🔬 Engineering Methodology & Benchmark Analysis

For 100%-solids cycloaliphatic epoxy systems, 1.0 liter of mixed resin covers exactly 1.0 square meter at a wet film thickness (WFT) of 1.0 millimeter (approximately 40 mils) on a sealed, non-porous surface.

Water-based hardware-store kits evaporate 40%–50% of their volume during curing, leaving a thin film that peels under hot car tires. Always verify whether your supplier quotes 100%-solids volume.

🛠️ Step-by-Step Engineering Calculation Guide

  1. Total Floor Surface Area (Square Meters — m²): Configure "Total Floor Surface Area (Square Meters — m²)" (default benchmark: 45) or select an industry preset.
  2. Coating System Thickness (mm / mils): Configure "Coating System Thickness (mm / mils)" (default benchmark: 1.5) or select an industry preset.
  3. Concrete Substrate Condition & Absorption: Configure "Concrete Substrate Condition & Absorption" (default benchmark: 1.15) or select an industry preset.
  4. 100%-Solids Epoxy A+B Price per Liter: Configure "100%-Solids Epoxy A+B Price per Liter" (default benchmark: 22) or select an industry preset.

❓ Frequently Asked Technical Questions

Why do epoxy floors bubble or peel after a few months?

90% of failures come from skipping mechanical diamond grinding (acid etching is insufficient) or applying a thick coat directly onto unprimed porous concrete that outgasses as temperatures rise.
