Can I Repair Surface Defects After Curing?

← Back to How to apply resin to the terrace waterproofing membrane?

Small imperfections may appear after your resin terrace surface cures, but most can be successfully repaired. Restoring a smooth, seamless finish is possible with the right approach and a bit of care.

How to Address Surface Irregularities

If you notice minor bumps or shallow dips after the curing process, these can often be corrected by careful sanding to level out roughness. Once sanded, apply a fresh layer of resin or a resin-aggregate mixture to fill and smooth the defect. It’s important to allow this patch to cure as per the product instructions before resuming use.

Choosing the Right Products for Repair

Repairs should match the original resin and aggregate for the best aesthetic and performance. For example, the Flowstone Complete Kit provides compatible materials for patching permeable floors, while the Trasparente Epoxy Binder is ideal for coloured aggregate surfaces. Select a binder that suits your original flooring’s colour and aggregate type for an even finish.

When Surface Repair Matters Most

• Safety: Smooth out sharp edges or trip hazards created by uneven surfaces.
• Water Drainage: Restorative repairs help maintain the terrace’s ability to manage rainwater, avoiding puddles or water damage.
• Appearance: Prompt touch-ups keep your terrace looking fresh and inviting for longer.
