Concrete repair and replacement must becompleted prior to application of Protectosil CHEM-TRETE40 D. Patching materials, caulking, sealing materials andtraffic paint must be fully cured before applying ProtectosilCHEM-TRETE 40 D.All surfaces must be cleaned to remove all traces of dirt,dust, efflorescence, mold, salt, grease, oil, asphalt, laitance,curing compounds, paint, coatings and other foreignmaterials. Acceptable surface cleaning methods includeshotblasting, sandblasting, waterblasting and using chemicalcleaners. Check with your Protectosil representative toverify that surface preparation is adequate.Protectosil CHEM-TRETE 40 D should be applied usinglow-pressure (15 to 25 psi) pumping equipment with a wetfan type spray nozzle. Alternate methods include usingeither a power roller with a 1" nap or a brush. Do not alter ordilute the material. Do not apply to a wet or damp substrate.A test patch should be applied to the substrate to verifycoverage rate, desired results and application conditions.On vertical surfaces, apply Protectosil CHEM-TRETE 40 Din a flooding application from the bottom up, so the materialruns down 6 to 8 inches below the spray pattern. Coveragerates on limestone surfaces are between 75 and 125 ft 2 /gal.Multiple applications may be needed for denser consolidation.Surfaces such as polished marble may have higher coverage rates.For warranty qualification, your Protectosil representative cangive an exact coverage rate for your particular project.
