All metal must be below the edge of the roof deck. Page 1of 17 VG 11.16.07 P.O.

The Dicor fleece tape or mesh tape is preferred. Page 3 of 17 P.O.

Prior to applying the bonding adhesive in order to verify proper length and width of the roof kit. 10 The EPDM sheet is pulled back or booked to expose the front half of the roof deck.

Box 1806 - Elkhart, IN 46515 - Phone (574) 264-2699 - Fax (574) 293-2017 11 The front half of the roof is ready for the Dicor adhesive to be applied. 12 The adhesive is evenly spread over the complete roof surface. At a rate of 160 square feet per gallon. Page 6 of 17 P.O.

This will provide tight EPDM over the roof seams and a smooth surface. Caution should be used to prevent pushing the adhesive around under the rubber. 18 All wrinkles are moved to the rear.

As the adhesive dries the print will disappear. Page 16 of 17
