Spray form oils, concrete additives, and curing compounds reliably on the job site with the Chapin 1449 Industrial Concrete Sprayer. This contractor-grade 3.5-gallon (13.2 L) sprayer pairs a heavy-duty Tri-Poxy steel tank with all-brass wet-side hardware — built to stand up to aggressive concrete chemistry, daily site abuse, and the kind of long pours where a plastic sprayer would fail by lunch.

Model: 1449 · Capacity: 3.5 Gallon (13.2 L) · Vendor: Chapin

Built for Concrete Work

• Wide tank opening: fill faster and limit splashing — critical when you’re pouring viscous form release oils or curing compounds
• Ergonomic pump handle: comfortable two-hand pressurization with reduced wrist strain on long days
• All-brass wet path: brass nozzle, brass wand, and brass shutoff resist corrosion from solvent-based form oils and aggressive curing chemistry
• Tri-Poxy steel tank: three-layer baked-on coating for impact, rust, and chemical resistance — standard on Chapin industrial sprayers
• 3.5-gallon capacity: cover more surface per fill, reduce trips back to the mixing station

What It’s For

• Form oils: apply release agents to formwork before pours
• Concrete additives: spray surface retarders, accelerators, evaporation reducers, and bond breakers
• Curing compounds: apply membrane curing compounds and water-based sealers on freshly placed concrete
• Construction site work: built for the daily abuse of commercial form-and-pour and flatwork crews

Application Tips

• Confirm chemical compatibility for any product not on the manufacturer’s approved list before filling the tank
• Pre-strain thick or particulate-laden mixes to keep the brass nozzle clear
• After use, drain the tank, flush with the appropriate solvent or water, and store with the cap off so seals can dry
• Relieve pressure before opening the tank between uses
• Wear chemical-resistant gloves and eye protection when handling form release oils and curing compounds
