Abstract
The invention relates to a gel for removing a graffiti from a surface of a solid substrate, consisting of a colloidal solution comprising an inorganic viscosifying agent, at least one solvent, optionally at least one surfactant, and optionally at least one dye and/or pigment. The invention also relates to a method for removing a graffiti from a surface of a solid substrate, wherein the gel is applied to said surface.
Claims19
A method of removing graffiti on a surface of a solid substrate, wherein at least one cycle is performed comprising the following successive steps:
- a) applying a gel to graffiti on the surface of a substrate, said gel consisting of a colloidal solution, said colloidal solution consisting of:
- 0.1 to 30 mass % relative to the total mass of the gel of at least one inorganic viscosifying agent;
- 70 to 99.9 mass % relative to the total mass of the gel of a mixture of ethyl acetate and diethyl malonate or a mixture of ethyl acetate and methyl acetoacetate;
- optionally, 0.1 to 2 mass % relative to the total mass of the gel of at least one surfactant;
- and, optionally, 0.01 to 10 mass % relative to the mass of the gel of at least one dye and/or at least one mineral pigment;
- b) removing the graffiti by maintaining the gel on the surface at least for a sufficient time so that the gel dries and forms a non-powdery, dry
- c) removing the dry solid residue from the surface of the solid substrate.
