UNISAN

Dehumidifying structural, reinforcing, grey cement plaster

Code: RNF.0199

Components: 1

Appearance: Powder

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.

Consumption

Approximately 15 kg/m² of UNISAN for every centimetre of thickness to be implemented (approximately 1500 kg per cubic metre).

Use fields

Construction of plasters and reinforced slabs in interventions of restoration, construction of plaster and dehumidifying coatings with high performance, bedding of bricks and modular elements.

Preparation of supports

The surfaces should be clean and free of any soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition of "saturated dry surface".

In the case of structural reinforcing slabs, you will need to proceed with applying an appropriate reinforcing electrowelded mesh, to be fixed with PROFIX, GROUT MICRO-J, REPAR TIX G2 or SYNTECH IC 55.

Use method

Pour about 2/3 of the mixing water into the mixer, add UNISAN and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 12-14% of the weight of the bag. After mixing is completed wait a few minutes before applying. Apply the product by plastering trowel and brick trowel, or preferably with plastering machine (type PFT model G4).
Do not apply in case of direct exposure to sunlight or excessive ventilation. Cure the protection and the prolonged moist hardening, of exposed surfaces.
