Wallpaper mural art project

I took a pre-pasted wall mural, stuck it to smooth marker type panelboard, and am going to put a frame around the individual panels. However, after applying the pre-pasted wallpaper and several days of dry-time; some edges, and one whole panel didn't stick. Not sure the best way forward...re-wet the edges and panel, and try again? Maybe trying to apply some wallpaper paste? Or maybe just glue the edges and paste the one panel? Any suggestions would be greatly appreciated.
thanks....J.

 

Maybe trying to apply some wallpaper paste? - Yes

 

I used to work with a paper hanger and he never trusted pre pasted paper - he always re pasted it before hanging it.

 

Havent done as much wallpapering as in the past and initially I also pasted pre-paste paper.

What minimal amounts of wallpaper we have done at current house most was pre-pasted and as long as you used the proper tray to fully wet the paper it worked fine, cut down the install time!

 

Please do NOT use what would be considered Pre-mixed regular wallpaper adhesive. It will ruin the print.

You can purchase CELLULOSE adhesive. This type of "mural" adhesive is usually not available at BigBox stores. Paint stores do carry it, usually. It comes in a dry, granulated form and is mixed with water. Following the direction. Mix a portion of the mix rather than the whole package IF you are concerned about simply repairing small loose portions of the of the mural panel. Just halve or quarter the package and the water to dissolve it.

As per the directions, once it is diluted, allow it to sit in a small covered container over night. You may apply it with a paint brush, tucking the paste in back of the wallpaper and then softly smoothing it out with a wrapped broad-knife and taking care not to overwork it. When doing this, take a soft cloth that is wet and rung out but not completely rung out, preferably a microfiber cloth (as it is very soft) and WET THE SURFACE lightly and allow the mural to soften up before working it. This is important.

BEWARE: Care MUST be taken NOT to rub over the printed surface where there are creased.
These murals are VERY fragile on the printed surface and the least bit of "over working" or applying too much pressure will cause the print to lift right off.

If you run into any issues, post again.

 

FYI, Mark, Cellulose paste is a "must use" adhesive for any mural unless it is a really heavy-duty printed-on-vinyl mural

All other "paper" murals need cellulose paste adhesive. Nice effort to assist the OP.

 

Different adhesives for different products is the general rule, though. The heavier the product, the more aggressive the choice of adhesive. Most paper murals must be hung with Cellulose. Most smaller murals (up to a regular sized bedroom wall with 8 panels) require the Cellulose.
