Five surface applied concrete sealer treatments were evaluated in the laboratory for water vapor transmission, saltwater absorption, alkali resistance, depth of penetration, UV exposure and cyclic saltwater ponding, chloride content, and freeze-thaw resistance. The five treatments included silane, high molecular weight methacrylate (HMWM), epoxy, silane basecoat/HMWM top coat, and silane basecoat/epoxy top coat. The same treatments were applied in four locations in Southwestern Idaho to initiate a long-term (4 year) field evaluation of the treatments. In the laboratory tests, the dual treatments of a silane basecoat followed by an epoxy or HMWM exhibited the best performance. Of the single compound applications, the epoxy, silane, and HMWM exhibited the best performance in descending order for saltwater absorption, alkali resistance and freeze-thaw resistance. Only the silane had a measurable depth of penetration and had the best water vapor transmission ability.
