Active Elements - Surface Etch is a concentrated phosphoric acid-based etching solution with specialty additives that has been developed to safely prepare concrete surfaces before applying stains and sealers. Active Elements - Surface Etch gently removes topical laitance and creates a porous surface to increase the penetration of concrete stains and sealers. It produces minimal fumes, is biodegradable and safe for use near grass and plants.
