VersaFlex VF 20 is a two-component isocyanate and resin blend primer for porous substrate applications. The low viscosity of VF 20 allows for maximum penetration of concrete. In hard trowelled concrete situations, VF 20 may be diluted to further reduce viscosity. VF 20 has a working time of 45 minutes. Apply VF 20 on concrete allowing product to penetrate the surface. Ponding on the surface is to be avoided.
VersaFlex VF 20 primer may be used with VersaFlex rapid curing polyurea sealants and spray coatings systems. It is designed for use in both interior and exterior priming situations. Allow VF 20 to properly cure prior to topcoating. VF 20 can also be used to reduce moisture vapor emission rates in concrete.
