GAF OMG OlyBond500 SpotShot Two-Component Polyurethane Insulation Adhesive, 1500 mL Two-Part Kit

GAF OMG OlyBond500 SpotShot is a two-component, low-rise polyurethane insulation adhesive for adhering board stock to many roof substrates in new and reroof work, including board-to-board attachment. Each kit dispenses 3/4 in. to 1 in. beads through the portable SpotShot applicator, and one kit secures boards as the chemical cure takes hold in about 4 to 8 minutes.

Key Features:

• Rapid chemical cure: Boards are secured approximately 4 to 8 minutes after application, depending on temperature and weather conditions.
• Low-rise polyurethane: Dispensed in 3/4 in. to 1 in. wide beads that spread to several inches while rising 3/4 in. to 1 in. above the substrate.
• Portable applicator: The lightweight, portable SpotShot system allows easy insulation board installation on the roof.
• Board-to-board: Can be used to adhere insulation board to insulation board as well as to the deck or substrate.
• Low VOC formula: Uses water instead of HCFC as the blowing agent, making it low VOC.
• System compatibility: Compatible with most single-ply and some asphaltic systems.
• Strengthens system: Adhesive attachment strengthens the overall roof system.

Expert Verdict Reviewed by the SuperArbor Pro Desk

OlyBond500 SpotShot is a strong choice for low-slope insulation attachment where mechanical fasteners would telegraph through thin boards or hot asphalt is impractical. Keep kits at moderate temperature before use since cure time slows in cool weather, and always walk boards into the wet beads promptly so the low-rise foam fully contacts the substrate. For thick multi-layer stacks, bond board to board with the same material rather than fastening through the stack.

Wear gloves and eye protection when handling two-component polyurethane adhesives, and follow the manufacturer’s application and substrate preparation instructions for the roof system.
