APPLICATION PROCEDURES
- Follow the instructions described from point 1) to point 4) of the RINFOR SYSTEM 1 ;
- Remove the existing plaster on the masonry close to the beam (or the floor), for a width of 10 cm;
- Dust the carving surface and wash it with low pressure water;
- Complete the intervention by incorporating and covering the ARMAGLASS STRUCTURA 250 mesh with a centimeter layer of UNISAN* composite mortar, fiber-reinforced with double type of READYMESH fibers (glass and polypropylene), dehumidifying, very high breathability, class R (restoration according to UNI EN 998/1), based on hydraulic binders with a low content of soluble salts, with mechanical resistance in class R2 (according to UNI EN 1504/3), reaction to fire class A1 (EN 13501-1), permeability to water vapor 11 μ (UNI EN 1015-19), compressive strength after 28 days > 20 N/mm² (UNI EN 12190), flexural strength after 28 days > 5MPa (UNI EN 12190), elastic modulus 11 GPa (EN 13412), maximum particle size of the aggregate 1.5 mm; mix the mortar with water according to the proportions indicated in the technical data sheet, continuing the mixing for at least three minutes and in any case until a homogeneous, creamy and lump-free mixture is obtained; laying the mortar manually or by spraying (with a suitable sprayer for fiber-reinforced mortars), taking care to perfectly cover the surface of the substrate, without gaps or shaded areas; thickness of the mortar from 1 to 2 cm approximately. Consumption of about 15 kg/m²/cm thickness;
- Regularize the surface of the mortar avoiding excessive smoothing to leave the surface slightly rough with sufficient grip for the subsequent skim coat; wait for the mortar to cure properly before proceeding with skim coat;
f. two-coat smoothing performed with SANASTOF premix of mineral composition, based on natural hydraulic lime NHL 3.5, microsilica with pozzolanic activity, selected aggregates, high tenacity microfibers, light heat-insulating aggregates with low modulus of elasticity; consumption of about 3 kg/m² for two applied coats and a total thickness of 2-3 mm; - Finish the surgery with a highly breathable colored finish using products from the SANAXIL or PROTECH SIL line
* as an alternative to UNISAN mortar, the super adhesive RASOCOAT mortar can be used, based on hydraulic binders, water-dispersible resins, silico/limestone aggregates and specific agents. Main technical characteristics of RASOCOAT mortar: Adhesion bond (UNI EN 1015-12): > 1.5 N / mm²_ Density: 1.90 kg / l _ Compressive strength after 28 days (UNI EN 1015-11): > 20 N / mm² _ Flexural strength after 28 days (UNI EN 1015-11): > 6 MPa

SYSTEM COMPONENTS
Armaglass Structura 250
280 g/m2 structural reinforcement mesh with 25 x 25 mm square mesh, in alkali-resistant fibreglass, containing >16% zirconium dioxide, constructed with a leno weave and primed with thermosetting polymer. Certified mesh for the anti-detachment of flooring; easy and quick to apply, to handle and to cut. It combines lightness and thinness with excellent mechanical characteristics in the warp and weft. Resistant to atmospheric agents and aggressive environments, conferring durability to the composite systems in which it is used. Suitable for any substrate and perfectly compatible with both cement-based and lime-based mortars.

Unisan
A composite mortar that is fibre-reinforced, consolidating, dehumidifying, grey in colour and utilised for the structural restoration of crumbling old or monumental masonry. It contains no substances that are potentially harmful to masonry and is composed of NHL 3.5 natural hydraulic lime and hydraulic binders free from
soluble salts, along with silicas with pozzolanic activity, selected siliceous-calcareous aggregates, specific shrinkage-reducing agents and resistant alkaline READYMESH fibres that confer high flex-traction whilst increasing the performance of the mortar’s fracture energy. In conjunction with ARMAGLASS STRUCTURA fibreglass mesh, it is ideal for the structural restoration of old walls or crumbling constructions.

Sanastof
A premix with a composition of breathable minerals for dehumidifying, with a base of natural hydraulic lime NHL 3.5, microsilicas with pozzolanic activity, selected aggregates, high tenacity microfibres and inert light unit weight thermal-insulating aggregates with a low elastic modulus. It is used for skimming and smoothing, both indoors and outdoors. This product is perfectly compatible with multiple substrates: lime-based plasters, lime cement, cementitious mortars, concretes, porous stone and brick. Its characteristics render it particularly suited to green building works and for restoring historic and monumental constructions. The maximum grain size of the aggregate is 0.9 mm.
