How many liters of epoxy for a 1 square meter floor at 3mm thick?

1 m² × 0.003 m = 0.003 m³ = 3 liters per coat. For two coats on normal concrete with a 15% porosity factor: 3 L × 2 × 1.15 ≈ 6.9 liters. Add 10% waste buffer = approximately 7.6 liters total.

How do I convert fluid ounces to liters for epoxy?

Multiply fluid ounces by 0.02957 to get liters. For example: 128 fl oz × 0.02957 = 3.785 liters (1 gallon). Or divide fl oz by 33.81 to get liters directly.

Epoxy Resin Calculator in Liters — Metric Volume Guide

Q: How do I calculate liters of epoxy resin needed?

Measure your project in centimeters: length × width × depth = cubic centimeters (cm³). Since 1 mL = 1 cm³, the result is already in milliliters. Divide by 1000 to get liters. Add your waste buffer (10–15%) to the final figure.

Q: How many liters are in a standard epoxy kit?

Common kit sizes: 500 mL (0.5 L), 1 L, 3 L, 5 L, 10 L, 20 L. For river tables and large floors, 5–20 L kits are most cost-effective. Always buy 10–15% more than your calculated volume.

Working in metric? This guide explains how to calculate epoxy resin volume in liters and milliliters for any project. You'll find the metric formula, coverage tables in m², and a quick-reference chart for common project sizes — plus a link to the free calculator with a built-in metric mode.

📐 Metric Formula

How to Calculate Epoxy Volume in Liters

The metric calculation is actually simpler than imperial because cubic centimeters equal milliliters directly (no conversion factor needed):

Volume (mL) = Length (cm) × Width (cm) × Depth (cm)
Volume (L) = Volume (mL) ÷ 1000
Total with buffer = Volume (L) × (1 + waste buffer %)

For floor coatings measured in meters, convert to cm first (1 m = 100 cm), or use:

Volume (L) = Area (m²) × Thickness (mm) × porosity factor

Example: A 200 cm × 20 cm × 4 cm river channel at 85% void fill:
200 × 20 × 4 × 0.85 = 13,600 mL = 13.6 L net. Add 10% buffer = 15 L total.

📊 Floor Coverage in Liters per m²

How Many Liters Per Square Meter?

Coverage depends on coat thickness. These figures are per coat on smooth concrete (multiply by your porosity factor for rough surfaces):

Coat Thickness	Liters per m² (per coat)	Liters per 10 m²
0.5 mm (seal coat)	0.5 L	5 L
1 mm	1.0 L	10 L
1.5 mm (standard)	1.5 L	15 L
2 mm	2.0 L	20 L
3 mm (self-leveling)	3.0 L	30 L
6 mm (thick pour)	6.0 L	60 L

Porous concrete absorbs 15–30% more on the first coat. Very rough or old concrete can absorb up to 50% more. Always apply a seal coat first on porous surfaces.

Quick Reference — Liters by Project Size

These estimates use 85% void fill for river tables, 1.5 mm coat thickness for floors, and a 10% waste buffer throughout:

Project	Size	Net (L)	With 10% Buffer
River table	180 × 20 × 4 cm	12.2 L	13.5 L
River table	220 × 25 × 5 cm	23.4 L	25.8 L
Floor (1 coat)	10 m² × 1.5 mm	15 L	16.5 L
Floor (2 coats)	20 m² × 1.5 mm	60 L	66 L

Frequently Asked Questions

How do I calculate liters of epoxy resin needed?

Measure in centimeters: length × width × depth = cm³ = mL. Divide by 1000 for liters. Apply your void fill or porosity factor, then add a 10–15% waste buffer. The calculator's metric mode does this automatically.

How many liters for a 1 m² floor at 3 mm thick?

1 m² × 3 mm = 3 liters per coat on smooth concrete. For two coats on normal concrete (1.15× porosity): 3 × 2 × 1.15 = 6.9 L net. Add 10% buffer = ~7.6 liters. Very porous surfaces need up to 50% more on the first coat.

How many liters are in a standard epoxy kit?

Common sizes: 500 mL, 1 L, 3 L, 5 L, 10 L, 20 L. River table and large floor projects typically use 5–20 L kits for better value. Always calculate first, then buy the nearest kit size above your total (plus at least one spare).

How do I convert fluid ounces to liters?

Multiply fluid ounces by 0.02957 to get liters. Examples: 32 fl oz × 0.02957 = 0.946 L; 128 fl oz (1 gallon) = 3.785 L. Or use the conversion table above for quick reference.
