description abstract	This guide includes the selection factors for and use of protective sealers for highway purposes to be applied to hardened concrete for the purpose of protecting new concrete or prolonging the life of sound, in-service concrete. Information in this guide is not applicable to the repair of badly deteriorated concrete. Sealers may be divided into two basic types: coatings, which remain on the surface; and penetrants, which penetrate into the concrete to some measurable depth. There are strong differences of opinion about the effectiveness and durability of some types of sealers under actual service and conditions as opposed to laboratory tests which may show the sealers to be effective. It must also be understood that there can be considerable differences in performance of material from different manufacturers for the same type of sealer. The values stated in SI units are to be regarded as the standard.
