Designed for commercial and industrial steel framed structures, where impact and abrasion are likely. Used in fully exposed and external applications, e.g. manufacturing areas and semi-conductor plants.


A Portland cement-based, factory-mixed material able to withstand freeze-thaw, wind, rain and other climatic conditions. It is lightweight, economical and fast to apply. The use of an injection process at the gun head sets this material typically within 15 minutes. The sprayed material bonds tightly to the substrate forming a durable surface that does not dust or flake. The product may be sprayed or troweled to various textures.

Features and benefits:

  • Ready to use.
  • The factory-mixed blend of common Portland cement and other inert materials requires only the addition of water for mixing and application.
  • May be sprayed or hand troweled after spraying to achieve a lightly textured appearance.
  • Can be mixed in standard plaster mixer. After mixing, MONOKOTE® Z-146 may be spray-applied with commonly available pumping and spraying equipment.
  • Portland cement base affords excellent fire protection characteristics in areas subjected to high humidity.
  • Hardness and durability help resist accidental physical damage.
  • Able to withstand freeze/thaw, wind, rain and other climatic conditions.
