult to guarantee an adhesion on this type of surface.
However, Stardust Colors proposes a solution which consists of two processing steps:
– use Derinoxalu, an acidic product that will prepare the substrate, by “opening” it (apply, let stand, rinse and dry)
– apply a high performance primer such as our 714 or 294 zinc-chrome-alu primer
These two special products are available in various packagings here.
