RK 621 Plasterer's Tape - 50 mm x 33 m

Overview of RK 621 plasterer's tape – 50 mm x 33 m (40754)

RK 621 plasterer's tape from Krückemeyer is a single-sided masking tape made of flexible PVC with a rubber adhesive. With a width of 50 mm and a length of 33 m, it provides durable masking coverage for typical plastering or filling work. Its thickness is 0.12 mm, and the core has a diameter of 76 mm, making it compatible with common dispensing systems. The white colour provides good visibility on many substrates. The temperature range of -30 °C to +60 °C allows flexible use in workshops, on construction sites and in storage environments.

As part of the masking tape category and the RK 621 parent range, this plasterer's tape provides reliable adhesion to standard surfaces such as plasterboard, lime plaster and cement plaster. The combination of a flexible PVC backing and rubber adhesive supports predictable application even along irregular edges; the tape can be peeled off cleanly without leaving residue if removed in time.

Construction and material

Backing

The flexible PVC backing provides flexibility and reduces rippling during masking.

Adhesive surface

The rubber adhesive provides adhesion to gypsum and plaster substrates and allows clean removal.

Core and roll dimensions

The core has a diameter of 76 mm, suitable for common dispensing systems. The roll measures 50 mm wide x 33 m long.

Practical guidance

1. Apply the tape cleanly to the surface being covered and press it along the edges.
2. Apply filler to the area to be protected.
3. After filling or masking, remove the tape while the adhesive is still fresh.

Temperature and material characteristics

With temperature resistance from -30 °C to +60 °C, the tape retains its shape and adhesion even as temperatures change. The flexible PVC backing combined with the rubber adhesive provides reliable adhesion to typical construction substrates without damaging the substrate.
