Apply the bonding adhesive to the exposed roof deck and NOT to the EPDM membrane as the adhesive is to be applied as a one surface WET LAMINATE using a notched trowel to spread the adhesive in a pattern over the decking. Wait a few minutes for the adhesive to tack off then slowly fold the EPDM roofing membrane back into place while the adhesive is still wet. To ensure adhesive transfer and a good bond, use a stiff bristled push broom and force the membrane into contact with the adhesive on the roof deck. Repeat the process on the other half of the EPDM membrane. Trowel application is the recommended application as per the instructions as a ONE surface WET LAMINATE. However, if you wish to use a paint roller, we recommend using a 9" fine nap paint approved roller. If you use the roller, and not a trowel, you need to put the adhesive on BOTH surfaces and let TACK dry for 5 minutes or so, like a 2 sided solvent contact adhesive, depending on weather and heat conditions. Using this application method may require the use of more adhesive than the single sided process.Then, put the 2 pieces together. Full cure normally occurs after 24-48 hours.
