MARSHALLTOWN Industrial Concrete Sprayer 3.5 Gallon — Epoxy‑Lined Tank, Viton Seals, Brass Wand

MARSHALLTOWN's 3.5 gallon Industrial Concrete Sprayer is a heavy‑duty, metal pump sprayer built for applying concrete sealers, curing compounds, form oils and solvent mixes on job sites.

This industrial sprayer is designed for contractors who need a portable, robust tool for consistent coverage of concrete and masonry surfaces. It combines a rust‑resistant epoxy‑lined tank, a brass wand and fittings, Viton seals for chemical resistance, and a long hose to help reach awkward areas. The unit is built to tolerate heavy use on jobs where reliability and easy maintenance matter.

How does this sprayer handle harsh chemicals and solvents?

The sprayer uses Viton seals intended to resist many solvents and acids, and an epoxy lining to protect the 3.5 gallon tank from corrosion and staining. However, chemical compatibility varies by formulation, so you should confirm with your chemical supplier before first use and inspect seals before every fill.

• Viton seals provide broad chemical resistance but require verification per product.
• Epoxy lined tank prevents rust and staining from common sealers and oils.
• Inspect seals and fittings regularly to maintain chemical integrity.

What features improve performance for concrete sealing and curing?

The sprayer includes a durable metal pump, a brass wand and brass fittings for smooth, consistent spray action and reduced wear. It accepts up to 35% solids in compatible products and delivers controlled atomization for even coverage over flat or vertical concrete surfaces.

• Industrial metal pump for steady pressure and long life on busy jobsites.
• Brass wand and trigger reduce corrosion and improve durability.
• Accepts products up to 35% solids for thicker sealers and compounds.

How easy is it to use around a busy construction site?

The unit is sized for portability while offering a 48‑inch hose to reach tight corners, forms, and vertical surfaces without moving the tank constantly. The ergonomically designed trigger and brass wand help operators maintain control during long spraying sessions.

• 3.5 gallon capacity balances run time and portability between refills.
• 48" hose provides extended reach in confined or elevated areas.
• Comfortable trigger and wand setup reduce operator fatigue.

What maintenance should I plan for reliable operation?

Routine inspection and cleaning keep seals, wand, and fittings functioning and prevent cross‑contamination between products. Flush the system after use, check the Viton seals before each fill, and keep brass components free of abrasive residue.

• Flush tank and hose after each use to avoid buildup and clogging.
• Inspect and replace seals if cracked, swollen, or worn.
• Store dry and clean to protect epoxy lining and brass parts.
