MAPEI Primer L
Advanced-Technology, Acrylic Latex Primer for Concrete.
Primer L is a concentrated, solvent-free acrylic primer used before the installation of underlayment materials. It is green for easy identification.
Primer L improves the bond between a properly prepared and profiled concrete substrate, and selfleveling underlayment.
Primer L can also be used as a primer for gypsum-based underlayments and patches.
