Note: Flat trowel application. Application rates will depend on the quality of application, substrate board flatness, texture and density. These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Application steps

MIXING

  • Place contents of each bag in a suitable container which is clean and free of foreign substances.
  • Do not use a container which has contained or been cleaned with a petroleum-based product.
  • Fill the container with advised amount of clean, potable water.
  • Add SikaWall®-1030 Alpha Dry Base Coat in small increments, mixing after each addition.
  • Mix the contents of the SikaWall®-1030 Alpha Dry Base Coat unit with a low-speed drill and paddle mixer until thoroughly blended.
  • Additional SikaWall®-1030 Alpha Dry Base Coat or small amount of water may be added to adjust workability.
  • Let it stand for 5 minutes, then remix and retemper before use.
  • Additives are not permitted.
  • Close container when not in use.

APPLICATION

Apply the base coat in 2 layers. First (1st) layer of SikaWall®-1030 Alpha Dry Base Coat shall be applied so as to achieve SikaWall® Reinforcing Mesh embedment with no SikaWall® Reinforcing Mesh colour visible. Allow for initial set (touch dry). Lightly abrade dried first layer with sandpaper, without damaging the mesh. Remove the dust and apply second (2nd) layer of SikaWall®-1030 Alpha Dry Base Coat. Allow to dry approx. 8 to 10 hours, depending on the ambient temperature, before the application of SikaWall®-15 Tinted Primer AE and SikaWall®-6000 range of finish coats.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water and soap immediately after use. Hardened / cured material can only be removed mechanically.
