It's my understanding that strainer bars should be sealed with a polyurethane to keep acid from damaging canvas or giclee materals. Is an acceptable alternative covering the side and lip of the strainer with an archival frame sealing tape? Such as Lineco's?

I did a quick search but couldn't find my answer.

MUCHO THANKS!!
 
The Lineco is a true barrier.... and I have never heard about polyurethane... which bleeds acid for decades....

So you can just use raw like almost everyone else and have those nightmares that disrupt your Free Cell gaming..
If you really want to get crazy.. three coats of 3lb cut shellac....

But then Jim or Nona can come on a tell us how I have no proof that shellac works either...so, there's always raw.....

hope that helps... you can slap me around in Vegas. :D
 
Wouldn't artist's gesso (like Liquitex as opposed to gilder's gesso) act as a barrier on a strainer??? Krylon even makes what they call "Spray Gesso" but it seems sucpiciously a lot like white primer if y'all ask me.

I use Liquitex gesso on those cheap balsa wood spacers from United and then acrylic paint over that if need be. I mean, I figure that acrylic paint (and ground) is good enuf for the ARTWORK......???
 
No plastic is a true vapor barrier, as a metal foil is, but most should reduce emissions from
the side grain wood of a strainer. The most important thing to remember is never use wood with
any knot holes and do add a backing board, to
keep damage from the back and air pollution from
reaching the canvas.
