AndCoat HB LT is a solvent-free, high-build two-pack epoxy coating formulated for use in colder conditions. Designed to cure at lower temperatures, it provides the same outstanding durability, adhesion and chemical resistance as standard AndCoat HB, but with extended working times that make it suitable for winter application.

This coating delivers a smooth, gloss finish with exceptional resistance to water, oils, fuels and many chemicals. It is ideal for use on concrete floors, steelwork, bunds, tank linings and other industrial surfaces where both high performance and cold-weather application are required.

Surface Preparation

For best results, substrates must be sound, clean and free from contaminants:

• Concrete & Masonry: Minimum 28 days cure, dry and structurally sound. Remove laitance, dust, oil, grease and other contaminants by vacuum blasting or grinding. Repair surface defects before application.
• Steel: Blast clean to SA 2½ (ISO 8501-1) or equivalent, producing a sharp profile. Coat immediately after preparation to avoid flash rusting. If blasting is not possible, mechanically prepare to St3 standard.
• Previously Coated Surfaces: Remove any unsound coatings. Abrade sound coatings to provide a key.
• All surfaces must be clean, dry and free from moisture before application.

Directions for Use / Application

• Mixing: Add Hardener to Base in the specified 4:1 ratio. Mix mechanically with a slow-speed drill and paddle until uniform. Only mix what can be applied within the pot life.

• Application Methods: Suitable for brush, roller or airless spray. Apply in even coats, avoiding puddling.

• Environmental Conditions:

  • Substrate & ambient temp: Min 5°C (up to 20°C)

  • Surface must be at least 3°C above dew point

  • Maximum RH: 85%

• Overcoating: Recoat between 16–72 hours at 10°C. If maximum interval is exceeded, abrade to provide a key.

• Curing: Full chemical cure achieved after 7–10 days at 10°C.

• Cleaning: Use AndCoat Thinner or suitable solvent to clean tools and equipment immediately after use.

• Storage: Keep in original unopened containers 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.
