How to Repair Cracks in Granite Countertops

Granite Scissure Repair Advice & Solutions

QUESTION:

We only recently had two cm Santa Cecilia granite countertops installed.

We establish a crack in the granite in the corner. The crack goes from one wall of the corner to the other.

Not too noticeable, only we are concerned nearly whatsoever additional problems it might cause.

My husband too realized that there is no plywood support underneath the countertops, which really raises more concern for the states at this point.

Could the lack of plywood support be the reason for this crack and should we insist that they come dorsum and reinstall with plywood?

ANSWER:

Certainly you should have the installers return to appraise the damage and, if needed, mend the granite crack. Although, your installer may not be the all-time one for the job.

There are two types of granite cracks:

Hairline cracks typically cannot be seen or even felt easily, do not have a lip, and no gap or separation of the cleft.

A hairline scissure can occur during install as the extremely heavy and rigid slab is moved into place. Typically, such cracks happen effectually sinks or other cutouts with thin sections of granite.

Naturally, many homeowners want the cracked slab replaced. But it can happen even with the most conscientious install and in that location's no guarantee information technology won't happen with the replacement slab.

Hairline cracks generally do not need repair, volition not get worse, and do non touch the apply, cleaning, or integrity of the countertop. In some cases, additional back up in the area could be beneficial.

Separated cracks have a gap, are hands seen and felt, and have a lip.

Separated cracks happen from a heavy impact, standing on the granite countertop, or foundation movement and require repair.

Granite Crack Repair Options

An experienced granite repair specialist is preferred for cracks in granite, marble or whatsoever natural stone.

The typical granite installer is not experienced enough to artfully repair a crack in granite. You'll terminate up with an ugly scar filled with epoxy. Installers can do minor repairs, just granite scissure repair is a major repair (with a separated crevice).

A person who has made crack repairs before knows the products and methods required and won't be experimenting or learning as they get.

Cracks in granite are repaired first past filling with an acrylic or using a color-matched epoxy to gum the pieces dorsum together. The selection here depends on the nature and severity of the crack.

Either manner the fissure volition remain easily visible and palpable unless the surface is then re-polished.

Filling or gluing the crack together could be a DIY job or something your installer could do, all the same, re-finishing the surface definitely is not a DIY project.

Polishing granite cracks to remove the edges of the crack and knowing how to blend the fissure itself with the surrounding surface colour and polish requires feel, cognition and skill.

This is why you desire an experienced granite counter repair pro. Virtually fabricators / installers focus on installing and not repairing.

Luckily, since it's in the corner, even a mediocre repair won't be very noticeable and isn't a structural result.

Doing aught is also an option. When the crack in a granite countertop is only a short, hairline crack it rarely presents any real problems or gets worse. If it does, so you have it repaired.

It may not be worth the expense and hassle

to repair a unmarried, curt or surface hairline scissure even effectually a sink.

Modest cracks ordinarily don't pose whatever cleaning problems, and stains are rarely a problem, simply applying a little actress sealer over a scissure isn't a bad idea.

Long or total-thickness cracks and/or areas with multiple cracks likely need repair.

Granite Scissure vs. Cleft

Any word of cracks in granite countertops must also include an explanation of fissures.

Fissures are lines formed in the design of the stone past the borders of diverse crystalline groups inside the stone.

Fissures can exist brusque or long... wide or narrow... just in the surface or full thickness... or may run through the countertop edges. Many granite countertop colors don't have any fissures, others just a few and some patterns have many running all over.

Fissures are similar to cracks. In fact, you could say a fissure is a naturally occurring "crack" and sometimes can fifty-fifty await nearly identical to a crack. The primal difference is separation.

• Fissures maintain structural integrity of the stone. No separation or space exists. It'south a cleft that hasn't really cracked or split.
  
• Fissures occur across the slab... not just in one or two spots.
  
• Fissures are level, experience smoothen and do not take an edge.
  
• Fissures are typically curved and do not run in direct lines or have angular zig-zags, but sometimes await like cracks.

Fissures are weak points and can become a "crack" from impact or stressful forces during transportation, installation or after.

• Cracks are lines of physical separation. The stone has divide.
  
• Cracks have an edge you tin can feel or catch with a fingernail.
  
• Cracks in granite are most commonly "hairline", just can be wider.
  
• Cracks can be short, long, surface or total-thickness of the slab.
  
• Cracks typically occur at sink and cooktop cutouts, edges and corners.

Plywood Support for Granite Countertops

Well-nigh/all granite slab countertops are installed right onto the cabinets without a plywood substrate. This is normal and provides plenty of back up.

A tile countertop would need the plywood or backer lath underlayment, simply it's unnecessary for a slab countertop. Of course, you should non stand on granite countertops and exist mindful to follow granite care guidelines.

I don't think the supposed "lack" of support had annihilation to practice with the cracked granite.

