Spray chrome it is not a regular paint and it takes some practice at the beginning to properly understand how to achieve perfect results. When our customers first start using Cosmichrome they may have some imperfections in their final results, and at times some simple adjustments can make a big difference. Given the years of experience using the spray chrome technology we’ve made a list of 15 Golden Rules that every applicator needs to make sure they are following to achieve the superior results with Cosmichrome. We will disclose these 15 rules in 3 posts on our website over the course of the next months. Here are the first 5 Golden Rules:
RULE 1 – KEEP YOUR BASECOAT DRY
- The drier the Cosmichrome Basecoat, the better.
- If air drying, allow Basecoat to dry for a minimum of 24hrs.
- Keep room at a temperature of 68ºF/20ºC.
- Larger objects require longer drying times.
- If baking, bake for a minimum of 1hr at 140ºF/60ºC
RULE 2 – PERFORM THE PLASMA TREATMENT RIGHT
- The Cosmichrome Basecoat must be completely dry before performing any plasma treatment.
- Move quickly and steadily throughout the entire part!
- Passing the torch slowly can result in burning and bubbling of the Basecoat.
- Properly plasma treated Basecoat will easily wet with water.
- Plasma treatment done incorrectly may not deposit well in some areas.
- Improper plasma treatment will repel water like a waxed surface.
- When this occurs, you need to plasma treat the area again before applying the A22 activator.

RULE 3 – USE NON-ABSORBING MASKING TAPES
- If the improper masking tape is used for plating, your part can be contaminated and ruined!
- VINYL TAPES Are water proof, flexible, easy to shape, will not bleed, are easy to peel off, and leave a clean surface line.
- PAPER TAPES Absorb liquids, tear often, wrinkle easily, are likely to bleed, are difficult to remove and leave residues behind.
RULE 4 – COVER ANY EXPOSED METALS
- Always be certain that all metal is carefully covered before working with your part. Other materials such as plastic or glass can be used without the need to cover with paint, as they will not react with the plating solutions and contaminate your part. However, any jigs that are made of metal must be sprayed with paint to protect it from interacting with the G4 & G5 plating solutions.
RULE 5 – KEEP YOUR ZONE CONTAMINANT FREE
- If your Basecoat is not clean, it is likely that some impurities, such as dust in the air have presented themselves on your part. Any impurities over the Basecoat surface will prevent the metal from depositing and will leave marks on the plating. To avoid this, it is recommended to have a well-insulated room with equal input and output of air flow, as well as to handle your Basecoated parts with clean new latex gloves every time.
- If you want to make sure that your part is clean or have touched your part with your fingers, use the Cosmichrome Basecoat Cleaner just prior to plating.
