Description
Manual pump sprayers lose pressure mid-stroke and produce uneven concrete sealer coverage that causes blotchy curing finishes. The DEWALT 20V MAX XR Concrete Chemical Sprayer Kit delivers constant atomization pressure across commercial slabs without hand pumping. It feeds high-viscosity curing compounds and form release oils at up to 110 PSI. Cold chemical viscosity thickens flow through small spray tips.
An internal die-cast aluminum pump body houses Viton seals and fluoroelastomer check valves to resist harsh aromatic solvents, xylene carriers, and form oils. The brushless motor couples to a dual-diaphragm pump core through hardened steel planetary reduction gears. Fluid lines incorporate nylon-braided high-pressure vinyl hoses and heavy-wall chemical-grade polypropylene fittings that stop solvent breakdown.
Concrete Chemical Application Hardware Systems
Consistent spray patterns eliminate puddling and dry spots across large commercial floor pours. The balanced carry frame stabilizes the unit across rough aggregate sub-bases.
- 110 PSI maximum discharge pressure maintains consistent chemical mist patterns through wide fan nozzles.
- Viton elastomer pump seals resist chemical breakdown from high-solid solvent-based sealers and curing agents.
- Five-position variable pressure selector dial tunes liquid output from 35 PSI up to 110 PSI.
- Commercial brass spray wand features a shutoff valve with an integrated lock-on mechanism for continuous passes.
- Protective battery door encloses 20 Volt packs to block chemical overspray and rain penetration.
- Molded structural base protects delicate slab finishes from scuffs and metal gouge marks.
- Integrated carry handle centers payload balance when transporting the power unit across rebar grids.
Battery Telemetry Fluid Pressure Benchmarks
Pumping high-viscosity curing compound at 80 PSI draws 4.8 Amps from the 20 Volt 5.0 Amp-hour lithium pack. The pump unit delivers a measured 0.48 GPM across 50 feet of hose without pressure spikes. Brushless motor housing temperature rises 18°F above ambient after spraying 40 gallons of solvent sealer continuously. Sound emissions peak at 66 dBA measured three feet from the pump housing.
Chemical Deployment Scope Service Directives
Commercial concrete finishing crews applying form release, bond breakers, and curing compounds achieve uniform coverage with this mobile sprayer. Do not buy this sprayer for water-borne latex paints or aggregate-loaded slurry coatings because solids will clog internal diaphragm check valves. Never leave hot solvent sealers inside the pump overnight.
- Flush three gallons of clean xylene or mineral spirits through the pump circuit after every workday.
- Blow dry compressed air through the brass wand filter screen each morning before mixing fresh product.
- Inspect the hose connections for chemical softening or swelling every 30 days of service.
