Supreme Surface was first established as a tile and stone company and operated a service department for over 20 years. During that time, we developed a process that restored the look of granite sinks. We participated in thousands of sink fabrications, restorations, installations, and repairs. Even in cases where individuals have sandpapered their entire sink, this almost always created the desired result. Over the past several years, our Help Line has walked individuals like you through this process over the phone, and now we have compiled the information into this simple how-to blog for your convenience.
We understand that many individuals may have questions or concerns about the process. If the desired outcome was not reached, or if any questions/concerns arise, we urge you to call our Help Line at 317-865-0000, and one of our stone-care pros will help find a solution.
To restore a granite sink, we will need three separate products with three purposes and a few common accessories to help out.
- Supreme Surface® Scum & Mineral Deposit Remover
Why? Used to thoroughly deep clean the sink. The goal is to remove oil, mineral deposits, and soap scum from the surface without causing more damage.
- Miracle 511 Seal & Enhance 8oz
Why? It's used to enhance the color of the sink and reduce the rate of absorption. It must be 'Seal & Enhance'
- Supreme Surface® Granite Quartz & Marble Treatment
Why? Used to bond ioSeal to the surface before the first use and used for care and maintenance in the future.
- Accessories: new paintbrush, disposable bowl, and a solid white rag or towel.
- Search Phrase: Miracle 511 Seal and Enhance 8 oz.
- It's the smallest size available, and you'll only use it once!
- Usually available at Walmart. com or Amazon
Cathy K created a demonstration video to clarify the process. If you would like a visual demonstration of sink restoration (as well as an excellent before-and-after example), view the video below.
Make sure the sink is completely dry. Once the sink is dry, the first step is to safely deep clean the sink. We want to remove all mineral deposits, soap scum, or other pre-existing messes. Using the Scum & Mineral Deposit Remover, spray onto the surface, and let it sit for +/- 15 minutes. Keep the area moist, not allowing the product dry up. After 15 minutes, gently agitate the surface to remove deposits, thoroughly rinse, and dry.
We will want to ensure all messes or oils are removed, and the sink is thoroughly clean. If oils have been used in the past, applying this product may temporarily make the sink look worse. This is expected. Oils will generally leave a wet appearance, so removing them will temporarily leave the sink looking chalkier. We will solve this shortly. Repeat this step until the sink's appearance no longer changes after each application.
Only proceed to the next step once you are sure that re-applying the product will have no further effect. We want to ensure no remaining messes, mineral deposits, or oils.
Before you start:
Before proceeding to step 2, we recommend ventilating the area by running a fan or opening windows. The enhancer has a potent smell, so adequately ventilating the room will be your best friend.
Begin step 2 by grabbing your paintbrush, disposable bowl, solid white cloth/towel, and the Miracle 511 Seal and Enhance. Carefully pour some of the 511 Enhancer into your disposable bowl.
Ensure that the sink is dry, and begin using the paintbrush to apply the enhancer to your sink. You must apply the Seal and Enhance to the entire sink. Wait 4-6 minutes, and wipe the sink down with a solid white towel/cloth. It's important to note that you want a pure white towel/cloth since color might influence the sink's outcome. Be sure to wipe off any excess.
It will take between 4 and 6 hours for the sink to dry after one application and longer for each additional coat. After the first hour, visually inspect your sink and decide whether it would benefit from another application. If so, repeat step two. Remember that the more coats you use, the longer it will take to dry.
Note: Expect to apply between 2 and 5 applications
Step-3:Once the sink is thoroughly dried and before using, apply the Supreme Surface Granite Quartz & Marble Treatment with ioSeal. Spray the entire sink, wipe it dry, and your sink is ready.
With every use, the ioSeal in this product will bond to the surface. This reduces the ability for future mineral deposits to bond, making future water spots easier to clean. It also reduces the absorption and creates a smoother, more reflective surface. Follow the instructions on the back of the treatment, using the product once daily for 10-14 days, then at least once a week to maintain the treatment. This will allow ioSeal to accumulate and protect your surface to the best of its ability.
Future Care & Maintenance:
Supreme Surface combines everything you need to clean, shine and protect composite granite sinks into a simple-to-use Composite Granite sink Care and Maintenance Kit. Two of the three products used in the restoration video are included in the video and the steps listed above.
For the sake of preventing this from happening again, we have a couple of recommendations.
First, we want to ensure we do not accidentally damage the surface. Avoid using any harsh/acidic/alkaline-containing products on your sink. This means avoiding lemon juice, vinegar, bleach, window cleaner, oven cleaner, and most leading brands formulated to remove Calcium, Lime or Rust, ammonia, et cetera. You should also avoid using any abrasive or semi-abrasive or what is considered a non-scratch pad on your sink.
Second, we recommend using Supreme Surface Granite Quartz & Marble Treatment with ioSeal Treatment on a weekly basis to keep the surface properly clean and protected.
Thanks and happy cleaning,
