SM25 LimeLine Washi Ecomask
Tenacious LimeLine Washi Ecomask
SM25 is a medium-grade Washi masking tape with a thin, flat, dense rice paper backing coated with an emulsion acrylic adhesive system. Engineered for precision edge work, it delivers sharp, crisp paint lines with zero bleed on smooth surfaces — making it the professional’s choice when performance counts.
The LimeLine name comes from the high-visibility lime green backing — a practical feature that lets trade painters write instructions directly on the tape, mark defects for rectification, and identify areas clearly on site. Unlike standard masking tapes, SM25 holds its adhesion and clean-removal properties through low-bake oven cycles to 120°C and UV exposure for up to 60 days outdoors.
SM25 is built for trade painters and quality finishers, two-pack and spray painters, auto finishing and low bake ovens, marine and boat builders, and caulking and sealing applicators. It handles both interior and exterior applications — eliminating the need for separate products across different jobs.
Product Features
Ultra-Thin Precision
The ultra-thin, flat, dense Washi backing creates razor-sharp masking lines. Sits flush against surfaces — no raised edge, no bleed on smooth substrates.
Oven Safe to 120°C
Thermal stability to 120°C makes SM25 safe for low bake auto finishing ovens. Holds clean edges through heat cycles and removes without residue after.
60-Day UV Stability
UV stable for up to 60 days outdoors. Removes cleanly without adhesive residue for up to 60 days outdoors — the go-to for exterior work, marine, and boat builders.
Key Markets & Applications
Precision masking for trade painters, auto finishers, marine & boat builders, caulking applicators, and silicone bead masking on glass and smooth surfaces.

Trade Painting & Auto Finishing
The professional’s tape for quality finishers — sharp edges, clean lines, and oven-safe performance through low bake auto cycles. Handles two-pack and spray painting without solvent bleed.
Exterior Painting & Window Finishing
UV stable for up to 60 days outdoors — ideal for exterior brush work, window frames, trims, and weatherboard. Clean removal without residue, even after extended outdoor exposure.
5 Key Benefits of SM25 LimeLine
Strips Without Breaking
Very strong rice paper backing means SM25 peels back in one clean pull — no snapping mid-strip, no torn tape left on the surface.
Safe on Delicate Surfaces
Suitable for use on many delicate finishes — removes cleanly without lifting, marking, or damaging the substrate underneath.
No Solvent Bleed
Emulsion acrylic adhesive resists solvent-heavy paints and two-pack coatings — no bleed through, less masking cleanup, and paint stays on the tape on removal.
One Tape, Every Application
Interior brush work, two-pack spray painting, low-bake auto ovens, exterior masking, caulking and sealants — SM25 handles all of them, removing the need for multiple masking products.
High-Visibility & Writeable
Lime green backing is easy to spot on any surface. Write instructions, mark defects for rectification, or identify areas on site — without extra materials.
What Makes it Different
SM25 LimeLine combines an ultra-thin Washi paper backing with an emulsion acrylic adhesive system specifically engineered for precision masking. The thin, flat, dense paper sits flush against surfaces, eliminating the raised tape edge that causes paint bleed on standard masking tapes — the result is a cleaner line with less cleanup.
The lime green colour is not cosmetic — it’s a working tool. High visibility on every surface means trade painters can write job instructions directly on the tape, mark defects for rectification, and track which areas are ready. One tape handles interior brush work, two-pack spray painting, low-bake auto ovens, and 60-day exterior marine masking — replacing the need for multiple masking products across different applications.
