Primer pens provide a base coat for stronger adhesion. Additional primer pens are available for purchase in sets of five. Only for use with Unrip repair patches.
 
Instructions for Use:
Make sure to wash the latex clothing. Remove any dirt, shine, lubricants, or anything else that might stop a patch from properly sticking.
To activate the primer, remove the primer pen from the cardboard tube. Squeeze firmly to break the glass ampule to release the primer.
Once the glass amplule is broken, the white sponge at the end of the primer tube will be soaked in primer solution. Apply the primer to the desired repair location. Make sure to cover any area you expect an Unrip patch to stick to.
Wait 5 to 10  minutes for the primer to dry.
Apply the Unrip repair patch to the area where primer was applied.
