The tank is constructed from coated steel and rated to a maximum working pressure of 60 psi. A Tri-Lock seal feature locks the pump cap tightly to prevent pressure loss during operation. Synthetic rubber seals and gaskets resist degradation from harsh concrete treatments and chemical solutions. A brass wand and brass nozzle deliver a focused stream pattern, and the reinforced hose holds up under repeated flexing. The wide-mouth opening measures 4 inches in diameter for fast, clean filling and easy tank cleaning. Licensed contractors and concrete surface professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThe CHAPIN 1979 is suited for applying concrete sealers, curing compounds, and chemical surface treatments in both residential and light commercial settings. The poly holster keeps the 24-inch brass wand and nozzles secured to the tank when the unit is not in use, reducing jobsite clutter. The coated steel tank resists corrosion from the acidic and alkaline solutions commonly used in concrete surface preparation and maintenance. This sprayer is intended for ground-level hand-carried use on flatwork, hardscape, and masonry surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoated steel tank rated for chemical-resistant use up to 60 psi maximum pressure\u003c\/li\u003e\n  \u003cli\u003eTri-Lock pump cap seal prevents pressure bleed-off during application\u003c\/li\u003e\n  \u003cli\u003e24-inch brass wand with brass nozzle delivers a focused stream spray pattern\u003c\/li\u003e\n  \u003cli\u003eReinforced hose resists kinking and chemical exposure\u003c\/li\u003e\n  \u003cli\u003eWide-mouth 4-inch opening simplifies filling and interior cleaning\u003c\/li\u003e\n  \u003cli\u003ePoly holster secures wand and nozzles to the tank during transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with concrete sealers, curing compounds, and chemical surface treatments.
