Lime stucco
Designation
Lime stucco technique
Features
Since ancient times, stucco has been a mass-coloured lime-based plaster. It gives a smoother, more pleasing appearance.
Materials & Equipment needed
Ingredients: Pozzo nuovo lime putty, marble powder, water, pigments, casein predose (if necessary)
Tools: steel stucco trowel, stainless steel trowel, tadelakt roller, tadelakt spatula
Surface: walls
Application
Simplified stucco recipe: Mix the lime and marble powder 50% Lime – 50% Marble Powder with water until you obtain a ‘Fromage Blanc’ consistency. Mix the pigment previously (12 h) hydrated in water (thick cream) for better colour dispersion. You can add pigment for a stronger colour by adding a binder to fix the pigment (acrylic resin – casein, etc.). For better adhesion, lime additive can be added.
Preparing the surface: applying a lime primer
Lime undercoat 5 kg 5 kg for 50 m² (50 sq. ft.)
Odourless, low-VOC, semi-covering matt undercoat based on non-toxic, highly biodegradable chemical additives, selected quartz and premium quality silica sands bonded with acrylic resin emulsion.
Very good adhesion. Very easy to apply. Quick drying. Good resistance to atmospheric agents. Excellent water vapour permeability.
Particularly suitable for bonding all our interior and exterior lime-based finishes to non- lime-based substrates such as acrylic, vinyl or glycerol paints (gloss and satin to be sanded), plaster, painters’ plaster, concrete, etc.; or on old lime-based substrates that are slightly chalking.
Can also be used as a primer for mineral paints and coatings on poorly fixed substrates. Be careful with smooth paints, however, as this undercoat has a slightly rough appearance when dry.
FACIM25SF Facim SF bonding coat for fine coatings or Renodress 25 kg for 20m².
Partly composed of fat lime, natural hydraulic lime, special binders, mineral fillers premixed in the factory and additives specifically to improve its adhesion to all types of substrates. for levelling on new and old substrates, including those coated with old paints
– as an adhesion bridge or gobetis; on smooth concrete, thin and closed renders and glazed surfaces, as well as for the preparation and appropriation of substrates not initially compatible with hydraulic renders.
