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 a 25 x 25 mm square mesh, made of alkali-resistant glass fibre containing > 16% zirconium dioxide, woven using the leno weave technique and coated with a thermosetting polymer. Mesh certified for preventing the detachment of infill panels from floor slabs; easy and quick to apply, manageable and simple
to cut. It combines low weight and reduced thickness with excellent mechanical properties in both the warp and weft directions. Resistant to atmospheric agents and aggressive environments, it provides durability to the composite systems in which it is used. Suitable for any substrate and fully compatible with both cement-based and lime-based mortars.

Flangia con vite
Nylon fixing flange (58 mm in diameter and 40 mm long) with a 30 mm galvanised steel self-tapping screw for connecting ARMAGLASS STRUCTURA meshes in the RINFOR SYSTEM 1 and 2 anti-delamination systems (refer to our RINFOR SYSTEM technical literature at https://www.groutpower.it/ )

Squadretta con tasselli
SQUADRETTA made of galvanised steel, supplied together with two nylon plugs and two galvanised screws for fixing the element to the substrate. The metal SQUADRETTA features five fixing holes on each side: one large hole for securing the plug and four additional small holes (for fixing the SQUADRETTA to wooden joists, if required). It is an essential fixing accessory for the RINFOR SYSTEM 1 and 2 anti-delamination systems.

Unisan
Composite, fiber-reinforced, consolidating mortar with low liquid water absorption, used for the structural rehabilitation of deteriorated historic or monumental masonry. It contains no substances potentially harmful to masonry and is composed of hydraulic binders free from soluble salts, pozzolanic silica, selected siliceous-calcareous aggregates, specific shrinkage-reducing agents, and alkali-resistant READYMESH fibers, which provide high flexural tensile strength and increase the mortar’s fracture energy. Ideal for the structural rehabilitation of historic brick, stone or mixed masonry, used in combination with ARMAGLASS STRUCTURA glass-fiber meshes.

Sanastof
Premixed mineral-based product formulated with NHL 3.5 natural hydraulic lime, pozzolanic microsilica, selected aggregates, high-toughness microfibres, and lightweight thermally insulating aggregates with a low elastic modulus. It is used for skim coating and levelling, both indoors and outdoors. It is perfectly compatible with a wide range of substrates: lime-based, lime-cement and cement renders, concrete, porous stone and masonry units. Its characteristics make it particularly suitable for green building applications and the restoration of historic and monumental buildings. The maximum aggregate size is 0.9 mm.
