Epoxy Measurement and Application Tips
Epoxy projects require precise volume calculations. Unlike paint, epoxy coverage is determined by volume, not square footage alone. The required volume is always $\mathbf{Length \times Width \times Thickness}$.
Key Factors Affecting Epoxy Needs
Absorption and Sealing
Porous surfaces like concrete or wood will absorb the first application (the primer/seal coat) significantly, potentially requiring 10-20% more material than the calculation suggests for that first layer. Consider using a dedicated primer before the flood coat.
Waste and Spillage
Epoxy is tricky—you'll always lose some material that remains stuck to the sides of your mixing bucket, mixing sticks, or application tools. It's standard practice to **add a 5-10% buffer** to your calculated volume to ensure you don't run short mid-pour.
Mixing Ratio and Safety
Always Follow Manufacturer Ratios
While this calculator gives you the **total volume** of *mixed* epoxy, the product typically comes in two parts: **Resin (A)** and **Hardener (B)**. You must mix these two parts according to the manufacturer's ratio (e.g., 2:1, 3:1, or 1:1 by volume or weight) precisely. Incorrect ratios prevent proper curing and can ruin the project.
