How to Repair Granite Countertop Scratches How to Repair Granite Countertop Scratches
To repair granite countertop scratches the average Do-It-Yourselfer needs to apply a little caution, but can save thousands of dollars when compared with replacing the countertop. Scratches, scuffs, and unsightly abrasions can happen with normal use even when people are being careful.
Most importantly with granite, keeping a close eye on the buffing out of a scratch is imperative. Often slight abrasions will do the trick and the project can quickly out of hand with too much force. To avoid ruining the countertop altogether, try to repair the scratches by polishing them out slowly.
Step 1 - Resin Scratch Stick
For many small scratches a resin scratch stick is the best place to begin because it will not hurt the polish, but still leave the scratch invisible. Though the scratch will still be present on the countertop, it will be not be seen by the naked eye. Take the resin scratch stick and scratch it across the mark in the countertop. The scratch stick will scratch off and remove the unsightly scratch. If this doesn't work, or you feel it is inadequate for the job, proceed to Step 2.
Step 2 - Ultra Fine Steel Wool
If the scratch is so deep that the resin stick will not remove it, ultra fine grit steel wool or sand paper is the next option. Slowly abrade the surface of the scratch with the steel wool. Begin lightly and increase the pressure till it becomes effective. It is much worse to take off too much than too little.
First, work the either side of the scratch to minimize the polish and then begin scouring across the scratch. Do not use circles but small linear movements. In time the scratch will be scoured out and removed. Follow with rubbing compound and stone sealer to complete the finish. If this doesn't completely work, move on to Step 3.
Step 3 - Diamond Sanding Block
Diamond sanding blocks are one step up from the abrasive qualities of sand paper or steel wool. With find grit diamonds adhered to paper and then attached to a sanding block, these tools allow you apply the hardness of diamonds to the granite surface. This should be done very carefully as the diamonds will further scuff other areas which have not been damaged if you are not careful.
Move the sanding block along the sides of the scratch first and then begin crossing over the scratch to buff it out. Small motions back and forth should be sufficient. Rinse the surface clean of debris and dust (there should be plenty) and then apply the rubbing compound to buff out any uneven marks. Finish with the stone sealer to preserve the finish and quality shine.
Step 4 - Call the Professionals
If these steps have been tried and the scratch still remains it is far too deep for home repairs. Rather than permanently damage the valuable granite surface, call professionals for advice. Professional sealing every other year can also help prevent scratches.
