The present invention relates to aqueous liquid for primers which contain a copolymer mainly formed with a cationic monomer, an alkoxysilane monomer and an ethylenic unsaturated monomer in aqueous medium, wherein low viscosity and superior permeability to basic materials are materialized in spite of its high concentration. Therefore, this liquid for primers is effective for liquid for primers applied as inorganic porous basic reinforcing materials such as concrete, mortar and the like. |
