Two stage Rema Stem Repairing.
If using a Rema Stem repair system, follow the same milling procedure starting from the inside, then reverse the cut by milling also from the outside of the tyre. At this stage all debris should be removed from the tyre by vacuum, before applying REMA TIP TOP Blue Cement into the puncture channel.
Allow no drying time, place the Rema Stem unit into the wire pulling tool, and cement the whole stem unit with the blue cement. Thread it through the injury remove the wire pulling tool and pull the stem into position with pliers, leaving 4 to 5 mm of stem inside the tyre. After wiping away remains of cement with a clean cloth, buff the stem until it meets the liner level.
Place an appropriate patch unit centre over the injury, and mark the area to be buffed.
Buff the area either with an encapsulated wire brush or a dome rasp if repairing a truck tyre. Use a brass brush and vacuum to clean the buffed area and remove all buffing debris from the tyre.
Apply REMA TIP TOP Cement Blue to the buffed liner area, allow time for drying before applying the UP patch repair unit. Stitch from the centre working outwards, then finally stitch the patch border area. Apply REMA TIP TOP Inner Liner Sealer to the border area and over buffed area inside the tyre. Cut the outer stem flush with the surface of the tread without stretching it.
Both Minicombi and Rema Stem system are classed as permanent vulcanised repairs. As said before, plugs inserted from outside the tyre are not repairs but temporary seals.
Any temporary plug forced into the tyre from the outside cannot repair the original damage or produce a realistic internal tyre inspection. Many temporary seals never do get converted to permanent minor repairs, as the operator either thinks the tyre is repaired or puts off the tyre repair until tomorrow, but tomorrow never comes.

The tyre should be returned to the rim and inflated to its normal working pressure before cutting
the stem during this procedure.
