RK 621 Plasterer's Tape - 30 mm x 33 m

RK 621 plasterer's tape – 30 mm x 33 m at a glance

The RK 621 plasterer's tape is a single-sided adhesive masking tape with a flexible PVC backing and a rubber adhesive. At 30 mm wide and 33 m long, it provides robust coverage and reliable adhesion on smooth and slightly uneven surfaces. Its 0.12 mm thickness provides sufficient strength without compressing edges – suitable for masking edges and contours during plastering and painting. The white colour makes visual inspection easier during application. The 76 mm core size provides stable winding on standard rolls.

This tape belongs to the masking tape category and has good resistance to ageing and tearing, making it suitable for working environments where the masking must remain in place for longer periods.

Suitable for plastering and masking

Plastering

The flexible flexible PVC backing conforms neatly to irregular contours. The rubber adhesive bond provides robust adhesion to plastered and filled surfaces without adhering to overly warm surfaces.

Masking

The white, impermeable film provides clear coverage of surfaces. It unwinds neatly and can be removed without residue, saving time and reducing missed areas.

Construction: flexible PVC backing with rubber adhesive

The backing consists of flexible PVC, which provides good flexibility and lies evenly on the surface. The adhesive is a rubber binder that ensures reliable adhesion under moderate surface conditions.

Temperature resistance and application

The tape is designed for robust use under typical building-site conditions and remains flexible even with temperature fluctuations from -30 °C to +60 °C. This makes masking easier in cooler rooms and during work on warm façades alike.
