Oil based paint containing lead compounds is removed from a substrate on which it is deposited by application of an aqueous solution thereto. The solution comprises a solvent that does not dissolve the paint and is compatible with water, a film former for retarding evaporation; a viscosity builder to fortify the solution and prevent slumping thereof during application to vertical and overhead horizontal surfaces; an alkaline compound for reacting with the pigment portion of the paint. Advantageously, the solution penetrates the deposited paint, which coagulates and separates from the substrate. Stripping procedures are facilitated, and neutralization of the substrate prior to repainting is avoided. A safe and effective treatment of materials covered with lead-containing paint is carried out in an economical. cost efficient manner.
Le décapage de peinture au plomb déposées sur un subjectile s'effectue par application d'une solution aqueuse. Ladite solution comporte: un solvant compatible avec l'eau et ne dissolvant pas la peinture, un générateur de pellicule retardant l'évaporation, un viscosifiant renforçant la solution et l'empêchant de couler pendant son application sur des surfaces verticales ou des plafonds et un composé alcalin réagissant avec les pigments de la peinture. La solution pénètre la peinture qui se coagule et se sépare du subjectile. Les opérations de grattage s'en trouvent facilitées et il est inutile de procéder à la neutralisation du subjectile avant de repeindre. C'est donc là une manière économique de traiter les surfaces recouvertes de peinture au plomb.
