Application Analysis
Example Calculations
Example 1: 8ft × 4ft Table
Dimensions: 8 ft × 4 ft × 1 inch thick
Converted: 96 in × 48 in × 1 in
Volume: 96 × 48 × 1 = 4,608 cubic inches
Result: 19.95 gallons or 2,552 fl oz
Example 2: Round Table
Dimensions: 32 inch diameter × 2 inch thick
Radius: 16 inches
Volume: π × 16² × 2 = 1,608.5 cubic inches
Result: 6.96 gallons or 891.3 fl oz
Example 3: Small Craft Project
Dimensions: 24 in × 24 in × 1 inch thick
Volume: 24 × 24 × 1 = 576 cubic inches
Result: 2.49 gallons or 319.7 fl oz
Epoxy Types
Table Top Epoxy
High-gloss finish
1/8" to 1/4" thickness
Floor Coating
High-durability formula
1/16" to 1/8" thickness
Art Resin
UV-resistant, crystal clear
Up to 1/4" per pour
Thickness Guidelines
Thin Coat (1/16" - 1/8")
• Floor coatings
• Protective layers
• Light-duty surfaces
Medium Coat (1/8" - 1/4")
• Table tops
• Countertops
• Art projects
Thick Coat (1/4" - 1/2")
• River tables
• Deep embedding
• Special projects
Application Tips
Clean surface thoroughly before application
Mix in 2:1 ratio (resin:hardener) by volume
Work in 70-80°F temperature range
Buy 10-15% extra for waste and touch-ups
Understanding Epoxy Calculations
What is Epoxy Resin?
Epoxy resin is a liquid adhesive that becomes solid when mixed with a hardener in a 2:1 ratio. It provides strength, durability, and waterproofing for various materials including wood, metal, plastic, glass, and ceramic.
Why Accurate Calculations Matter
- •Ensures proper coverage and thickness
- •Prevents waste of expensive materials
- •Maintains proper mixing ratios for curing
- •Helps plan project timeline and costs
Calculation Formulas
Rectangular:
Volume = Length × Width × Thickness
Circular:
Volume = π × (Diameter/2)² × Thickness
Mixing Ratio:
Resin: Hardener = 2:1
- π: Mathematical constant (≈3.14159)
- Radius: Half of the diameter
- Thickness: Desired coating depth
- 2:1 Ratio: Standard epoxy mixing ratio
Note: Epoxy typically requires several days to fully cure. Clean the surface thoroughly as epoxy doesn't bond well with greasy surfaces.
