Proper surface preparation can make or break a resin-bound drainage floor installation. One important question often asked is whether every crack in the concrete base must be fixed before applying resin. Here’s a practical guide to getting your surface ready for a reliable finish.
Why Fill Every Crack and Hole?
Unrepaired cracks and holes may let moisture seep into the concrete, which undermines the bonding between the resin and the base. Moisture trapped beneath the resin can also cause bubbles, lifting, or long-term damage. Completely repairing defects also creates a smoother, more uniform appearance and supports even curing after the resin is rolled or poured on.
Simple Steps for Concrete Repair
Thoroughly clean the surface to remove dust and debris. Use a suitable concrete repair mortar to fill all cracks and larger voids. Allow these repairs to fully cure—it’s best not to rush this stage. Once cured, the surface can then be primed before resin application. A high-quality primer like Epoxyprimer secures the bond between your concrete base and resin system, helping prevent future peeling or delamination.
- Clean dust, oil, and loose material
- Fill cracks/holes with mortar, smooth level
- Wait for full curing as instructed on the repair product
- Apply a compatible resin primer
When Attention to Repair Matters Most
Filling even small cracks is essential in areas exposed to rain, vehicles, or temperature swings, as these conditions are more likely to force moisture or stress into weak spots. Good preparation is crucial for outdoor resin-bound driveways, patios, or public paths.
