Double sided/spray adhesive

[Bex]

Hi everyone,

I am trying to print on double sided MDF and FRP using the 3M spray. No matter how light or far away I spray it, the finish is always mottled. I always clean the nozzle after each use too. Has anyone got any tips on double sided products as I have a customer wanting 150 keyrings.
Thank you in advance

Keyrings have to be taped in my experience.
It’s a pain but it’s the only way as spray adhesive will just ruin the print.

3M 75 spray only really good for fabrics, hard surfaces best using heat tape

Thank you both for your replies. I’m finding that the tape is lifting the print from the first side

It shouldn't do, once the print is on it should be permanent

if the print is lifting you have a very poor product.
