Adheseal PU-15 is a durable and highly flexible single-component moisture curing polyurethane construction sealant. It offers excellent adhesion to most common building materials and exhibits good chemical resistance. This low modulus elastomeric sealant is designed to provide reliable sealing for a wide range of applications.
Adheseal PU-15 is suitable for the following applications:
Prior to application, ensure that the substrates are sound, clean, and free from contamination. If necessary, clean with Adheseal cleaning solvent.
Priming is generally not required for most substrates. However, for suspect surfaces, it is recommended to perform adhesion testing. When priming is necessary, apply the correct primer and allow it to dry. It is highly recommended to prime floor joints. Refer to the Primer Selection Chart for guidance.
Where required, use Adhefoam open-cell backer rod. Closed-cell backer rod is also suitable, but be cautious not to damage the outer skin of the rod, as it can cause gassing (bubbles) in the sealant. In cases where the depth of the joint does not allow for backer rod, a bond breaker tape is required to prevent three-sided adhesion.
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.
Adheseal PU-15 is not suitable for long-term water immersion or internal swimming pool applications.
The available colours for Adheseal PU-15 are Concrete Grey, Black, and White. Other colours are available in batch quantities with extended lead times.
Adheseal PU-15 is paintable with most commonly available paints. However, it is crucial to ensure that the sealant is fully cured before applying paint. Failure to do so can result in retarding the curing of the PU sealant and the paint topcoat, resulting in a tacky surface.
