Mult‐E‐Prime 505 is designed to provide an effective seal and bonding coat on unfinished concrete floors. Through careful formulation and the use of an epoxy resin system, Mult‐E‐Prime 505’s extreme application flexibility allows its use as a seal coat before recommended finishes, as a one‐coat sealer system to prevent dusting or a two‐coat finish system that offers increased durability and sheen. Mult‐E‐Poxy 505 was also designed to aid in the control of concrete out‐gassing when used before additional coats.
