As an environmentally-friendly solution to embellishing items with colour, powder coating produces excellent results. With the right finishing, it should come with long-lasting effects. However, if you do notice any chips or breaks in colour, there are ways to touch it up.
Don't use powder to address small areas
When the powder coating on your furniture suffers from a small blemish, don't use powder to recoat it. Without the galvanising tools that professionals rely on, you'll struggle to achieve a uniform finish. Instead, consider approaching a professional paint matching service for a liquid or aerosol alternative. While you may see some small differences when you look closely, it'll produce better cosmetic results, especially from a distance.
If you feel confident, use a sander
If you were the person to apply the powder, you may have some success in using it again. However, you should still avoid simply spraying more powder over the top. Instead, you'll need some sandpaper, paint thinner, and touch-up powder. Sand down the item in its entirety to remove any paint-resistant materials. Use paint thinner almost immediately to remove the debris and any oil that could affect your finish. After removing any remaining paint thinner, spray with the touch-up powder according to the instructions. Always remember to use paint thinner in an area with adequate ventilation.
For excellent results, try using zinc as a base
When touching up your powder coating, consider using zinc as a base. While it isn't essential, it will increase your chances of success. In addition to making the results of your touch-up smoother, the zinc will protect the item against corrosion. As a result, it's unlikely that you'll need to tackle any further issues.
If all else fails, try using a professional
If the powder coating is suffering from extensive damage, it's difficult to assess the situation without the right qualifications. For example, if there's a lot of rust, it's worth querying whether the metal beneath can hold a further coating. Similarly, if you're not familiar with the coating process, asking someone to repair a botched job can become expensive. Ask local suppliers if they can provide quotes and go from there.
While powder coatings deliver excellent finishes, they are sometimes difficult to repair. With the right finish, you're unlikely to encounter chips for years to come. Using the right techniques or a professional service, you can rest or your item to its former gloryShare
