Filling Granite Countertop Pits


QUESTION:

I have used a penetrating sealer on my granite countertop, but what can I use as a surface sealer to fill in all the pits in the granite?

ANSWER:

Most granite slabs won't have pits, although any slab of granite could develop a few pits over time. Typically not a big deal to fill these in.

You can do this granite countertop maintenance / repair yourself no problem.

Fill small pits and chips with the Granite & Marble Repair Kit for chips and pits.

Pros will use an epoxy or resin adhesive for granite repair of pits or a chip, but they can rarely get an exact color match. Thus, the repair is always visible.

The above product is a gel that is much easier to use than an epoxy filler where you must mix parts together.

You don't need a pro to do it and it dries level and clear allowing the natural granite color to show through so you can't even see the repair!

A granite that already has pits at installation is likely a bit prone to pitting, so you may have to perform this repair as regular maintenance.

Fortunately, this chip & pit granite repair kit blends the color and pattern perfectly (essentially invisible), so it will help maintain the beauty of the granite over time.

It works on all natural stone countertops and for a quartz countertop which can get pits too.

Pitting all over granite countertop
by: Matt V.

Five years ago we bought kitchen cabinets, granite kitchen countertops, and a granite island from a home remodeler and it was installed by their professionals.

The granites were nicely polished and 100% smooth with no pitting. We maintained it regularly.

There are no stains but the pitting is now getting bad.

We complained and the granite manufacturer sent a pro over and he filled the larger pits (1/4 inch) with epoxy and a torch. (He charged us $100 and said if we wanted it all done it would be well over $1,000!

His work came out fine but small pinholes are all over the island and larger pits are surfacing over the countertops.

He said it's because we were banging on the counter top which we weren't - The island serves as a table. No banging here! FYI, there are no kids.

I suspect the original polish they did is wearing off. There's one small top we don't use and it's perfect.

The installer says we're at fault.

The granite manufacturer said we didn't maintain it properly.

The home remodeler said it's not his fault. He never heard of anything like this... bull.

Very frustrating. What shall I do?

==== Countertop Specialty comment:

It's commonly known in the stone industry that granite can develop pits over time.

Granite is composed of many "grains" of various minerals and crystals. Over time with normal use that involves some physical impact and water exposure some of these minerals can pop out.

Granite countertop pitting will occur in the greatest concentration in the areas of greatest use.

Usually, that is around the sink. Some granite varieties or colors are worse than others.

The small pinhole pits are difficult to deal with. Not much can be done with these.

But the "normal" pits that are 1/16 to 1/4 inch in diameter can be easily filled using the Pit Repair Kits.

These use a clear acrylic gel that dries quickly and allows the natural color and pattern of the granite to show through so the repair is nearly invisible.

It can repair chipped granite as well so long as the chip is intact enough to glue back on.

I get that it is frustrating that the contractors, etc. are all passing the buck, but in fairness, this is not a "defect" of the granite. This is normal for granite.

It is not because the "polish is wearing off". There is nothing "on" the granite to wear off.

The polish is not something that is applied to the granite countertop. The polish is an integral part of the granite slab itself. The polish is created by grinding and smoothing the granite surface on huge machines.

The polish or shine is created the same way on any stone countertop.

The shine may get duller over the years as the smooth shiny layer of the finish can get worn away, but we're talking like 20 years (if then) and not five years.

Granite is so hard that wearing away the polished layer is rare.

Overuse of harsh chemicals or cleaners on your kitchen countertop could accelerate that wear, though.

Again, many granites do not pit or maybe only get 4 or 5 over many years, but some granites develop pits all over. Just need to fill them.

In severe cases, you could consider applying a countertop epoxy to the entire surface.

This type of epoxy is made specifically for covering an old or worn kitchen countertop.

You would then have an epoxy countertop and not a granite kitchen countertop, but it can look very cool with stylish and one-of-a-kind designs.

And no more pitting!
