How To Refinish Old Bathroom Sink

How to Refinish Old Bathroom Sinks

A worn-out bathroom sink can detract from the overall aesthetic of your bathroom. Instead of replacing the entire fixture, consider refinishing it. Refinishing can restore the shine and hide scratches, chips, and stains, giving your sink a fresh new look. This process is generally less expensive than replacing the sink and can be a rewarding DIY project for homeowners with basic skills.

Preparing the Sink for Refinishing

Before you start refinishing, it's essential to prepare the sink properly. This involves removing any existing coatings, cleaning the surface, and masking off areas that you don't want to refinish.

Remove Existing Coatings:

The first step is to remove any existing coatings, such as paint, enamel, or sealant. You can use a chemical stripper or a scraper to accomplish this. If using a chemical stripper, protect your skin and eyes with gloves and goggles. Follow the instructions on the product label thoroughly.

Clean the Surface:

Once you've removed the old coatings, clean the sink surface thoroughly. Use a mild detergent and a scrub brush to remove dirt, grime, and any remaining residue. Rinse the sink well with water.

Mask Areas:

Use painter's tape to mask off areas that you don't want to refinish, such as the faucet, handles, and drain assembly. Cover any surrounding surfaces with drop cloths to prevent accidental drips.

Choosing the Right Refinishing Products

There are several types of refinishing products available, each with its own advantages and disadvantages. Consider the following options:

Epoxy-Based Coatings:

Epoxy coatings are durable and resistant to stains, scratches, and chemicals. They are also relatively easy to apply. However, they can be difficult to remove if you need to refinish the sink again in the future.

Acrylic-Based Coatings:

Acrylic coatings are more flexible than epoxy coatings and are better suited for sinks with curved surfaces. They are also easier to clean up. However, acrylic coatings are not as scratch-resistant as epoxy coatings.

Porcelain Repair Kits:

If your sink has chips or cracks, you can use a porcelain repair kit to fill in the damaged areas. These kits typically contain a special paste that you apply to the damaged area and then smooth out. Once the paste dries, it hardens to create a durable repair.

Applying the Finish

Once you have chosen the refinishing product, follow the manufacturer's instructions for application. Typically, you will need to apply the product in thin, even coats. Allow each coat to dry completely before applying the next.

Apply the First Coat:

Begin by carefully applying the first coat of refinishing product. Use a brush, roller, or spray gun, depending on the product and your preference. Work in small sections and apply the product evenly.

Smooth out the Finish:

After applying the first coat, allow it to dry completely. Once dry, use a fine-grit sandpaper to smooth out any imperfections.

Apply Additional Coats:

Apply additional coats of refinishing product as needed, following the manufacturer's instructions. Allow each coat to dry completely before applying the next.

Remove Masking Tape:

Once the final coat has dried, remove the masking tape carefully to reveal the finished sink.

Finishing Touches

After the refinishing product has cured completely, you can apply a sealant to protect the finish and enhance its durability. Some refinishing products already contain a sealant, so check the manufacturer's instructions.
