A professional strength floor stripper designed for the removal of "tough to strip" finishes and sealers. Fast penetration of built-up finish and sealer layers. Designed to work the first time by reducing "re-strips." Works in cool water and uses a variable dilution rate to match the job. Not for use on marble floors. pH: 13. Dilution 1:4 - 1:6 for heavy build-up, 1:8 - 1:10 for light build-up.
