blackboard sign

[Robert Lambie]

i haven’t heard of a chalk pen before… i cant imagine how that would work as the liquid/ink has to be wet and chalk is dry. 😕
I’m guessing I’m missing the obvious?

I’ve seen the day-glow pens, ultraviolet and numerous others type ones but chalk?

sorry my reply is of no help… just puzzled me a little

[Peter Normington]

Not sure if this is the way you want to go but We have used anti graphiti laminate for similar, Works great with the pens, and it wipes off easily

My clients use Mactac MACal 9800pro Black Matt 9888-00 with water based chalk pens or blackboard markers by illumigraph not the spirit based ones, with either a white or black foamex board 5-10mm.

hope this helps

I used to use chalk pens in the pub. they are not good on real backboards either, but more suited to glass. How about using glass with a flood coat of black vinyl applied to the reverse, giving the impression of a black surface, but actually writing straight onto glass.

I have a similar question – is there a vinyl that can be used to create a dry wipe surface? – I want to make up a dri wipe board that will accept magnets as well so I will need to cover some metal sheeting with a white dri wipe surface.

I hope I’m not hi-hjacking your thread Jon – but this is a similar question 😀

[Lorraine Clinch]

Jon, I’m really happy that you brought this ? up, as I have suggested blackboard vinyl for a client, who is using chalk pens. I know from experience that chalk pens leave a shadow on blackboard paint, thought vinyl would be OK. I shall suggest dry-wipe vinyl instead.

Phill-Metamark do a dry-wipe, works well with marker pens (non-permanent).

[Jim McManus]

Phill,

I also had a similar situation in the pub with this. The darts team used to use chalk for their scoreboard but the dust went everywhere and was a nightmare to keep clean, so I covered the scoreboard with ordinary white 651 and gave them a box of Nobo markers and a box of Nobo wipes. This worked out fine. By the end of the season, the vinyl looked a bit grubby, but it had a lot of use ( as the teams scores went down by an average of 17 per three darts). The good thing is it cost virtually nothing and was easily replaced.

Hope this is of some use to you.

I think Robert Horne Group do an actual chalk board material 3mm thick!!!

Hexis do both Dry Wipe film and Blackboard Vinyl and will send you a sample if you need one

I had the same problem. Did blackboard vinyl for a customer. It is expensive, hard to cut, with a rough texture. He used pens on it and it has left a mark that he can’t get off.

There are chalk pens and there are chalk pens… Some leave worse ghosting than others.

The Kuretake ‘Illumigraph’ pens usually come off most chalkboard surfaces (ink/paint/HPL/foamex/HIPS) with a bit of warm water and washing up liquid.
Pentel’s new ‘Wet Erase Chalk Marker’ pens tend to leave more ghosting.

A couple of solutions?

First thing to try is Mr Muscle window cleaner (green coloured). This works pretty well, but might not if the chalk has been on for a few days.

For more stubborn ghosting, use a non-scouring household cream cleaner (such as Cif). If this doesn’t work, then it’s time to scrap or re-paint the board.

The make that i’m familiar with is Zig, they do pens also make a cleaner, i’ve used this combo on hexis drywipe and chalkboard vinyl with no problems.

I’ve got a customer who made a special recipe for cleaning his boards, all i could get out of him was that it had Coca Cola in it!! I tell you what though, it was better than the zig stuff.
Imagine what Coca Cola must do to your insides.

That’s the Kuretake trading name for the Illumigraph

That’ll probably be the be the phosphoric acid. you can use drums of coke to clean rusted parts!
