TREMproof Microrea S3 AP is a 100% solids, spray-applied pure polyurea waterproofing membrane. It offers rapid curing, allowing for faster installation. It is ideal for podiums, rooftops, balconies, and other structures requiring durable waterproofing.

Yes, TREMproof Microrea S3 AP can be used in planter boxes, but an anti-root additive must be added to Part B before application. This additive prevents root penetration, ensuring long-term waterproofing performance. The recommended dosage is 1.1% by weight into the Part B (polyol component).

The primer depends on the substrate. Use Vulkem 171 for low-moisture porous substrates, TREMprime EP for poor-finish porous substrates, TREMproof 200EC for high-moisture concrete, and TREMprime Non-Porous for metals, PVC, or glass. Always ensure substrates are clean, dry, and properly prepared before priming.
-
Store in original, sealed packaging in a clean, dry place between 18°C and 25°C. Keep Part A and Part B separate, avoiding exposure to direct sunlight. Prevent water contamination in Part A, as moisture can cause pressure buildup inside the drum, potentially leading to safety risks.
-
No, it is not UV stable. Prolonged sun exposure will cause yellowing and degradation. If used in exposed areas, a UV-stable top coat, such as Vulkem 346 or Vulkem 951NF, must be applied within the recommended overcoat window to protect the membrane and maintain durability.
