EFFLORESCENCE

Efflorescence is a salt-like deposit, usually caused by moisture in masonry (both painted and unpainted). It looks like frost and if present, must be removed before any paint is applied. Wire brushing and washing usually removes it. If any efflorescent salts remain, wash surface with solution of 1 pint Muriatic Acid in a gallon of water. (Be sure to wear protective glasses and clothing). Rinse off solution and let dry completely. Prior to the application of any coating system, determine the cause of water migration in the masonry and take steps to eliminate it. This will prevent further efflorescence from occurring at damaging the new paint film.
