SLV is a lower viscosity version of Flexible. At 200 cps, this formula pumps easier, especially in cold temperatures, and reacts much the same as Flexible. The system runs on a pint of Accelerator B per 5 gallons of resin and produces a reaction profile similar to our other injection resins. SLV may be used in the same manner as Flexible and for the same type of repairs. History has shown us that contractors addressing tight cracks prefer the SLV due to the lower viscosity. In other cases where the grout needs to flow for longer distances while reacting, SLV performs well due to its low viscosity.
