TRITOprime™ is a low VOC asphaltic primer for spray or roll application to existing asphalt based roof systems, metal flashings, or concrete surfaces prior to installing the TRITOflex™ or TRITOtrowel™ products. The thin-bodied SP asphalt penetrates the surface and allows for a stronger cohesive bonding between the old surface and the TRITOflex™ products.
