They would only need to be re-cemented if they are removed or replaced. They only need to be replaced if they warp or crack. Keep the fines cleaned up under the grates at least once a year and you probably won’t ever have an issue. The bulk of the sealant is between the grates and along the top there is a ledge and lip that need sealed. If you ever need to take them apart the cement will be obvious and you just apply cement to those same areas. Thoroughly remove any old cement first. Any cement that squeezes up from between the grates can be wiped off with a damp cloth before it cures. Any lumps or bumps on the top of the grates would impede the coal flow down the grates.
If it ain’t broke don’t fix it.
