Quick answer: Primer/Sealer cost in 2026
Primer/Sealer costs about $25.00 per gallon (typical range $15.00–$40.00) plus roughly $20.00 per gallon for installation labor, or about $45.00 per gallon installed. Order 10% extra for waste: 500 gallons becomes 550 gallons, about $13,750 in material and $23,750 installed. HammerIO planning estimates, a national baseline adjusted by regional factors on city and state pages.
Labor is priced by painters: the BLS OEWS May 2025 median wage is $23.75/hr nationally, $29.53 in New York and $21.90 in Dallas. Last reviewed .
Estimate Primer/Sealer Cost Before You Order or Compare Bids
Step 1
Price Primer/Sealer by the right unit
Start with the measured quantity in gallons, then compare the current unit range of $15.00 to $40.00 per gallon.
Step 2
Add waste, labor, and install accessories
Apply the default 10% waste factor, then include labor, fasteners, trim, adhesives, delivery, rental tools, and other project-specific accessories.
Step 3
Use the result to check written bids
Compare the calculator result against supplier units and contractor line items, then verify code, permit, and site-condition assumptions before ordering.
