Epoxy Flooring Cost Calculator

Understanding Epoxy Flooring

Choose the right epoxy system for your application.

  • Water-Based Easy application, good for light traffic.
  • Solvent-Based Better adhesion, moderate durability.
  • 100% Solid Maximum durability, no VOCs.
  • Metallic Decorative finish, unique appearance.

Design Considerations

Traffic

Consider usage intensity.

Chemical

Check resistance needs.

Moisture

Test substrate condition.

Aesthetics

Choose finish options.

Preparation Guide

  • Basic Prep Clean and etch surface.
  • Medium Prep Diamond grinding, patch repairs.
  • Heavy Prep Major repairs, leveling.
  • Testing Moisture and adhesion tests.

Application Tips

  • Temperature Monitor application conditions.
  • Mixing Follow ratios exactly.
  • Timing Watch recoat windows.
  • Protection Allow proper cure time.
