another airbubble problem: frosted effect on glass

Just been searching this site for problems with air bubbles.
I did a window very recently with lettering a bit bigger than I have done previously. It was with Avery Frosted glass effect.
Application went fine (I applied dry) but I noticed now that there are a lot of little air bubbles trapped. I tried to rub them out: pierced a little hole and used the squeegy. But I can't get rid of them.
You only notice the bubbles from the outside (and close-up). And although the customer is happy with it... I am not and would like to redo it.
How do I prevent this happening? Should I apply wet? :o
Thanks

Noooooooooo


what type of shop is it, I think moisture can cause this sometimes if I remember correctly.

It's a food place ... lovely and warm in there from all the fridges and freezers...... How would that work with moisture? It was a cold, wet and damp day when I applied it.... Does that have any effect?
I cleaned the window (methylated spirits) and dried it nicely before hand?!?!?!

Hasn't it disappeared over a few days?
Glass is always cold, even on a warm day so it might take a while to settle down.
Check your squeegee for nicks or wear.
Sometimes squeegeeing (is that a word?) too vigorously can cause it.
Pricking etch can make it show up even more unless it is sparkle etch.

I wouldn't apply wet as Warren says, unless there's no application tape to remove, then you would be OK.

Are the bubbles all over or is there a pattern to them ie horizontal, vertical or patchy?

Are you using a lint free cloth to clean the glass?

The trouble with meths is that it does leave a residue which you should clean off with a clean cloth.

Ive found that wiping the glass clean is not enough. i also use a scraper. you will be surprised how many particles are still on the glass. it will look the same as air.

I did the work just before christmas, and I had hoped they would disappear.... It is the frosted sparkly effect, so pricking it hasn't made it worse.
The bubbles are all over... not in a particular pattern.
I used a clean lintfree cloth to clean the window after I had rubbed the meths off with a tissue.............

Chris has a good point, I also use a window scraper. But, I think even if you didn't you probably would have felt any particles that may have been there and cleaned them off.

Can you post a pic?

eeeh... sorry no pictures... I did not have my camera on me (and I don't think the camera on the phone would have picked up on the detail.....)

Angelique,

I applied some Oracal etch dry on my shop window - there were quite a few bubbles on it - too many to count - again popped a few but not all. It took a while - maybe 2 or three months and maybe only when there were big temperature differences - but there are none now.

If they are happy with it just leave it I would say - hopefully will just go.

TBH if I did my window again I would do it wet. Have done plenty since wet with no problem.

Last year or so I did a whole window with some foil I bought a hardware shop. I applied that wet and it took a couple of months to settle , but now there is no bubble in sight...
So maybe I should be patient......
I do feel that the window was clean (I remember the first one I did I used a scraper first.... but it was so clean that I did not bother using it on the second window...
I know the customer is happy with it and that I could leave it,... it's just that I am not... and I don't want potential customers looking at it...thinking it is really bad work..... :o

Nearly all my etched windows are done wet, no bubbles at all, ever.

Scrape thoroughly with a stanley blade, or suchlike.
Wipe clean with app fluid or alcohol cleaner, then scrape again, then clean again till your cloth or tissue etc is totally clean.
I fit dry, but whatever works for you.

I always apply window etch wet and have never had bubble problems when done that way. I did 24 large areas recently and not a problem, except for the one or two I did dry :oops: So I ripped them off and redid them wet with no further problems. They dry nice and tight with no bubbles. I always use rapidtac as this makes the application tape easy to remove. After squeegeing the graphics flat and removing as much of the rapidtac as possible I then spray the application tape (paper type) with Rapidtac and leave it for a few minutes to soak in and it then will peel off really easily.

I do full sheets wet I must admit, simply for speed... no app tape, just lick and stick. Lettering I always do dry.

I think you just need to wait. Cold surfaces will not breath as much as a hot surfaces, so I'd not sweat at all. If the customer is happy, I'd leave it at that :wink:

Thanks for all hints/tips/advice.
I will leave it and hope that it will improve soon (but with the terrible weather at the moment I don't see that happening).
I suppose next time I will try and apply wet......

Thanks again
