Facade cleaner is an innovative, highly concentrated agent provided for cleaning of structural, mineral, acrylic and silicate plasters, concrete paving blocks, facades, roof tiles, elevation stones, bricks and clinker. Silver causes that the cleaned surface becomes resistant to biological blooms (fungi, algae, bacteria). It removes efficiently all the traffic dirt, microorganism blooms, paint and plaster residues and fresh graffiti. The cleaner applied in the form of an active foam extends the time it affects the cleaned surface, providing enhanced effects.
