As a bar sink supplier, I often encounter customers with questions about maintaining and reviving their old bar sinks. One of the most common queries is whether it's possible to refinish an old bar sink. In this blog post, I'll explore this topic in detail, discussing the feasibility, methods, and considerations of refinishing a bar sink.
Understanding the Feasibility of Refinishing
The first question to ask is whether refinishing an old bar sink is a viable option. The answer largely depends on the material of the sink, its current condition, and the extent of damage.
Sink Materials and Refinishing Potential
- Stainless Steel: Stainless steel sinks are a popular choice for bars due to their durability and resistance to corrosion. Refinishing a stainless steel sink is relatively straightforward. Minor scratches can be buffed out using fine-grit sandpaper or a stainless steel cleaner. For more significant damage, such as deep scratches or dents, a professional refinishing service might be required. However, with the right tools and techniques, it's possible to achieve a satisfactory result at home.
- Porcelain or Enamel: Porcelain or enamel-coated sinks can also be refinished, but the process is more complex. These sinks are prone to chipping and cracking, which can expose the underlying metal and lead to rust. Refinishing a porcelain or enamel sink typically involves applying a new layer of enamel or a specialized refinishing kit. It's important to note that the success of the refinishing depends on the quality of the original coating and the extent of the damage.
- Composite or Stone: Composite and stone sinks, such as granite or quartz, are known for their durability and aesthetic appeal. Refinishing these types of sinks can be challenging, as they require specialized equipment and materials. Minor scratches can sometimes be buffed out, but deeper damage may require professional restoration.
Assessing the Condition of the Sink
Before deciding to refinish an old bar sink, it's essential to assess its current condition. Look for signs of damage, such as cracks, chips, scratches, or discoloration. If the damage is extensive, refinishing may not be a practical solution, and it might be more cost-effective to replace the sink. Additionally, consider the age of the sink and its overall structural integrity. An older sink may have underlying issues that could affect the longevity of the refinishing job.
Methods of Refinishing a Bar Sink
Once you've determined that refinishing is a viable option, the next step is to choose the appropriate method. Here are some common methods for refinishing different types of bar sinks:
DIY Refinishing
- Stainless Steel: For minor scratches and surface blemishes on a stainless steel sink, you can use a fine-grit sandpaper or a stainless steel cleaner to buff out the marks. Start by cleaning the sink thoroughly with a mild detergent and warm water. Then, apply the sandpaper or cleaner in a circular motion, following the grain of the stainless steel. Rinse the sink with water and dry it with a soft cloth.
- Porcelain or Enamel: Refinishing a porcelain or enamel sink requires a specialized refinishing kit, which typically includes a primer, a topcoat, and a catalyst. Before applying the refinishing kit, clean the sink thoroughly and sand the surface to create a rough texture for better adhesion. Follow the instructions provided with the kit carefully, applying the primer and topcoat in thin, even layers. Allow the sink to dry completely between coats, and avoid using the sink for at least 24 hours after the final coat.
- Composite or Stone: Minor scratches on composite or stone sinks can sometimes be buffed out using a fine-grit sandpaper or a polishing compound. Start by cleaning the sink and applying the sandpaper or compound in a circular motion. Rinse the sink with water and dry it with a soft cloth. For deeper scratches or damage, it's recommended to consult a professional stone restoration service.
Professional Refinishing
If you're not comfortable refinishing the sink yourself or if the damage is extensive, it's advisable to hire a professional refinishing service. Professional refinishers have the expertise, equipment, and materials necessary to achieve a high-quality result. They can also provide a warranty for their work, giving you peace of mind.
Considerations Before Refinishing
Before refinishing an old bar sink, there are several factors to consider:
Cost
Refinishing a bar sink can be a cost-effective alternative to replacing it, but the cost can vary depending on the method, the extent of the damage, and the type of sink. DIY refinishing kits are generally more affordable, but they may require some skill and time to apply. Professional refinishing services can be more expensive, but they offer a higher level of quality and assurance.


Time
Refinishing a bar sink is not a quick process, especially if you're doing it yourself. It can take several hours or even days to complete, depending on the method and the number of coats required. Additionally, you'll need to allow the sink to dry and cure properly before using it again.
Durability
The durability of the refinishing job depends on several factors, including the quality of the materials used, the application method, and the type of sink. While refinishing can restore the appearance of an old bar sink, it may not be as durable as a new sink. It's important to follow the manufacturer's instructions for care and maintenance to ensure the longevity of the refinishing.
Aesthetic Appeal
Refinishing a bar sink can improve its appearance, but it may not match the exact color or finish of a new sink. If you're looking for a perfect match, it might be better to replace the sink. However, if you're willing to accept a slightly different look, refinishing can be a great way to give your old bar sink a new lease on life.
