Rough Spots on Granite Countertops: How to Fix Them

How to Fix Rough Spots on a Granite Countertop

Granite countertops often get a lot of use, which is why we put so much thought and care into selecting them. From kitchen countertops where the entire family gathers to cook to bathrooms that are the host for a night of self-care, our granite countertops are the focal point of the home. So when rough spots on granite countertops show up, we notice immediately.

Wondering, “why is my granite countertop rough”? Granite slabs can become rough for several reasons, ranging from a low-quality stone selection to improper sealing or a lot of wear and tear. But that roughness doesn’t have to stick around. With the right tools and steps, you can fix your rough countertops for a smooth finish, and our experts at Granite Selection are here to tell you how.

Should Granite Countertops Be Smooth Anyway?

Should Granite Countertops Be Smooth

Granite is a natural material, so is it normal for granite to have rough spots anyways? Actually, in your home, it’s not. In many cases, when it comes to a countertop surface, granite is often smoothed to best integrate into the design of your home and offer an even, clean surface.

While some may select a more uneven stone to match their home’s unique aesthetic, more often than not, a smooth slab is used. This is for the purpose of functionality. Granite countertops, as we said, are often used in high-traffic areas. This means they frequently need to be wiped down to clean up any spills and dirt that can accumulate. If your surface is rough, uneven, or features chips and scratches, it can be harder to get really clean.

With this in mind, both designers and homeowners opt for smooth granite slabs to make the sealing and maintenance process easier for a clean, sanitary space.

How to Fix Rough Spots on a Granite Countertop

While cleaning recently, did you stop and think, “my granite countertop feels rough”? No worries, we know just how to fix it.

Tools and Materials You Need

Before you get going on smoothing your countertops, there are a few things you need to complete the process. The list includes:

  • Masking tape
  • A filler of choice (this may be Epoxy resin, viscous superglue, or another filler you prefer).
  • Ammonia-based cleaner
  • 300+ grit paper
  • Razor or x-acto knife

Now you have the tools, it’s time to go through the steps!

Step 1: Clean the Rough and Chipped Spots

Cleaning Spots on Granite

One of the main downsides to rough spots on granite countertops, beyond the appearance, is that they will accumulate bacteria. For this reason, it’s important to start by cleaning the area with an ammonia-based cleaner and then ensure it’s dry before moving onto the next step.

Step 2: Surround the Damaged Area with Masking Tape

To ensure that the filler you’re using doesn’t affect the rest of the countertops, use masking tape to surround the rough, damaged area. This will contain the workspace to just the areas that need fixing.

Step 3: Apply Filler

Now that the area is prepped and ready to go, it’s time to pour filler into any holes, chips, cracks, and rough spots. Be sure not to overfill – we want a smooth, even surface!

Step 4: Let Dry

Now that you’ve used filler, you’ll need to let the surface dry for at least 24 hours. Once it is dry, you can remove the masking tape and any extra filler that may remain on the sides. To smooth away the remaining filler, use a razor or x-acto knife.

Step 5: Polish!

Polishing Granite Countertop

Wondering, “how do I polish a granite countertop?” It’s pretty simple! To get your surface smooth and flawless, polish it off with grit paper. Once you’re done, clean the surface.

The materials you choose for your smoothing process can vary based on the granite countertop you have. In many cases, as long as you are sure to clean it first, this method will seal and hold for a smoother finish.

Should I Replace or Refinish My Granite Countertop?

Replace or Refinish My Granite Countertop

A slab may be irreparable in some cases, and simply knowing how to apply granite sealer won’t be enough. A stone is considered “irreparable” when it’s covered in these rough spots, chips, or scratches that have significantly diminished the quality. So, what do we do then? Replace it.

Granite is a highly popular countertop choice as it is incredibly strong – withstanding heat and everyday use for long-term durability. But after years of wear and tear, it can start to show its age. Between the 10 and 15 year mark and after a few repairs, it’s likely time to simply replace your stone. While this does come at a price, it’s worth it as attempting to put multiple bandaids on the dings and scratches can add up over the years.

Not sure if you should just re-seal or fully replace your countertops? If you’ve already tried refilling the rough spots and chips and there are still uneven areas and gaps left, it’s time to replace your stone. This is important to do to avoid a buildup of bacteria and mold – something we absolutely want to avoid, especially in our kitchen!

If your countertops don’t need to be fully replaced quite yet, refinishing them is key to warding off further damage in the years to come.

In the process of fixing and resealing your countertops, dirt and bacteria can build up, making it even more important that you keep your surface super clean. These high-traffic areas are sure to get dirty, especially after a night of cooking, but leaving them unwashed can cause even more damage in the long run.

To ensure your countertops remain strong, we recommend deep seasonal cleanings. Additionally, ensure that you reseal your stone every two to three years. Having professional work on your surface’s resealing will ensure it’s done with expertise, helping the repair last longer and further avoiding a full counter replacement.
