Osmocem D
Osmocem D is extremely easy to apply, error-proof. It induces adherence to supports by mechanical adhesion and osmotic diffusion. It is also effective in terms of negative hydrostatic thrust (negative pressure).
Osmocem D is compatible with food substances: it has been certified as suitable for the containment of foodstuffs and drinking water (Certificate no. 03/2010 Laboratorio Analysis Service di Settimo di Pescantina - VR).
Ivory color available on request.
Fields of application
Waterproofing treatments of underground structures and masonry, pools, tanks, pipes, tunnels, garages, bridges, reservoirs, basements, areas containing food, etc., 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). Suitable in both positive or negative hydrostatic thrust conditions. It can also be used for waterproofing terraces and balconies.
Allowed supports

Floor screed
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". It is always advisable to prime the application support with approximately 100-150 g / m2 of COMPONENT B adhesive latex; in this way, at least three extraordinarily effective operations are carried out with a simple and fast priming: a) expulsion of the air from the surface porosity _ stopper (with a drastic reduction of the well-known blistering that occurs on elastic products with low thickness); b) decrease in the absorption of the support (to guarantee a suitable curing of the waterproof skim coat); c) increased adhesion thanks to the deep penetration of the polymeric component.
Mode of use
Mix the powder component (component A) with the hydrating solution (component B) with a drill at a low number of revolutions, pouring the powder progressively in the liquid, continue mixing until a homogeneous lump-free mixture is obtained. Moderate variations in the amount of component B in the mix are allowed, to obtain a more or less fluid compound depending on the intended use (for example, if applied with a brush more component B is required compared to as usage as easy to spread plaster). After mixing is completed wait a few minutes and stir again before proceeding with the application. Mix at a ratio of 25 kg of component A with 5.2 litres of component B.
To further to improve the performance of the coating (for example in the case of waterproofing of terraces and balconies), insert the alkaline-resistant fibreglass reinforcing mesh Armaglass 160 between layers, for a general consumption of about 5 kg/m².
