Water proofing of roof terraces, Basements, Retaining Walls, Water tanks etc with Zydex Zycoprime / Elastobar / Equivalent solution so as to form a water-resistant cementitious bonding coat and to form on-site seamless cross-linked elastomeric membrane on the concrete surface to reduce its porosity. Creating a cementitious elastomeric polymeric membrane of Elastobar and Zycoprime/Equivalent after application of Zycosil & Zycoprime Solution in New Construction. Take equal parts of Elastobar and Cement and form a paste. Add little water to the paste to make it brushable. Apply the paste on surface with brush. Leave the surace for drying for at least 4 – 6 hours to get elastomeric membrane. After this application, make one more layer of rough cementatios membrane using mixture of 1 Part of Zycoprime + 1 Part of Cement + 1 Part of fine sand. Apply paste on the surface with a brush to make a rough texture. Now your surface is ready to bond well with tiles/screed.
