Facebook← Back to Which resin bound gravel should I choose for courtyards?
Laying resin bound gravel over an existing concrete courtyard base is a practical way to upgrade old outdoor surfaces. With the right products and preparation, you can achieve a robust, attractive, and water-permeable finish.
Preparing an Existing Concrete Base
It is essential to make sure your concrete base is structurally sound, clean, and free of movement or major cracks. Begin by sweeping to remove debris and pressure-washing if any dirt or moss is present. Address any cracks with suitable concrete repair materials and allow the surface to completely dry before proceeding. A primer, such as Resinstone one-component methacrylic resin, can be applied to improve adhesion and help seal the base—especially valuable on older or slightly dusty concrete.
Choosing the Right Resin System
For resin-bound courtyards, the most reliable results come from using a full system where pebbles or decorative aggregates are mixed with a suitable resin binder before laying. Products like the Flowstone Complete Permeable Floor Kit provide everything needed for mixing and installing a permeable, decorative finish over your prepared concrete. If you choose coloured stones, opt for a UV-stable epoxy such as the Trasparente epoxy binder to help preserve the aggregate’s appearance.
When This Matters
This approach is ideal if you want to revitalise a tired concrete courtyard without full demolition works and desire a low-maintenance, decorative surface with good drainage. It’s particularly relevant in urban or garden settings where water run-off must be controlled.
