Hello All,

I recently purchased, from two different sources, Chooch large and medium flexible cut stone walls. These were both new in original packaging.

Apparently Chooch has recognized the adhesive issue and is now shipping their flexible products with the adhesive backing as a user applied option, not factory installed.

Both came with the adhesive on a separate sheet.

Given the unevenness of the back of the flexible products I had doubts about this, basically large sheet of transfer tape, would hold.

I used contact cement to fasten the felxible sheets to porous wood frames. 

Following the instructions of the contact cement, I coated both surfaces to be joined with the adhesive. Allowed to dry until just tacky then pressed the two together.

Using spring clamps and strips of Luan, let them cure for 24-hours.

So far the bonds are holding, even around the curved sections.

Hope this helps.

On my test layout segment I used a good amount of yellow carpenter's wood glue to hold the chooch self-adhesive wall section in place. It has been holding for about 6 months now with no problem.

Over the past year or so my Chooch flexible walls have been slowly pulling away from the smooth side of the tempered hardboard; shame on me for relying upon their self-stick adhesive during installation in 2014.  Sure hope I can make a judicious save considering the delicate location.

Good luck,  Peter

Again, I will repeat. Drill pilot holes and tap in Atlas track nails. That will hold the loose material and the nail heads won't be obvious.

Hello All,

richhotrain
Drill pilot holes and tap in Atlas track nails. That will hold the loose material and the nail heads won't be obvious.

I recently had the opportunity to tour a working mine that produces Rhodochrosite, which is the Colorado state mineral.

On the rock faces of the mine there were rods and bolts holding some of the unstable rock.

Using track spikes or nails would not be un-prototypical to hold unstable masonry.

Hope this helps.

Maybe overkill and a bit obtrusive, but made the save with Evergreen styrene angle and Micro Engineering track spikes, only casualty a #24 drill bit.

Regards,  Peter

Thanks Rich, it was your post suggesting pilot holes and track nails that got my wheels turning.  Regards,  Peter
