OSMOCEM FLEX is certified for compatibility with contact and containment of drinking water and food substances (certificate n. 04/2010 of the Laboratorio Analysis Service di Settimo di Pescantina - VR).
Moisture-proofing concrete containment works (tubs, swimming pools, pipes, ducts, areas containing food, etc.). Moisture-proofing balconies, terraces, bathrooms, showers, etc., prior to laying successive plasters and screeds, ceramic coatings 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). Waterproofing coating of earth-retaining masonry, micro-cracked plaster. Deformable finishing coats in general.
Application surfaces should be clean and free of dust, soiling, crumbling and non-adhering parts, etc., water repellent treatments in general, etc. conveniently saturated with water until they reach the condition "saturated with dry surface".
Any cracks from plastic or hygrometric shrinkage present should be preliminarily treated with appropriate products and techniques. In the case of extended coating surfaces you must provide appropriately placed "chimney flues" for venting steam.
OSMOCEM FLEX comes in two predosed components that must be thoroughly mixed, with mixers with a low number of revolutions (maximum. 300 Revs/minute) until a homogeneous lump-free mixture is obtained. While the addition of other ingredients should be absolutely avoided, it is possible to moderately correct the consistency, as required, by adding water up to a maximum of 8%. Water must be added when the mixture is ready, continue to mix until the optimal homogeneity is obtained.
When waterproofing terraces and balconies, two coats, each about 1.5 mm thick (2.2 kg/m² per coat), of OSMOCEM FLEX should be applied, each coat should be applied when the previous one looks stable (at least 4 hours later at 20°C). It is recommended to interpose the fibreglass alkaline-resistant mesh ARMAGLASS 160 in the thickness of OSMOCEM FLEX, between the first and second coat. The self-adhesive butyl band PROBAND should also be placed between the floor screeds and the elevation walls. Finally, it is advisable to place the special elastic band ELASTOTEX 120 or ELASTOTEX 120 CLOTH, at any expansion joints, securing it with the same OSMOCEM FLEX.

Do not use OSMOCEM FLEX on strongly degraded or non-adhering supports , since it would reduce the waterproofing quality.
Do not apply on little or non-porous substrates or previously coated with water-repellent treatments in general, if not after appropriate roughening by bush hammers, sanders and equipment suitable for preparatory treatments of substrates, or after appropriate treatment with suitable polymeric primers.
Monocomponent, osmotic cement mainly used to fill and waterproof the cavities in a concrete wall having removed the protruding part (excess) of the formwork spacers.
Two-component, osmotic cement, certified for drinking water and EN-14891. Moderately deformable, highly resistant and adhesive, it is a multi-use product. Resists traffic, UV rays, ideal for reinforced finishing coats. Azichem's bestseller!
Hard, monocomponent, osmotic cement. Highly resistant and adhesive. Specifically for the construction of reinforced, impermeable and thick grout, both in thrust and counter-thrust.
Hard, monocomponent, osmotic cement, certified for drinking water. Very adhesive and easy to apply. It is a classic osmotic mix, efficient and cheap!
Two-component, osmotic cement, slightly deformable. To use thick, both in thrust and counter-thrust. It is the evolution of the OSMOCEM MR, easier to apply and more adhesive. Recommended!
Hard, monocomponent, osmotic cement with a natural hydraulic lime base. It is an ideal product for waterproofing in positive thrust, in the restoration and recovery of old buildings.
