Feuchtestopp

düfa Feuchtestopp is used for the impregnation of wood and mineral building materials (e.g., all types of surfaces made of concrete or plaster, brick masonry, natural stones, artificial stones, fibre cement and aerated concrete). It operates on these substrates as a water repellent and hardening primer before coatings with emulsion paints, silicone resin paints and PU lacquers follow. Due to a colouring agent it appears during application as a yellow film so that the already painted areas are clearly visible.
