Why This Product
- ✓ UV-stable topcoat shields the aggregate binder resin from the primary cause of exterior epoxy aging
- ✓ Seals open aggregate surface against chlorine, fertilizers, oil, and chemical staining from above
- ✓ Transforms porous washed stone into a cleanable sealed surface — pressure-wash without concern
- ✓ Two-coat system adds measurable chemical and abrasion resistance over the base aggregate layer
- ✓ Enhances and unifies color consistency across the aggregate surface for a premium finished appearance
- ✓ Near-essential in high-UV climates (Arizona, Florida, Texas) for full system lifespan

Top Coat Varnish (Optional) - Quartz Epoxy Outdoor Washed Stone
The Quartz Epoxy Outdoor Washed Stone Top Coat Varnish is an optional protective seal designed to enhance the durability, appearance, and longevity of washed stone and quartz epoxy surfaces.
This clear varnish provides a strong protective layer that helps lock in aggregates, reduce surface wear, and improve resistance to weather, UV exposure, moisture, and staining. Ideal for outdoor applications such as patios, walkways, pool decks, balconies, and driveways, it adds a subtle satin sheen while preserving the natural stone look.
The top coat is easy to apply and is recommended for high-traffic or exposed areas where additional protection is desired.

Not paint. Not a coating. A permanent floor system.
Most garage floor products you see at hardware stores are 1-part acrylic or latex epoxy paints. They look like epoxy, they're marketed like epoxy, but they sit on top of concrete without a true chemical bond. Hot tire pickup, oil spills, and foot traffic degrade them within 1–3 years.
Our system is a true 2-part bisphenol A epoxy resin that chemically cross-links with the concrete surface on a molecular level. It doesn't just sit on top — it bonds into the concrete profile. That's why it lasts 10–20 years under conditions that destroy paint-based coatings in a season.
Quartz Sand Epoxy vs. Everything Else

- ✅ True 2-part system
- ✅ Chemical concrete bond
- ✅ Quartz texture + grip
- ✅ 10–20 yr lifespan
- ✅ DIY-ready kit format
- ✅ $2.49/sq ft value
Why the quartz aggregate makes all the difference
The silica quartz sand isn't just decorative. When it embeds into the wet epoxy, it:
- ●Adds hardness and impact resistance that plain epoxy can't achieve alone
- ●Creates a natural non-slip texture — safer than smooth epoxy or polished concrete
- ●Prevents micro-cracking from thermal expansion and contraction cycles
- ●Gives the floor its signature stone-like depth and texture that paint can never replicate

Surface Preparation (Most Important Step)
Clean thoroughly — remove all grease, oil, dust, and contaminants with a concrete degreaser. Repair cracks and holes. Grind or shot-blast the surface to open the pores and create a mechanical profile for bonding. A properly prepped floor bonds for 20+ years. A rushed prep fails in 12–18 months regardless of product quality.
⏱ 2–4 HoursPrimer (Recommended for Older Concrete)
Apply primer to porous or previously coated surfaces. Primer fills micro-pores, dramatically improves adhesion, and prevents off-gassing bubbles. Allow full cure before proceeding. Especially important on concrete older than 5 years.
⏱ Per product labelMix Part A + Part B
Combine at the exact ratio on the label using a drill and paddle mixer. Mix thoroughly for 2–3 minutes — unmixed streaks will not cure correctly. You have 20–30 minutes of working time (pot life). Work in manageable sections for larger floors.
⏱ 20–30 min per kitPour, Spread, and De-Foam
Pour the mixed epoxy onto the floor and spread with a 22" squeegee to achieve an even layer. Immediately follow with a spiked de-foaming roller — pass over the surface multiple times in overlapping rows to release trapped air bubbles and embed the quartz aggregate.
⏱ 30–60 min per areaCure and Enjoy
Allow to cure in a dry, ventilated space. Walkable in ~24 hours, light use after 48 hours, full cure at 72 hours (68°F+). Avoid water for 7 days, heavy loads for 5 days. After full cure, your floor is chemical-resistant, easy to clean, and built to last decades.

"We did our entire restaurant floor — 1,800 sq ft. The self-leveling system made it manageable for our crew. Health inspection passed with flying colors. The slip resistance is exactly what we needed in a commercial kitchen."
"As a flooring contractor, I've tried a lot of epoxy systems. This is the easiest to install I've found — and the finish quality is genuinely commercial-grade. My clients love it. I order in bulk every month."
"Completely transformed our 3-car garage over a weekend. The instructions were clear and the team was available by phone when I had questions. Looks absolutely incredible and held up perfectly after 6 months."
"Our warehouse needed something that could handle forklifts, spills, and constant foot traffic. Eight months in — zero issues. No peeling, no cracking. Exactly what was promised. Would order again without hesitation."
"The bulk pricing program saved us thousands on a 12-location retail rollout. Responsive team, fast shipping, and consistent quality across every location. This is our go-to for all future build-outs."
"Fast shipping, great phone support, beautiful result. I miscalculated and ordered too few kits — they had more shipped same day. That kind of service is why I keep coming back. Five stars all the way."
