Chrome plating is a process that applies a thin layer of chromium onto a metal surface to achieve a mirror-like finish. While professional chrome plating requires dangerous chemicals and specialized equipment, there are a few methods that can be done at home to get a chrome-like appearance on metal objects.

Using Chrome Spray Paint

One quick and easy way to get a chrome look is by using chrome metallic spray paint. This paint contains tiny aluminum particles that mimic the reflective surface of chromed metal. While not as durable as real electroplated chrome, spray paint is inexpensive and can be applied by anyone.

Selecting the Right Paint

There are a few aspects to consider when selecting a chrome spray paint:

Chrome vs Silver – Chrome paint has a blue hue while silver is more gray. Chrome gives a brighter finish.
Gloss Level – High gloss or mirror-like finishes look most like real chrome.
Adhesion – Ensure the paint adheres well to the metal surface being coated.
Durability – More expensive paints hold up better over time.
Brands – Rust-Oleum, Krylon, Dupli-Color and Testors all make quality chrome spray paints.

Rust-Oleum Bright Coat Metallic Chrome is a top-rated spray paint for DIY chrome jobs. It goes on smoothly and delivers a convincing chrome look for less than $10 a can.

Preparing the Surface

Proper surface preparation is key to achieving an even, durable chrome paint finish:

Clean – Use soap and water to thoroughly clean the item first. Remove any oils or residue with alcohol.
Sand – Lightly sand smooth surfaces to help the paint adhere. Use 150 grit sandpaper.
Prime – Apply a coat of primer spray paint so the chrome paint sticks better.
Mask Off – Use painter’s tape and plastic sheeting to mask surrounding areas you don’t want painted.

Taking time to properly prep the surface will allow the chrome spray paint to adhere evenly for a professional looking finish.

Spray Painting Technique

Follow these tips when applying chrome spray paint:

Light Coats – Apply multiple thin coats rather than one thick coat. This prevents drips and runs.
Distance – Hold the can 6 to 8 inches from the surface when spraying.
Motion – Use smooth back-and-forth motions with slight overlaps between strokes.
Rotate – Turn the item as you paint to coat all sides evenly. Use painter’s pyramids for smaller pieces.
Dry Time – Allow at least 24 hours between coats for proper drying.
Clear Coat – Finish with a clear coat paint for added protection and shine.

With some practice and patience, you can achieve a convincing chrome look with spray paint. It may not be as durable as true electroplated chrome, but works well for decorative purposes.

Using a Chrome Plating Spray Kit

For metal objects you want to look chromed both indoors and outdoors, a DIY chrome plating spray kit offers better durability than just spray paint. These kits use a chemical chrome plating process to apply a thin layer of real chromium metal onto a surface.

How Chrome Plating Spray Kits Work

Chrome plating spray kits contain the necessary chemicals, solutions, and tools to electroplate a chrome finish in your own garage:

Degreaser – Removes oils from metal prior to plating
Acid Activator – Etches the surface to accept chrome layer
Cold Chrome Solution – Contains chromium ions that deposit onto object
Current Applicator – Applies electric charge to initiate plating reaction
Rinse – Neutralizes and cleans object after plating

The cold chrome method deposits a thinner chrome layer than professional hot chrome plating, but still provides corrosion protection and a mirror finish.

Safety Precautions

When using hazardous chemicals required for chrome plating, proper safety steps must be taken:

Wear gloves, goggles, mask, hood, apron and boots
Work in a well-ventilated area away from open flames
Follow kit instructions precisely
Dispose of chemicals properly
Avoid contact with skin, eyes and vapors

Exercising caution when handling the acids and solutions will ensure the plating process is safe. Have running water on hand in case of spills.

Applying the Chrome Plating

Follow the steps below to use a cold chrome plating kit:

Clean and degrease item with provided degreaser solution
Activate surface with acid prep solution
Rinse thoroughly and let dry
Attach electrical clamps and submerge object in cold chrome plating solution
Turn on power supply and allow plating action for required time
Remove object and rinse off with water
Apply sealer to protect the chrome finish
Buff item with soft cloth for brilliant mirror finish

When done properly, cold chrome plating can produce results close to professional chrome plating, all from your home garage. The finish won’t be quite as durable, but provides a real chrome coating at a fraction of the cost.

Getting a Professional Chrome Plating Service

For show-quality chrome plating that looks flawless and lasts for years, having professionals do the job is worth the extra cost. The electroplating process uses caustic chemicals and requires experience to master, so hobbyists attempting chrome plating at home often run into problems. Utilizing an established chrome shop guarantees a factory-grade finish.

Where to Get Chrome Plating Done

If you don’t have the equipment and expertise to chrome plate parts yourself, here are some options:

Local Plating Shops – Look for specialty plating companies in your area. They can plate small parts or accessories.
Chrome Shops – These businesses focus specifically on chrome plating for the automotive industry.
Restoration Shops – Many classic car restoration shops offer chrome services for the vehicles they refurbish.
Online Plating Services – Ship your parts to a chrome shop with prepaid return labels.

Searching for “chrome plating near me” is the easiest way to find a provider suited for your specific chrome plating needs.

What Can Be Professionally Chromed?

Many metal components can be chrome plated to restore or enhance their appearance:

Auto trim like bumpers, grilles, wheels
Motorcycle parts like handlebars, exhaust, frames
Metal furniture, light fixtures, appliances
Plumbing fixtures and bathroom hardware
Old tools, machinery, equipment
Musical instruments
Jewelry and decorative metal pieces

Talk with the chrome shop first about the feasibility of chroming the items you have in mind and any special considerations.

The Professional Chrome Plating Process

Professional chrome plating involves a 12-step process to clean, prepare, plate, polish and seal the metal surface. Here is an overview:

Degreasing – Removes all oils and dirt from object
Surface Activation – Use of acids to etch surface
Nickel Plating – Applies layer of nickel to part
Copper Plating – Deposits thin layer of copper over nickel
Chrome Plating – Electroplates chrome layer onto part up to desired thickness
Trivalent Chrome – A newer process that is more environmentally friendly
Brighteners – Chemical baths that increase reflectivity
Rinsing – Cleans part after each stage of plating
Drying – Heat drying to prevent water spotting
Sealing – Clearcoat applied to protect finish
Buffing – Final hand polishing for flawless shine
Assembly – Reassembly of any parts removed for plating

This in-depth process allows chrome shops to consistently produce show-quality chrome finishes. The materials, equipment and expertise required makes professional chroming the best option for critical applications like classic car restorations.

Frequently Asked Questions

Is it illegal to chrome plate at home?

While it’s not illegal per se, the chemicals used in chrome plating are highly hazardous and regulated for environmental reasons. There are significant risks involved with DIY plating.

What metals can be chromed at home?

Steel, iron, nickel alloys, copper, and pot metal like zinc can be chromed with home kits. Precious metals like silver or gold are difficult.

How thick of a layer does home chrome plating apply?

DIY cold chrome plating will deposit around .2 mil thickness. Professional plating can apply layers over 1 mil thick for much greater durability.

How smooth does the metal need to be for chroming?

Some minor pitting and roughness can be covered by the chrome layer, but starting with smoother surfaces produces better results.

How long does home chrome plating last?

With proper prep and sealing, a DIY chrome finish can last 1-3 years with moderate use. Professional chrome lasts 10-15 years or more.

Applying a chrome finish at home takes some effort but can create brilliant results when done properly. With the right techniques and safety measures, chrome plating kits allow hobbyists to get attractive, durable chrome coatings without paying professional shop rates. Or for critical applications like car restoration, hire experienced platers to ensure a flawless factory-quality finish.
