Square Footage Calculator

Enter the total square footage of your project to estimate gallons of 545 primer needed. Coverage is calculated using 545 Base + Converter once mixed. Results are estimates only and actual usage may vary based on surface prep, application method, and film thickness. This calculator is intended to get you close, not guarantee exact quantities.

Surface Preparation

Fiberglass / Gelcoat

Sand with 150-220 grit before priming.

Aluminum

Blast or grind to a 2-3 mil surface profile.

Steel

Blast to SSPC-SP10 or grind to bright metal.

Wood
