Case Study: Real Business, Real Results

"The Pie Tin," a bustling bakery in York, relied on an outdoor A-board to attract tourists and  locals. Their previous chalk pens would run in the frequent drizzle, leaving their 'Pie of the Day' a smudged, unappealing mess by lunchtime.

"We needed something that would stand up to the British weather and  still look sharp and  professional. These Securit pens are brilliant – the line is so bold and  bright, and  they genuinely don't run. It’s made a huge difference to our kerb appeal."

David Carter – Owner, The Pie Tin

The bakery reports their specials board is now legible from across the street, helping to increase walk-in custom for their daily featured pies by over 20%.

Installation and  Maintenance Guide

Setting It Up

  • Before first use, shake the pen vigorously for about 15 seconds with the cap on.
  • On a spare, non-porous surface, gently press the tip up and  down to prime it and  start the ink flow.
  • Write your message and  allow it to dry completely for a smudge-proof, rain-resistant finish.
  • Always replace the cap tightly after use to prevent the nib from drying out.

Keeping It Going

  • To clean your board, use a damp cloth with Securit chalkboard cleaner (Y994) for the best results.
  • Avoid using abrasive pads or scourers which can permanently damage your chalkboard surface.
  • Store your pens horizontally to ensure even ink distribution and  a long life.

Buying Guide: Choosing the Right Chalk Marker

Not sure which marker is right for your board? Here’s a quick rundown of what to look for.

Tip Size Matters

A 15mm tip like this one is perfect for big, bold headlines. For finer details, like prices or ingredients, look for a 3mm or 6mm tip.

Colour and  Contrast

White is the classic choice for traditional blackboards, offering maximum readability. Using a commercial liquid chalk pen in a different colour is great for highlighting key info.

Indoor vs. Outdoor Use

If your sign lives outside, a rain-resistant formula is a must-have to avoid messy, washed-out messages after a short shower.

Ease of Cleaning

Liquid chalk is much cleaner than traditional chalk sticks. Check if a specific cleaning fluid is recommended to avoid 'ghosting' (faint marks left behind).

Surface Compatibility

These pens are designed for non-porous surfaces like chalkboards, glass, and  metal. Always test on a small, inconspicuous area first if you're unsure.

Frequently Asked Questions

Q: Can I use this pen on a painted wall or wooden board?

A: We don't recommend it. These pens are designed for non-porous surfaces like proper chalkboards, glass, or metal. Using it on a porous surface like painted plaster or untreated wood may make it permanent.

Q: How do I get the ink flowing for the first time?

A: It's simple. Just shake the pen well with the cap on, then pump the nib on a spare, hard surface until the ink fully saturates the tip. You'll see the white ink start to flow down.

Q: Is the white chalk marker 15mm completely waterproof?

A: It's rain-resistant, not fully waterproof. It will withstand typical British showers and  morning mist without running, but it's not designed for a prolonged torrential downpour or being submerged in water.

Q: Will it leave a faint 'ghost' mark on my board after cleaning?

A: When used with the recommended Securit cleaner on a quality, non-porous board, it should wipe away completely without leaving any ghosting.

Q: How thick is the line from this 15mm tip?

A: The wide, oblong tip allows you to create thick, blocky lines up to 15mm wide, which is why it's so good for headings and  grabbing attention from a distance.

Q: Is the ink safe to use in a café or restaurant environment?

A: Absolutely. The liquid chalk is non-toxic and  odourless once dry, making it perfectly safe for use in any food service setting.

Q: How should I store the pen to make it last longer?

A: It's always best to store chalk markers horizontally. This prevents the tip from either drying out or becoming over-saturated with ink.

Q: What surfaces can I use this on?

A: This liquid chalk marker for boards works brilliantly on chalkboards, whiteboards, glass, mirrors, metal, and  most other non-porous surfaces.

Why 'Rain Resistant' Makes All the Difference

Ever written the perfect message on your A-board, only for a classic British shower to turn it into a streaky, illegible mess? That's where 'rain-resistant' technology comes in. It doesn't mean the ink is permanent – far from it. Think of it like a good quality raincoat for your words. The formula is designed to repel light rain, drizzle, and  morning dew, ensuring your message stays crisp and  professional throughout the day. It won't wash away with the first drops, protecting your hard work. But, when you're ready to change your specials, it comes off easily with the right cleaner, giving you the best of both worlds: durability against the elements and  the flexibility to update your signs whenever you need to.

Who Should Buy This?

  • Cafés and  Coffee Shops: Perfect for writing daily specials, coffee blends, and  tempting cake offers on your main blackboard.
  • Pubs and  Bars: A must-have for listing guest ales, quiz night announcements, and  cocktail menus that need to be seen.
  • Restaurants and  Bistros: Use this restaurant chalk marker 15mm to create eye-catching menu boards for starters, mains, and  desserts.
  • Retailers and  Farm Shops: Ideal for bold pricing, special promotions, and  welcome messages on A-boards and  shop windows.
