How much does the floor rise with the “Flowstone” kit?

Typical Floor Level Increase

When using the Flowstone kit, the floor level usually rises by approximately 1.5–2 cm. This small but noticeable increase depends on factors such as the aggregate size and how the mix is laid and compacted. For driveways and areas needing greater durability, a 2 cm layer is common, while patios or footpaths may require only 1.5 cm. Accurately measuring this rise ensures smooth integration with existing thresholds or adjoining surfaces.

Installation Considerations

Proper substrate preparation is essential to achieving a consistent floor height. Start with a stable, clean base—concrete, screed, or compacted sub-base works well. Mix the resin and pebbles thoroughly following kit instructions, then apply in an even layer. Compress and level the mix to the planned thickness, taking care around borders and adjacent paths. For consistently coloured finishes, use non-yellowing polyurethane resin for light stones and a low-yellowing epoxy for coloured stones.

To further enhance adhesion and stability, consider priming the base first with a product like Epoxyprimer – Universal Water-Based Two-Component Epoxy Floor Primer before laying your main layer.

When Does Floor Level Rise Matter Most?

• Adjoining flooring: To ensure accessible and trip-free transitions, match the height with adjoining slabs or paving.
• Drainage: Properly accounting for the added thickness ensures water flows away as designed, particularly in areas close to house thresholds or garden features.
• Door clearance: Be mindful of door swing and ground clearance if a new layer is being added near entrances.
