How can I prepare various surfaces prior to vinyl application?
It is always important to clean surfaces just prior to any installation. For painted metal and wood, use isopropyl alcohol. For glass, use isopropyl alcohol or a water/vinrgar mix, for acrylic or polycarbonate, use non-siliconized acrylic cleaner or anti-static rag to remove static charge and last minute dust, for banners and awnings, use isopropyl alcohol or a vinegar/water mix, and for expanded PVC sheet, use vinegar followed by a quick wipe with toluene.
