Calcina Fine MGN - Description

CALCINA FINE MGN is an extremely breathable premixed natural white lime finish with good adhesion, based on very high-purity air lime (over 90% calcium hydroxide) and a small percentage of natural white hydraulic lime.

The richness of the mix makes it possible to achieve thicknesses unimaginable with ordinary common fine mortar. It can be applied by hand or by a plastering machine.

Old Cottage Wall Replastering

This old cottage has been suffering from rising damp for quite a while. As a result the internal plastering has been blown. The long-time fix involves the replastering of the wall with the Rinzaffo MGN Roman salt-resistant base coat, providing a building-friendly fix for several decades.

Application

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

Finishing

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.

Recommended thickness of the finish: 3-4 mm. For best results, the finish should be applied in two “half-coats” of 2 mm each, with a fine 3-4 mm fibreglass mesh embedded in-between. The mesh makes the finish more flexible, minimizing the appearance of fine cracks.

Various textured finishes can be achieved, depending on the finishing technique used:
- Coarse finish: by finishing the surface with a sponge or wooden trowel.
- Smooth finish: by using a stainless steel trowel, compressing and smoothing the semi-dry surface, the sand granules are pushed into the material, resulting in a smooth finish.
- Washed finish: by finishing the surface with a sponge trowel. After the surface has hardened, the surface is washed with water and blotted with a sponge to bring out the aggregate, its specific texture and colour.

Painting: as this is a breathable lime plaster, wall surfaces should be painted with a breathable mineral paint. Wallpapers and modern emulsion petrol-based paints, with no or limited breathability, should be avoided.

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).
