Resin is not suitable for all surfaces. You should avoid applying resin on: Damp or wet substrates: Moisture will prevent adhesion and can cause bubbling or delamination. Unstable bases: Cracked, loose, or crumbly surfaces can cause the resin to fail. Old loose gravel: Without a suitable binder, this surface will not provide necessary stability for resin installation.

Can I Apply Resin Over Any Terrace Surface?

Considering a resin surface on your terrace? Successful results depend heavily on the surface beneath. Not every terrace base is suitable for resin application, so understanding key substrate requirements helps you achieve a beautiful and long-lasting finish.

Which Surface Types Are Suitable?

For the best results, resin should be applied over a substrate that is strong, level, dry, and free of contaminants. Concrete is ideal, offering an absorbent and stable base for resin adhesion. Some resin systems can also be used over tiles and cement-based screeds, provided they are solid and thoroughly cleaned.

Concrete: The most reliable and straightforward substrate for resin application on terraces.
Tiles: Can work if securely fixed and prepared to remove any glossy coating.
Existing decorative stone: Typically requires stabilisation or special binders for proper adhesion.
