Description
Blue Dolphin Washi masking tape is designed to meet the high quality requirements of even the most demanding painting projects. The tape is made of traditional Japanese washi rice paper, known for its exceptional thinness and durability. This material gives the tape extremely precise edge conformity, which stops paint getting under the tape (so-called paint bleed). The result is razor-sharp, perfectly straight paint lines, which are essential in high-quality finishing work.
The tape has a high-quality acrylic adhesive optimised to adhere reliably to almost all surfaces found on construction and renovation jobs. The product is suitable for use in interior and exterior painting alike, and it withstands sunlight and changes in the weather excellently. The manufacturer guarantees an exceptionally long clean removability of up to 60 days. This means the tape can be left on the surface for two months and still comes off in one piece without leaving adhesive residue or damaging the substrate.
Blue Dolphin Washi tape is suitable for many different materials. It works excellently on painted walls, wooden trims, glass surfaces, metal and plastic. The thin profile of the tape also makes it an ideal choice for demanding decorative painting, two-colour lines and other tasks that require precision, where you do not want the edge of the tape to leave a “step” in the paint surface. The product is designed for use with both water-based and solvent-based paints.
Intended use:
-
Precision painting and sharp masking The thinness of the washi paper is the key advantage of the product when you are aiming for a perfect masking line. The tape presses tightly onto the substrate, so paint cannot bleed under it. This makes it the first choice for decorative painting, making stripes and precisely separating surfaces of different colours.
-
Long-term protection indoors and outdoors The tape’s 60-day UV and weather resistance gives significant flexibility in work. Protection can be put up well before painting starts, and the tape withstands the drying times of several coats of paint without coming loose or the adhesive hardening. This is a big advantage especially in large projects and exterior painting, where weather conditions can delay work.
-
Versatile use on different surface materials The adhesive formulation of the tape is balanced so that it gives sufficient hold on most surfaces without damaging them. It is safe to use, for example, on cured paint surfaces, varnished wooden parts, window glass, aluminium profiles and vinyl surfaces, which reduces the need for several different tape grades on site.

Instructions for use:
To ensure the best adhesion and result, the surface to be taped should be clean, dry, dust-free and grease-free. Press the tape carefully onto the substrate, especially along its edges, using a spatula or fingertip, for example. This ensures tight contact and stops paint getting under the tape.
The tape can be left on the surface for up to 60 days. Remove the tape by pulling it calmly and evenly at an angle of about 45 degrees to the painted surface. For the best result, it is recommended to remove the tape when the paint is touch dry but not yet fully cured. This helps prevent the new paint film from tearing off with the tape.
Warnings:
-
Although the tape is designed to come off most surfaces cleanly, we always recommend testing the suitability of the product on a small, inconspicuous area before wider use, especially on very delicate, old or porous surfaces.
-
Do not use the tape on fresh, newly painted surfaces that have not fully cured. Follow the paint manufacturer’s instructions on curing times.
-
Although the tape withstands UV radiation for 60 days, extreme conditions (very strong sunshine and heat) can affect removability.
Frequently asked questions (FAQ):
What is washi tape?
Washi tape is made of Japanese rice paper. It is considerably thinner than traditional crepe paper masking tape, which allows much more precise, sharper paint lines, because paint cannot “climb” against the edge of the tape.
Can this tape be used outdoors?
Yes, Blue Dolphin Washi is UV protected and weather resistant. It can be used safely in exterior painting, and it comes off cleanly even after 60 days of exposure.
Why choose washi tape instead of ordinary masking tape?
Washi tape is the right choice when the highest possible quality and precision in masking are needed. Its thinness stops paint bleeding, and the long clean removal time gives flexibility in work compared with ordinary tapes, which have to be removed sooner.
Recycling instructions:
-
Tape roll: Used masking tape contains adhesives and possibly paint residues, so it is typically sorted as mixed waste or energy waste according to local rules.
-
Core: The cardboard core of the tape roll is recyclable cardboard and should be sorted for cardboard collection.
-
Packaging: Any plastic wrap is sorted for plastic collection and the paper label for paper or cardboard collection depending on the material.
