How to repair damage to granite worktops05-Feb-2015 No matter how careful you might be, accidents do happen over time and your granite worktops might get damaged. Now, if you clean your worktops regularly and seal them as and when needed, then you're already on the right track to caring for them as best you can.
When performing even the slightest DIY repair job on your granite countertops, you will need to remove the finish first. You cannot repair damage without ridding the area of the protective layer. This applies to all repairs, no matter how small they might seem.
If you accidentally chip or scratch your granite worktops, you should remember that there is bound to be some stone residue stuck in the scratch or hole. Use a small brush (like a toothbrush) to clean the damaged area out before you apply a filler and sand it down. If you apply the filler without clearing the debris, the job won't last.
Remember to never use harsh chemicals during the cleaning or repair process. Use only stone friendly products with a neutral pH. Vinegar or anything acidic or abrasive will only cause more harm than good.
Once your repair job is complete and the repaired area has had time to set and dry, you should re-apply the finish to help protect and preserve your hard work. The finish will also help make the repairs that much more unnoticeable and help everything blend together nicely for that good as new appearance.
