Proline Dura-Etch

Description

Proline Dura-Etch is a concentrated, acidic cleaning solution that produces a light etch.  The material uses phosphoric acid to lightly etch the surface and remove mild efflorescence.  Using phosphoric instead of muriatic acid gently increases the porosity of the surface without damaging the substrate chemicals necessary for subsequent acid staining, thereby allowing better penetration of the stain solution.
