Why Standard Epoxy Fails Against Chemicals
Acid and chemical spills can rapidly damage any concrete floor lacking proper protection. The image below shows the difference: the left side is coated with a standard "heavy-duty" 100% solids epoxy, while the right side uses ArmorGarage Acid Shield.
The standard epoxy side has developed yellowing and exposed aggregate as caustic chemicals eat away at the concrete. In contrast, the Acid Shield system remains unaffected under the same exposure conditions.
If left improperly protected, the damaged slab will eventually require removal and replacement β a far more costly outcome than coating it correctly from the start.
While Acid Shield has a slightly higher upfront cost, it is significantly more economical long-term by eliminating downtime, recoating, and slab replacement.
Acid Shield Epoxy Systems
We've done extensive research and field testing to ensure that when you choose an ArmorGarage Acid Shield epoxy coating, you're getting the highest corrosion protection possible. ArmorGarage Acid Shield epoxies are 100% Novolac epoxy β not a blend. Using water-based or standard floor epoxies in chemical environments can cause premature floor failure and costly downtime.
As with all our products, these systems are packaged for easy DIY installation β no prior experience needed.
Use the Acid Resistance Guide before buying: chemical exposure duration matters (splash vs long-term immersion). Selecting the wrong system is a guaranteed waste of time and money.
Heavy Duty Acid Shield
Our most popular system because it's resistant to hundreds of acids and chemicals, waterproof, food safe, and withstands thousands of hot caustic wash downs without losing finish.
- 96% solids β’ 25 mils thick
- Shore D 88 (hard hat reference ~75β80)
- 20mg abrasion loss β’ Compressive Strength 9,900 PSI
- Rated for heavy forklift traffic, heavy cart/foot traffic, dropped parts and tools
- Sold as a complete system: Novolac epoxy primer + Novolac epoxy topcoat
Standard Acid Shield
Designed for durability in battery charging areas for electric golf carts and forklifts with a Shore D Hardness rating of 85. Also great for maintenance and storage areas where corrosion risk is present.
AG Mortar Shield
A unique Novolac epoxy mortar for major repairs to floors that have suffered acid corrosion damage and other heavy damage. Use this to rebuild damaged areas before applying an Acid Shield topcoat system.
Epoxy Acid Resistance Guide (300+ chemicals): We compiled a comprehensive guide with over 300 listed chemicals, acids, and hazardous materials showing whether each product is suitable for short-term exposure, long-term immersion, or not recommended.
How To Know How Durable An Epoxy Coating Is
Two specifications tell you everything you need to know about how an epoxy coating will hold up: Abrasion Loss Rating and Shore D Hardness. Buy based on performance specs, not name or price.
Abrasion Loss Rating (Taber C-17)
Abrasion resistance is what keeps epoxy from dulling and wearing off. The Taber C-17 test uses a weighted abrasion wheel at a controlled RPM and duration, then measures how many mgs of material are removed. Lower mg loss = more durable coating.
Residential Grade
Heavy Commercial
Industrial Grade
Military Grade
Shore D Hardness
Shore D measures scratch and scuff resistance. For reference, hard hats measure around 75 Shore D. Any rating near that is excellent β anything above is superior.
Rule of thumb: Always choose a coating rated higher than your traffic demands. Over-rating is safer than under-rating.
Acid Shield Epoxy Questions
What makes Novolac epoxy different from standard epoxy?
Novolac epoxy uses a different resin chemistry that creates a much denser cross-linked molecular structure. This makes it highly resistant to chemical attack, heat, and acid penetration. Standard epoxies β even "heavy duty" ones β break down rapidly under chemical exposure. ArmorGarage Acid Shield products are 100% Novolac, not a blend.
How do I know which Acid Shield system I need?
Download our Acid Resistance Guide (300+ chemicals) and look up the specific chemicals your floor will be exposed to. Exposure duration matters β splash exposure vs long-term immersion require different systems. If you don't see your chemical listed, call us and we'll have a chemist review suitability.
Can I install Acid Shield epoxy myself?
Yes. Like all ArmorGarage systems, Acid Shield products are packaged as complete DIY-friendly kits with clear instructions and all materials included. No prior experience needed. We provide free 7-day/wk phone and email support before, during, and after your project.
What about floors already damaged by acid?
Use our AG Mortar Shield β a Novolac epoxy mortar β to rebuild and repair areas that have suffered acid corrosion damage before applying the Acid Shield topcoat system. This restores the slab profile and ensures proper adhesion.
Is Acid Shield food safe?
Yes. The Heavy Duty Acid Shield system is food safe, waterproof, and withstands thousands of hot caustic wash downs without losing finish β making it ideal for breweries, food prep facilities, commercial kitchens, and food production floors.
