Filler KNAUF UNIFLOTT 5 kg — interior joint filler and finishing compound

KNAUF UNIFLOTT 5 kg is a ready-to-mix interior joint filler and finishing compound designed for sealing drywall and plasterboard joints, filling screw heads and repairing small surface imperfections on walls and ceilings prior to painting or wallpapering. The product comes in a 5 kg package and is formulated for both manual and mechanical application, aiming to create a smooth, even substrate for subsequent decorative finishes.

Advantages

UNIFLOTT provides good adhesion to gypsum-based boards and conventional plaster surfaces, producing a fine, smooth surface after sanding. The ready-to-mix powder simplifies on-site preparation and allows adjustment of working consistency for either hand or machine application. It is formulated to minimize shrinkage and cracking and sands easily to achieve a uniform finish suitable for painting or wallpapering.

Suitable for

• Filling and finishing joints between drywall and plasterboard panels
• Concealing screw and nail heads
• Repairing minor dents, chips and surface irregularities on interior walls and ceilings
• Preparation of substrates before painting, varnishing or wallpapering
• Use with manual trowels or spraying and pumping equipment for larger jobs

Key specifications

How to use

Mix the powder with clean water according to the manufacturer's recommended ratio until a lump-free, workable consistency is achieved. Apply the compound to clean, dust-free joints or defects using a joint knife, trowel or appropriate machine. For recessed joints or deep repairs, apply in layers allowing each layer to harden before applying the next. After the compound has hardened, sand lightly to obtain a smooth surface and remove dust before applying primer and the final decorative coating.

Usage recommendations

Store unopened product in a cool, dry place. Avoid application at very low temperatures or high humidity, and follow local ventilation and safety guidance when sanding. For best results, test the mix and application on a small area to confirm working time and finish before proceeding to larger surfaces.
