Ensures top quality results for all precious metals including gold, rhodium, platinum and ruthenium
Can be used with other plating solutions
Will not darken the swab (as is the case with a carbon electrode).
Note: It is very important to use the correct electrode. If a stainless steel electrode is used for gold plating, iron from the stainless steel will react with the gold chemical and dissolve into the gold plating solution. This will poison it, making the gold insoluble and not able to plate. This will greatly reduce the efficiency of the solution.
There are three stages to successful Brush plating;
1. Surface Preparation
1. Surface Preparation
The more attention you pay to preparing your surface at the start, the better your end result will be. This first stage can be broken down into three possible further stages; polishing, cleaning and activation. It’s unlikely you’ll have to do all three, it just depends on the type and condition of the surface you’re plating.
Plating can’t hide deep scratches, so for a scratch free finish, make sure you polish these out before you start. If the scratches aren’t very deep then you can do this by hand, using our Hand Polishing Kit. If the scratches are quite deep then you’ll probably need to use a polishing machine. You can buy the polishing compounds for this on our online shop – just follow this link HERE.If you are lucky, your work won’t need polishing at all, and you can go straight ahead with the next mini stage which is…
We recommend cleaning your surface with our MPU. This cleans, polishes and activates all in one, so in many situations, this may be the only preparation stage you need to do! The aim, when cleaning, is to create a water-break-free surface. This process is demonstrated in the accompanying video.
If you’re using our MPU, a separate powered activation stage may not be needed. However some surfaces, such as stainless steel, nickel and nickel containing alloys such as nickel silver can build an oxide layer that is most efficiently removed with a powered activation/cleaning stage using our ActiClean. If you are cleaning larger areas of other kinds of metal then using our Cleaner might be the best option.
This is the stage where you start using electricity from your rectifier to plate or strip your work or if you are only intending to plate small areas, such as a watch cases or belt buckles, you could use our battery powered plating pen with one of our short electrodes fitted. You can plate a wide range of metal finishes, both precious and base metals with the brush plating method. The metal finishes that are available for purchase through Spa Plating include gold, silver, palladium, platinum and rhodium and for the base metals copper, tin and nickel. We are constantly adding more plating solutions to this list as we invest further in research and development.
This stage may need to include stripping before plating if the item you wish to plate has been chrome plated, (for example a bath tap). This is because chrome cannot be plated on to and you’ll need to strip this off using our Safe-T-Strip before you go ahead and plate.
If you’re plating a number of different finishes, for example copper, nickel and gold, you’ll need to rinse the surface of your item thoroughly between layers to avoid cross contamination of plating solutions.
To work out how much plating solution you’ll need you will have to estimate the surface area of your work. The video on the right gives a demonstration of how this can be done.
Silver brush plating on copper
This stage is quite simple and straightforward as it usually involves sealing the surface of your work with our Meataseal.
Total length: 100mm
Platinised length: 75mm
Base material: Grade 2 titanium
Platinum content: 50 g/m2
Titanium base: 99.6% minimum
Operating current density: not more than 80 amps/dm2
pH range: 0.5 – 11
Conditions to avoid: Low pH electrolytes containing fluoride and chloride
Caring for your platinised electrode: Please do not abrade this electrode as this will
damage the platinum layer and considerably shorten its life.
