EQUIPMENT EQUIP MENT AND MATERIAL MATERIALS S
For brush plating Take a little time to get to know your equipment and materials by looking through this step-by-step guide we’ve put together. It will help you to familiarise yourself with the most important items in your kit, giving you the practical knowledge to get started on the rst plating projects, which are introduced later in this manual.
The Power Plating Rectifer FRONT VIEW
Main features;
Voltage adjustment (3v - 15v, max 25 amps)
compact and lightweight used as easily for on-site jobs as in your workshop.
Digital display (volts and amps) Power indicator
Vaiable voltage (fom 3v to 15v), max 25 amps - you’re in full control of the power level, letting you tackle the smallest to the largest of jobs with condence. Safety - the overload and radio frequency interference protection means you can use the rectier in any environment.
BACK VIEW On/Off switch
Power input socket
Output socket - negative Output socket - positive Cooling fan intake grille Red lead (this end to be plugged into red socket on rectier) Electrode Handle Electrode
The electrodes, swabs and leads Swab
Main features; The electode handles have been specially designed to be comfotable to hold in the hand. Because the electrodes are made from top quality mateials, they plate excellently, are hard-wearing and present no risk of contamination. The swabs have been specically designed to hold the plating solution efciently and to be e-usable. Once you have nished plating, you simply rinse them out in tap water and allow them to dry.

Main features This electrode is much broader and atter than the normal electrodes and allows you to process large, at areas more evenly and quickly. This electrode should only be used for plating very thin, or ‘ash’, layers of gold and not for normal gold plating.
The Pen Plating Kit This end of red lead plugged into end of plating pen
Main features; The pen plating rectier is ideal for supplying power for smaller, precision plating jobs. The digital display is brightly lit and clear and the red and black leads plug into the red and black sockets on the front, similar to the Power Plating Rectier. The other end of the red leads plug into the ends of the plating pens.
Plating pens and perspex stand (design unique to Spa Plating)
The mini contact pobe connects to one end of the black lead, while the other end of the lead plugs into the black socket on the rectier. By touching the end of the contact probe to the surface of your work, you complete the electric circuit and plating takes place.
Back-lit digital display
The clea pespex stand povides a handy docking area to keep your plating pens organised.
Knob for controlling voltage
The plating pens come with two types of tips. Use the felt tips for rough surfaces and spot repairs where precision is important. The cotton tips deposit a solid layer of plate quickly and efciently.

Ultrasonic cleaner Main features; Efcient cleaning - this piece of equipment is very useful for cleaning smaller, delicate items that have areas that are more difcult to get at, such as jewellery and cutlery. Sonic action - it works by bombarding the object with air bubbles and ultrasonic, which dissolve the dirt into the water. Vaiable settings - you can control the intensity of clean by varying the time, from 90 - 480 seconds.
Conductivity tester Main features;
Digital display (counts down time of clean in seconds)
Time save - this is used to test whether the surface you want to plate is conductive or not. Sometimes metal can be nished with a thin, invisible layer of lacquer to stop corrosion. If you don’t know it’s there, it could mean you waste a lot of time trying to plate something, when it can’t be plated. Multi-functional - not only can the tester be used to establish conductivity, it can also be used for diagnostic tests on your electrodes, leads and rectier.

