Benjamin Moore HP4300 100% Solids Epoxy is a two-component, high-build epoxy floor coating from Benjamin Moore's High Performance line. It self-levels to a smooth, heavy-duty gloss finish that fills minor defects and cracks, in one or two coats at 10–15 mils, on interior concrete floors exposed to heavy traffic and aggressive chemicals. Contractors use it on shot-blasted and scarified floors in warehouses, plants and food processing facilities. Each kit is one Part A can in Clear, White, Sandstone or Silver Gray plus one HP4300-90 Part B catalyst, sold separately. CFIA approved; 26.4 g/L VOC.

How to apply
Prep, mix, pour.
- Prep the concrete. Cure new concrete 30 days. Degrease, then acid etch or mechanically abrade to an 80-grit feel. Moisture must read 5% or less.
- Prime with one coat of HP1550 or HP1560 epoxy primer.
- Mix a full kit. Pour all of Part B into Part A and mix with a low-speed drill for 3–5 minutes, scraping the sides. No induction: use it right away.
- Pour and spread a ribbon with a smooth or notched squeegee, working left to right and back.
- Back-roll lightly with a phenolic-core roller and let it self-level. Don't roll into areas laid more than about 10 minutes before.
- Recoat in 12–24 hours (abrade if later). Light traffic after 24 hours, heavy traffic after 72. Clean tools with HP7040.

FAQ
Questions, answered.
What is HP4300 100% Solids Epoxy?
HP4300 is a two-component, 100% solids, high-build epoxy floor coating from Benjamin Moore's High Performance line. It self-levels to a smooth, heavy-duty gloss finish on interior concrete floors that take heavy traffic and aggressive chemicals. It's made for professional contractors experienced with these systems.
Do I need the catalyst?
Yes. Every can of HP4300 Part A needs one HP4300-90 Part B catalyst. The same catalyst works with every colour. Leave the catalyst box ticked next to Add to cart, or use the kit planner, and both go in your cart.
How much does one kit cover?
Benjamin Moore lists 100–150 sq ft per 3.79 L at 10–15 mils. A colour kit mixes to 7.5 L (2 gal), so about 200–300 sq ft per coat; a Clear kit mixes to 6.7 L (1.76 gal), about 176–264 sq ft. Don't spread it thinner than 150 sq ft per gallon. Use the calculator above.
How do I mix it?
Mix full kits only. Pour all of Part B into the Part A can and blend with a low-speed drill mixer for 3–5 minutes, scraping the sides. Keep the speed low so you don't whip in air. There's no induction time: use it right away. The mix ratio is 2:1 for colours and 1.66:1 for Clear, already pre-measured in the kit.
How long is the pot life?
About 30 minutes at 25 °C (77 °F). Warmer temperatures shorten it, so only mix what your crew can spread in that time.
How do I apply it?
Pour a ribbon and spread it with a smooth or notched squeegee, then back-roll with a phenolic-core roller, 9.5–12.7 mm (3/8–1/2 in.) nap, and let it self-level. Don't roll back into areas laid more than about 10 minutes before, or you may see lap marks. Don't thin it.
How long before I can walk or drive on it?
At 25 °C and 50% humidity: touch dry in 6 hours, recoat in 12–24 hours, light industrial use after 24 hours and moderate to heavy industrial use after 72 hours. If you recoat after 24 hours, abrade the first coat.
How do I prepare the concrete?
New concrete must cure 30 days. Clean off oil and grease, then acid etch or mechanically abrade to a profile like 80-grit sandpaper. Moisture must read 5% or less on a meter. Prime with one coat of Benjamin Moore HP1550 or HP1560 epoxy primer.
Can I use it outside or tint it?
No to both. HP4300 is for interior floors only, since it yellows and chalks in sunlight, and it isn't for walls. It comes in Clear, White, Sandstone and Silver Gray; Benjamin Moore says not to tint it.
Is it approved for food plants?
Yes. Benjamin Moore lists HP4300 as approved by the CFIA for use in food processing facilities. It's also CDPH emissions certified and LEED v4 eligible, with 26.4 g/L VOC catalyzed.
