Lineco Foil Sealing Tape

Retired from the grind
Largely through the recommendations of you guys on TG, I have recently begun to use the Lineco 1-1/4” Foil Sealing Tape in an attempt to line the rabbets of frames for stretched canvas.

I am finding it difficult, though, to apply the tape to both the lip and the depth of the rabbet with a single strip of the stuff. Instead, I have found I need to cut a 1/8” (or so) strip to apply under the lip, then separately apply the remainder to the depth of the rabbet.

This two step method sometimes results in a slight gap between the horizontal and vertical surfaces so that a small portion of the wood is still exposed.

Can anyone suggest a method of (or a trick to) applying a single strip of tape to cover both the rabbet lip and rabbet depth at the same time?
Well Bill, this usually works for me but there's no guarantee it'll do the trick for anyone else. I take a burnishing bone and lay the tape along the rabbet in such a manner that, when I drag the bone down the junction between the rabbet and the inner part of the frame opening it creases the tape just right on both sides. Of course it takes some practice and sort of "the touch" to get it right every time. And I sometimes have to pull away and give it another go but it does a quick and nice job once you get the feel of doing it.

Sometimes I place my other thumb on the rabbet to sort of steady the tape and keep it pinned down as I work my way along the opening with the burnishing bone. It is much harder to explain than to do.

Fold and crease the tape lengthwise as you apply it, so that the fold fits neatly where the surfaces join.

Taping the rabbet before joining the frame corners avoids the problem of dealing with the inside-mitered corners.

It's OK to have a bit of tape showing beyond the lip of the frame, as you apply it. Cut off the excess with a razor blade.
I "fit" it before I peel the back off. Lay it in and position it with the backing still on, crease it with your fingernail, then peel and lay it in, and usually it will remember where you creased.
Never thought about taping before joining....what a concept! Thanks Jim!
Interesting what we learn from each other. I never thought of applying tape before joining either. Great idea.

I used Val's procedure for years....until just last week when I felt it was just not going as smoothly as I'd like. SO.......I pealed the backing off the first third of the strip, placed the first part of the edge where I wanted it and continued just like Framerguy said, using the burnishing tool (dealing in thirds or fourths keeps the tape from sticking to everything in site - including my arm). It felt a little akward at first, but got the hang of it. I might add, that with either procedure, I first cut a small piece (1 1/2") - same size as depth of frame - fold it in half, tear off the backing and 'install' it into a corner - repeat x3! THEN I put in the tape on each side, covering those four pieces. That way the corner is sealed.

using a straight edge, I score the backing paper at the 1/4" from one edge.

I then fold the tape over itself to crease along that score. This usually breaks the score and leaves me with a 1/4" wide strip of backing paper, and a 1" wide. I peel the 1/4" wide about 3-5"; using a Swipe and Wipe, I stuff the crease into the pit of the rabbit. [unjoined chops].

Then I continue to pull the paper away as I lay the 1/4" along the inner lip. Once that is done, I pull the paper from the 1" and smooth it down. Trim miter edges with a razor blade and join.

Only if I'm feeling VERY Museumy, do I add a tiny piece in the corners. :D
I didn't know it was necessary to put the tape over the rabbet edge. I thought since the glass covers that, and glass is a barrier, that would be OK.

What I usually do though is put the tape around the glass/mat package. I just read in one of the magazines that doing it that way not only seals it from the wood but also from any pollution (or dusties) getting in from the edge.
While pondering the problem last night (over a bowl of Ben and Jerry’s Cookies and Cream), I had a “Eureka” moment – or, so I thought.

I thought of lightly scoring the foil side of the tape and folding it over before removing the release paper.

But, Baer’s idea of scoring the backing makes a whole lot more sense!

Not only (with a light enough touch) are you less likely to cut through the actual foil tape, but you will be left with a little edge of release paper with which to grab and peel – which I had trouble finding. Now it works like a charm.


Sorry, I did not describe my original problem well. I was referring to oils and acrylics on canvas that were <u>not</u> to be glazed. In your scenario with glass, I don’t believe that it would be necessary to seal the rabbet lip either.

Thanks everybody.
I like your technique Baer! Gonna practice today. But I really like your new word for entry into "Baer's Dictionary" = 'museumy'!

Does that ever say it all! "OK.....I have Mrs. Whole Wheat here to frame a s/n print that she absolutely adores and wants to pass on to her children. Just how 'museumy' shall we go on this one?" GREAT word!

Now I have a Webster's AND Baer Dictionary at my side.......it's come to that!
I cut the tape to the length desired, take the release paper off, and then put it back on so that 1/4 inch of the stickiness is exposed. That is then applied to the lip. The release paper is then pulled off for good as the tape is pressed into the rabbet depth.
Love your name!

Did you go on the march? :D ;)

Sherry! Please, I'm begging you DO NOT perpetuate that word.

It just slipped out from watching an old re-run of This Old House... where Steve used the term "that old timey look". Which is a superlative for "romanticized antiquated slock".

Kind of like certain things done by a certain TK.
Hey y'all show a little respect for this lass!!

Heck, who knows, we may be related!

I have taken the liberty of pulling my favorite photo from my profile so you know what I'm talking about.


OK, so some of that manly chest went South, but the rest of me did too so don't be making any smart comments!!

That's a very nice photo Framerguy. So often our kind are stereotyped as just party-animals or Mafioso. Which we are. But there’s another, more sensitive side, and your photographer has captured that.
Yeah, I remember those old days down at the swimmin' hole, doin' the back stroke in nuthin' but our black & whites, just partying the afternoon away, those were the fun days alright.

I failed my Mafia test when I was younger when they found out I couldn't hit anything with a Tommy gun!!

And I took all the criticisms with a smile too. Being mistaken for a nun when you're in touch with your innerself is a real bummer, I have to say. I fixed that when I grew a beard. That threw most of the flock into a tizzy!

Hang in there, PWSG (or should I use your nom de plume, ........Lisa??)

Deac, I used to, but then one day without coffee, I sealed the wrong stick with the last of the tape....

well you get the picture...

That was one of the nicest gold leafed rabbits I ever did....