SOLUTIONS AND POLISHES All of Spa Plating’s solutions have been specically developed for the process of brush plating. Over the past twenty years, we have concentrated our efforts into researching and developing formulations that offer optimal performance especially for this process.
Polishes and solutions used for the preparation of metal surfaces for plating
An excellent example of our commitment to on-going R&D is our new preparation product, MPU. Up until now, anyone starting off in brush plating has been advised to electroclean and activate or both. With MPU, in a lot of cases, these stages become unecessary, as all you have to do is rub the surface of your work with MPU, clean off with a paper towel and get straight on with the plating. This saves signicant amounts of time, effort and space; all very important considerations when setting up your brush plating business for the rst time.
Preparation Preparatio n solutions It is pefectly possible to replace the electrocleaning and activating stage with MPU, when preparing nickel containing alloys such as stainless steel. Cleane - this solution is a very effective de-greaser and also removes the oxide layers which build up on metals, such as silver and copper. Activato - this is particularly useful for removing the strong oxide layer that quickly builds on nickel and nickel containing alloys such as stainless steel which prevents successful plating. Deionised wate - this is water in its purest form, with all traces of solid matter ltered out. Use this to rinse between each application of solution, to prevent cross contamination and ensure a good plate. Chome stippe - use this to remove old layers of chrome, before you start plating on top.
Brush plating solutions
Gold and silve is by far the most popular choice for brush plating, for obvious reasons. However, other metals play a vital role in brush plating; Bronze Mixer can be combined with copper solution to plate a range of shades from a light gold (or 2N) through to a brilliant white bronze which can be used as a chromium substitute. The applications for our plating solutions are huge and cross a very wide range of industries, from decorative items such as jewellery,, to large industrial processes such as jewellery the restoration of printing rollers with copper plate. All of these applications are open to you, the brush plater, and with experience and practice you will be able to tackle many of these jobs with condence.

SOLUTIONS AND POLISHES: continued
Preparationss for plating solutions Preparation This goup of solutions is designed to change the colour or shade of gold by adding small amounts of these to our gold brush plating or pen plating solutions. You can change the colour of gold to white or vary the shade from 24 to 18 or 9ct. The lage white bottle in the centre of the picture is a bottle of thickener. Adding equal amounts of this powder to your plating solution turns it into a gel. This cuts down on wastage, as very little solution runs off the piece you are plating. There is also less mess, which may be an important consideration if you are plating on-site, in someone’s bathroom!
Gold Pen Plating Solution This is anothe example of how our solutions have been tailor made for the brush and pen plating process. The Gold Pen Plating Solution has been specically designed to work with optimum efciency with our Battery Pen Plater and delivers a rich layer of gold every time. Mixing it with thickener will help you plate small, hard to reach areas on electrical equipment or pieces of jewellery.
Polishes fom a vital pat of the brush plater’s kit, as they help you to create the optimum surface for successful plating. We sell polishes for both hand and machine polishing. The blocks of machine polishes are not included with any of our kits but can be bought on-line, via our web site, along with the polishing machines.
Polishess and fnishing compounds Polishe
It is possible to polish and clean items ready for plating without using a polishing wheel. This depends on the initial condition of your work and how much time you are willing to spend. MPU, our polish designed for preparing the surface of your work, will clean it of traces of wax and silicone and also polish the surface to an acceptable shine. MetaSeal is designed to be used after you have plated, to seal the surface of your work and slow down the process of tarnishing.
5
An overview of the Brush Plating Process Brush Plating can be broken down into
3 separate stages......
1
Surface Preparation
The more attention you pay to polishing and cleaning at the start, the better your end result will be. Make sure your work is perfectly clean by using our range of preparation polishes, in particular MPU, and your work will turn out perfect and patch-free. Just remember that plating can’t hide deep scratches, so for a scratch free nish, make sure you polish these out before you start. If you are lucky, your work won’t need polishing at all, and you can go straight ahead with simply cleaning b efore plating.
2
Plating/Stripping
This is the stage where you start start using electricity from your rectier to plate or strip your work. Please note however, however, that stripping is only necessary ne cessary if the part you wish to plate is already already chrome plated. You can also activate activate and electroclean at this stage, although with MPU, activating and electrocleaning has in most cases become unnecessary. Keep rinsing with deionised water throughout, to avoid cross contamination between solutions.
3
Finishing
This stage is quite simple and straightforward as it usually involves sealing the surface of your work with Meataseal.

