Use the same tool you used to mix the epoxy to apply it to each of the surfaces individually first.
Then stick them both together pressing it against each other. Epoxy will begin to ooze out of the joint area, clean it off with a rag. Use shims to ensure that both the original surface and the broken piece are perfectly leveled. Make sure no one touches the repaired area for the amount of cure time specified by the contractor. Normally a day or two. Now, since most epoxy shrinks as it dries, there will be a slight deppression to fill at the joint area.
If so, you will need to apply a second coat of epoxy. Repeat the same procedure used for filling a crack in order to get the surface as smooth and flat as possible. In order to make your granite surface look whole again, the repaired area will need to be polished.

My countertop 7-yrs-old had a 6" crack running across and thickness wise, repairman insisted that I put a hot pot on it; not true. He put the glue down and 4 years later the crack has grown and is five inches from the other edge. Repairman says the crack is the same and nothing further can be done.

What is the biggest cause of such cracks, and what sort of steps can I take to prevent them in my own granite countertops? Thanks, Camille B. So, you don't have to be too worried about creating a crack once installed. Usually cracks that occur after installation are due to an accident.
For instance: a refrigerator tips over when moving and cracks the countertop edge. Or something heavy was dropped on the surface or edge. Granite is tough and durable, but rigid, so it's helpful to keep this in mind. Is plywood necessary by: Ryan No plywood is not necessary IF your foundation and cabinets are in good shape and offer solid, even support at regular intervals. Plywood can be useful when installing over old or irregular cabinets or over cabinets that are unlevel due to foundation issues.
There is some controversy in the industry regarding support. Some will insist it is necessary to "rod" every slab. This is a process to insert metal rods in the underside of the slab. Others argue that rodding only serves to weaken the slab because grooves or slots are cut into the granite for inserting the rods.
But rodding is a bit different than using plywood. Also, the other issue with using plywood is that you must use a laminated edge in order to cover the plywood that you'll see sitting above the cabinets.
Molding matching the cabinets can be used, but looks a bit wonky. A laminated edge is fine with 2cm, but often doesn't work so well with a 3cm slab since the edge then becomes too big. So, even with plywood raising the level of the slab, the laminated edge hiding the plywood may interfere with the drawers, etc.
But again, typically not a problem with 2cm. I'd say forget the plywood, except for the above stated fairly rare circumstances.
Is plywood support needed for 2cm granite? From what I have read on the internet, it is, but some installers say it's not worth it. We are just wasting our money. What do you think?
Fissure or Crack by: Anonymous Article was great in trying to understand how to best approaching talking with my fabricator and installer. We have a fissure prone granite Cold Stone installed in our kitchen and extended counter into the dining area. When last sealing, I noticed what I called a crack in a narrower section because it was physically felt when buffing the sealer.
I contacted the fabricator and they quickly referred to it as a fissure and indicated it is common with our granite, but they would contact the installer for a service call. Story of the installer being less than responsive aside - I happened to look at the underside, and I can see and feel what appears to be a skim coat of something over the top of the reinforcing mesh that appears to follow the raised area felt on the top of the counter.
Does this indicate it had been a known area of concern identified by the quarry or during fabrication? If I can feel it on the surface, and it runs from front to back, this would be a crack, not a fissure? I'm past the fabrication warranty - should I have any recourse knowing it appears the mesh area was additionally reinforced? Fissures can and usually do run through the entire slab thickness.
However, if you are feeling a lip on the top surface, then yes it is probably a crack. The mesh is normal and commonly used. Although, if you are feeling some substance like a hardened glue following the same line as the "fissure", it is likely a crack that the installers knew about and tried to reinforce.
It could be a fissure they thought was vulnerable to cracking, though too. But feeling a lip on the surface is usually a crack. You may have a case that they knowingly installed a cracked slab, but you'll need to get some local help to confirm a diagnosis.
The cutout for the stove top was too small, but the installer shoved the stove top into the space. Now there are hairline cracks radiating out from three of the four corners of the cook top hole and the stove top 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 even hooked up sink or stove top yet. They claim epoxy will solve the problem. Considering they couldn't think ahead or be patient enough to do the job right, I wouldn't trust any countertop repair job they were going to attempt.
A single hairline crack somewhere, I wouldn't worry about, but multiple cracks radiating from 3 corners of the cook top cut-out You will be constantly stressing this area too with additional weight and pots and pans banging around if you cook like me anyway! 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 cracked granite and improve the integrity in the area, but cut-outs are weak areas.
Even with repair and any support that they may be able to add the entire area is compromised. Epoxy can be very strong and a stellar repair may be sufficient, but I'd want a granite repair specialist to do it. Now, I don't know how long or how many cracks there are, so maybe it sounds worse than it is and you're thinking maybe just to negotiate a much cheaper price and an adequate repair.
That's an option However, there is still the issue of the broken cook top. You need a new one So, you need one that will fit this cut out because enlarging the cut out now is risky Maybe you get lucky and find one, but this is a bassackwards way of doing it.
