Fair Shares for Both Tongues: Briefing a Bilingual Sandblasted Sign

Bilingual signage has a habit of looking like one language arrived first and the other was squeezed in afterwards. You see it on high streets: crisp English lettering with a Welsh line underneath that has been shrunk, cramped or blasted a fraction too shallow. The words may be correct, but the sign is telling customers something else — that one language matters more than the other. Sandblasting makes that message permanent.

This isn’t a lecture on language policy. It’s a practical guide for businesses in Wales, the Scottish Highlands and islands, Cornwall, and the multilingual parts of British cities. Whether you’re adding Welsh under English, Gaelic beside English, Cornish to a coastal shopfront or Urdu alongside English in a city-centre window, the craft question is the same: how do you blast two languages so they feel like one sign?

Decide what ‘equal’ means before artwork starts

Equal treatment doesn’t always mean identical letter heights. Welsh is often longer than English, Gaelic carries accents that need breathing room, and Cornish may have a different rhythm on the page. If you force both languages into the same box, one will end up looking pinched.

What equal treatment does mean is equal intent. Before anyone touches a mask, agree whether the sign is genuinely bilingual in status, or whether one language is primary and the other is a translation. Both are valid, but they produce different layouts. A shop in Eryri might want Welsh first and larger, with English clearly present but secondary. A Highland hotel may want Gaelic and English to carry the same visual weight. A city-centre pharmacy may need English plus two community languages, each with its own script and spacing needs.

Write that decision down. ‘Make them equal’ is not a brief. ‘Both languages at the same cap height, same blast depth, same paint fill, with Welsh on the upper line’ is a brief.

Line length is the quiet troublemaker

The most common bilingual sign failure isn’t bad translation. It’s bad fitting. One language runs longer, so the designer shrinks it, tightens the tracking or drops the letter height by a millimetre or two. On paper it looks fine. On a sandblasted panel, those small compromises show up as a second-class line.

Sort line length out at layout stage. Reflow the text. Widen the panel. Stack the languages differently. Use a two-column arrangement if the words are short enough. Break the longer language across two lines, but do it where a native reader would expect the break, not wherever the software runs out of room. Avoid squeezing the type. Sandblast lettering has no anti-aliasing to hide behind — what you draw is what gets cut.

If one language still needs more space, give it more space. A taller panel or a wider fascia is cheaper than a sign that quietly disrespects half its audience.

Same depth, same finish, same care

Depth is where bilingual signs often betray themselves. A blaster might go deeper on the larger language because it needs more shadow, then go shallow on the smaller one to avoid blowouts. The result reads unevenly in low light and looks like two jobs on one board.

Specify one blast depth for both languages, unless there’s a deliberate design reason otherwise. For most exterior shopfront work that means a consistent recess — often around 1.5 mm to 2 mm depending on material and letter size — agreed before the mask is cut. If the second language uses finer strokes, the blaster may need a different resist or a smaller nozzle, but the finished depth should still match.

Finishing matters too. If one language is paint-filled and the other is left raw, you’ve created a hierarchy nobody asked for. Same paint system, same contrast, same weather protection. Accents and diacritics need particular attention: they are small, they sit high or low, and they can disappear if the mask is cut too tightly. Check them at full size, not on a phone screen.

Lettering styles should be cousins, not strangers

You don’t need the same typeface for both languages, especially when scripts differ. You do need a family resemblance. A decorative script for one language and a plain sans for the other will look like two separate signs. Choose fonts that share proportions, stroke weight and mood, then adjust optical size so both languages appear equal.

For Welsh and English, watch out for accents such as the circumflex and the acute. For Gaelic, grave accents need clearance above the letter. For Cornish, check apostrophes and any diacritics in place names. For Arabic, Urdu or Bengali, don’t simply drop the text into a Latin typeface and hope. Different scripts have different x-heights, stroke contrast and reading directions. A designer who knows the script should set it, and a native reader should proof it before the mask goes anywhere near the blaster.

The brief that keeps the blaster honest

A good blasting brief is mostly about removing ambiguity. Supply vector artwork with both languages outlined, on separate named layers. Give the panel size, material, required depth, resist type and paint specification. Mark the reading order clearly. State which language sits on which line, and include a full-size paper proof or a plotted template for checking spacing.

Ask for a test blast on an offcut if the material is new or the lettering is fine. Confirm how accents will be masked and whether the blaster is expected to adjust spacing. Usually they shouldn’t be — that’s a design decision, not a machine setting. If the sign is curved or irregular, give a baseline drawing, not just a flat artwork file.

Above all, get a bilingual proofreader to sign off the final artwork. Not a translation app. Not the person who Happens to speak a bit of the language. Someone who reads it naturally. The blaster can reproduce a mistake beautifully, but they can’t save you from it.

One sign, two voices, no favourites

A bilingual sandblasted sign should feel like one object, not a translation with a host language attached. That means equal craft, not necessarily identical geometry. Give both languages the same depth, the same finish and a layout that lets them breathe. Brief the blaster properly, proof the accents, and don’t let anyone ‘fix’ the spacing at the last minute.

Get it right and the sign says something before a customer reads a word: both languages belong here. Get it wrong and the grit will keep reminding everyone which one was the afterthought.
