Granite is a popular choice for kitchen countertops due to its durability and aesthetic appeal. However, over time, granite countertops may start to lose their shine and develop small scratches or stains.
Homeowners often wonder if they can apply a clear coat on granite to restore its original beauty and protect it from further damage. In this blog post, I will explore the topic of applying a clear coat on granite countertops and provide helpful insights for those considering this option.
Can You Put Clear Coat on Granite?
Yes, you can apply a clear coat on granite countertops to restore its original beauty and also protect it from damage. With a moderate amount of mixed product, apply the clear coat to achieve a smooth texture, simulating the granite surface
It’s also important to note that it’s not necessary to apply a clear coat on new granite. Granite is a natural stone that already has its own protective sealant applied during the fabrication process. Adding a clear coat on top of this sealant may not only undermine its effectiveness but also result in an unnatural-looking finish.
Types of Clear Coats You Can Put on Granite
There are different types of clear coats available on the market, each with its own unique properties. Here are some common types:
1. Water-based clear coats
These clear coats are easy to apply and clean up, as they are water-soluble. They do not emit strong odors and are considered environmentally friendly. However, water-based clear coats may not provide as strong of a protective layer as other types.
2. Solvent-based clear coats
Solvent-based clear coats contain volatile organic compounds (VOCs) and require proper ventilation during application. They provide a more durable and moisture-resistant finish compared to water-based clear coats. However, they can emit strong odors and may not be suitable for those with respiratory sensitivities.
3. UV-cured clear coats
UV-cured clear coats are applied as a liquid and then cured with ultraviolet light. This type of clear coat offers excellent durability and scratch resistance. However, it is usually applied by professionals and may not be readily available for DIY projects.
Best Clear Coat to Use on Granite Countertops
I would suggest using Giani Countertop Paint Clear Acrylic High-Gloss Topcoat. This topcoat is specifically designed for use on granite countertops and provides a glossy finish. However, it is important to note that the manufacturer recommends using it on surfaces other than natural stone.
How to Apply Clear Coat on Granite
If you still decide to apply a clear coat on your granite countertops, here is a general guide on how to do it:
Materials Needed
- Clear coat of your choice
- Microfiber cloth
- Paintbrush or foam brush
Step 1: Lightly shake the bottle of Clear Coat
Start by lightly shaking the bottle of clear coat to ensure that it is well mixed and ready for application.
Step 2: Apply the coat with a microfiber cloth
Using a microfiber cloth, apply a thin, even layer of the clear coat onto the granite surface. Work in small sections to ensure proper coverage.
Step 3: Apply another heavy application
After 3-5 minutes of the first application, apply another heavier coat of the clear coat. This will help ensure that the surface is properly sealed and protected.
Step 4: Wipe off excess sealer
After approximately 30 minutes, wipe off any excess sealer that has not been absorbed into the granite using a clean microfiber cloth.
Step 5: Keep the surface dry
Allow the surface to dry completely for 24 hours after the application. Avoid placing any objects or liquids on the countertop during this time.
Step 6: Perform a water test
After 24 hours, you can perform a water test to check the effectiveness of the clear coat. Simply sprinkle some water onto the countertop and observe if it beads up or absorbs into the surface. If the water beads up and does not penetrate the granite, the clear coat has been successful.
Maintenance and Care of Clear-Coated Granite
If you have chosen to apply a clear coat on your granite countertops, it is important to understand how to maintain and care for them properly. I will share some essential tips for maintaining and caring for clear-coated granite countertops to ensure their longevity and appearance:
1. Regular cleaning
Avoid using harsh or abrasive cleaners that can damage the clear coat. Instead, opt for pH-neutral cleaners specifically designed for use on granite countertops. These cleaners are gentle and effective in removing dirt, stains, and spills without causing any harm.
Acidic substances such as lemon juice, vinegar, or abrasive cleaners can etch or dull the clear coat over time. Be mindful of the products you use and avoid any that can harm the clear coat.
Accidents happen, and spills are inevitable in the kitchen. However, it is important to clean up spills promptly to prevent any potential staining or damage to the clear coat. Blot spills with a clean cloth or paper towel, and gently clean the area with a pH-neutral cleaner.
2. Avoiding heat and impact
To protect the clear coat from heat damage, always use trivets or hot pads when placing hot pots, pans, or dishes on the countertop. Direct contact with high heat can potentially cause the clear coat to discolor, bubble, or peel.
Clear-coated granite is durable but can still be susceptible to impact damage. Avoid dropping heavy objects or applying excessive force on the countertop surface to prevent scratches, cracks, or chips in the clear coat.
3. Regular maintenance
Over time, the clear coat on granite countertops may wear away due to regular use and cleaning. If you notice that the clear coat is no longer providing the protection it once did, it may be time to reapply a fresh coat. Follow the instructions provided by the manufacturer or consult with a professional for the best results.
While the main surface of the granite countertop is clear-coated, the edges may be exposed. It is important to seal the edges using a silicone sealant to provide additional protection and prevent moisture from seeping into the stone.
Conclusion
Yes, you can put a clear coat on granite surfaces. While it’s indeed possible, this process should be approached with care and consideration. Clear coating your granite countertops or other granite surfaces can offer several benefits, such as enhancing its shine, protecting it from stains, and prolonging their lifespan.
However, it’s essential to understand that not all clear coats are suitable for granite, and the process requires proper preparation, application, and maintenance.