Brush plating
An introduction to
Preparing the surface of your work
KNOW HOW 1
There are two main stages in preparing the surface of your work; the polishing stage followed, if necessary necessary,, by the cleaning/degreasing stage. At the polishing stage you can either choose hand polishing or or machine machine polishing, depending on how scratched the surface of your work is.
Hand Polishing Choose this for smaller, lightly scratched items. •Wear protective gloves. •We recommend starting off with an abrasive polish, for example, Autosol. Then move on to our MetaPrep polishing compound using kitchen paper towel or cotton wool pade, as in the picture opposite. To make sure the surface of your work is spotlessly clean and ready for plating, go onto the cleaning/degreasing cleaning/degre asing stage, outlined below. For in-depth guidance on hand polishing, please refer to the page ‘Hand polishing and cleaning’ later in this manual.
Machine Polishing Choose this if the item is large and/or deeply scratched. •Wear a visor, visor, gloves and tie loose hair back. Don’t wear loose loos e tting clothing or jewellery. •Bring the work up to the mop, using only the bottom section. You may have to work through two or three stages of polishing, changing mops and corresponding polishing bars. The table below gives guidance on which polishing bar to choose. To see examples of the various mops and polishing bars, refer to the in-depth section on polishing further on in this manual or our web site. once the item is polished, go onto the cleaning/degreasi cleaning/degreasing ng stage.

Degreasing/Cleaning/Activating If your work isn’t too dirty after the polishing stage (and this may well be the case after hand polishing), just clean it thoroughly with MPU. If, however, the work is very dirty with polishing
The bottom half of the copper sheet is now completely grease free with water running off compound from the in a smooth, unbroken bufng wheel, clean sheet. The water dropwith MetaPrep as outlets on the top half show lined above, or rub there is still grease on the work all over with plenty of neat washing up liquid, then rinse off the surface. Wash and rinse again with detergent if this is the case. This is how your work should look thoroughly under running water. water. before continuing with the metal plating stage. Finish cleaning with MPU.

Try out our step-by-step projects At Spa Plating, we understand that starting off with a new process can be bit daunting, so we’ve put together a number of projects designed to take you through the basic techniques of brush plating. The projects are graded, so that the rst one or two are designed to build your condence in the basic skills you need and the subsequent projects gradually tackle more advanced skills. The projects include; 1. Chrome stripping and gold plating
2. Silver plating on copper 3. Gold plating a stainless steel mobile phone cover 4. Using MPU to speed up the plating process 5. Using thickener when stripping and plating a bathroom mixer tap 6. Silver plating an antique EPNS matchbox 7. Chrome plating a brass door handle 8. Selective gold plating on zinc 9. Silver plating an antique pewter ink well We are constantly adding more project pages to this manual, so keep in touch with us to see if we have added any new projects that might be of interest to you; we will be glad to send you an up-date in the post.

Introduction This project is designed to introduce you to the basics of brush plating. By following this guide, you will learn how to clean metal for plating, strip chrome plate, activate the surface of metal ready for plating and nally gold plate.
project 1
Chrome Stripping and Gold Plating
If you want to plate something that has already been chrome plated (for example a bathroom tap), you’ll have to strip off the chrome rst. The reason is that it’s almost impossible to plate any metal onto chrome. NB - You don’t normally have to activate copper before plating; all you need to do is rub with MPU. However, However, if you have to strip off the chrome on a tap for example, chrome is often plated over a layer of nickel or onto a nickel containcontain ing alloy. Nickel is one of the few examples of metals that need activating, so for the purposes of demonstration only, we have included activation in this project.
1 What you will need Collect together all the things you will need before you start. Preparation solutions; solutions; activator, chrome stripper, deionised water, MPU. Plating solutions; solution s; gold. Finishing; MetaSeal. Equipment; spray bottle, three beak ers, length of chrome plated copper pipe ( included in the Deluxe and Power Plating kit). Electrodes; one stainless steel, one carbon and one platinum, with the corresponding number of electrode handles.
2 Setup Arrange your work area as shown in the picture. Take three beakers and pour out approximately 10ml of chrome stripper, 10ml of activator and 10ml of gold solution. Place these beakers in this order next to the three trays. Plug the red leads into each other to form a stack (this can be seen in the next picture). Then plug the other other ends of the leads into the sockets in the electrode handles. Mount the stainless steel electrode in one electrode handle, the carbon in the second and the platinum in the third, using the allen key. Place a swab on each electrode as shown in the diagram.
3 Connecting the leads for chrome stripping In order to strip the chrome, you need to reverse the normal current so, as in the picture, plug the black lead into the red socket on your rectier and plug the three red leads into black socket. Grip the chrome plated tubing with the crocodile clip, which is at the other end of the black lead. The T he other ends of the three red leads should already be plugged into the ends of the three electrode handles.

