Stampcrete Patina Stains
Composition and Materials
Stampcrete Patina Stains are a water-based formulation of hydrochloric acid and metallic salts. This formulation creates a reaction within the concrete substrate. This reaction slightly stains the concrete to provide deeper and more permanent color penetration.
Variations in ready-mix concrete, finishing techniques and stain application methods will affect final appearance – a test area is always suggested. Patina Stains will not hide existing concrete discoloration, blemishes, cracks or other surface problems.
