Overview

tesa® Precision Mask® 4334 is a high-grade professional painting tape engineered to deliver razor-sharp, clean paint edges on smooth and slightly textured surfaces. Combining a supple washi paper backing with a perfectly balanced acrylic adhesive, it adheres flush to surfaces to prevent paint bleed and paint tears - eliminating the need for costly touch-up work.

Suitable for both indoor masking for up to 6 months and outdoor masking for up to 8 weeks, tesa® 4334 is designed for high-quality painting, lacquering, and spray painting work. Its heat resistance of up to 150°C makes it suitable for spray painting applications followed by oven drying at up to 120°C for 30 minutes. The thin, low-elongating backing makes it ideal for two-tone applications and long, straight lines where precision is essential.

With very good hand tearability, constant adhesive strength, and easy, clean removal, tesa® Precision Mask® 4334 is the trusted choice for professional painters and decorators where a flawless finish is non-negotiable.

Application

• Ensure the surface is clean, dry, and free from dust, grease, and contamination before applying the tape
• Unroll the tape and apply firmly along the masking line, pressing down the edges with a finger or squeegee to ensure full contact with the surface
• For two-tone or long straight lines, apply the tape in sections, overlapping slightly and keeping the line consistent
• Apply paint or lacquer as required - the tape is suitable for brush, roller, and spray application
• For spray painting with oven drying, ensure oven temperature does not exceed 120°C for 30 minutes
• Remove the tape at a 45° angle while the paint is still slightly wet for the cleanest edge, or once fully dry - do not leave beyond the recommended masking period
• Remove slowly and steadily to avoid tearing or lifting the paint film

Aftercare & Storage

• Remove the tape within the recommended masking period — up to 6 months indoors and up to 8 weeks outdoors
• Do not leave the tape in place beyond the recommended period as adhesive residue may become harder to remove
• Inspect paint edges after removal and allow the paint to cure fully before any further work

Storage

• Store unused rolls in a cool, dry place away from direct sunlight and heat sources
• Keep in original packaging to protect the adhesive from dust and contamination
• Avoid storing in areas of high humidity which may affect adhesive performance