5 Wetting swab 4 Surface preparation Clean your work with plenty of MPU. Spray with deionised water.
Wet the swab thoroughly in deionised water. This helps the swab to absorb the soluton.
6 Chrome stripping 4-6 volts Dip the swab into the chrome stripping solution and brush the surface of your work with the stainless steel electrode using small circular movements. Continue doing this until all you can see is the straw-coloured layer of nickel underneath. Rinse with deionised water water..
7 Connecting the leads for activation In order to activate the surface of your work in preparation for gold plating, you must restore the nor mal direction of current, so plug the three red leads into the red socket and the black lead into the black socket.
8 Activation 6 - 8 volts Dip the carbon electrode into the beaker with the activator in it and move the swab over your work with the same circular movement. Again, rinse your work before the next stage.
9 Gold plating 4 - 7 volts Take up the platinum electrode, dip it into the gold solution and start plating with the same circular movement, working gradually all over the surface of your work. You will need to keep dipping the platinum electrode in the solution to replenish the gold. If your work has sharp cor ners, reduce the voltage while you plate theses areas, otherwise the plate will be too soft and will quickly wear off. Keep plating for at least ve minutes to build up a good layer of gold. Rinse.
10 Finishing To bring out the nal lustre of your work, polish with MetaSeal.

KNOW HOW 2
The electocleaning pocess, sometimes called ‘power cleaning’, is the last cleaning stage and should be done just before you activate and start plating. It is essential only for nickel containing alloys such as EPNS (electroplated nickel silver), cupronickel, monel metal and stainless steel as it gets rid of the very thin, invisible layer of oxide that builds quickly on nickel containing alloys. This oxide layer leads to blotched plating or, at worst, your plating akaking off, so it’s important to remove it with a thorough power clean. MPU has, in most cases, replaced this stage, although it may still be necessary if your item is deeply recessed as MPU may get lodged in the crevices. Monel metal is often used in the manufacture of musical instruments and EPNS is also used for the same, as well as for making table ware and other decorative items for the home. Although EPNS has the word ’silver’ in its name, it doesn’t actually contain any silver, being an alloy of copper copper,, nickel and sometimes zinc. Because the oxide layer builds very quickly on nickel and nickel containing alloys alloys, you must move swiftly from the activation to the plating stage to avoid this. Only a stainless steel electrode should be used for electrocleaning. For activating, use a carbon or platinum electrode.
Choosing
t h e right electrode for the job OUR RANGE OF ELECTRODES ARE MADE FROM A WIDE RANGE OF MATERIALS TO ENSURE YOU GET MAXIMUM PERFORMANCE FROM YOUR PLATING SOLUTIONS. We are sure that once you’re condent about which electrode to use with which process, you’ll soon notice the benets in terms of excellent results and cost savings. Opposite is a quick reference table to get you started with choosing the best electrode to go with your chosen plating process. As well as the table, the notes below will help you further rene your choice.
Choice of Electode Plating pocess Chrome stripping Cleaning Activating
The stainless steel electrode must only be used for chrome stripping and electrocleaning. The carbon electrode is very useful as it can be used as the rst choice for a range of plating processes and is economically priced. However, it will wear with heavy use and tends to discolour the swab. This has no effect on the quality of the plate. The platinum electrode plates to the same high standard as the carbon electrode, but will not wear down or discolour the swab. The main advantage of the of the silver electrode is that by using the same metal electrode as the plating process, you are dissolving metal from the electrode into the plating solution, and plating that metal as well as that from the solution, s olution, onto your work.

Technical tip2
Technical tip1 The silver electrode is called a ‘sacricial’ electrode because it ‘sacrices’ some of its metal into the plating solution during the plating process. This can mean considerable cost savings as you are supplementing your solution with extra metal from the electrode, which makes it go further further.. Very useful if you’ve got a large silver plating job to do!
12
Waning! Do not try to clean your platinum electrode with an abrasive cleaner. To remove any marks that can’t be easily wiped off, connect the wand handle that has been tted with a platinum electrode to the red lead and join a stainless steel electrode (with a swab) to the end of a black lead and brush at 6 volts with Activator. Carry on brushing until all marks have been removed.
