Installed price for garage and basement floors: $4–$10 per sq ft for professional epoxy, with DIY kits, flake, metallic, and polyaspartic compared.

Next Step
Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Choose the calculator that matches the real job
The fastest way to get a trustworthy estimate is to start from the actual project type. River tables, deep pours, coatings, floor jobs, and void fills do not share the same measurement logic or product constraints.
Pour volume for regular shapes, with worked examples, depth limits, and estimates in gallons or liters.
Use quick mode or segment mode for live-edge rivers, plus seepage, seal-coat, and cost planning.
Plan thick casts with layer guidance, staged lifts, and deep-pour product fit.
Use surface area and coat thickness for tabletops, bar tops, and countertop finishes.
Pressure-test the budget after you know the resin quantity, waste factor, and kit price.
Estimate cracks, knots, and small cavity fills where ounces and milliliters matter.
Gallons and kits for a garage or basement floor from square footage, coats, and kit coverage.
Gallons and kits for two coats on a 20 × 20 to 24 × 24 ft garage floor.
Pounds of vinyl flake and boxes for a full or partial broadcast floor.
Plan silicone molds, craft cavities, cube, cylinder, and sphere casts.
Calculators for molds and small pieces
Coasters, dice, and shaped molds need milliliters, not gallons. Start from the shape you are filling and the number of pieces.
Round or square coasters with set totals in mL.
Cubic blanks or a known mold capacity, per die and per set.
Columns, tumbler inserts, and round molds by diameter and height.
Ball and dome molds by inside diameter.
Block and cube molds; doubling the side needs eight times the resin.
Small batches for pendants and earrings from a known cavity size.

Popular decisions people make before buying epoxy
Most buyers need more than a formula: how much extra to buy, how to measure an irregular river, and when a deep-pour resin is required instead of a top coat.
Short answer first, then the right calculator path.
Estimate quantity, waste, and kit count for a live-edge river build.
A practical segment method for irregular channels.
Know when the resin class is the real bottleneck.
Decide how much extra resin to buy and why.
Typical thickness by job and square feet per gallon at each thickness.
Compare price, cure time, and yellowing before you take a floor quote.
Mils and mm for each floor system, from DIY kits to troweled mortar.
Plan Part A / Part B and batch size after the quantity is known.
Answer coverage by thickness before choosing a kit.
Understand why a gallon covers different areas at different thicknesses.
Match calculated quantity to real gallons, liters, and kit listings.
Decide whether the first coat and finish coat need separate estimates.
