Epoxy paint calculator

This epoxy paint calculator helps estimate how much epoxy coating you need for your project, what it will cost, and how thick your coatings will be in both wet and dry stages.

Here is an example on how to use our epoxy paint calculator:

Scenario:

• 1000 sq. ft. garage floor
• Product: 100% solids epoxy
• Target build: 10 mils
• Product cost: $100/gallon
• Loss: 10%

Inputs:

• Volume Solids = 100%
• Mils = 10
• Loss = 10%
• Cost = $100
• Area = 1000

Outputs:

• Coverage/Gal = 160 sq. ft.
• Coverage after loss = 144 sq. ft.
• Gallons needed = ~7
• Total cost = ~$700

 

Section 1: Epoxy Paint Calculator

Inputs (yellow cells):

1. Product Name – Enter the name or code of the epoxy you’re using.
2. Volume Solids % – Get this from the product’s TDS (Technical Data Sheet).
3. Mils – Desired dry film thickness. Example: 8 mils for a garage floor.
4. Loss % – Estimate application loss (10-30%). For floors, 10–15% is typical.
5. Cost per Gallon – Wholesale or retail price.
6. Project Square Feet Total – Measure your space: length × width.

Outputs (green cells):

• Coverage/Gallon – Theoretical coverage at the entered thickness.
• Coverage After Loss – Adjusted for job site waste and inefficiencies.
• Cost per Sq. Ft – Includes waste.
• Gallons Needed – Rounds up for practical purchase.
• Estimated Total Cost – Based on gallons × cost.

Section 2: Wet & Dry Film Calculator

Inputs:

• Volume Solids % – Use adjusted value if thinning.
• % Thinned – Enter 0–20% if you’re adding solvent/reducer.
• Wet Film Thickness – What you plan to apply.
• Dry Film Thickness – Your required final build (typically from spec sheet).

Outputs:

• Adjusted Volume Solids – Auto-calculates new solids after thinning.
• Dry Film Thickness – Shows what build you’ll get from the applied WFT.
• Wet-to-Dry and Dry-to-Wet – Helps determine how thick to apply wet to achieve target dry.

 

Extras: Epoxy Application Tips

1. Surface Prep is Critical: Ensure clean, dry, and profiled substrate.
2. Measure Mils: Use a WFT gauge during application.
3. Mix Properly: Use drill mixers. Follow pot life guidelines.
4. Roller vs. Squeegee: Large areas often use squeegee + backroll.
5. Ventilation & PPE: Always ensure airflow and wear respirators.
