Our gold brush plating solution is ideal for decorative and functional applications including jewellery, electrical contacts, gold plating on plastics and much more. Gold concentration: 8 grams per litre. It plates a 24 karat layer of gold.

If you need to gold plate on a base metal such as copper, you will need to plate a barrier layer of either nickel or palladium. Links to these solutions can be found in the ‘Related Products’ section below this tabbed panel. Please click on the ‘Read Manual’ tab of this tabbed panel for fully illustrated guides on gold plating.

This solution plates a shade of gold with a slightly redder hue which approximates to between the Swiss watch industry standard of 2N and 3N.

Our Gold Brush Plating Kit is a great choice to get started with gold brush plating. It includes 50ml of this gold brush plating solution and is based around our EasyPlater. This power source is designed and made by us at Spa Plating and is really straightforward to use.

This gold brush plating solution is ideal for personal items, as it’s so hard wearing. Click HERE for a handy reference table for advice on pre-treatment stages for gold brush plating. To work out how much gold solution you will need and how much it will cost to plate your item, please click on the ‘Calculator’ tab above and select ‘Gold Brush Plating Solution’.

Whether the gold plate is shiny or matt in appearance depends on the condition of the surface you’re plating on to. If the underlying surface is matt, then the plate will be matt; if shiny, then you’ll have a shiny plate.

The shade of our Gold Brush Plating Solution can be bleached back by mixing it with our Gold Whitener. The top earring has been plated with our gold brush solution mixed with the Gold Whitener. Please click HERE to see Gold Whitener.

Our Gold Plating Solution is great for the selective gold plating of items such as antiques.

Gold brush plating a tap in situ. You can gel up your plating solution with our Thickener. This is ideal for plating on site as it stops your solution from dripping and running away. Click HERE for an overview of brush plating in our Electroplating Manual.

You can work out how much gold plating solution you’ll need and how much it will cost with our on-line Gold Brush Plating Calculator. You’ll find a link to this and other plating calculators in the main menu at the top of our website.

Back to Product Description

Gold Plating Solution has been formulated to be one of the hardest wearing and fastest gold brush electroplating solutions available. This fact, coupled with its fantastic coverage, makes it our best selling product. We incorporate a preservative into the mix which gives it a very long shelf life, leaving the gold in the the solution and not at the bottom of the bottle as with some other gold plating chemicals.
Gold content: 8 grams per litre.

Surface preparation for brush plating gold and silver - a quick reference

This section includes a handy quick reference table to show you which pretreatment stages you need to go through on which metals to prepare for gold and silver plating.

Please refer to the table below for preparation options

Please note;

  • A lot of surfaces can be easily prepared by rubbing with MPU and buffing with a clean paper towel.
  • In the table below, where is says ’Gold Flash’, this means to plate a thin layer of gold – usually around 0.01 micron thick – using our Gold Flash solution.
  • For areas that are difficult to reach with MPU or are highly textured, electroclean and electro-activate all in one with our unique ActiClean.
Base Metal Gold Plating (includes rose and green gold made with our Coloured metal Mixers) Silver Plating
Copper, brass, bronze and its alloys 1.MPU or ActiClean or Cleaner 2. Plate a barrier layer of nickel, palladium or white bronze 3. Gold plate 1. MPU or ActiClean or Cleaner2. Silver Plate

Tin and its alloys (pewter, Britannia metal and solder) 1. MPU 2. Plate with some freshly pre-mixed white bronze plating solution using our White Bronze Mixer and our Copper Brush Plating Solution (Use within one hour after mixing) 3. Gold plate

2. Copper plate with either PP Copper, Copper Strike or Copper Brush Plating Solution, nickel plate then gold.

Despite its name, EPNS (Electro Plated Nickel Silver) does not contain any silver, but is an alloy of copper (60%), nickel and zinc.

Monel metal is an alloy of nickel and copper, with some iron added for strength.

How to use this calculator :

1. In the first box, enter the thickness that you want to plate to in microns (thousandths of a millimetre).

2. In the second box, enter the surface area of the article in square centimetres (cm2).

3. In the third box, enter the type of swab you are using.

4. You will notice that in the fourth box, the Calibration Factor is defaulted to 1. This can usually
be left as it is. You can read more about setting the calibration factor for more accurate results
in Note 1 below.

5. Click the ‘Calculate button’.

6. Read off the volt setting and the volume of solution that you will require.

7. Next is the coulomb reading that you will need to plate to. (See Note 2 below).

8. Amp-hours are also quoted below the coulomb reading and is an optional readout on the MicroPlater.
Amp-hour reading are available for coulomb readings above 10 coulombs.

9. The weight of gold plated and the percentage of gold remaining in the solution are displayed
in the final two boxes.


  1. When plating a number of identical items, the calculator can be calibrated to give more accurate results
    but applying a calibration factor. This is calculated by dividing the calculated thickness or weight by the actual thickness or weight.
    Note that if you’re using the weight method, you will require suitably accurate scales. Calibration Factor = calculated thickness or weight/actual thickness or weight.
    For example, the calculator reads that the weight of plate should be 0.32 grams when plated to 2.5 microns. The actual weight is measured at 0.35 grams.
    The Calibration Factor is: 0.32/0.35 = 0.91
  2. Be careful not to create a short circuit as this will cause inaccurate results or may invalidate them completely.
