Repairing a Granite Countertop

Factual Questions
1

I somehow managed to drop a heavy drinking glass and chip the inside edge of the granite that surrounds our kitchen sink. The chip is about 3/8" in size and has left a sharp edge. The slab is about 4’ by 6’, so replacement isn’t an option. I have dropped a variety of things on granite before and never chipped them, so this is a new problem for me.

Is there a material that I can put in the chip that would harden and replace the piece that is now missing?

I suppose I could pay someone to grind the edge all the way around the sink to even everything out, but that seems like a lot of work/effort/money for what is basically a small chip.

Any DIY suggestions?

Superglue is what the countertop installers will use. Do you have the chip that came out? If so, use that, superglue it in place and let the glue flow around it. You might need to do a couple applications to build up the depth. Sand with 400 grit sandpaper.

I don’t have the chip. It apparently went flying and I didn’t notice the granite was chipped until the next day. So I need to build up the material and try and match it to the color of the granite. Is this even possible, or is grinding the only answer?

a counter store may have repair kits with stone powder and resin.

don’t take your countertops for granite

I installed a granite countertop for the wet bar in our rec room. Dumbest move I ever made. Looks nice, but completely impractical.

We generally didn’t worry about color matching. the superglue is clear and it will blend pretty well without it. What color is the top? The repair kits made of resin are not very useful, they look good for a few months then yellow and fall out.

Grinding a new bevel on the top can work but it’ll cost you. Without seeing a picture of the chip it’s hard to say what I would recommend…hint hint:)

Why is your top impractical CM? I tell people to expect the top to develop a patina and not to worry about it. It’s a slab o’ rock y’know, not too much you can do to it.

Thanks for the info - now I have an idea of what’s needed to do in order to fix my sister’s stone counter where someone dropped a hammer.

You say to make the initial application of epoxy with “hot” epoxy. Are the following layers also with the catalyst, or without it?

She’s also got a bathroom vanity top that looks like it was made with a couple dozen rectangular “bricks” of granite. Some of the joints are, shall we say, less than lovely but not bad enough that i’d think they need to be filled with epoxy. It sounds like I should be able to just flow some super glue on them to fill in the gaps - any particular brand you can recommend?
