LQS EPOGUARD 150 – 2-component low solvent, coal tar epoxy coating

ADVANTAGES

• Excellent chemical resistance.
• Outstanding adhesion to most substrates (concrete, steel, etc.).
• Good corrosion resistance.
• Durable waterproof coating in environments with chemicals and waste.
• Suitable for internal and external applications for structures immersed in water for extended periods.

APPLICATIONS

LQS Epoguard 150 is a chemical-resistant coating suitable for use in:

• Wastewater treatment plants
• Bridge piers submerged in water
• Steel or concrete storage tanks
• Oil tanks
• Steel structure protection
• Underground structures, concrete roofs, balconies, terraces

⚠️ Note: LQS Epoguard 150 is not suitable for surfaces in contact with drinking water.

APPLICATION INSTRUCTIONS

Surface Preparation:

Concrete:

• Concrete must be sound and have a minimum compressive strength of 25 N/mm².
• Surface must be clean, dry, and free from contaminants such as dust, oil, grease, old coatings, or curing agents.
• Weak concrete or dusty surfaces must be removed.
• Surface defects such as holes, voids, cracks, or protrusions must be repaired and leveled.

Steel:

• Concrete surrounding steel structures must also be sound with a minimum compressive strength of 25 N/mm².
• For surfaces in contact with chemicals, sandblasting is recommended to remove loose materials and contaminants (rust, scales, etc.), ensuring at least 95% surface cleanliness.
• For surfaces not exposed to chemicals, remove all rust, scales, or foreign materials (until a clean grey surface is visible); follow recommended surface preparation tools and methods.
• Coating must be applied within 3 hours after surface preparation for all metal substrates to avoid contamination or oxidation.

Moisture Check & Primer Application (if required):

• Check surface moisture, ambient humidity, and dew point before application.
• If surface moisture is < 5%, apply LQS Primer SB.
• If surface moisture is ≥ 5%, apply LQS Primer MB (moisture-tolerant epoxy primer).

Mixing Procedure:

• LQS Epoguard 150 is supplied as a two-component system:
  • Part A: Base Resin
  • Part B: Hardener
• Mix Part A thoroughly on its own first. Then add Part B and mix using a mechanical stirrer, moving the mixer up and down during mixing.
• Stir until the mixture is uniform, lump-free, with no sediment or trapped air bubbles.

Coating Application:

• Apply the mixed product using a brush, roller, conventional sprayer, or vacuum spray system.
• Apply the first coat in one consistent direction.
• Apply the second coat in a perpendicular direction to the first, only after the first coat has dried (typically within 24 hours).

SAFETY INFORMATION

• Personal Protection: Wear suitable protective clothing, gloves, and goggles during application.
• Environmental Safety: Do not discharge into water sources or soil.
• Transport: Not classified as hazardous for transport.
• Refer to the Material Safety Data Sheet (MSDS) and other relevant safety documentation for more information.
