No, standard Birchmeier sprayers such as the 4 Gallon (15K) Backpack Sprayer (109600001) should not be used to apply harsh chemical such as concrete sealer. Neither the seals nor the other components would hold up to these materials. We do sell other sprayers that can be used for concrete sealant, such as the Chapin Concrete Sprayer 3.5 Gallon (1949). The Chapin Concrete sprayer can be used for form oil and curing compound applications, but not for acetones. If you are only needing to spray a chemical like this one time, you could use an inexpensive sprayer such as the Chapin 1 Gallon Pump Sprayer 20000, and then discard the sprayer after use. (We encourage you to check with local waste disposal agencies for proper disposal.) Please let us know if you have further questions.
