Product Description
What is CEMIMAX PP4?
CEMIMAX PP4 is a fast-drying cement-based patching compound designed for repairing, smoothing, and feather-edge leveling of interior subfloors prior to flooring installation or self leveling compound application. The compound forms a smooth, high-bond repair layer that prepares substrates for adhesives and floor coverings.
Where is it Used?
- Concrete and Plywood subfloors
- Engineered underlayments
- Gypsum substrates (with primer)
- Well-bonded existing flooring
- Correction of localized irregularities
- Prep before self leveling systems
Key Features
- Feather-edge to ½ inch thickness
- Ready for covering in ~15 minutes
- Smooth creamy consistency for troweling
- Strong adhesion to multiple substrates
- Low-VOC formulation
- Fast-track installation support

How is CEMIMAX PP4 Applied?
Mix the powder with the recommended clean water to achieve a lump-free viscous consistency, then apply using a trowel. Smooth the surface evenly and allow the compound to dry before installing flooring adhesives or self leveling compound systems. Do not add additional water after mixing.
Subfloor Preparation Requirements
Substrates must be clean, dry, and structurally sound. Remove contaminants by grinding, abrading, or vacuuming. Perform moisture testing according to applicable flooring standards before application.
Rapid Repair Context
CEMIMAX PP4 functions as a rapid-repair compound within the system, correcting substrate imperfections before the installation of primers, adhesives, and final coverings.
