ABSTRACT:
A method is disclosed for removing water soluble salts from a concrete substrate in a wet blast system in which a bicarbonate abrasive is blasted in a high purity pressurized water stream against the surface of the concrete substrate to prepare the surface for the application of a coating. The method includes the steps as indicated in FIG. 8 in which a high pressure wet blast of high purity pressurized water and sodium bicarbonate abrasive is first applied by a nozzle (14) against the surface of the concrete substrate with the water soluble salts being removed or neutralized. Next, a high purity pressurized water without abrasive is applied by the nozzle (14) against the surface of the concrete substrate for washing the surface clean and removing the neutralized water soluble salts. The water for the wet blast system is of a very high purity characterized by a conductivity of between 0.5 and ten (10) micromohs/cm.
