Jahn M60 – Plaster Mortar

Specially engineered plaster and stucco mortar for use on new or existing brick or stone substrates

M60 Plaster Repair Mortar
Description:

Jahn M60 Plaster and Stucco Mortar is a cementitious, single-component mortar that eliminates the need for the usual three-part application process (clean, scratch, finish).  M60 can be applied as a ground coat or a finishing coat and is available in interior and exterior formulations.  It is also available in plaster and stucco variants.

Contains no acrylic or latex bonding agents and exhibits a superior chemical bond to prepared substrates.  M60 is proven in situations where repeated water and salt saturation have occurred.

Benefits:
  • Ready to use: Mixes with water only – no on-site “chemistry” resulting in product variation.
  • Can be applied on all mineral, stony, absorbing and load-bearing substrates.
  • Purely mineral: Protects the substrate by allowing salts, water vapour, and liquid water to reach the surface, preventing failure due to salt expansion or freeze/thaw cycles.
  • Tenacious Adhesion without relying on synthetic bonding agents.
  • Choose from standard or factory custom colouring. Closely matches existing masonry.
  • Water Based: Environmentally and user safe. No solvent clean-up or disposal problems.
