← Back to How do you prepare the base for resin flooring?


Choosing the correct primer for your resin flooring project is essential for strong, lasting adhesion—especially as not all floor surfaces require the same approach. Let’s explore the best primer options for various subfloors so you can start your resin floor on the right foot.
Universal Epoxy Primers: A Versatile Solution
For most common base types—including concrete, screed, ceramic tiles, and timber—a universal water-based epoxy primer such as Epoxyprimer offers flexibility and reliable adhesion. Its formulation is suitable for both porous and lightly absorbent surfaces. Application is straightforward—simply use a roller, brush, or spatula. Allow 24 to 48 hours for a full cure before installing the main resin layer. A second coat may be considered for particularly uneven or highly absorbent floors.


When to Use Methacrylic Resin Primers
If you’re working with fresh or ‘green’ concrete that hasn’t fully cured, methacrylic resin primers provide optimum bonding and rapid readiness. Products like Resinstone are specially formulated for these situations, penetrating deeply to seal and protect while allowing breathability. They are ideal when timelines are tight and moisture control is essential.
Practical Considerations for Your Project
- Base condition: Ensure your surface is clean, dry, and free from debris before applying any primer.
- Primer type: Use epoxy primers for stability across different surfaces; switch to methacrylic on newly poured concrete.
- Application: Follow manufacturer guidelines on drying times and layering to achieve best results.

When This Matters Most
Choosing the correct primer makes a critical difference when transitioning between floor types in the same space, working on new builds with uncured concrete, or preparing a mix of surfaces such as timber and tile within one project.
