VersaFlex SL/45 is a self-leveling, 100% solids, flexible, two-component, rapid curing polyurea elastomer joint sealant material.  SL/45 is designed for 25% movement of installed joint width.  Recommended concrete cure a minimum of 28 days prior to installing joint filler or joint sealant.

SL/45 is used to fill random cracks, contraction joints, control joints or new construction joints on new or old horizontal concrete surfaces. SL/45 is ideal for use on elevated parking decks, balcony decks, pedestrian decks and bridge decks where its quick and positive cure will allow rapid return to service. SL/45 is highly flexible, retaining full properties and memory capability while allowing normal joint movement and accommodating slab movement where designed movement and thermal cycling will occur.
