Epoxy Moisture Barrier Primer for Damp Mineral Substrates

Concerned about residual moisture damaging your floor system?
This two-component, solvent-free epoxy primer is designed to act as an effective moisture barrier on clean, dense and waterproof mineral surfaces, helping to protect resin flooring systems from moisture-related failure.

It can be safely applied on substrates with a residual moisture content between 3% and 6%, making it a practical solution for renovation projects where fully dry conditions are difficult to achieve.

Why use this moisture-tolerant epoxy primer?

• Reliable moisture control
  Forms a tight sealing layer that reduces moisture vapour transmission, protecting subsequent coatings from blistering and loss of adhesion.

• Solvent-free and low odour
  Safer to apply and more comfortable for indoor use, especially in enclosed commercial or industrial environments.

• Designed for demanding renovation conditions
  Ideal when working on concrete or stone surfaces that cannot fully dry within project timelines.

• Two-layer system for maximum sealing performance
  Applied in two coats to ensure full coverage and a consistent moisture barrier across the entire surface.

Where is it suitable?

This epoxy moisture barrier primer is recommended for:

• Clean, waterproof concrete floors

• Dense stone or mineral substrates

• Commercial and industrial refurbishment projects

• Areas where residual moisture is present but controlled

⚠️ Important: This product is not suitable for substrates with rising damp or active moisture ingress.

Application guidance

1. Surface preparation
   Ensure the surface is clean, sound, waterproof and free from contaminants.

2. Mixing
   Mix both components thoroughly until a uniform consistency is achieved.

3. Primer application
   Apply the first coat evenly and allow it to cure before applying the second layer to achieve a complete seal.

4. Overcoating
   Once cured, the surface is ready for compatible epoxy or polyurethane flooring systems.
