Work Specifications & Application

Here are the recommended work specifications for this plaster.

Consolidation

█ [As needed] Injectable lime grout: after mixing with clean tap water, inject or pour the liquid grout into the wall fabric to fill in any voids or cracks to consolidate the inner structure of the wall.

Application Instructions

Here are some key technical points about how to apply this material correctly. Please have the applicators read / watch the application instructions below before applying the product.

APPLICATION VIDEO:

APPLICATION INSTRUCTIONS:

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.
IMPORTANT: Dry to wet mixing: plasters with hydraulic ingredients should always be mixed from dry to wet (workable) state. Add your powder to a bit of water, start mixing and gradually add more water till the right consistency is reached. This is the right way. Mixing the other way – wet to dry mixing – by starting with lots of water then gradually adding powder to the right consistency, is incorrect. Reason: excessive wetting weakens the plaster, alters its hydraulic set resulting in less performant, more friable and shorter lasting plasters.

Application: diluted to the right consistency, inject or pour it into the wall fabric to fill in any voids or cracks.

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).

MGN Certified Lime Structural Consolidation System

The MGN Structural Consolidation System is designed to strengthen masonry and vaulted structures using lime-based structural mortars, reinforced with glass fibre mesh and connectors. It combines traditional lime mixes with modern reinforcement to create a continuous structural layer across the surface of the wall.

Unlike concrete-based systems, which are dense, rigid and often too strong for historic masonry, this system is built around materials that are very similar to the original fabric. Lime mortars are more flexible, more accommodating of movement, and able to absorb and redistribute stresses rather than forcing them into the masonry.
