Before we talk repairs, let’s talk about prevention

While stuff happens, here are a few things you can do to prevent cracks and damage to your granite countertop.

#1. Remember to seal the surface every year.

Granite is a porous stone. It requires an annual seal to ensure its long-term durability. If you do not seal it at least once every year or two, bacteria seeps into the stone. That makes it unhealthy for you.

Also, it could weaken the stone when water and other liquids get into the porous rock.

#2. Regular Maintenance

Many of the cleaning products consumers use to damage the seal over time, it is essential to know which cleaners to use.

Daily cleanings of your granite counter require just hot water. You can then use special granite cleaner when you do weekly and monthly cleanings of your granite countertop.

Etch Marks

Often granite countertops get etch marks. Larger ones might require a professional. However, homeowners can usually fix smaller marks left by a lemon or tomato.

Start by cleaning the affected area. You can use a little stone soap, but the majority will be water. It should wipe away the dirt and scum. Then dry the area thoroughly.

Next, apply granite polishing powder to the area and buffer it with a variable speed electric drill on a low-speed setting. Keep the granite powder on the stone as you buff it, and then clean it off afterward.

Refinishing and Resurfacing

Often if you do not clean your granite countertops correctly, over time the stone dulls. You might need to polish the granite using a countertop polish or even refinish the countertop.

To be clear, the shine on the stone comes from the finish. If the polish does not work, then you might need to resurface your granite countertop. Stone restoration professionals can help you if polishing does not work.

How to repair cracked granite countertop

Hairline Cracks

Hairline cracks happen naturally in the granite countertops. They are tiny, almost invisible cracks that do not affect the cleaning, use, or quality of your counter.

Separated Cracks

Separated cracks, on the other hand, are visible. They can get worse if you do nothing. Often you can repair a separated crack in granite countertop by filling in the gaps with an epoxy glue that matches the color of the stone.

Some granite professionals even use some of the granite dust from where the break occurs to color the epoxy glue.

If you do it yourself, then make sure you clean the area before applying the glue.

Also, put masking tape around the area to ensure you do not apply glue to the surrounding granite.

Once you glued the separated crack, re-polish the surface to get the area to match the rest of the counter. Often this requires a pro to polish the stone fine enough for guests to not see the crack.
