Best Paint or Sealant for Adhesive Wall Graphics?

We've found cheap semi-gloss paint is the easiest to stick to. It's the expensive stuff with additives for repelling stains and marks that tend to reject any adhesive vinyl.
But if you have your choice before they even paint, NO paint is the best option. Primed walls are great for graphics. Make sure they are smooth and dust free, clean with alcohol.

 

We do tons of dry erase vinyl. We always ask for an oil based primer or use Zinsser Gardz. We prefer Gardz because it's water based and it dry within 3 hours. So you can install the next day compared to oil based primer that you have to wait 6-10 days in average.

The dry erase vinyl is particular compared to regular vinyl because it contain a thin layer of polycarbonate (for most of the manufacturers). It has a tendency to pull off the wall particularly on the edges. Even if you use the 3M adhesion test kit and pass the test, it could be a problem. So you need an extra safety other than paint to have a great adhesion. This is why we recommend Gardz.
