Primer Calculator
Calculate the primer needed for your painting project. Understand how surface area, number of coats, and primer type affect your project cost and material requirements.
Step 1: Project Details
Understanding Coverage
Primer coverage varies by type and surface. Most primers cover 200-400 sq ft per gallon. Rough surfaces like masonry require more primer than smooth surfaces like drywall.
Step 2: Cost Details
About Coverage Rates
Coverage depends on surface porosity and texture. Smooth surfaces get better coverage. Porous surfaces like raw drywall or masonry absorb more primer and may require additional coats.

Primer Cost Analysis
Primer Calculation Formula
Primer Needed (gallons) = (Surface Area ÷ Coverage per Gallon) × Number of Coats
The total primer needed is calculated by dividing surface area by coverage rate, then multiplying by number of coats. Labor costs are based on surface area and condition, with additional costs for surface preparation.
