I am doing my first attempt at polishing travertine using the Vibe and Stone Flash 5 step system. I started by cleaning the grout with Groutmaster and then I did about 3 passes of each step from 1 through 5, cleaning in between and finishing with a neutral pH cleaner with a floor scrubber. I haven't achieved a high gloss/polished appearance. The stone does look good when wet but dulls when dry. Prior etching, roughness and any other irregularities all are gone. I don't have a gloss meter to show objective changes. The floor looks good but I would like it looking more polished. Is this just a matter of further passes with Step 5 or am I missing something? Thanks in advance for any help.
