Are you looking for a reliable way to tightly seal joints on a terrace, balcony or concrete structure so they can withstand intensive use and substrate movement for years? CLEVERSEAL PU35 polyurethane sealant forms an exceptionally flexible, permanently waterproof compound that moves with the substrate, effectively protecting joints against water penetration and the damaging effects of chemicals.
✅ Non-sagging (thixotropic) – the thick paste adheres perfectly to both horizontal and vertical surfaces
✅ Permanent waterproofing – once cured, it forms a completely watertight barrier that protects terraces, balconies and other structures
✅ Excellent adhesion – bonds effectively to most construction substrates without the need for a primer
✅ Easy application with a cartridge gun – precise dispensing allows the joint to be filled accurately and cleanly
Filling and sealing expansion joints and gaps on terraces and balconies
Polyurethane
Actual material consumption depends directly on the width and depth of the expansion joint and the shape of the prepared gap. To make it easier to plan the required quantity, the approximate coverage per package is provided below:
| JOINT WIDTH | JOINT DEPTH | COVERAGE (1 PACK 600 ML) |
| 10 mm | 5 mm | ~6 m |
| 20 mm | 10 mm | ~3 m |
| 30 mm | 15 mm | ~1.3 m |
Important: The values provided represent theoretical consumption – when planning the work, it is advisable to allow for a small reserve to account for possible substrate irregularities.

A terrace and balcony are spaces for relaxation – but also some of the most demanding areas. Rain, snow, frost, intense sunlight, standing water… Without proper waterproofing, even a perfectly constructed terrace can start causing serious problems after just a few seasons.
