Smith Performance Sprayers 2-Gallon Acid Sprayer — Corrosion-Resistant, Contractor-Grade with Pressure-Relief & Wand Storage

Smith Performance Sprayers 2-gallon acid sprayer is a heavy-duty, corrosion-resistant pump sprayer built to handle acid staining, prep work, and other harsh chemical jobs safely and reliably.

Designed for contractors, stain professionals, and industrial crews, this 2-gallon sprayer combines a mostly poly construction with targeted acid-resistant alloys to extend service life where it matters most. The model 190449 focuses on maintenance ease and operator safety: quick-change pump seals, a pressure release valve, and integrated wand storage reduce downtime and chemical exposure. Included poly fan nozzles cover common spray patterns while compatibility with TeeJet fittings adds application flexibility.

How does this sprayer resist acid and corrosion?

The sprayer uses predominantly polypropylene and other engineered poly parts that are inert to many acidic solutions, while critical wear components use acid-resistant alloys to prevent fast degradation. Corrosion-resistant Monel springs and washers in the shut-off and wand help maintain consistent performance where metal meets fluid. This material selection minimizes reactive breakdown and maintains sealing integrity over prolonged exposure.

• Poly tank and components for chemical inertness
• Monel springs and washers on wand shut-off to resist corrosion
• Acid-resistant alloy fittings at critical wear points

What features improve safety and reduce chemical exposure?

Built-in safety elements focus on both user protection and handling convenience. A pressure release valve lets you safely depressurize the tank before opening, lowering the chance of a sudden chemical spray. The integrated wand storage keeps the spray tip and residual chemical contained when not in use, reducing accidental drips or spills.

• Pressure release valve for safe tank depressurization
• On-board wand holder to contain chemical residue when stored
• Sealed pump design and replaceable seals to limit leaks

How easy is maintenance and repair on the job?

Maintenance is designed for quick field servicing so you spend more time working and less time troubleshooting. The pump uses replaceable seals, check valves, and gaskets that can be changed rapidly without specialized tools, letting crews perform fast repairs between jobs. Using standard nozzle fittings also simplifies parts replacement.

• Tool-free pump seal replacement for minimal downtime
• Replaceable check valves and gaskets accessible from pump assembly
• Accepts TeeJet nozzles for easy parts sourcing

Which spray patterns and flow rates are included?

This sprayer ships with two poly flat fan nozzles to cover common staining and prep applications: a tighter 0.15 GPM at 30° for detail or concentrated coverage, and a wider 0.25 GPM at 70° for broader, faster coverage. Because the wand accepts standard fittings, you can swap in alternate tips for different materials or spread rates.

• 0.15 GPM poly flat fan nozzle, 30° angle for concentrated spraying
• 0.25 GPM poly flat fan nozzle, 70° angle for wide coverage
• Compatibility with TeeJet nozzles for expanded tip selection

Who is this for: The Smith Performance Sprayers 2-gallon acid sprayer is intended for professionals and serious DIYers who regularly work with acid stains, etchants, or other corrosive chemicals and need a robust, serviceable sprayer. It's a fit for contractors, concrete finishers, restoration crews, and maintenance teams that require corrosion resistance, rapid field maintenance, and safer handling features during heavy chemical use.
