Just took on a project to replace a couple of glass mats from the 40's. This is in a set of 18 framed pieces that 2 broke in shipping. I have no problem matching the colour of the paint to apply to the backside of the glass, but have a question as regards to wether the latex acrylic will adhere properly to the coating on the Tru-vue conservation clear that my customer prefers ( and I encouraged ). the originals ,of course, are on regular clear glass from the old days, but if there is no problem painting the glass mat on the coated side of the glass my customer would like me to do all 18 pieces in consv. glass. Has anyone done a glas mat on consv. clr and what should I expect if anything as opposed to glas mat on reg. clr. glass ? thanks for your input..Happy New Year.
 
wont get into your main "?" about paint adherence except to say call the glass guys & ASK em! I was thinking that to save you time/trouble(& cust some $$) you might just glass over the other pieces instead of taking apart/redo each mat? not sure how that would "look" but sure would save work, opinons anyone???
 
I would do some experimenting before saying yes or no to this job, painting mats on CC glass. The paint may "crawl" like a juicy watercolor marker (which I use if I lose track of which side is which) - and if the paint does indeed stick to the CC - then hit it with a blow drier or heat gun - scrape at it a bit - kinda test it to see if it stays put, doncha know.

I am guessing if anything would stick it would have to be enamel, like they used originally on glass matting. Or check in the airbrush department of your local independent art supply store - the Createx line of paint is formulated to stick to just about anything from hockey helmets to race cars. Hmmm...maybe you would have to "scuff" the area to be painted first??? Hmmmmm...

Keep us posted!!!

Edit: Ya know, what I wrote sounds like a royal PITA - I like Bill's idea of glassing over the old ones!!!
 
Bill...won't work due to depth of material already flushes to back of frame, plus won't look right..also $$ is not a problem ( got to make it when you can in this economy).

Framar...I do airbrushing a lot and your idea is fine except color match can be done only at my friendly paint store in acrylic latex an my auto paint supplier can also mix it with auto enamel ( the old style of enamel)... this is a computer match system that they use on color...not avail in Createx ( I use it a lot also )...willexperiment Monday with both types of paint and see whAT happens..will let you know.
 
What about using acrylic with UV protection, instead of glass? With acrylic, there is no coating, so you don't have to worry about it interfering with the adherence of the paint. And the shatter-resistance would protect against the harm that brought the job to your door in the first place.
 
Another thought - if you are an airbrush artist why do you need a paint store computer to mix a color for you??? Can't you do that yourself, especially since it sounds like you have a lot of paint?!?!

Paulie, paulie, Paulie...... you should always be thinking about getting back. . . um, er . . . getting IN the next order. :D

"Oh gee... it broke..... again." :thumbsup:

Oh, and about black on CC coating.... Krylon stuck just fine the last mat I did....
 
I would not put a second coating of glass over them. Your reduction of visible light transmission and amplification of any distortion in the glass would probably be noticeable.

Createx is an acrylic. Acrylic latex paint is an acrylic. If the glass is clean and free from any oil film there is no reason either one shouldn't stick well to the glass. You would get better coverage with Createx or another artist's acrylic since there are less binders used and the pigments are purer and more concentrated than house paint acrylic latex.

I just did a quick experiment with Winsor & Newton's acrylic and it adhered to the coated side of CC glass quite well. Of course it is scratchable so take caution not to abrase it after painting.
 
This was covered a bit some weeks ago here . . .

There may be some info there to help.

TV once advised me that they bake their coating on at about 400oC, so that's a good start.
I'd say you should trial and leave for a week or so to see what happens.

I'd try a couple of pieces . . . a plain mask and paint on one piece, then a mask and light rub with an ultra fine sandpaper (1500 - 2000 g) to help adhesion on the coating to be painted.

Maybe Edie did her job and has some results ???

I never thought of using a watercolor marker to check which side has the coating on CC glass. Interesting idea. I just scrape a razor blade about 1/16th of an inch from the edge, to feel which side is coated.

I am not at my computer, so I can't post photos of my completed project just yet... but stay tuned. I meant to revive my thread after the holidays.

I did not even try the mats on CC glass, I was just sure the orange peel texture would interfere somehow. BUT, it's good to hear from Maria that they can work... cool!

I did mine on UV plexi and they worked beautifully. I used flat black krylon spray paint and metal leaf as well. I'll post details when I post the photos.

Why the big concern with exact color match if you are replacing the entire set...they will match each other.
 
wpfay.....they have to match some other pieces that are different art and larger sizes that will not be replaced until later if ever..so color match is critical..same artists, same frames, same wall display etc.
 
OK...ended up using the auto enamel and applied it with my medium size auto touchup
gun (big airbrush) HVLP type....it looks so original and was pretty easy actually...had to be very careful cutting stencil on coated side of glass...now we'll see if it is still stuck on the glass after about a week before we call it a success.
