  • Is there a product that will stick lifting vinyl back down to a wall?

    Posted by Simon Worrall on March 29, 2023 at 10:02 pm

    I got some lifting vinyl at the edge of a mural stuck to a painted wall (arlon 8000 agressive stick vinyl) and I want to stick it back down.

    Its lasted pretty well, considering the location.

    I tried 3m spray adhesive (both 77 and 90) but that lasts a few days then its back up.

    Is there anything else I could try?

    how about 3m tape onto the wall, then stick the vinyl onto it. I have some aggresive stuff that comes on sheets and sure that would be a fix. Obviously you would see a slight line where it is underneath depending on the type of mural vinyl but im sure thats not a huge problem. 3m300lse is the sheet number

    obviously, I cannot see the application you are faced with but…

    textured wall applications are “great” for hiding joins, the rougher the surface is, the better.

    Instead of trying to get bits to stick back down. it is better to just print a “patch”.

    Now let’s say you have a rough brick wall and you have stuck the following photo to it.

    one side is coming away top to bottom on the right, and the top left corner and a bit in the middle at the monkey’s teeth are all lifting. (highlighted with pink filter).
    * Take a sharp scalpel and “cut them out.” so your basically cutting away the parts that are lifting.
    * now print patches that are “oversized”.
    so if you have a section 100mm x 100mm and it’s coming away.
    * make your patch 120mm x 120mm.

    * make sure the bad section has been cut away clean.
    * make sure the wall is clean as possible.
    * do not use spray adhesive etc. make sure that’s also OFF the surface.

    * sit the patch in position, heat the vinyl and roll-conform it back into position with whatever you used to apply it.

    as I say, the rougher the wall surface the better the patch will be hidden.
    the only way you will see it is if the old print is badly faded and the new print is nice and vibrant, even then its a trade-off, for the print being back to its original condition.

    before doing any of the above.
    Print a small photo and a patch, in your workshop.
    stick it to a rough wall, then apply the patch, as above, you will not see it.

    Thanks.
    I dont know why I didnt think of reprinting the bits that are coming up. Seems obvious now you said it Rob!
    The simple fixes are the best.
    cheers Martin. I didnt know you could get 3m tape in sheets. I will use that on another job.
