AndCoat HB Solvent Free Epoxy is a high-build, two-pack epoxy coating designed for concrete floors, steel and other demanding substrates where durability and chemical resistance are essential. Its solvent-free formulation provides excellent adhesion, outstanding wear resistance and a tough, gloss finish that stands up to heavy traffic and aggressive environments.

Ideal for use in factories, warehouses, workshops, garages and tank linings, AndCoat HB delivers long-lasting protection against water, oils, fuels, many solvents and general industrial use.

Key Features

• Solvent-free epoxy formulation for low odour and safer application
• High build coating delivering up to 200 microns per coat for maximum protection
• Excellent adhesion to concrete and steel surfaces
• Highly durable and impact resistant for demanding environments
• Resistant to water, chemicals and oils, ideal for industrial and maintenance use
• Suitable for immersion in non-potable water and mild chemical environments
• Hygienic, seamless finish that is easy to clean
• Low odour formula suitable for enclosed or sensitive areas
• Ideal for tank lining, floors and structural surfaces
• Can be used as a one-coat maintenance system over existing epoxy coatings

Surface Preparation

Correct preparation is essential for performance:

• Concrete: Must be at least 28 days old, sound and fully cured. Remove laitance, weak or contaminated surfaces by mechanical means such as vacuum blasting or grinding. Repair surface defects before coating. Ensure the substrate is dry (max 75% RH).
• Steel: Blast clean to minimum SA 2½ (ISO 8501-1) or equivalent, producing a sharp profile. If blasting is not possible, mechanically prepare to St3 standard. Apply immediately after preparation to avoid flash rusting.
• Previously painted surfaces: Remove unsound coatings and thoroughly abrade any remaining coating to provide a key.
• All surfaces must be clean, dry and free from dust, oil, grease or contaminants.

Technical Data

• Type: Two-pack, solvent-free epoxy coating
• Finish: Gloss, high-build
• Colour: Wide range available
• Mix Ratio: 4 parts Base to 1 part Hardener by volume
• Volume Solids: Approx. 100%
• Recommended Film Thickness:

• • Wet: 200–500μm per coat

  • Dry: 200–500μm per coat

• Theoretical Coverage: 4–5m² per litre at 250μm DFT (practical coverage depends on surface and application method)
• Pot Life: 30–40 minutes at 20°C (shorter at higher temperatures)
• Overcoating Interval: Minimum 8 hours, maximum 48 hours @ 20°C
• Full Cure: 5–7 days at 20°C
• Dry Heat Resistance: Up to 60°C
• Chemical Resistance: Excellent against water, mineral oils, fuels, dilute acids, alkalis and many solvents
• VOC: Solvent-free

Directions for Use

• Mixing: Combine the Base and Hardener components in the specified 4:1 ratio. Mix mechanically with a slow-speed drill and paddle until uniform. Do not mix more material than can be applied within the pot life.
• Application Methods: Suitable for brush, roller or airless spray. Apply in even coats, avoiding puddling.
• Environmental Conditions:

  • Temperature: 10–30°C

  • Substrate temperature must be at least 3°C above dew point

  • Relative Humidity: Max 85%

• Overcoating: Apply the next coat after a minimum of 8 hours, and before 48 hours, at 20°C. Beyond this, surface abrasion is required.
• Curing: Allow 5–7 days at 20°C for full chemical cure.
• Cleaning: Clean tools and equipment immediately after use with AndCoat Thinners or suitable solvent.
• Storage: Store in a dry, well-ventilated area between 5°C and 35°C, away from direct sunlight.

Primers & Substrate Preparation

A primer is not typically required for AndCoat HB on sound, non-porous substrates. However, in certain conditions, the correct primer should be used to ensure optimal performance and finish.

• AndPrime– Recommended for porous concrete substrates to improve adhesion and prevent pin-holing, helping achieve a smooth, uniform coating.
• AndCoat DPM (Damp Proof Membrane) – Required where moisture levels are high (above 75% RH) to control moisture and protect the coating system from failure.

Using the appropriate primer ensures maximum adhesion, reduces surface defects, and supports long-term durability of the coating system.
