    • Clean the surface thoroughly with mechanically means and make the surface free from dirt and loose material
    • In existing old terraces with brickbat coba or screeds , the substrate must be checked for its soundness.
    • Damaged or hollow portions, sharp edges must be cut and removed till the mother slab.
    • The slab should be recoated with slurry of Apcobuild Seal n safe and cement (1 :1) proportion. After drying the brickbat coba in that proportion should be reinstated by mixing Apcobuild Seal N Safe in base slurry.
    • In other areas where the coba is sound, the surface cracks must be filled with Apcobuild Crackfiller paste or polymer modified mortar.
    • Dilute Apcobuild Flex PU WB with water in 1:1 mixing ratio as a primer coat, then pour Apcobuild Flex PU WB into these cracks and wait for it to dry.
    • Bitumen based waterproofing treatments if existing, must be completely removed by mechanical scarification or by any other effective mechanical means.
