The method for sand blasting with wet sand comprises the mixing of sand with water in a pressure container (1) and the projection of the mixture by means of an additional agent from a nozzle (3). As a projection agent, compressed air or water underpressure is used for underwater working conditions. An apparatus for implementing such method comprises a pressure tank (1), a pressure water conduit, a nozzle connected by a flexible pipe to the pressure tank, the nozzle (3) being also connected to an additional projection agent source and having an inlet for the sand-water mixture.
