For concrete staining, sealing, cleaning, and treatment, Chapin manufactures industrial sprayers with input from chemical and construction professionals. Tri-Poxy® steel tanks have triple-layer protection from rust, corrosion, and dents. Polyethylene tanks are resistant to industrial chemicals. Wide mouth openings lessen splashing when filling and makes the tanks easier to clean after each use. Engineered seals and gaskets with proven elastomers ensure a high level of chemical compatibility and the unique Tri-Lock mechanism keeps the pump cap tightly locked. These sprayers were engineered with industry in mind, while also being recommended by homeowners for the tough, home improvement and gardening jobs.
