Epoxyprimer – Universal Water-Based Two-Component Epoxy Floor Primer

Preparing your floor with the right primer is essential for a strong, long-lasting permeable resin surface. Epoxyprimer is designed for reliable adhesion and is suitable for a wide variety of stable substrates.

What is Epoxyprimer and Why Use It?

Epoxyprimer is a universal, water-based, two-component epoxy resin primer ideal for prepping floors prior to the application of epoxy resin systems. Its main role is to create a secure bond between your chosen substrate—such as concrete, timber, tiles, or screeds—and the resin layer above. This not only ensures a smoother application but also increases the durability and lifespan of the finished surface.

The water-based formulation is low in odour and suitable for indoor use, making it versatile for both commercial and residential projects.

How to Apply Epoxyprimer Correctly

Before applying, ensure your floor is stable, clean, and dry. Mixing Epoxyprimer requires attention to the specified ratio (typically 100:40 for resin to hardener) to achieve an even, consistent result. Use a roller, brush, or spatula to coat the surface, focusing on achieving uniform coverage. Curing typically takes 24–48 hours depending on site conditions and substrate porosity. A consumption rate of 100–300 g/m² is standard—adjust according to how absorbent your floor is.

For best results on resin-bound permeable floors, such as those using the Flowstone Complete Permeable Floor Kit, take care to follow all preparation steps so that the floor remains breathable and water-draining once finished.

When Epoxyprimer Matters for Permeable Floors

Using a universal epoxy primer is especially important for permeable resin-bound systems installed on concrete or screed bases. It helps prevent de-bonding, provides a stable base, and supports moisture regulation beneath your permeable layer. This is critical in areas with heavy footfall, public spaces, or driveways where maximum long-term durability is needed.
