Osmocem RD
Osmocem RD synergistically brings together properties and benefits derived from the peculiar mix of components, which include superpozzolanic reactive fillers, for a net improvement of the chemical inertness and adherence, the reduction of porosity and permeability, with consequent reduction of carbonation. Suitable polymers present in the mixture also increase its deformability and stability, reducing scraps, detachments and cracks.
Fields of application
Coatings, reconstructions and millimetric shields, finishing coats etc., in interventions to restore conservative, waterproofing works in reinforced concrete, wall coverings, extended exposed surfaces 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). Particularly indicated for interventions of dehumidification and anti-condensation rehabilitation of underground spaces, in combination with the dehumidifying cycle with Caleosana.
Allowed supports
Concrete
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". 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. After mixing is completed wait a few minutes and stir again before proceeding with application.
To further improve the performance of the coating, insert a steel reinforcement mesh (wire 2 mm mesh and 5x5 cm) between layers.
