Betoncino Consolidante MGN - Description

BETONCINO CONSOLIDANTE MGN is a premixed structural reinforcement and consolidation lime mortar, suitable for the consolidation of all types of deteriorated or damaged walls – brick, stone or of mixed construction – which require heritage-friendly physical reinforcement.

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.

Composed of only natural lime based materials, Betoncino Consolidante MGN is compatible with all traditional binders and mortars used in the construction of historic walls.

It an be combined with various mesh systems – such as FRP (Fibre Reinforced Polymer) or FRCM (Fibre Reinforced Cementitious Matrix) consolidation systems – including fiberglass, carbon, polymer, steel or other meshes. depending on the characteristics of the masonry and the problems that need to be solved.

Protecting Joists and Timber Elements

Joists and timber beams are often structural elements or have some sort of structural function. Being in contact with the masonry (e.g. joist ends), they can be subject to excessive moisture from damp walls.

The Betoncino MGN Roman structural mortar works well with timber, protecting timber elements from liquid moisture while allowing them to breathe and stay dry, free from rot.

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:

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).
