Clean the sink thoroughly
To repair an acrylic kitchen sink, it is important to clean the sink thoroughly before beginning any repair work. This is because dirt or dust on the sink’s surface will prevent the repair materials from adhering properly, and make it harder to distinguish the scratch or nick from the surrounding area.
First, clean the sink with a household cleaner. Ensure that you use a product that is suitable for acrylic sinks. For example, you could use Windex or 409. If there are stubborn stains, you can use Bar Keepers Friend, but be sure to remove all soap residue afterward. Make sure the sink is completely dry before proceeding with any repairs.
If you are repairing a scratch or nick, you will need to smooth out the edges. To do this, wet a piece of fine-grit sandpaper and lightly sand the area. Ensure that the paper remains wet throughout this process, remoistening if necessary. Sand in a circular motion over and around the scratch.
Finally, wipe acetone over the scratch or chip to ensure it is free of any oils or residue from the sanding process. This will ensure that the repair materials can properly adhere to the sink’s surface.

Sand the damaged area
Sanding the damaged area is an important step in repairing an acrylic kitchen sink. It helps create a smooth surface for the repair materials to adhere to and can also help to remove any scratches or nicks. Here is a step-by-step guide to sanding the damaged area:
- Clean the sink thoroughly: Before sanding, ensure that the sink is free of any dirt, dust, or soap residue. You can use a household cleaner or, for stubborn stains, a product specifically designed for acrylic sinks, such as Bar Keepers Friend. Make sure to dry the area afterward.
- Choose the right sandpaper: For sanding acrylic sinks, it is recommended to use fine-grit wet/dry sandpaper. The grit refers to the abrasiveness of the sandpaper, and for this project, you should look for sandpaper with a grit of 1000 or 220, followed by a finer grit of 400.
- Soak the sandpaper: Before use, soak the sandpaper in a bowl of tap water for about five minutes. This will help to prevent the sandpaper from scratching the surface of the acrylic.
- Sand the damaged area: Once the sandpaper is wet, lightly sand the scratched area in circular motions. Always keep the sandpaper wet and re-moisten if necessary. Focus on sanding the scratch or nick, rather than trying to sand out the damage completely. The goal is to create a smooth surface for the repair materials to adhere to.
- Wear protection: Sanding can create dust and particles that you don’t want to inhale. It is recommended to wear a particle mask to protect yourself during this step.
- Buff the area: After sanding, use a fine-grade Scotch-Brite pad or a soft cloth to buff the area. This will help to smooth out any remaining rough patches and create a uniform surface.
Remember, when sanding acrylic, it is important to be gentle and not apply too much pressure. Always keep the sandpaper wet and work in circular motions to avoid further damaging the sink.

Use an acrylic repair kit
Using an acrylic repair kit is a common and effective way to repair your acrylic kitchen sink. These kits are widely available and easy to use. Before you begin, ensure you are working in a well-ventilated area and are wearing a particle mask to avoid inhaling any dust or fumes.
First, clean the sink thoroughly. Use a household cleaner to ensure the surface is free of dirt, dust, and soap residue. You can use a product like Bar Keepers Friend to tackle stubborn stains. Then, use a piece of wet/dry fine grit sandpaper to smooth out the edges of the scratch or nick. Remember, you are not trying to sand out the damage, but to create a surface for the repair materials to adhere to.
Next, wipe acetone over the area to remove any oils and particulates from the sanding. Then, it’s time to mix the filler and catalyst from the repair kit together. Most kits will include these two separate ingredients. When mixed, the catalyst will begin to harden the filler, but the process is gradual, giving you time to work.
Apply the mixture to the damaged area, overfilling slightly to ensure the filler covers it completely. This will help the repaired area blend in. Allow the filler to dry, which can take 10 minutes to an hour or more. You can speed up this process with a hairdryer.
Finally, buff the repair with wet sandpaper to smooth out any rough patches and sculpt the filler to the shape of the sink. Finish by buffing the area with a soft cloth to polish and blend the repair.

Buff the repair with sandpaper
Before buffing your acrylic kitchen sink with sandpaper, it is important to understand the basics of the repair process. There are many acrylic repair kits available on the market, and they all work on similar principles. For the repair to look its best, a colour match is very important. Choose a kit that will allow you to achieve the same colour as your sink, or at least come very close. Be sure to follow the safety precautions outlined in the kit’s instructions.
Once you have selected the appropriate repair kit, you can begin the repair process. Start by thoroughly cleaning the sink to ensure that dirt or dust on the surface does not prevent the repair materials from adhering. The sink should be completely clean to the touch, not just visibly clean.
Now you are ready to buff the repair with sandpaper. Wet a piece of fine-grit sandpaper and lightly sand the scratched area, always making sure the paper is wet. Sand in circles over and around the scratch. Remember, you are not trying to sand out the damage, but rather create a surface to which the repair materials can adhere. Re-moisten the sandpaper as needed.
After sanding, wipe acetone over the scratch or chip to ensure it is free of oils and particulates from the sanding process. Then, proceed with the repair kit instructions, mixing the filler and catalyst according to the kit’s directions. Apply the mixture to the damaged area, overfilling slightly to ensure complete coverage. Allow the filler to dry, and then buff the repair with wet sandpaper to smooth out any rough patches and sculpt the filler to the shape of the sink. Finish by buffing the area with a soft cloth to polish and blend the repaired area with the surrounding sink surface.

Polish the sink
Polishing an acrylic sink is a great way to repair scratches, chips, and nicks. Here are the steps you can follow to achieve a polished and repaired acrylic sink:
Firstly, clean the sink thoroughly. Use a household cleaner to ensure the sink is not only visibly clean but also clean to the touch. Remove any soap residue and dry the area. If there are stubborn stains, you can use Bar Keepers Friend, but be sure to dry the area afterward.
Next, prepare the sandpaper. Place a section of 1000-grit wet/dry sandpaper in a bowl of tap water for about five minutes. You can also use 220-grit abrasive sandpaper, followed by 400-grit paper. Once the sandpaper is ready, lightly sand the scratched area, always keeping the paper wet. Sand in circles over and around the scratch. Remember, you are not trying to sand out the damage but to create a surface to which repair materials can adhere.
After sanding, wipe acetone over the area to ensure it is free of oils and particulates from the sanding process. Then, it is time to apply the filler. Most acrylic repair kits have a filler and a catalyst that hardens the filler when mixed. Before applying the filler, add a toner (if using) to match the color of the sink. Then, add the catalyst to the filler and mix thoroughly according to the kit’s directions.
Apply the filler mixture to the damaged area, overfilling slightly to ensure complete coverage. Allow the filler to dry, which can take 10 minutes to an hour or more. You can speed up the drying process with a hairdryer.
Once the filler is dry, it is time to polish the sink. Buff the repair with wet sandpaper to smooth out any rough patches and sculpt the filler to the shape of the sink. Finally, buff the area with a soft cloth to polish and finish the blending, leaving your sink polished and repaired.
While the above steps provide a general guide, it is important to follow the specific instructions of your chosen repair kit and always work in a well-ventilated area when using epoxy fillers. Additionally, consider seeking professional help if you are uncomfortable with the process or if the damage is extensive.
