Information ARDEX K 22 F™
Choose Fiber Reinforced
Suitable Substrates
- Concrete (structurally sound)
- Absorbent terrazzo on concrete†
- Patching, leveling or fill materials
- Plywood subfloors
- Solid hardwood†
- Gypsum††
- Properly installed ARDEX moisture control systems on concrete:
- ARDEX MC™ RAPID
- ARDEX PU 50™
- ARDEX VR 98™
- Other approved, non-porous materials on concrete†:
- Epoxy terrazzo; non-porous (non-absorbent) cementitious terrazzo
- Ceramic, quarry or porcelain tiles
- Epoxy coatings
- Non-water-soluble adhesive residue
- Concrete treated with certain curing compounds (test areas only; for full instructions, see www.ardexamericas.com/properprep)
†Must be sound, solid and well-bonded to underlying, structurally sound substrates.
††Please be advised that gypsum is inherently weak. This product will provide a solid bonding surface for new flooring, but it cannot correct the weakness of an underlying gypsum surface.
Suitable Applications
- Above-grade
- On-ground substrates that have been treated with a suitable ARDEX moisture control system
- Dry areas only
- Interior applications only
Key Features
- Levels and smooths interior, above-grade substrates: Concrete, gypsum, wood, VCT, existing patching and leveling materials and non-water-soluble adhesive residue on concrete
- Excellent for challenging substrates
- Installs up to 1 1/4” (3 cm) neat, 2” (5 cm) with aggregate in most applications
- Pourable or pumpable
- Walkable in 2 to 3 hours
- Install floor coverings in as little as 24 hours
