      How to Use

      Surface Preparation

      The surface shall be cleaned thoroughly of all contaminants
      like dust, traces of curing compound, oil and grease. All
      surface imperfections, nail head protrusions, structurally
      unsound and friable concrete shall be removed and
      repaired with a suit-able Polycrete* concrete repair mortar.
      The surface must be dry before priming with Polyprime SB.

      Application

      Mix the contents of the pail or drum for a few minutes to
      remove any sediments. apply the primer @4-6 m²/L to a
      clean smooth and dry surface by brush/roller. Allow the
      primer to dry prior to the application of the membrane.
      For highly porous surfaces application of a second coat is
      recommended.
