Essential Tools and Surface Preparation

Superior adhesion starts with a spotless, stable membrane and proper priming. Gather your gloves, mixing buckets, and select appropriate primers and binders for either white or coloured aggregate finishes. Ensure your terrace is dry and weather conditions are stable before beginning application.

Step 1: Inspect and Prepare the Terrace Membrane

Start by thoroughly inspecting your terrace’s waterproof membrane for any damage, moisture, or signs of poor adhesion. The surface must be dry, stable, and free from dust, oil, loose material, or standing water. Minor imperfections should be patched and smoothed out—any cracks, blisters, or compromised areas may lead to adhesion failure. Allow all repairs to cure fully prior to proceeding, and avoid application during or immediately after rain.

Step 3: Mix and Apply the Resin System

Once the primer has cured, you are ready to mix your chosen resin system. Carefully follow the product’s mixing ratios and instructions to achieve a uniform blend. For white or light stone finishes, use “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit to ensure non-yellowing clarity; for coloured aggregate, use “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits, or opt for the all-in-one “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin for streamlined installation.

Combine resin and stones thoroughly in a clean mixing bucket, then evenly distribute the mixture across the terrace using a trowel or spatula. Work promptly to prevent premature setting. Compact the mix gently to achieve a consistent depth and texture, and edge carefully for a refined finish. Pay particular attention to upstands, joints, and drains to prevent future water ingress.

Tips, Common Mistakes, and Troubleshooting

Always check weather conditions before beginning—humidity and temperature extremes can impair resin setting and bonding. Incomplete surface preparation or missed primer spots typically cause delamination or poor durability. When mixing, avoid under-blending, which may result in patchy or weak areas. If any surface defects appear after curing, lightly sand and refill with the appropriate resin/aggregate mix. Patience during each curing stage greatly improves long-term performance and appearance.
