Description and uses of the product

SOPRALASTIC RAPID is a deformable, ultra-fast setting, two-component cementitious membrane, suitable for waterproofing and protection against efflorescence of concrete and other surfaces.


Thanks to its ultra-fast setting (passable in 2 hours), it allows the placement of ceramic tiles and stone material in places with permanent humidity, such as showers, bathrooms and sanitary rooms

in public and industrial areas with built-in drains.


It is a fiber-reinforced membrane, which presents a high resistance to positive and negative hydrostatic pressure.


“Fiber reinforced membrane”


Designed for waterproofing even below the water table, its most common applications being the waterproofing of swimming pools, ponds, water tanks, fountains, etc.

It can also be used to waterproof walls with small cracks and on other surfaces subject to strong temperature changes.


Once installed, it protects surfaces subject to the action of water and other external aggressions (ice, de-icing salts, chlorides, sulphates, carbon dioxide, etc.)


It is easily applied with a trowel, brush or roller, and can later be coated with all kinds of mortars, ceramics, paints, etc.
