Osmocem N
The action of the active components and of the adhesion promoters of Osmocem N, saturated by the reaction the support capillaries, forming a complex system of gel and stable crystals, which results in the best sealing, effective even in conditions of negative hydrostatic thrust, without hindering the breathability of the walls.
Osmocem N is compatible for food substances: is certified as suitable for the containment of foodstuffs and drinking water (Certificate no. 02/2010 Laboratorio Analysis Service di Settimo di Pescantina - VR).
Osmocem N waterproof test:
• Resistance to positive hydraulic thrust, UNI EN 12390/8: water penetration depth with 5 bar pressure = 1-2 mm (*)
• Impermeability to negative hydraulic thrust, UNI EN 12390/8 modified (concrete support a / c ratio 0.7): no passage of water with a pressure of 1.5 bar
(*) concrete with penetration depth <= 20 mm are considered waterproof
Fields of application
Waterproofing rigid structures and masonry walls underground, buried or in any case subject to water permeation: lift wells, basements, tanks, pipes, tunnels, garages, bridges, reservoirs, areas containing food, etc. in conditions of positive and negative hydrostatic thrust provided they are sufficiently porous and absorbent and free from any waterproofing and / or water-repellent surface treatment, whether chemical (siloxanes, epoxies, polyurethanes, etc.) or natural (wax-up).
Allowed supports
Concrete
Prefabricated concrete
Fiber-cement
Bricks
Mixed walls (bricks and stones)
Stone walls
Rock walls
Preparation of supports
Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., water repellent treatments in general, etc. conveniently saturated with water until they reach the condition "saturated with dry surface".
Mode of use
Pour about 2/3 of the mixing water into the mixer, add Osmocem N and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 19-20% (for interventions in the form of a spatula) or 21-22% (for interventions using a brush with long bristles). After mixing is completed wait a few minutes before applying. If applied by brush, roll out two or more crossed coats.
Although it is not a specific product for finishing thick coats, it can still be used for these purposes. In these cases, it is appropriate to use a fibreglass mesh Armaglass 160.
Application methods
Finishing trowel
Plastering machine
Brush
Spatula
Sprayer
