Polishing granite cracks to remove the edges of the crack and knowing how to blend the crack itself with the surrounding surface color and shine requires experience, knowledge and skill. The choice here depends on the nature and severity of the crack.Įither way the crack will remain easily visible and palpable unless the surface is then re-polished.įilling or gluing the crack together could be a DIY job or something your installer could do, however, re-finishing the surface definitely is not a DIY project. Installers can do minor repairs, but granite crack repair is a major repair (with a separated crack).Ī person who has made crack repairs before knows the products and methods required and won't be experimenting or learning as they go.Ĭracks in granite are repaired first by filling with an acrylic or using a color-matched epoxy to glue the pieces back together. You'll end up with an ugly scar filled with epoxy. The typical granite installer is not experienced enough to artfully repair a crack in granite. Separated cracks happen from a heavy impact, standing on the granite countertop, or foundation movement and require repair.Īn experienced granite repair specialist is preferred for cracks in granite, marble or any natural stone. Separated cracks have a gap, are easily seen and felt, and have a lip. In some cases, additional support in the area could be beneficial. Hairline cracks generally do not need repair, will not get worse, and do not affect the use, cleaning, or integrity of the countertop.
But it can happen even with the most careful install and there’s no guarantee it won’t happen with the replacement slab. Naturally, many homeowners want the cracked slab replaced. Typically, such cracks happen around sinks or other cutouts with thin sections of granite. Hairline cracks typically cannot be seen or even felt easily, do not have a lip, and no gap or separation of the crack.Ī hairline crack can occur during install as the extremely heavy and rigid slab is moved into place. Although, your installer may not be the best one for the job. My husband also realized that there is no plywood support underneath the countertops, which really raises more concern for us at this point.Ĭould the lack of plywood support be the reason for this crack and should we insist that they come back and reinstall with plywood?ĪNSWER:Certainly you should have the installers return to assess the damage and, if needed, mend the granite crack. Not too noticeable, but we are concerned about any additional problems it might cause. The crack goes from one wall of the corner to the other. We found a crack in the granite in the corner.
