Appearance: Powder + Liquid
An osmotic two-component cement compound for waterproofing with the addition of specific flexible polymers, it is plastic-deformable and resistant even with counterthrust to render impermeable concrete works, roofing, pools, cracked plaster, elevator compartments, balconies, terraces, and more. It can also be used for repairs and protective coating of hydraulic works and marine structures or in aquatic atmospheres.

OSMOCEM iTOP is characterised by an extreme ease of application, being veritably fool-proof. It permits adherence to supports for mechanical adhesion and osmotic diffusion. It is also effective in conditions of negative hydrostatic thrust (counterthrust) and is applicable as a coating in rooftop gardens and planters due to its resistance to the mechanical action of roots.
Approximately 1.6 kg/m² of OSMOCEM iTOP for each millimetre of thickness to be made.
Waterproofing treatments for underground structures and masonry, swimming pools, tubs, planters, rooftop gardens, ducts, tunnels, pits, bridges, tanks, basements, food containment areas and so on whereby sufficiently porous and absorbent, being free from any water-resistant and/or water-repellent surface treatment, be it chemical (siloxanes, epoxy, polyurethane, etcetera) or natural (waxing). Suitable for both positive and negative hydrostatic thrust conditions, it can also be used for waterproofing terraces and balconies.
The applicative surfaces must be clean, free from contamination or any loose or detached parts, dust, water-repellent treatments in general, and so on, being suitably watered down until it is “saturated with a dry surface”.
Mix the powder (component A) with the hydrating solution (component B) using a drill at low-speed or other effective mechanical mixer, gradually adding the powder to the liquid. Continue mixing until reaching a homogeneous and lump-free mixture.
After mixing, wait a few minutes then stir again before applying.
To further improve the effects of the coating (for example, when waterproofing terraces and balconies), it is advisable to add the ARMAGLASS 160 alkaline-resistant fibreglass reinforcing mesh between one layer and the next, for a consumption of around 3-4 kg/m2 as a guideline.
Do not apply in the presence of direct insolation or when dealing with wet curing and protection.
Do not apply to substrates with little to no porosity or those previously coated with water-repellent treatments generally, except whereby following proper roughening by means of bush hammering machines, sanders or equipment suitable for preparatory surface treatment or specific treatment with suitable polymer primers.
