Quartz countertop hairline crack
 

Anyone know who or how to fill a hairline crack in a quartz countertop? Left a hot air fryer on it and oops. Guess it wasn't very heat resistant......my bad

There are people who will take your money and apply a resin. But, in my opinion, the only options are to replace the countertop, or live with the crack.

Quartz or granite will crack with heat, and never stand on a countertop to replace a light bulb.

This may not help yourself, but if you ever get a a chip or imperfection in you Quartz this can be fixed easily with Super Glue (cyanoacrylate glue). Clean the imperfection so it is free of loose debris. Then fill the imperfection with "super glue." Once thoroughly dry, take a sharp item (i.e. razor blade) and with a swift motion, cut off any portion of the glue that resides above the level of your countertop. Your imperfection is now fixed.

Thanks, I have read that. The crack is very thin so I wonder if it will actually fill it? May give it a try though.

Yes, a professional installer used super glue. He just ran a bead along the crack and let it soak in. When it dried he ran a razor blade along the surface. He repeated this a few times until the crack was fully filled.

Contact this guy and see if he will travel to TV. He's in Sarasota. If he won't, he will give you a good reference.

There are several versions of super glue, you should try the NON gel type first as this will soak into the crack. If it does not completely fill the crack, then follow-up with the gel type. The razor blade is a good idea for removal of excess, followed up by a good polishing.

The treated fumed silica in the gel type makes those formulas advantageous if the crack extends to the vertical edge of the quartz. The gel formulation would offer less chance for dripping along the vertical edge.

I agree that applying super glue to the crack is worth trying, if it can actually fill in a depression on the surface. But, I don't think the super glue will do anything to increase the strength of the quartz slab, or to prevent future cracking.

Take a hammer to it.

Yeah he's going to travel from Sarasota to fill a crack. Spend 4 hours on the road to do 1 hour job.

Of course the customer will gladly pay and that's $300 for him just to arrive.

Super glue comes in different speeds it takes to cure. Some as much as one minute others almost instantaneous. I would suggest the longer cure type, it will seep deeper onto the thin crack. Give it ten mounts and cut away on an angle not directly across the crack.

Super Glue is what the Pros use.... granite will accept a hot pan, but quartz and quartzite will Not! Bless you fellow Villager

Nothing will work. Houses vibrate a lot when the heavy winds come.

Here is the Thermodynamics.... heat, cool , heat, cool, heat, cool.
Rigid materials like Quartz do not like that.

Best bet buy one of those glass food prep boards with standoffs, it will thermally insulate the counter from the Air Fryer

Might be covered by your HO insurance. If it can't be fixed without being noticeable, replacement would apply if it's a covered claim.
