Ameripolish 3D SP Stain Protector is designed to enhance the stain protection of newly polished concrete. This breathable, semi-penetrating finishing treatment creates a water-resistant barrier that prevents liquids from infiltrating the pores of the concrete and etching the surface. Built-in 3D densifier properties also help in hardening and dust-proofing the surface. Ameripolish 3D SP Stain Protector enhances both the natural color of the concrete as well as concrete that has been dyed. This semi-topical sealer contains UV stabilizers to prevent color dispersion and fading over time. Ameripolish 3D SP Stain Protector can be used in conjunction with your favorite dyes and densifiers. However, for optimum results, we recommend using it with Ameripolish 3D HS Densifier. This ready-to-use, low-VOC formula covers 2,000-2,500 square feet per gallon.
