Do you use it (be honest)? And if so, what brand? I'll be ordering some in Atlanta and need to know what to use. Thanks for the help.
 
I'm right there with FramngFool......

LINECO - use it whenever the customer wants conservation framing done! That's about 75% of them.

Don't forget to charge them for it!!! ;)
 
lineco and I use it on All fillets and frames within two inches of the art work. (I know Facts says 1")
 
I don’t use tape. It’s mainly a matter of economics and æsthetics.

Some time ago I calculated/estimated that it cost me 12-15¢ to back a 16 x 20 frame with black Kraft paper and white glue.

Using Lineco, it would cost me about 75¢ for the same frame, I think.

I like the look of paper backing and the taste of the glue.
 
I think we're getting frame sealing and rabbet sealing mixed up.

I'll sometimes use the Lineco Frame Sealing Tape to seal the back if a paper dust seal is impractical for some reason. Maybe this is the same tape some of you are using to seal rabbets.

I have never taped a rabbet in my life.* If I feel the need to isolate the contents of the frame from the frame itself, I'll seal the glass, mat and backing together and drop the whole thing into the frame.

*Okay - maybe once or twice.
 
Ron,

What about pieces on canvas that come into direct contact with the frame? Do you use lacquer, or is there some voodoo i don't know about?
 
To seal it you must use an non-permeable barrier. Only glass and metal qualify and the Lineco tape has the requisite aluminum layer.
Lining the rabbet and subsequently perforating the tape with points in counter-intuitive. There are also arguments against taping the mount/mat/glass package as there may be issues with variable contraction and expansion rates of the included materials.
I have been experimenting with attaching a layer of metalized polyester to the back of the mount and then taping the mount to the glass with the Lineco product. It is a derivative of the sealed frame package that Hugh Phibbs developed and teaches in his classes. I don't know if it can be called a sealed package, but it does minimize the area available for any environmental changes in the frame package.

Sealing the rabbet of a frame for an oil painting is as much to keep the still plastic pigments from adhering to the lip as it is to prevent outgassing of acids. The acidic outgassing is only a concern when the material emmiting the acids are contained within the sealed frame package. There are products made specifically for the lining of the rabbet for oil paintings (Volara from Lineco).
 
I think we're getting frame sealing and rabbet sealing mixed up.
Oh, okay, I get it now! The answer is still, "no", I do not seal the rabbet.

If I am reading F.A.C.T.S. correctly, the rabbet is excluded from needing sealing for oils/acrylics on canvas.

And, although one should not have paper borne art within 1” of the rabbet of a wood frame unless it is separated by metal or glass, I am not sure that a “foil tape” qualifies as a metal. :confused:

… Oh, crud, here we go again!
 
A leaf or very thin sheet of metal; as, brass foil; tin foil; gold foil.
Source: Websters Dictionary

Definition: Metal in any form less than 0.006 in. in thickness.
Source: Metalinfo.com

And I found this one on WordNet Dictionary:
foil - anything that serves by contrast to call attention to another thing's good qualities; "pretty girls like plain friends as foils"
Synonyms: enhancer
Now thats Funny!

Yes, Lineco paper-backed foil tape qualifies as a metal, and satisfies the FACTS requirement for a gas-impermeable barrier.

Incidentally, the 1" distance applies to all planes. That means that if a fillet is used, it must be at least 1" from any part of the art paper; which generally means 1" above the paper. The gas-impermeable barrier helps, but some of the fillet's wood surfaces may still be exposed through its finish, so it's still an exception to the guideline. And that's OK.

Now you see why FACTS encourages informed 'exceptions' to the guideline, according to each project. FACTS doesn't say the fillet shouldn't be used, but that we should understand the possible hazard it represents in terms of preservation.
 
Ok Jim, I understand that Don Pierce hates fillets and all that is fine. But the industry now exceeds 1,000 fillet that are "HOT" sellers.

I have crawled all over the FACTS site and I have yet to figure out what FACTS considers Ph "neutral" (6.5-7.5 or 7 only) and where they show the results of tests as to ph levels of things like Silk, bass wood fillets, Alphamatboard etc.... and if there are findings, who did the tests? Independent lab? University students? Museum?

I've said it before, and I'll say it again. Order the one from Gaylord. They specialize in conservation products like lineco and it actually sticks to the wood!
