What EDGE RED is made for.

According to the data sheet, EDGE RED was developed primarily for outdoor use. Recommended for:

  • Exterior render and textured render
  • Concrete and masonry outdoors
  • Timber facades and cladding
  • Windows and doors outdoors, balconies and terraces
  • Slightly damp surfaces, for example morning dew
  • Automotive and industrial coating (up to approx. 150 °C for 60 minutes)

Not recommended according to the data sheet

Wet or greasy surfaces, natural and artificial stone (for example marble; on natural stone masonry do an adhesion test first), galvanised metal, copper and anodised metal, lead and lead paint, carbon/zinc (as listed in the data sheet), weathered or brittle PVC, and delicate or smooth interior surfaces.

For these jobs, pick another tape.

How to tape it right.

  1. 01

    Prepare

    Remove coarse dirt; the surface should be largely dry and free of grease. With morning dew, wipe the surface briefly and apply the tape straight away. On highly absorbent surfaces do an adhesion test first.

  2. 02

    Press on

    Work the tape into the texture with pressure and press the edge on firmly with a squeegee or spatula.

  3. 03

    Seal and paint

    On rough surfaces first paint a thin coat of the base colour along the tape edge. Then apply the paint generously, away from the tape.

  4. 04

    Remove

    Remove the tape right after the last coat while it is wet, at about 45° and without jerking.

Questions about EDGE RED

What is EDGE RED made for?

For rough surfaces outdoors: exterior and textured render, concrete and masonry, timber facades, windows and doors outdoors, balconies and terraces. According to the data sheet also for automotive and industrial coating.

Can I use EDGE RED indoors too?

According to the data sheet, EDGE RED was developed primarily for outdoor use. For delicate surfaces indoors use EDGE VIOLET, for smooth interior surfaces EDGE GOLD.

Does EDGE RED hold on rough render and concrete?

That is what it is made for: the fibre-reinforced washi tape (110 µm total thickness) has 2.0 N/cm adhesion to steel. Work it into the texture with pressure and first paint a thin coat of the base colour along the edge.

How long can EDGE RED stay on?

Remove BRAUJE right after the last coat, while the paint is still wet – that gives the cleanest edge. The UV resistance (EDGE GOLD and EDGE RED up to 16 weeks outdoors, EDGE VIOLET indoor only) tells you how long the tape withstands sunlight – not how long it can still be removed cleanly afterwards.

For comparison: manufacturers of washi masking tapes state periods from a few days to several weeks for clean removal, depending on the tape and use (manufacturers’ information, as of October 2026, without guarantee). There is no BRAUJE measurement for this yet.

Can the surface be damp?

Slightly damp yes, wet no. With morning dew, wipe the surface briefly and apply the tape straight away.

How much heat can EDGE RED take?

Up to approx. 150 °C for 60 minutes according to the data sheet (test method ATST008). That makes it suitable for multi-layer coating at high temperatures as well.

Which width should I use for what?

According to the product data sheet: 30 mm for colour lines on facades and exterior render, 38 mm for plinths, facade profiles, balcony edges and exposed concrete, 50 mm for facade areas, industrial coating, automotive, roofs and dormers. Every roll is 50 m long.

What does EDGE RED not stick to?

Not recommended according to the data sheet: wet or greasy surfaces, natural and artificial stone, galvanised metal, copper and anodised metal, lead and lead paint, weathered PVC, and delicate or smooth interior surfaces. On natural stone masonry do an adhesion test first.

Is EDGE RED a plastering tape?

According to the data sheet, EDGE RED is made for colour lines when painting and coating. The data sheet does not list plastering as a use.

How should I store EDGE RED?

At 18 to 21 °C, at no more than 65 % relative humidity, out of direct sunlight and with no weight on the rolls. In its original packaging EDGE RED keeps for up to 12 months according to the data sheet.
