CanapaTerm MGN - Description

CANAPATERM MGN is a warm natural lime-hemp insulating plaster, used for thermal and acoustic insulation. Due to the mix of hemp and natural lime offers a number of benefits, such as:

  • Makes the building warmer, resulting in significant energy savings on heating bills
  • Regulates internal humidity, resulting in warmer buildings during the winter and cooler buildings during the summer
  • Eliminates the risk of respiratory diseases caused by mould and moisture
  • Reduces indoor air pollution
  • Absorbs internal CO2
  • Ensures overall better living comfort

Product Combinations

Although all MGN plasters can be used on their own, in many applications they perform best when certain materials are applied together as a plastering system complementing and reinforcing each other.

Here are some other plasters which are recommended to be used with this one.

Application

Here are some key technical points about how to apply this material correctly:

Thermal

  • Clean the masonry: the plaster must be applied on a cleaned and uniformly wet substrate. All crumbling and loose parts must be removed by brushing so the masonry is free of dust, salts and oils. If possible, also wash the walls with a pressure washer; this will clean and wet the walls in one go. Close larger holes with lime mortar and pieces of bricks.
  • Mixing: mix the material with clean tap water only without adding anything else (no other material or additive), until a homogenous, creamy-consistency mix is obtained. 
  • Application: apply the thermal plaster in (up to) 20 mm coats in one pass, without compressing the material. Wait for the previous coat to harden (2-3 days depending on ambient conditions) before applying the next coat. The last layer must be levelled to make the application of the finishing easier.
  • Drying time: as porous thermal plasters take up significantly more water than denser “regular” plasters, they have proportionally longer drying times. Thus, before applying the finish, it is advisable to let the thermal insulation dry for 15-20 days.
  • Finishing: for better mechanical protection thermal plasters should be finished with a dedicated finish (e.g. Megastuk MGN) – these are mechanically more resilient, longer lasting than ordinary lime putty finishes.
  • Application conditions: ambient and wall temperatures must be between +5 to +30°C during application. Surfaces should be protected from rain and humidity until they have completely dried (approx. 3 – 10 days depending on weather conditions).
