IZONIL Hard: hydrophobic and simultaneously vapor-permeable render of a new generation

The development of construction materials is constantly moving forward, including plasters. The product IZONIL Hard, developed and manufactured in Slovakia, represents a dry, industrially produced plaster that is hydrophobic due to its world-unique composition, while also being highly vapor permeable and exceptionally effective at drying.



In situations where water infiltrates a house (for example, during floods or due to heavy rainfall), serious structural problems or health complications caused by mold growth may arise. For the product to be effective in combating these unwanted complications, it is not enough for it to be merely water-repellent. Its functionality is significantly influenced by its vapor permeability. Both requirements are met by the plaster IZONIL Hard, which primarily consists of Portland cement, silica sand, and a unique additive called Izocomponent. It is reinforced with PP fibers and can be used in both interior and exterior applications. The plaster is non-toxic (suitable for direct contact with drinking water) and can also be applied to damp surfaces. Application can be done manually or with a plastering machine, and due to the excellent adhesion of this plaster, minimal waste is produced during its application.

Universal Application

The plaster can be used on vertical substrates (brick, aerated concrete, and roughened concrete walls), horizontal substrates (concrete floors and roofs), waterproofing and remediation of basements and other underground spaces, during the renovation of plasters in old buildings, waterproofing of bathrooms and shower stalls, and also as a means to prevent water from seeping between floors. The IZONIL Hard plaster is invaluable for its versatility, quality, and reliability in nearly any construction. It is manufactured in two standard variations: F010 Fine (grain size 0-0.6 mm / 25 kg) and C020 Coarse (grain size 0-2 mm / 25 kg).
