Concrete Coating Systems
We are certified installers of technical, high-performance concrete coatings. We engineer the right system for your specific environment, from Urethane Cement to fast-cure Polyaspartics.
Beyond "One-Size-Fits-All" Epoxy
"Concrete Coating" is a broad term. While epoxy is excellent, it's not always the right answer. As flooring architects, our job is to install the *correct* system for your asset. We are experts in high-performance coatings that solve specific problems.
- Urethane Cement (Food & Beverage): This is the "king" of food processing floors. It is highly resistant to chemicals, acids, and thermal shock (hot-water washdowns) that would cause a standard epoxy to fail. This is the correct system for wineries, breweries, and food plants in Napa or Fresno.
- Polyaspartic Coatings (Fast-Cure): The primary advantage of polyaspartic is speed. It cures in just a few hours, making it the perfect solution for facilities that require a "one-day" install with minimal downtime. It is also UV-stable, so it will never turn yellow, even in direct sunlight.
- Chemical-Resistant Novolac: For battery charging rooms or chemical holding areas, we install Novolac epoxy, which is engineered to withstand 98% sulfuric acid and other harsh solvents.
Our Process: A Bonded, Technical System
A "coating" is only as good as its bond to the concrete. Our installation is a technical process, not a painting job. We diamond-grind or shot-blast 100% of the concrete to create a "profile" (like sandpaper) for the coating to permanently "bite" into. This guarantees a monolithic, bonded system that will not chip, peel, or delaminate.
DIY vs. Pro: The "Epoxy Kit" Trap
A "DIY" 1-part epoxy kit from a hardware store is a thin, water-based paint. It is not a real coating. It is applied to an un-prepped, dirty floor (or an "acid-etched" floor, which is an inferior prep method). It will sit on top of the concrete and peel off in a matter of months, leaving a worse problem than you started with.
Failed "Epoxy Paint" (The "Hobbyist")
This thin "epoxy paint" was rolled on like wall paint. It has no bond and is peeling up under normal traffic.
High-Build Coating System (The "Pro")
This is a 100%-solids, multi-layer system applied to a diamond-ground surface for a permanent, chemical-resistant bond.
★★★★★
"The production floor in our Napa winery takes a beating from chemicals, forklifts, and constant washing. 4RENT installed a high-performance urethane concrete coating that is indestructible and easy to sanitize. Worth every penny."
Concrete Coating FAQs
What is the difference between a Coating and Polishing?
A **Coating** (like epoxy or urethane) is a *topical system* applied *on top* of the concrete. It is seamless, chemical-resistant, and sanitary. **Polishing** is *not* a coating; it is the concrete slab *itself*, which has been ground and densified to a permanent, durable, and low-maintenance shine.
Which coating is best for a Napa winery?
For production floors, barrel rooms, and crush pads, you absolutely need **Urethane Cement**. It is the only system that can handle the combination of thermal shock (hot water), acids (wine, cleaning chemicals), and forklift traffic. Standard epoxy will fail in this environment.
How long does it take to install?
A standard 3-layer epoxy system takes 3-4 days. A fast-cure Polyaspartic system can be installed in a single day. A heavy-duty Urethane Cement system (which is much thicker) typically takes 4-5 days. We will engineer a solution for your downtime.
