With high water and salt resistance, it is suitable for applications in very damp environments, such as masonry affected by rising damp and accompanying salinity problems. It can be used as a bedding plaster, being suitable for the rebuilding of damaged, weakened or partially collapsed walls with missing stones or bricks. It can also be used for plastering and rendering works.

Structural Reinforcement of an Old Barn with Betoncino MGN

Here is an application example of the Betoncino Consolidante MGN structural reinforcement mortar used on an old barn with damaged, weakened masonry. 

Structural Crack Repair and Consolidation with Lime

Some Roman lime mortars are great structural consolidation materials as they are breathable, flexible, of adequate mechanical strength, yet softer than the bricks or stones it consolidates – conforming to all aspects of building consolidation. This 1930s residential building had some structural cracks that have been repaired with the Betoncino Consolidante MGN Roman structural consolidation mortar.

Application

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

betoncino-main-core-conservation

Base, Building, Consolidation, Flooring

  • 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.
  • No salt-inhibitors nor PVA bonding agents should be used before the application of the plaster. The plaster bonds well on its own.
  • 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 plaster in 10 mm coats.
  • Light key: give the plaster a light key using a wet brush. Do not cut into the material with the edge of a trowel.
  • Additional coats can be applied in further 10 mm increments. Use an embedded fibreglass mesh for extra reinforcement over the recommended thickness.
  • 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).
