I’d have to see a photo of your floor to be absolutely sure of my recommendation but it’s true most adhesive products will damage a decorative concrete floor’s finish. When additional construction is planned, we generally recommend acid staining, applying one coat of sealer, and covering the floor with a drop cloth wherever possible. The coat of sealer is applied to make clean-up easier prior to applying the second coat of sealer and finally, the wax. Sanding would be a good choice if you had large areas affected by the tape removal but likely in your case, the areas were more isolated. Another approach would be removing the sealer and wax only where the blemishes occurred with a stripper product such as Soy Gel Professional Paint and Sealer Stripper available on our website or Xylene (chemical with high odor). Clean thoroughly. The acid stain will be unharmed and the sealer/wax can be re-applied with a foam brush or similar applicator. You might still see some slight differences in appearance but this is by far the easier and most effective option for correcting tape-related blemishes.

Thank you and good luck.
