We take pride in the ability to make the tack strip holes disappear, most often by insuring that the patch compound for the job stains the the same color when sealed. A color that matches before sealing may not match at all when sealed. When the patches do not stain to match, we have other methods that blend them in with the unpatched normal floor.
LuvMarley, you can still improve the appearance of your tack strip holes. If you have a solvent based sealer already applied, the job is easy to do.
An interesting note about the bank lobby floor in the picture - we repaired damage to the stain which happened mid-construction. This may have been battery acid leaking from a scissor lift through the protective covering, but what ever the cause, it left about 4 sq ft of cream color in the sea of beautiful brown. We were finally able to match the color to the point the 'issue' disappeared.
