DCP Fosur 74 is a powerful acid-based cleaner developed to remove rust stains, mortar and grout smears, cement haze, efflorescence, and mineral deposits. It also acts as an etching agent, preparing concrete for coatings and adhesives by creating an optimal surface profile.
This high-performance, water-based blend of surfactants, emulsifiers, and phosphoric acid ensures both deep cleaning and surface preparation. The 25L format offers great value for frequent users and small professional teams.

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.
Removal: Use a clean mop or wet vac to remove the solution, then rinse thoroughly with clean water.
Neutralize: Before applying any sealer or coating, neutralize the surface with DCP Biomex HDI and let it dry thoroughly.
