Use FulasealPRO 840NS for: Coolroom construction, refrigeration unit assembly, insulation panel lap joints, and other permanently plastic sealing applications.

FulasealPRO 840NS: A Technical Overview

FulasealPRO 840NS is a butyl-based, non-skinning, non-sagging gunnable sealant designed for critical coolroom and insulation panel applications. Its permanently plastic formulation provides long-term moisture resistance and superior adhesion to a wide range of construction substrates. The product remains workable for extended periods, allowing for adjustments during installation without skinning over, making it ideal for professional panel joinery where a consistent, high-performance seal is required.

Applications in Practice: Trade Scenarios

For Coolroom Installers (On-site Applicators): Reliable Joint Sealing

The Professional's Challenge

Coolroom joints must be sealed quickly and stay flexible under sub-zero conditions. A skinning sealant can trap gaps or fail to seat properly during panel adjustments.

The Adheseal Solution

FulasealPRO 840NS stays open and non-skinning, letting you reposition panels without tearing the bead. Its butyl formulation ensures a permanent, water-tight seal that flexes with temperature changes.

Best Practice Note

Apply a continuous 5 mm bead along lap joints, maintaining consistent gun speed for even coverage. Wipe any excess with a solvent-dampened cloth before final cure.
