GARAGE FLOOR EPOXY KIT BUYING GUIDE: SIZING, WET-MIL MATH & PART A/B CONTAINERS

Running 2 gallons short mid-pour ruins a seamless floor—while buying watered-down 45%-solids retail kits leaves only 2.5 mils of film on your slab. Use this engineering buying guide to size 1-Car (250 sq ft), 2-Car (500 sq ft), and 3-Car (750 sq ft) commercial garage systems down to the exact Part A bucket, Part B hardener, and silver metal topcoat tin.

01 / 1-CAR, 2-CAR & 3-CAR GARAGE KIT SIZING & PRICING MATRIX

Always measure wall-to-wall square footage plus 10% waste/stem-wall allowance if coating vertical 4-inch concrete stem walls. Below is our exact container count comparing Full Heavy-Build Ala-Carte Retail Value ($749 / $1,249 / $1,799) against our Manufacturer-Direct Turnkey Bundle Pricing ($349 / $649 / $989):

02 / THE 1,604 MIL-SQ-FT FORMULA: WHY 100% SOLIDS WET MILS = DRY MILS

In coatings engineering, 1 US gallon = 231 cubic inches = 1,604 sq ft at 1.0 wet mil. Multiply that by the percentage of volume solids (ASTM D2697) to find how much resin actually stays on your garage floor after curing:

  • 42% Solids Retail Waterborne Kit (1 Gal @ 250 sq ft): 1,604 ÷ 250 = 6.4 wet mils × 0.42 solids =only 2.7 dry mils left on the floor (thinner than a human hair!).
  • 100% Solids EPOXY 49 (3-Gal Kit @ 150 sq ft Metallic Build): (3 × 1,604) ÷ 150 = 32.1 wet mils × 1.00 solids =32.1 cured dry mils of zero-shrinkage structural armor—plus 6–8 mils of Primer/MVB and 6–8 mils of POLYASPARTIC 49 for a 44–56 mil monolithic system.

04 / DIY HOMEOWNER SAVINGS VS. CONTRACTOR GROSS PROFIT ROI

Whether you are a meticulous homeowner upgrading your own 2-car garage or a painting/remodeling pro adding resinous floors to your business (see our Epoxy Business Startup Blueprint), buying manufacturer-direct unlocks massive financial leverage:

  • DIY / Prosumer ROI (500 sq ft 2-Car Garage): Franchise installed quote: $3,800–$4,800. Epoxy49 Turnkey Bundle + grinder rental: ~$850–$1,450 total → Save $2,500–$3,350+ while installing thicker 100% solids chemistry than franchises use.
  • Contractor Crew ROI (500–750 sq ft Garage): Charge $7.00–$9.50/sq ft ($3,500–$6,800), apply volume codes PRO15 (15% OFF 5+ kits), CREW20 (20% OFF 20+ kits), or PALLET25 (25% OFF 50+ kits), and earn $2,500–$4,500+ gross profit per 2-day cycle.

05 / FREQUENTLY ASKED BUYING QUESTIONS

How do you calculate exact wet-mil thickness from gallons of 100% solids epoxy?

One liquid US gallon (231 cubic inches) covers exactly 1,604 sq ft at 1 wet mil (0.001 inch). Because EPOXY 49 is 100% reactive solids (ASTM D2697) with zero water or VOC shrinkage, wet mils equal cured dry mils! Spreading a 3-Gallon Kit (4,812 mil-sq-ft) across 150 sq ft yields 32.1 mils of pure structural build; across 125 sq ft it yields 38.5 mils.

What is the difference between Turnkey Bundle Direct Pricing ($349 / $649 / $989) and Full Heavy-Build Ala-Carte Value ($749 / $1,249 / $1,799)?

Ordering our pre-configured 1-Car (250 sf, $349), 2-Car (500 sf, $649), or 3-Car (750 sf, $989) Turnkey Metallic Bundles directly from Epoxy49 saves 45–50% off individual component retail pricing ($749 for 1-Car, $1,249 for 2-Car with MVB upgrade, and $1,799 for a 3-Car heavy-build 5-kit metallic + dual-coat polyaspartic assembly)—plus includes our Waterproof Wall Checklist and 20-Minute Pre-Pour Virtual Slab Inspection.

Why does POLYASPARTIC 49 ship in 1-Gallon brushed silver metal F-tins while EPOXY 49 ships in 1-Gallon white HDPE split buckets?

Aliphatic polyisocyanate activator (POLYASPARTIC 49 Part B) is moisture-sensitive in storage. Hermetically sealed 1-Gallon metal F-tins prevent ambient humidity permeation during transit and staging, whereas 2A:1B cycloaliphatic resins (PRIMER 49, MVB 49, EPOXY 49) ship in wide-mouth 1-Gallon HDPE split buckets (2 buckets Part A + 1 bucket Part B) for effortless scraping and zero measuring errors.

How much money does a homeowner save—or a contractor earn—on a 500 sq ft 2-car garage?

National franchise installers charge $3,500 to $5,200 ($7.00–$10.40/sq ft) for a 500 sq ft 2-car garage. Prosumer DIYers save $2,500–$4,000+ in a single weekend using our $649–$1,249 commercial kit configurations, while independent flooring contractors net $2,500–$3,800+ in gross profit per job.
