DESCRIPTION
EF-155 lets a crew build a complete epoxy floor in a single day.
EF-155 is a super-fast-curing, 2-component, 100% solids, self-leveling, high-build epoxy floor coating. At 68°F you can recoat in as little as 2-4 hours and return foot traffic in 6-8, so a multi-day floor system fits into one shift. It also cures in low temperatures down to a 32°F (0°C) substrate for cold-weather work. Note that the minimum application temperature is 50°F (10°C) per the TDS; the 32°F figure refers to the substrate service temperature.
That speed makes EF-155 a strong fast base for metallic and decorative flake floors. Pour the clear base, then broadcast flake or top-coat the same day instead of waiting overnight. It also works as a high-build primer over concrete and existing epoxy, and as the binder for patching and resurfacing aggressive industrial floors. The modified aliphatic chemistry reduces water spotting and amine blushing for a cleaner, more consistent cure.
The fast set does not cost you toughness. EF-155 delivers 6,200 psi compressive strength, 5,500 psi tensile, 80-85 Shore D hardness, 0.07 g Taber abrasion loss, and a 93 GU gloss. It is solvent-free at <50 g/L VOC (LEED v4 low-emitting), meets CFIA and USDA requirements for indirect food contact, and is available in six stock colors. Because the fast set leaves a short working window, mix only what you can place in 10-15 minutes, and finish with an Everflow UV-stable polyaspartic or urethane for color and outdoor durability.
Key Features & Benefits
- Super-Fast Cure: Recoat in 2-4 hours and return foot traffic in 6-8 at 68°F, so a full floor system goes down in a single day.
- Cold-Weather Capable: Rated to a 32°F (0°C) substrate; apply at 50°F (10°C) or warmer per the TDS to keep winter and tight-deadline jobs on schedule.
- Built for Metallic & Flake Systems: The clear, fast-setting base lets you broadcast flake or top-coat the same day instead of waiting overnight.
- 100% Solids, Self-Leveling: Seamless, high-build film with no shrinkage. Also serves as a primer and as a patching or resurfacing binder.
- Tough Mechanicals: 6,200 psi compressive, 5,500 psi tensile, 80-85 Shore D, and 0.07 g Taber abrasion loss.
- Low-VOC & Food-Plant Rated: <50 g/L VOC, LEED v4 low-emitting; meets CFIA and USDA requirements for indirect food contact.
- 6 Stock Colors, Top-Coatable: Clear, white, beige, black, light grey, and medium grey. Finish with an Everflow polyaspartic or urethane.
