To achieve an immediate high-gloss finish to a silicate-treated concrete floor, apply Duro-Polish or Duro-Polish Plus. Floors recently treated with silicate type liquid hardener and dustproofers typically provide gloss readings in the range of 15 to 25 gloss units when tested with a Horiba IG-320 meter measured at a 60 degree angle. The same floors, after treating with Duro-Polish, typically exhibit gloss unit readings in the range of 35 to 50.
