GoBoard Pro Sealant

GoBoardĀ® Pro Sealant is a one-component, moisture-curing hybrid joint sealant designed for waterproofing and bonding GoBoard panels and related building materials. It is used to seal panel joints, seams, and fastener penetrations in both interior and exterior environments.

Formulated without solvents or isocyanates, the sealant supports low-odor application while maintaining reliable performance across a wide range of temperatures and jobsite conditions.

Key Features

  • Waterproof Joint Sealant: Seals panel joints, seams, and fastener penetrations to help maintain continuous waterproofing.
  • Multi-Material Adhesion: Bonds to GoBoard, metals, plastics, concrete, wood, foams, and ceramics.
  • Moisture-Curing Formula: Maintains permanent elasticity and supports up to 25% joint movement.
  • No-Sag Application: Suitable for both vertical and horizontal installations.
  • Fast Skin Time: Skins in approximately 15 minutes to support same-day tile installation.
  • Interior and Exterior Use: Designed to maintain performance in wet and exposed environments.
  • Standard Caulk Gun Application: Dispenses easily across a broad temperature range.
  • Low-Odor, Solvent-Free Composition: Contains no solvents or isocyanates.
  • Paintable and Non-Yellowing: Supports finishing after curing without discoloration.
  • VOC Compliant: Meets environmental and building requirements.
  • ASTM Certified: Meets ASTM C920, Type S, Grade NS, Class 25 or better.
