[Jill Marie Welsh]

Anchor brand stencil material is what I’ve used.

Hi Matthew

A guy local to me does a lot of work on glass and sandblasts
it himself using cut vinyl masks.

As he only has an old tiny cutter I have often cut larger patterns for him
which he has stuck on and blasted.

He always said any vinyl will do so I have used whatever was to hand.

I suggest you do a test piece for your customer to try

Hope that helps

Chris

Hexis do a sand blast material which is very tough
I have had problems with "ordinary vinyl" and "paint mask"
But it depends on the power of the sandblaster.

i use any vinyl to blast on glass, though it gets brittle after blasting and therefore comes off in small pieces, not a problem on mirrors as i blast from the back and leave mask on

[Andrew Bennett]

I do sandblasting and use vinyl most of the time.
It doesn’t get brittle when I use it. However it does depend on if you are frosting or carving the glass.
I would love to use Avery 4mil paint mask but have not really looked for a supplier for it.

I too leave the vinyl on the back of mirrors, taking it off is a pain.

I have found though that for some unknown reason, silver and gold vinyl is a better resist. Maybe the glue is thicker or something.

Good luck.

grafityp do a good thick blast material

I recently bought some of the medium duty sandblasting vinyl off dorotape, It looks great stuff and cuts well but I haven’t been able to get it off the backing sheet in tact as its way more stickier than application paper, would love to hear other peoples experiences of using this, and any advice of how they have overcome this problem

[Dermot Howard]

I’ve used regular vinyl and more recently used sign mask and they both work fine. just dont use a massive amount of pressure.

[Martin Pearson]

If the guy is looking for a mask that he can use over and over again then the centres of letters are always going to cause a problem o matter what material you use. If he is using a small desktop box then the pressure in these is generally not to high on the gun so a normal vinyl should be OK as others have said.

Jason what tac application tape are you using, might be worth trying to get a sample from one of the suppliers of a high tac tape and try that, or even ask Hexis what they recommend for the material you bought from them

[dannygriffin]

yeah the backing can be a real nightmare to get off. But if it is that sticky, you know it will not lift while you sandblast it.

If the tape has a chalky powder you must remove this with a tac cloth. we then use sellotape. yeah sellotape. you can still see the cut images and you get the hang of peeling. you must peel 180 degrees from the sticky side and stick down as you go. if some of the stencil starts to remain with the backer you work backwards and if you have to use your hands or a scalpul to get it off the backer.
It can be a tricky job, tram line circles are the worst.

there is no easy way, you just need to suss it out.

having someone show you is the best bet.

find a monomental mason who might show you them sticking down the inscription ( no an easy thin to get info out of a mason )

[dannygriffin]

Yeah

it depends on how deep you want to blast.

I have a small hand held ‘frosting’ blast pot and regular vinyl is ok.
But if you want to blast 5-mm + in granite you need anchor.

very sticky and sellotape works as an application material.

Just had a request for a big business next door who manufacture windows for boats, and are about to start doing their own sandblasting. The remit is for a suitable vinyl which doesn’t leave any residue behind when removed, and is suitable for use on reflective coated glass.

I will phone Grafityp etc tomorrow, but wondered if there is anyone experienced with this type of request?

Thanks
Lorraine
