flexible grout

Q. I have used grout with a silicone additive on travertine flooring which is laid over heating. Unfortunately the grout has dried rapidly so I have not been able to wipe it off as I normally would. Please can you recommend a cleaning product or machine which can do the task please.

A. Once the grout has cured it is difficult to remove chemically. I would suggest that the floor be honed to remove the residue. This is really not a do it yourself project. I would recommend you call in a Certified SurpHaces PRO Partner. To find one in your area, contact us.
