Grind bondlines to bare metal. Clean and pre-treat the bonding surface with TEROSON® VR 10 using a lint-free cloth. Apply masking tape on the side rail and new roof.
Place the new roof in the cleaned body frame to make sure that it fits.
If you work on bare metal, apply TEROSON® BOND All-in-one Primer for surface preparation for the windscreen adhesive dam / mounting aid.
Open TEROSON® EP 5065 cartridge and squeeze out small amount of material until both adhesive components run equally. Clean tip. Apply the mixing nozzle and discard the first 5 cm of the mixed adhesive.
Apply adhesive to the new roof and the body frame. Spread adhesive with a spreader or brush. All bare metal areas should be covered with adhesive (roof and car body frame) for corrosion protection.
Apply TEROSON® MS 222 to roof bows for anti flutter. Mount new roof within processing time of approx. 30 min. Alternatively, apply TEROSON® PU 9161 AF after roof mounting. Neither product causes read-throughs.
Apply a bead of TEROSON® BOND 60 on the primed surface as a mounting aid parallel to the flange (at a distance of approx. 5 to 8 mm). Consider the processing time.
Apply a bead of TEROSON® EP 5065 for bonding. Either to the new roof or to the body frame.
Fit the new roof. If spotwelding is required, this work has to be done within 60 min. after product application.
Form adhesive and remove excess product with TEROSON® VR 10. Then remove masking tape.
Cure product at 23°C room temperature for 48 hours. Curing can be accelerated by heat with infrared (30 min. at 80°C object temperature) or heating pads.
