RK 621 G Plasterer's Tape - 25 mm x 33 m

RK 621 G plasterer's tape – 25 mm x 33 m at a glance

The RK 621 G plasterer's tape from Krückemeyer is a single-sided adhesive PVC plasterer's tape particularly suitable for covering and masking during plastering and filling. At 25 mm wide and 33 m long, it provides sufficient covering length with few material changes. The backing consists of flexible PVC, while the rubber adhesive provides good adhesion to typical substrates such as plaster, concrete or drywall.

The core dimensions of 76 mm ensure even winding and easy handling when unwinding. The yellow colour makes covered areas easier to see. Its thickness of 0.12 mm provides a good combination of adhesion and flexibility. Temperature resistance ranges from -30 °C to +60 °C, making it suitable for varied applications, including cooler or warmer working environments.

Suitable uses in plastering and painting

When masking edges, joints and surfaces during filling and painting, the embossed yellow colour creates clear boundary lines. The single-sided adhesive surface enables quick positioning without the tape slipping, and adhesion remains stable even on slightly damp surfaces.
