Frequently Asked Questions

Here we answer the most frequently asked plating questions. If you have a question that has not been answered below, please get in touch and we will add it to our list.

Is plating expensive?

Plating is inexpensive to do but the costs vary depending on the price of the metals you wish to plate with. For example, plating something the size of an  iPhone with enough gold to be hard-wearing costs £8 - £10 worth of actual gold. However, plating the same sized item in nickel or copper costs pennies.

Is plating difficult?

Plating is surprisingly easy to do and to make it even easier, out kits contain a tutorial which should get you up and running within 30-40 minutes of setting up your kit. As well as this, we provide unrivalled technical support via phone or email at no extra cost.

Is plating hazardous?

It is easy to be safe around the chemicals used but best practice is advised. Good ventilation is always recommended when working with chemicals and you must wear appropriate PPE (see product pages for more information). We will also provide full SDS sheets with your purchase. Providing you follow the instructions given and keep the chemicals out of reach of children and pets, they can be used safely.

Which kit do I need?

We have lots of options and the kit that is best for you will be largely determined by the things that you wish to plate, their size and their composition. We have written an article to help you decide: How to Choose a Kit.

What is the difference between electroplating and electroforming?

Electroforming is the process of turning a non-conductive surface into a metal surface which can then be electroplated in whatever finish you choose. Electroplating only happens on metal surfaces. For more details, please see our article: Electroplating v Electroforming.

How long will plating last?

The longevity of plating depends on three things. Firstly, the thickness of deposit - items with a thicker plate will resist more wear than items plated with the same metal with a thinner finish.

Secondly, If items are subject to lots of abrasion and rubbing, e.g. items that are worn such as jewellery or items such as phones, the plating will show signs of wear and tear faster.

Thirdly, different metals have different rates of wear e.g. an item which is gold plated will not stand up to as much abrasion as the same item plated in nickel. This is because nickel ranks higher on the metal hardness scale than 24K gold.

Please note: our G.S.P 24K Gold Solution is cobalt hardened and is designed to be more hard-wearing.

What is the difference between 24K gold and 18K gold?

24K gold is pure gold whereas 18K gold is 75% gold and 25% other metals. The two solutions are designed for different applications and there is a slight colour difference in the deposited gold, 18K gold is a little paler in colour.

24K gold is used for most decorative gold plated finishes and is the most popular gold finish. 18K gold can be used to match existing gold colours in items that are being restored. The primary function of our G.S.P 18K Gold Solution is to act as a 'gold strike' which allows for the easy tank plating of steels.

What is gold strike?

‘Strike’ is a term applied to plating solutions that prime the surface of certain tricky substrates such as stainless steel, so that tank plating can happen more easily.

What is the difference between rhodium plating and white gold plating?

Rhodium is a white metal which is used to finish off rings and other jewellery that is made from white gold. It has a brilliant white hue and catches and reflects light extremely well. Rings that are said to be white gold are almost always plated in rhodium, hence their brilliant white appearance.

White gold has an off-cream, almost yellow colour and when white gold rings are said to be ‘yellowing’, this is in fact due to the natural colour of the white gold showing through the brilliant white rhodium plate which has worn away.

Can brush plating do everything that tank plating can?

No, there are certain items that can only be tank plated such as non-conductive surfaces, aluminium, non stainless steels, and most zinc-based metals. However, it is certainly true that brush plating can give you just as good a finish as tank plating if all the prep work is done, and the metals that you are working with are suitable

What is the shelf-life of the chemicals available on this site?

The only products that have a particularly limited shelf life are the G.S.P Gold Polish and the G.S.P Compound Polish, but even these are quite long lasting. Over the course of around 2 years, however, they will start to separate and will need replacing.

All other plating solutions and prep chemicals have a shelf-life of many years.

Can I reuse my chemicals?

Yes, all of our chemicals are designed for use over and over. If brush plating, work over a pot or catch tray to retain as much run-off as possible so that it can be reused. This is true both for prep chemicals and for plating chemicals.

How should I store my chemicals?

Chemicals should be stored in a clean, dry, space which is out of the reach of children and pets. Do not expose your chemicals to strong sunlight or allow them to freeze.

Once I have purchased, what is the aftersales service?
