RK 621 Plasterer's Tape - 38 mm x 33 m

Overview of Krückemeyer RK 621 plasterer's tape – 38 mm x 33 m

RK 621 plasterer's tape is a single-sided masking or plasterer's tape made of flexible PVC with a tacky rubber adhesive. At 38 mm wide and 33 m long, it is suited to masking surfaces and edges during plastering and filling work. The core measures 76 mm, and the tape thickness is 0.12 mm. The light white colour provides good visibility and clear definition.

The tape is temperature-resistant from −30 °C to +60 °C, making it suitable for typical construction and plastering conditions. The combination of flexible PVC backing and rubber adhesive provides good adhesion to surfaces without slipping beneath protected or visible areas.

Suitable for plastering and masking work

Surface masking during plastering

The tape can be applied neatly to surfaces and protects edges and previously plastered areas from dirt or paint. The smooth backing surface reduces tension during removal, helping to keep edge lines clean.

Masking edges

Good adhesion to the substrate and the visibility of the white tape allow edges to be masked precisely. When necessary, the tape can be removed without residue, minimising damage to sensitive surfaces.

Adhesive

The rubber adhesive provides long-term adhesion to plaster, tiles and wood substrates without failing prematurely.

Application tips

1. Align the tape from the dispenser or roll and cut it to the desired length.
2. Place the tape on the surface and press it down lightly, forming clean edge contours.
3. After completing the work, carefully lift the tape from the edge without damaging the surfaces underneath.
