Composition and Materials:

OlyBond500 is a dual component, reaction cure polyurethane adhesive. The blowing agent is water (no HCFC). OlyBond adhesive is available in 5 gallon sets of diisocyanate (Part 1) and resin (Part 2) or in a dual tube set (Part 1 and Part 2).


Do NOT use OlyBond500 Adhesive:

  • with isocyanurate board stock larger than 4' x 4'.
  • when ambient or substrate temperatures are below 45°F or above 120°F.
  • during inclement weather.
  • on wet surfaces.
  • on any roof deck that shows signs of deterioration or loss of structural integrity.
  • on dirty or grease-laden surfaces.
  • after the expiration date. Contact Olympic at 800-633-3800 for options and instructions.


OlyBond500 adhesive is packaged in 5 gallon sets consisting of Part 1 (diisocyanate) and Part 2 (resin) or in dual tube sets (Part 1 and Part 2). OlyBond500 is approved by most Roof System Manufacturers and is approved by FM.


Containers should be stored between 45°F and 95°F. At these temperatures, the shelf life is 12 months from the date of manufacture. Check each product temperature with a clean thermometer. The minimum product temperature before putting into the OlyBond500 dispenser must be 72°F. The minimum ambient and surface temperatures must be 45°F or above.


Lightweight Concrete, Structural Concrete, and Plywood:

These surfaces must be free of any debris, dirt, oil, grease, and standing water before applying OlyBond500 adhesive.

Built Up (BUR) and Modified:

Surfaces must be free of any debris, dirt, oil, grease and standing water. Contact the Roofing Membrane Manufacturer for details.


The upper flange of the steel deck (bonding surface) must be free of debris, dirt, grease, oil, and standing water. On new steel, the shop coating must be removed. The bonding surface must be free of any cleaner before applying OlyBond500 adhesive.


Review the roofing insulation plan. Isocyanurate insulation boards to be attached must be no larger than 4' x 4'. When installing multiple layers of boards, apply the boards using staggered joints.

Existing Polyurethane Foam:

Remove the surface of the polyurethane roof, including the coating, with a scarifier (minimum 1/2"). The bonding surface should be blown clean before applying OlyBond500 adhesive.


OlyBond500 adhesive has excellent adhesion to clean metal. Prime all non-ferrous metals (aluminum, copper, stainless, etc.) to further increase adhesion. Acceptable primers include epoxy, chlorinated rubber, and wash primer.


  • PaceCart, pour Part 1 and Part 2 components into their respective hoppers on the dispenser.
  • For PaceCart 2, install Part 1 and Part 2 components following instructions on Bag-in-Box package.
  • Open flow valves on the dispenser completely and turn machine on. This allows material to be pumped at a 1:1 ratio through the static mixing tip and onto the substrate in a semi liquid state. Apply fluid mixture in rows spaced 12" on center that spread to several inches wide before rising 3/4"-1". The insulation board is then laid into place and walked in to assure complete adhesion. Curing takes place in 4 to 8 minutes.

Spot Shot:

Remove stopper from cartridge and attach mixing tip. Insert cartridge into the appropriate 1:1 ratio caulking gun. Using a steady trigger motion, apply OlyBond500 adhesive to the substrate.


Apply the fluid mixture in rows spaced 12" on center that spread to several inches wide before rising 3/4" to 1" long. Lay the insulation board into position and walk into place to assure complete adhesion. Continue walking on boards until adhesive sets (4-8 minutes). Typical coverage rates are between .75 and 1.25 gallons per 100 square feet, resulting in the board achieving 60 to 75% adhesion. The application rate must be increased for rougher surfaces and will vary depending on roughness.

Reaction Time:

OlyBond500 adhesive is designed to react at a slower rate than spray polyurethane foam. It is important to vary the speed of the reaction in relation to the temperature (substrate and ambient) at time of application to ensure a complete reaction process. Review the chart below for correct Part 2 component selection.
