Compatibility

Icopal PUR Contact Spray Adhesive is compatible with tissue faced PIR insulations boards along with a variety of substrates commonly encountered in flat roofing applications such as timber, concrete, metal and more.

Important Note: The adhesive is not compatible with expanded polystyrene (EPS) or extruded polystyrene (XPS) insulation boards, due to the solvent content.

Icopal PUR Contact Spray Adhesive is suitable for bonding both on the flat and for vertical applications due to its instant grab, making it the ideal choice for detail work.

Application Benefits

Icopal PUR Contact Spray Adhesive is applied using a spray wand - allowing for easy, precise and rapid installation. The spray wand ensures a consistent spray pattern when applied to the substrate, therefor reducing wastage and ensuring an accurate and secure installation. The wand also removes the need for contractors to repeatedly bend over throughout the installation, combined with a long, PTFE braided hose the Icopal PUR Contact Spray Adhesive system provides maximum manoeuvrability.

The high tack properties of Icopal PUR Contact Spray Adhesive give it instant grab making it ideal for upstands and detail work where vertical grab is essential.

Surface Preparation

Ensure the substrate is structurally sound and free of surface laitance, oils, grease, dirt, frost, moss, lichen, and loose material.

The surface should be smooth and level, free from sharp projections and any material which would hinder adhesion. The surface should be free of ponded water. Do not apply if rain is imminent, remove all ponded water and allow at least 1 hour drying before applying the adhesive.

Canister Set-up Procedure

  • Attach one end of the hose to the spray wand and tighten the nut with a spanner.
  • Remove the black cap on the canister valve and attach the hose to the valve and tighten the nut with a spanner.
  • Once both nuts are tightened and secure, open the valve on the top of the canister.
  • DO NOT close canister valve until the canister is completely empty. To do so may cause adhesive to block in the hose.
  • When work is complete, turn the black valve on the spray wand clockwise until fully closed. Clean the end of the spray wand with Hose and Gun Cleaner ensuring that the aperture is clean. Once the canister is empty, the hose to the canister valve can be removed and attached to a fresh canister.

Application

  • Begin spraying adhesive by pulling the trigger on the spray wand, adjust the spray width by turning the black valve on the spray wand.
  • Position the waterproofing membrane, and fold back.
  • The adhesive is applied by spray application using a the appropriate spray gun for field area or detail work. During application keep the tip of the gun approximately 100 − 250mm above the substrate. Maintain a constant speed of application during spraying.
  • Spray an even coat of adhesive onto the substrate and to the back of the membrane allowing the adhesive to cobweb across the surface with minimal overlap for thick membranes or approximately 50 – 70% overlap to successive passes for thin membranes to reduce risk of telegraphing.
  • Important: Spray apply the adhesive to the back of the membrane at right angles to the adhesive on the substrate thereby achieving a cross bond for maximum adhesion.
  • Hold the spray gun at 90° angle to the surface and apply a uniform generous coat of adhesive, ensuring 80-100% coverage of two even coats of adhesive to both substrates. Ensure each two-metre pass takes a minimum of 10 seconds. Do not allow the adhesive to puddle.
  • Give the solvents 1-2 minutes to evaporate at 20°C. Bring the surfaces together, working from the centre outwards. Avoid wrinkles in the sheet. Immediately roll with a weighted roller or broom to achieve maximum contact and a smooth, flat finish without air pockets.
