Resurfacing old or damaged concrete with the Flowstone resin-bound system can revitalise outdoor spaces, provided the right preparation steps are taken. Here’s what you need to know to ensure a steady, long-lasting result.
Assessing & Repairing the Concrete Base
Before using the Flowstone kit, closely inspect your existing concrete. The surface must be structurally sound—large areas of crumbling, unstable or deeply cracked concrete need attention. Clean thoroughly to remove loose material, oil, dirt or moss. For minor localized damage, well-bonded repair mortars can be used to infill and smooth out depressions or cracks, creating a level and secure foundation for resin application.
- Remove all debris and loose patches.
- Patch cracks and unstable areas before applying resin systems.
Improving Bond with Primers
A quality primer helps resin systems like Flowstone adhere more effectively, especially on porous or patched concrete. Using an epoxy primer such as Epoxyprimer can reduce absorption and ensure a consistent, durable bond between the old concrete and the new resin-bound layer. Follow the recommended curing and application instructions for the best results.
When This Matters Most
Applying Flowstone on previously weathered or repaired concrete is a great way to upgrade tired driveways or patios without worrying about removing old slabs. However, careful surface preparation is crucial—overlooking repairs or proper cleaning can lead to performance issues or premature failure.
