Lascaux Hydrosealer 750 is a 30% aqueous dispersion of pure acrylic, solvent-free and of extremely fine particle size with a pH value of 8. It is used as a impregnation sealer for consolidation of sanding or crumbling or otherwise not consolidated grounds. For consolidation of loose paint layers, crackings or cuppings. Can be used as a heat activated adhesive. After drying, Lascaux Hydrosealer 750 becomes insoluble in water like all acrylic dispersions, but remains reversible in acetone, alcohol and aromatics such as toluene and xylene.
