Product Overview

Adheseal PU25 FC is a single-component moisture curing polyurethane construction sealant. It is a tough, durable, and mould-resistant sealant with excellent chemical resistance. This fast-curing polyurethane provides a highly flexible bond and exhibits excellent adhesion to most common building materials. It is suitable for various applications, including perimeter sealing, curtain walls, masonry joints, expansion joints, tile joints, metal cladding, pavements, car parks, driveways, ducting systems, and general construction. It can also be used as an adhesive for lightweight components.

Advantages

  • Highly flexible
  • Fast curing
  • Paintable
  • Tear-resistant
  • Excellent adhesion to most common building materials
  • Anti-fungal
  • Tested to AS1530.3 standards

Joint Preparation

Care must be taken to ensure that the substrates are sound, clean, and free from contamination. If necessary, clean with Adheseal cleaning solvent. Priming is not normally required, but adhesion testing is recommended for suspect surfaces. Use the correct primer when required and allow it to dry. It is highly recommended to prime floor joints. Refer to the Primer Selection Chart.

Backer Rod

Use Adhefoam open cell backer rod where required. Closed cell backer rod is also suitable, but care must be taken not to damage the outer skin of the rod, as this can cause gassing (bubbles) in the sealant. When the depth of the joint does not allow for backer rod, a bond breaker tape is required to prevent three-sided adhesion.

Application

Fill the prepared joint completely, taking care not to entrap air, as entrapped air may cause bubbles in the sealant. Dry tool immediately before the sealant skins. The tooling time is a minimum of 10 minutes, depending on temperature and humidity.

Great Product!

Have used similar polyurethane bases sealants before with varying results. PU25 is consistently high standard and provides excellent adhesion and flexibility. Dries pretty quick and the low VOC makes it perfect for confined spaces.
