DCP Fosur 74 is a strong acidic cleaner that effectively removes rust stains, grout residue, mortar smears, cement haze, efflorescence, and limescale. It’s also suitable as an etching agent to prepare concrete surfaces before applying paints, adhesives, or coatings.
This water-based formula combines surfactants, emulsifiers, and phosphoric acid to deliver deep cleaning power with controlled acidity. The 10L size is ideal for home renovation projects, small-scale contractors, and professional maintenance tasks.

Usage instructions
Protection: Wear rubber gloves and eye protection.
Test First: Test a small area and wait 24 hours to ensure desired results.
Pre-Wet: Pre-wet the surface before applying the cleaner, except before etching.
Dilution: Depending on the cleaning task, dilute the cleaner up to 0.5% or use in pure form.
Application: Apply the solution, allow it to sit for 2-5 minutes, and agitate with a hard brush or scrub pad to loosen stains. Do not let the solution dry on the surface.