A plywood substrate is sometimes used to create a level surface when cabinets/floors are non level. Or to elevate the kitchen countertop when a laminated edge is used, which helps keep the border from interfering with the drawers.

The cracked corner probably occurred during moving and installing the granite counter top slab. Slabs are big, heavy and hard to move... can get some accidents. Aye, I know you lot didn't pay for a croaky corner, just is it actually worth the hassle to replace?

If it was an edge or in an plainly visible area, then it may have to be redone. Simply information technology can likely exist repaired reasonably well, and if in a dorsum corner, you simply won't notice it that much (if at all). Peradventure y'all can put some appliance or other decoration at that place also.

Contact your installer or a granite repair specialist and see what is needed to fix the cracked corner. Just yous may make up one's mind just to leave information technology. If it's a hairline crack with minimal lip, it likely won't become worse or cause any hereafter problem.

Granite Countertop Crack at Sink Corner

by Barbara
(Portland, OR)

Uba Tuba Granite Crevice

QUESTION:

Uba Tuba granite countertop. The top is 11 months, iii weeks old.

There is a crack at the corner of the sink.

I don't know how it happened...no one has confessed to causing information technology. Should this be covered by the warranty?

Could this have been acquired by the undermount sink non existence installed correctly?

Answer:

Cut outs for sinks and cooktops are weak points and the most likely spots for cracks in granite to occur.

The sink area receives a lot of abuse. A crack could develop from direct impact, someone sitting or standing on the countertop, or stress from using the sink.

Yeah... it also could have happened during installation of the granite countertop.

Ordinarily this happens simply because a granite slab is extremely heavy and difficult to maneuver. Despite all best efforts and care sometimes a cleft develops in weaker areas.

If a major crack occurs during install whatsoever reputable fabricator will, repair the scissure, cut out and replace the surface area if possible or only swallow the cost and start over.

But if just a hairline cleft it may go unnoticed or even when noticed installed anyhow because these are almost never a problem, volition remain stable and do not affect the performance of the counter superlative.

Highly unlikely it developed because the sink was installed "incorrectly". Not much to screw upwards with that.

Nevertheless, 11 months after install it'due south impossible to tell if the installers are somehow to blame, so not really fair or productive to accuse them at this point.

And information technology may be nothing to worry near. If the crack can merely be felt past running your finger tip or fingernail over it and there isn't whatsoever lip, then it probably won't be an issue.

Still, if the cleft has a lip and/or it looks to become all the way through the entire slab, then yous may take an issue and it could get worse, especially effectually the sink.

Cracks in granite countertops effectually the sink most frequently are just hairline cracks without a lip and never really present a problem other than a bit of frustration that it exists.

Possibly a uncomplicated repair or extra support could be added to stabilize the surface area. Check with your installer.

Of grade, yous tin't expect them to do this for free since there's no way at this signal to fault them for it.

If there is a lip, y'all may still be able to level the surface, repair and stabilize the area to eliminate any problem. This will crave professional granite repair of form.

Worst case scenario is replacement of a office or the unabridged granite counter top, but well-nigh never needed.

Hairline Cracks in New Granite

past Donna
(Philadelphia)

QUESTION:

We accept just installed new granite countertop.

The cutout for the stove top was likewise pocket-size, but the installer shoved the stove top into the space.

Now in that location are hairline cracks radiating out from iii of the four corners of the melt meridian hole and the stove pinnacle is broken.

One of them goes all the way through the slab. The others seem to be on the surface.

Should we make them replace the granite countertop? They haven't fifty-fifty hooked up sink or stove pinnacle yet. They merits epoxy will solve the problem.

Reply:

I'd make them replace the granite. Considering they couldn't remember alee or be patient enough to practise the job right, I wouldn't trust any countertop repair task they were going to attempt.

A unmarried hairline crack somewhere, I wouldn't worry about, merely multiple cracks radiating from 3 corners of the cook top cutting-out... no good.

Y'all will exist constantly stressing this expanse also with additional weight and pots and pans banging around (if you cook like me anyhow!).

Plus, with so many cracks concentrated in small areas, they may get worse with more becoming full thickness.

True, epoxy or polyester resin could repair the croaky granite and improve the integrity in the area, but cutting-outs are weak areas.

Even with repair and any back up that they may be able to add the entire area is compromised.

Epoxy can exist very strong and a stellar repair may be sufficient, but I'd want a granite repair specialist to do information technology.

Now, I don't know how long or how many cracks there are, and so peradventure it sounds worse than it is and you're thinking mayhap but to negotiate a much cheaper price and an adequate repair.

That's an option...

However, there is all the same the event of the broken cook top.

You need a new one... the same one won't fit this cutting out. And then, yous need one that volition fit this cut out because enlarging the cutting out at present is risky... could wreck the slab.

Maybe you get lucky and detect i, but this is a bassackwards mode of doing information technology.

I say start over.
