  • Larger crack shall be repaired by cutting crack area for V-shape before patching, mixing C-BONDING or DURABONDER (increase bonding & elasticity): SC-334 : water approximate ratio by weight 1:1: 0.25: and blending by drilled mixer for patching crack. PU sealant can also be used for crack patching Wait till patching area is completely dry prior to subsequent skim coats for 2-3 coats as per afore-mentioned instructions.
      5. Thin Coat on Light Weight Block Wall
  • Follow above instructions (1) for mixing .Patching between laying blocks to cover up the joints so that thin coat can be applied by steel/plastic trowel.
  • Using plastic trowel to apply first coat on the light weight block wall
  • Wait till first coat is dry and repeat for next coat(s).   Final coat shall be applied by steel trowel till the surface is smooth finish. and no visible mark/trace of uneven surface
