I have granite countertops and am in the process of replacing the electric cooktop with a gas one. The cutout is 29 1/2 x 20 1/2
the cutout that the installation calls for is 29" x 19". I did not make the original cutout so would like to epoxy some wood to the inner edges of the cutout to make it the correct size. The cooktop that will be going in is 30 5/16 x 21 1/8 (at the outermost edge of the curve). I cannot find any cooktop that needs the cutout i have. I would like to know what epoxy i can use to hold the 1x2 strips of wood to the granite and if it is safe to use near a cooktop. I do not know what temperatures the cooktop can get to. If it helps here is a link to the cooktop i ordered.

Thanks

 

Frigidaire has cooktops requiring 29 7/8 x 20 1/2 cut out.

 

I did not see any on their site...Do you have a specific model? i now see electric ones, but i am hoping for gas. The electric coil cooktop in there now is terrible
Thanks

 

If it were me, I would go to a stone store and have them cut a strip of granite to fit and to match your existing countertop. You should be able to get a close match. Use the same epoxy they use on countertop joints and provide some suppor epoxied clips) underneath.

Before you choose a new cooktop, check out the flat surface electrics. They may not have the same cooking control as gas, but they are soooo easy to clean and they look great.

 

Thanks, I went to a granite place a few hours ago and they would cut a piece that i could epoxy in. I think the cooktop (already ordered) will be ok in terms of covering the hole, I would just prefer added reinforcement, which is why i would epoxy either wood (most likely granite now) in for added stability. We looked at the ceramic cooktops and really prefer the control of gas.

 

Since the new top will cover the hole, it really doesn't matter what you fill in the space with. See if you can find a heat tolerant epoxy so it doesn't overheat and fall out. As cwbuff said use wood strips epoxied perpendicular to the stone or wood strips underneath for extra support.

 

Any ideas on a good heat resistant epoxy. How hot could it really get under a cooktop? The granite place said they would give me some epoxy if i brought in a jar.

 

Actually, I've had second thoughts about my earlier advice. If the new stove has a foam gasket around the perimeter (applied by the installer) it should be pretty well isolated from the countertop, and not much heat will transfer to it. So the epoxy (or polyester) adhesive from the granite supplier should be fine.

 

THanks for the advice...I see on some of the all ceramic electric cooktop installtion instructions, that a gasket comes with. I wonder if this is common on gas on glass cooktops as well. I assume it wouldnt hurt to put a gasket anyway, if it didnt have one i wonder what would prevent liguid from getting under the cooktop? A bead of silicone?

 

You could seal it with silicone. Use clear and clean it up with denatured alcohol.
