Smith Contractor 1 Gallon Sprayer, Model 190504

The Smith Contractor 1 Gallon Sprayer (Model 190504) is a compact pressure sprayer built for lawn treatment, commercial cleaning, sanitizing, and applying harsh chemicals. It gives homeowners and professional cleaners a versatile tool designed to safely handle demanding chemical mixtures.

For durability and chemical resistance, the unit features Viton seals throughout the pump assembly and the commercial-grade shut-off handle. The sprayer is equipped with a 14-inch poly wand and comes with five distinct nozzles: a poly adjustable nozzle, a brass adjustable nozzle, two flat fans, and a specialized foaming nozzle. An in-line filter built directly into the comfortable shut-off handle helps keep debris from reaching the tip, while the lock-on feature enables continuous spraying without hand strain.

A built-in pressure release valve vents tank pressure before you open the lid, helping prevent direct chemical contact. While the 1-gallon capacity keeps the unit lightweight and easy to carry, it does mean you will need to stop and refill more often when tackling large-scale yard or floor projects compared to higher-capacity tanks.

Verdict: The Smith Contractor 190504 is a practical choice for anyone needing a heavy-duty, chemically resilient sprayer for targeted outdoor treatments, cleaning, and sanitizing. Its selection of five nozzles and safety release valve make it well-suited for varied chemical applications around homes and commercial job sites.
