02 / STEP-BY-STEP JOBSITE EXECUTION PROTOCOL
- Step 1 — Grind to CSP 2–3 & Seal Outgassing Pores: Diamond grind the slab to remove curing compounds and laitance (read our CSP 2–3 Grinding Guide). Never pour a 35-mil metallic coat onto unprimed concrete—air trapped in open pores will expand and blow craters through your metallic design. Lock dry slabs with PRIMER 49 or damp slabs up to 25 lbs MVER with MVB 49.
- Step 2 — Pre-Blend 150g Mica Jars into Part A First: Pour 2 gallons of EPOXY 49 Part A (Green-Banded Resin) into a clean mixing pail and blend in two 150g jars (300g total) of Epoxy49 Metallic Mica Pigment ($14.99/jar) at 350 RPM for 90 seconds. Once pre-dispersed, your pigmented Part A has unlimited shelf stability until catalyzed.
- Step 3 — Catalyze 2A:1B & Ribbon-Pour Immediately: Add 1 gallon of EPOXY 49 Part B (Orange-Banded Hardener), mix with a spiral Jiffy blade at 350 RPM for exactly 3 minutes (scraping sidewalls and bottom), and immediately empty the entire 3-gallon batch onto the primed floor in serpentine S-ribbons.
- Step 4 — 70 / 20 / 10 Marbling & 91% IPA Mist: Gauge-rake or 18" Magic-Trowel your primary 70% color across the floor, pour contrasting 20% secondary and 10% highlight ribbons along natural diagonal stone fracture lines, gently loop with a 3/8" lint-free nap on spiked shoes, and mist 91% Isopropyl Alcohol within 20 minutes to open 3D crater cells.
- Step 5 — Seal with 1A:1B POLYASPARTIC 49 Silver F-Tins: Once EPOXY 49 is tack-free (8–24 hours at 72°F), mix 1 Part A + 1 Part B of POLYASPARTIC 49 for 2 minutes at 350 RPM and cross-roll a crisp 6–8 wet mil crystal armor coat.

POLYASPARTIC 49 ($219.00)04 / FREQUENTLY ASKED METALLIC RECIPE QUESTIONS
How much metallic pigment powder do you mix per 3-Gallon Kit of EPOXY 49?
Dose exactly 1 jar (150g) of Epoxy49 Metallic Mica Pigment per 1 gallon of Part A resin—which equals 2 jars (300g total) per 3-Gallon EPOXY 49 Kit (2 Gal Part A + 1 Gal Part B). Always pre-blend the mica powder thoroughly into Part A resin BEFORE adding Part B hardener so you never waste pot life dispersing dry pigment.
What spread rate (sq ft per gallon) gives true 3D metallic movement without bare spots?
Pour 100% solids EPOXY 49 at 42–50 sq ft per mixed gallon—which equals 125–150 sq ft per 3-Gallon Kit (32–40 wet mils). Rolling metallic epoxy thinner than 20 wet mils starves the mica platelets of liquid suspension depth and prevents organic convection cells from forming.
Why must you use 91% or 99% Isopropyl Alcohol instead of 70% rubbing alcohol for marbling?
Standard 70% drugstore rubbing alcohol contains 30% water. Spraying water droplets onto uncured 100% solids cycloaliphatic epoxy causes cloudy white carbamate ("amine blush") rings and sticky uncured spots. Always use 91% or 99% anhydrous Isopropyl Alcohol (IPA) in a coarse pump sprayer within 20 minutes of ribbon placement.
Do metallic epoxy garage floors require a POLYASPARTIC 49 topcoat?
Yes. High-gloss metallic epoxy showcases mirror depth, so protecting it within the 8–24 hour tack-free window with a 6–8 wet mil coat of POLYASPARTIC 49 (1A:1B silver metal F-tins) locks in UV non-yellowing stability, <25 mg Taber scratch defense, and 140°F hot-tire immunity.
