The Ceresit CO 84 concentrate added to the cement mortar allows obtaining aerated undercoat plasters. It is recommended for historic buildings, when renovating damp and salty walls in, inside and outside buildings in CO 84 strongly aerates and plasters the mortar,
increases plaster vapor permeability, prevents salt efflorescence. Plaster with the addition of CO 84 can be covered with thin-layer mineral plasters or paints with very low diffusion resistance, e.g. Ceresit CT 59 or Ceresit CT 54. For indoor and outdoor use.
