                  Concrete surface shall be free of loose particles, ridges, projections, voids and droppings
                  that would interface with the application of the coating. All laitance shall be removed from
                  the surface.

          1.03.
          1.04.
                  Concrete shall be cured for 28 days prior for the application of the coating
                  At no time should Cemtec A1 Black PU be applied over concrete surface having moisture
                  content greater than 20%.
                  Concrete surface to receive coating shall be free from oil, grease, dirt, debris and other
                  contaminants that may adversely affect adhesion.
          1.05.   Repair holes and cracks with concrete repair products recommended by CMCI.
          2.      Placing
          Base Coat: CEMTEC A1 BLACK PU
          2.01.   Prepare primer coat by mixing one part xylene to three parts Cemtec A1 Black PU. For
                  horizontal or vertical surfaces, apply a thin coat of primer at a thickness of 175 microns wet
                  film thickness. Application of Cemtec A1 Black PU shall be by any of the following: Airless
                  spray; Roller; Squeegee.
          2.02.   Allow overnight curing then apply the 1st coat of Cemtec A1 Black PU targeting a thickness
                  of 375 microns wet film.
          2.03.   Allow overnight curing then apply the 2nd coat of Cemtec A1 Black PU targeting a thickness
                  of 375 microns wet film
          2.04.   Care should be taken that no excess liquid collect on the edges of the wall converging on
                  the floor, if this occur the liquid must be evenly spread out by brush. The total dry film
                  thickness of Cemtec A1 Black PU (primer + two coats) should be approximately 700
                  microns.
          2.05.   Allow overnight curing of the base coat prior to application of the Cemtec AL PU Coating.
          Top Coat: CEMTEC AL PU COATING
          2.06.   Ensure that the base coat of Cemtec A1 Black Pu has a cured overnight prior application of
                  Cemtec Al PU Coating.

                  Apply the 1 coat of Cemtec AL Pu Coating targeting a thickness of 250 microns wet film.
                  Application of Cemtec AL PU Coating shall be by any of the following: Airless Spray; Roller;
                  Brush; Squeegee.

                  Allow overnight curing then apply the 2nd coat of Cemtec AL PU Coating targeting a
                  thickness of 250 microns wet film.
                  Care should be taken that no excess liquid collect on the edges of the wall converging on
                  the floor, if this occurs the liquid collect must be evenly spread out by brush. The total dry
                  film thickness of Cemtec AL PU Coating (two coat) should be approximately 300 microns.
          2.10.   Full curing is achieved after 48 hours.
