PROBLEM TO BE SOLVED: To provide a bonding method which permits a sufficiently long time elapsed after adhesive application and therefore excellent workability and permits bonding excellent in water resistance performance by a short-time compaction of 3-10 min at ordinary temperature throughout a year with a water-based adhesive. SOLUTION: The bonding method comprises bonding adherends at least either of which is a porous material with an acetoacetyl group-containing synthetic resin emulsion controlled to a temperature of 15 to 80°C. In a desirable embodiment, the bonding method is one wherein the acetoacetyl group-containing synthetic resin emulsion contains acetoacetylated polyvinyl alcohol. In another desirable embodiment, any of the bonding methods is one wherein the acetoacetyl group-containing synthetic resin emulsion contains a resin obtained by copolymerizing an acetoacetyl group-containing monomer with another monomer.
