  • Spray paint over vinyl wrap, advice needed?

    Morning all

    I wrapped a trailer the other week and the client has just informed me that the wrap has been graffitied over with spray paint.

    Is there anything that will remove this without damaging the wrap?

    Hi Dan

    you want to treat this in a sort of reverse form. by that, I mean “gentle to extreme” chemical break down.

    the easy solution is something like a paint thinner, but that will also bite into the vinyl surface and although it will remove the paint, it will severely dull the finish of the vinyl surface and look bad! in some cases, it can leave the wiped surface feeling tacky to touch.

    dependant on the type of paint or how thick the paint is. sometimes meths or isopropyl alcohol is enough to remove it without any damage to the vinyl surface.

    You could try a tar and glue remover, soak and leave for 15 minutes and repeat. this breaks down solvents etc in the adhesive so “may” have some chance. again, paint type etc I think will play a part in this.

    you could even try a form of white spirit, but again. chemicals like this must be “left to soak” for a period of time to help break down. then repeat. so generous amounts applied repeatedly over 10-minute spells would be advised.

    as I say, its a gentle approach that’s required or you run the risk of damaging the surface of the vinyl.

    if it’s not coming off and is only on a small area it may be best and to just re-wrap the area. as the chemicals being bought will outweigh the cost of the wrapping film if its only a metre or so.

    best of luck!

    I would be tempted to try a bit of T cut in a small test area to see if the paint could be removed that way

    @phill-fenton

    That may work Phill. the t-cut would maybe help break the seal on the surface of the paint. then maybe isopropanol or some other non-aggressive chemical to clean the paint.

    In days gone by before vinyl came out we used to use oven cleaner to remove signwriting, with differing results.

    Not that I ever did it, or needed to as I never did any traditional aspects of sign making or writing but I remember a few from this site many years ago swore by this. a few Americans too.
    My only worry about these types of products, is some have a fine scouring ingredient that may dull the sheen from the vinyl.
