Sulfuric acid is one of the most aggressive and widely used industrial chemicals. It is vital to industries like chemical processing, battery manufacturing, metal treatment, and water treatment plants. However, sulfuric acid storage tanks, containment areas, and processing zones face constant threats from acid spills, splashes, and chemical vapors, which can rapidly corrode concrete and steel surfaces.
Facilities that handle sulfuric acid (H₂SO₄) require a high-performance chemical-resistant coating to prevent substrate deterioration, ensure environmental compliance, and protect worker safety.
This is where Epoxy.com Product #633 Novolac Epoxy Coating excels.
Why Sulfuric Acid is So Destructive
Sulfuric acid is extremely corrosive and reacts aggressively with:
• Concrete – Dissolving calcium hydroxide, weakening the slab.
• Steel – Accelerating rust and structural degradation.
• Grouts & Mortars – Leading to surface erosion and joint failures.
Even diluted sulfuric acid (e.g., battery acid) can cause permanent surface damage if not contained properly.
Epoxy.com Product #633: Built for Sulfuric Acid Protection
Epoxy.com Product #633 is a 100% solids Novolac epoxy coating engineered specifically for chemical containment areas exposed to strong acids like sulfuric acid. It forms an impermeable, highly chemical-resistant barrier, making it ideal for:
✔ Sulfuric Acid Storage Tanks & Secondary Containment
✔ Chemical Processing Floors
✔ Battery Charging Areas
✔ Drainage Systems Handling Acidic Waste
✔ Acid Leak Containment Trenches

Key Benefits of Epoxy.com Product #633
1. Superior Acid Resistance
Novolac epoxy chemistry offers outstanding resistance to concentrated sulfuric acid, including solutions up to 98% concentration.
This prevents surface erosion and chemical penetration, ensuring long-term protection even in constant exposure environments.
2. Long-Term Durability
• Protects Concrete & Steel from both splash exposure and chemical immersion.
• Abrasion-resistant surface holds up under forklift traffic, chemical drums, and industrial equipment.
• Prevents cracks and degradation often seen with standard epoxy coatings when exposed to acid attacks.
3. Seamless & Non-Porous Surface
Product #633 creates a seamless protective layer that seals the substrate.
This prevents acid infiltration into underlying concrete, which can lead to subsurface corrosion and costly structural repairs.
4. Easy Application Over Concrete and Steel
Product #633 can be applied to new or existing floors, including:
✔ Concrete containment areas
✔ Steel tank bases
✔ Repairing acid-damaged surfaces
Recommended System for Sulfuric Acid Environment
Step 1: Surface Preparation
• Concrete: Shot-blast or diamond grind to create a clean, rough surface.
• Steel: Sandblast to SSPC-SP10 near-white metal finish.
Step 2: Priming
Apply Epoxy.com Product #12 or Product #899 Epoxy Primer to seal the substrate and enhance adhesion.
Step 3: Application of Epoxy.com Product #633
• First Coat: Roll or squeegee at 160-200 sq. ft. per gallon.
• Second Coat: Repeat application to build chemical-resistant thickness (total thickness: 16-20 mils).
Optional: Broadcast Aggregate for Slip Resistance
For areas with heavy traffic or wet conditions, broadcast silica sand or aluminum oxide into the first coat for enhanced traction.
Real-World Applications
Epoxy.com Product #633 is trusted in:
• Battery Manufacturing Plants – Protecting floors from battery acid leaks.
• Water Treatment Facilities – Shielding containment areas from sulfuric acid dosing systems.
• Metal Finishing Plants – Protecting work areas where acid baths are common.
Compliance & Safety
Product #633 is designed to meet regulatory requirements for chemical containment in:
• EPA Secondary Containment (40 CFR 264.175)
• USDA Accepted for Use in Food Plants
Proper containment with acid-resistant coatings also reduces liability risks and ensures compliance with hazardous materials regulations.
