Help Linco See Thru strips

[JBergelin]

Could someone suggest why Linco See Thru Strips would fail -

We framed heavy water color paper with strips three per side .... the bottom ones failed and the art slipped down - the other side pieces appear to be strong.

This is for a high end French restaurant - in the bar area - I don't believe that there is heat or humidity - no hot fat or grease in the air.

I am concerned because we have 9 other pieces thru the areas and if the others are going to fail I want to get them first.... the mounting board is not marked in any way where the strips dropped ..... they just dropped down ..... it would be good to know why.

We are adding hinges to the top of this piece.

thanks for the help

You did not indicate the size nor paper weight.

If it is a full sheet of WC paper in the 225 - 300 pound range, you did not use enough strips. I would have preferred to use a full frame width piece of 4 ply or 8 ply as a bottom support for the size and weight I assume you have.

Doing the same on the other 3 sides and you have a "sling mat" mounting.

Pressure-sensitive adhesives will ultimately give up to the pressure of gravity, especially if the item is heavy enough. The hinges added to the sheets should address that issue.

The last shop I worked in always reinforced these strips. I would lightly sand the plastic. Then I would use gummed linen tape over top. By sanding the surface it gives tooth for the linen tape to bond to. We alays did this and found it to be very smart. Keep a little piece of course sand paper near your table when using these strips.

Belt and suspenders, ALWAYS belt and suspenders.

Turner, I can't tell you how many (not that old) pieces of gummed linen tape that doesn't peel off, it just falls off. The gum desiccates.

This post really interests me. I always use these strips because I don't have real experience with true conservation hinging, i.e japanese paper and rice or wheat starch. While working for a retail shop that didn't practice very safe mounting methods, I attended a PPFA conservation class (over 6 years ago). I never was able to use what I learned at the store. When I started framing at home, I didn't have the confidence to use the paste. Do you make your own? or buy the premade stuff. I plan to order some of vivian's videos, including the conservation one. Honestly, I am a bit intimidated by sticking a hinge directly to a piece of expensive or old art. I know it's the "right way," I'm just saying it scares me because I have never used it on real art...I have always used the strips because they seemed safest due to my lack of experience. After reading this, I realize I really need to learn more about conservation mounting techniques. I'm not afraid I've damaged anything, BUT I am concerned someday they might fail :-(

hmm...I just read my post and don't want it misunderstood. hehe...I wasn't implying that "I" didn't use safe mounting techniques (I just witnessed others doing some stuff that common sense told me wasn't good...and so...i decided to take a class. I like to do things "right."

I have an artist that uses 300 lb WC paper. I do what Turner does and reinforce with heavy duty linen tape. At first I used two strips per side. That failed. Then I used corner pockets in addition to the strip. Some of those failed also. I have since reinforced with heavy duty linen tape and have had no problem.

When I've used them, I make sure that the whole area out around them is built up to the same height as the strips. Not only does this physically support the strips, but it prevents wierd pressure problems from developing. If you don't build out like that, the pressure from the flexpoints or fletcher points or whatever on the back will eventually make the mat sag or let such plastic strips slip down.
