Before you begin any resin floor project, it’s essential to understand whether your existing substrate is suitable. Getting compatibility right avoids future issues with peeling, lifting, and adhesion.
Why Substrate Compatibility Matters
Every resin system relies on a strong grip between the resin and the underlying floor. Not all surfaces behave the same: while concrete, ceramic tiles, screeds and timber are generally suitable, some substrates might not create a secure bond. Applying resin to the wrong substrate can result in failed adhesion, causing cracks or blisters that are tricky and expensive to repair.
How to Test and Prepare Your Floor
- Identify your substrate: Commonly, resin is best applied over clean, dry, and stable surfaces like concrete or timber. Avoid surfaces that are crumbly, oil-contaminated, or damp.
- Check stability: Ensure the floor is sound – cracks, loose tiles, or movement will all compromise results.
- Apply the right primer: Use a specialist floor primer, such as Epoxyprimer, to maximise bonding on compatible surfaces.
Follow the primer product guidance closely for optimal coverage and drying times.
When Substrate Compatibility Matters Most
Ensuring substrate compatibility is especially important if you’re resurfacing older floors, switching between very different materials (like from tiles to concrete), or installing floors in high-traffic areas where durability is critical.
